How to use twitter api with "http basic auth"?
I think I should use the "consumer key"! because twitter gave you limit rate of requests per hour, how can they count my requests if I didn't use my consumer key?
Whenever you want to use HTTP basic auth with anything, if you want to ignore the actual implementation and HTTP headers, just use cURL. Here's a simple example in PHP, cURL is available in other languages too:
<?php
$ch = curl_init();
// Sets the URL cURL will open
curl_setopt($ch, CURLOPT_URL, 'http://twitter.com/statuses/user_timeline.xml?screen_name=al3x');
// Here's the HTTP auth
// The 3rd argument is your Twitter username and password joined with a colon
curl_setopt($ch, CURLOPT_USERPWD, 'username:password');
// Makes curl_exec() return server response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Lately the Twitter API expects an Expect header. It's a mystery
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
// And here's the result XML
$twitter_xml = curl_exec($ch);
curl_close($ch);
?>
And then $twitter_xml will contain the XML of al3x's public timeline. As far as rate limiting goes, ceejayoz already answered that pretty well.
Authenticated API GET requests are counted against your user account's tally.
Unauthenticated API GET requests (permitted by some methods) are counted against your IP address's tally.
POST requests are not rate limited.
More details are available in the Twitter docs.
I would think that they count the requests from the same IP - but I haven't double checked.
Even dynamic IP address will be static for a session and, in the absence of any other identifying information, the only thing that will distinguish you from other users.
As other posters have said - there are better methods if you've got a key.
$twitter = file_get_content("http://user:password#twitter.com/blabla");

I recently wrote some PHP to post to Twitter
This is the working part of it:
$message = 'A new revision (#' . $data['revision'] . ') was commited by ' . $data['author'] . ': ' . $data['message'] . "";
$message = substr($message, 0, 140);
$content = 'status=' . urlencode($message);
$packetString = "POST /statuses/update.xml HTTP/1.1\r\n";
$packetString .= "Authorization: Basic " . base64_encode($username . ":" . $password) . "\r\n";
$packetString .= "Content-Length:" . strlen($content) . "\r\n";
$packetString .= "HOST: twitter.com\r\n";
$packetString .= "\r\n" . $content . "\r\n";
$sock = fsockopen('twitter.com', 80);
fwrite($sock, $packetString);
//This is some logging, to a local file so I can monitor local what's going on
$response = fread($sock, 10240);
fwrite($fh, $packetString . "\r\n\r\n\r\n" . trim($response) . "\r\n\r\n\r\nD:\r\n" . $d);
fclose($fh);

I am implementing Bing Image Search API in php. I know that Bing API has been changed and now we have to involve that windows azure marketplace thing in-order to use the Bing Image Search API.
I have done that, which means i have opted for a free Bing Search Api subscription which gives me around 5000 transaction per month. Its going all good but the thing is the result which is being fetched is tend to get expired after say 1 month.
Here is the code i am using :
$key = "cricket";
// Replace this value with your account key
$accountKey = 'WEGUEed3yF9CI6ZzVblKD0HoMRG3/rOELkCda9VYsuk=';
$ServiceRootURL = 'https://api.datamarket.azure.com/Bing/Search/';
$WebSearchURL = $ServiceRootURL . 'Image?$format=json&Query=';
$request = $WebSearchURL . urlencode( '\'' . $key . '\'');
$process = curl_init($request);
curl_setopt($process, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($process, CURLOPT_USERPWD, $accountKey . ":" . $accountKey);
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($process);
$jsonobj = json_decode($response);
echo('<ul ID="resultList">');
foreach($jsonobj->d->results as $value)
{
echo('<li class="resultlistitem"><a href="' . $value->MediaURL . '">');
echo('<img src="' . $value->Thumbnail->MediaUrl. '"></li>');
}
echo("</ul>");
On running this program i am getting the results, I am getting the image source. But the thing is the image source doesn't seems to be a real image source i mean the URL is something like this :
http://ts4.mm.bing.net/th?id=HN.608026386931518543&pid=15.1
Also this link is expires after a month or so .... Initally i was able to see the image when clicking on the link but it expired after a month and now i can only see a greyish camera with a cross on it which means that the image source has been expired i guess.
If you can let me how can i restrict this thing and also is anything needs to done on the windows azure market place end to get things working for me .
Any help will be appreciated
Thanks
Fix for original images.
On the line 22, where are interpreted received and parsed JSON data
echo('<li class="resultlistitem"><a href="' . $value->MediaURL . '">');
there is a mistake from Bing.
You can just replace
$value->MediaURL for $value->MediaUrl
and you can get acquire access to original image.
I'm trying to call the DocuSign REST login information within a CodeIgniter application. The Docusign sample code shows:
// Input your info here:
$integratorKey = '...';
$email = '...#....com';
$password = '...';
$name = 'John Doe';
// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";
/////////////////////////////////////////////////////////////////////////////////////////////////
// STEP 1 - Login (to retrieve baseUrl and accountId)
/////////////////////////////////////////////////////////////////////////////////////////////////
$url = "https://demo.docusign.net/restapi/v2/login_information";
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("X-DocuSign-Authentication: $header"));
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ( $status != 200 ) {
echo "error calling webservice, status is:" . $status;
exit(-1);
}
I keep getting a status response of 0. When I echo out the curl all the xml tags have been converted to lowercase (which won't work with Docusign). Has anyone done this call within CodeIgniter? How did you accomplish it? I know my credentials are good because I can do a command line curl and get a response.
I'm not sure what CodeIgniter is doing and why the tags would be converted to lower case but you're right in that DocuSign expects xml tags to begin with a capital letter so that might not work. What you can do, though, is use JSON headers and request bodies instead.
For instance, instead of an XML formatted authentication header like
<DocuSignCredentials>
<Username>username</Username>
<Password>password</Password>
<IntegratorKey>integrator_key</IntegratorKey>
</DocuSignCredentials>
You could use the corresponding JSON auth header like
{
"Username": "username",
"Password": "password",
"IntegratorKey": "integrator_key"
}
The "nodes" still start with a capital but since it's not xml I'm wondering if CodeIgniter maybe leaves it alone. Examples of this can be found at the DocuSign Developer Center on this page.
I'm trying to figure out how to get this working with PHP. I have a working IPN for paypal that is less than 20 lines of code to get the data I need. I have tried reading the Google docs but they are either way too specific or way too general. There is some sample code, which is about 1300 lines in 5 files and I can't make sense of it. I just need a handful of vars back from a completed transaction, nothing more. Is it possible to do this with a few lines of code (and I mean without 1300 lines worth of "include" files) or is Google Checkout's process really that bulky?
Here's a bit of code I started. Not yet finished.
It works perfectly.
All you need to do is take the data Google sends back and this code writes to a file and use it to insert into your sales table send notification of payment received to customer and so on.
The trick is that when Google sends you a post you must call back with and Authorization header or it will not take it in consideration.
function post2google($url, $timeout = 30, $port = 80, $buffer = 128) {
$mid = "123456789";
$mky = "qwertyuiop";
$aut = base64_encode($mid . ":" . $mky);
$arr = parse_url($url);
$ssl = "";
if($arr['scheme'] == "https") $ssl = "ssl://";
$post = "POST " . $arr['path'] . " HTTP/1.1\r\n";
$post .= "Host: " . $arr['host'] . "\r\n";
$post .= "Authorization: Basic " . $aut . "\r\n";
$post .= "Content-Type: application/xml; charset=UTF-8\r\n";
$post .= "Accept: application/xml; charset=UTF-8\r\n";
$post .= "Content-Length: " . strlen($arr['query']) . "\r\n";
$post .= "Connection: Close\r\n";
$post .= "\r\n";
$post .= $arr['query'];
$f = fsockopen($ssl . $arr['host'], $port, $errno, $errstr, $timeout);
if(!$f)
return $errstr . " (" . $errno . ")";
else{
fputs($f, $post);
while(!feof($f)) { $echo .= #fgets($f, $buffer); }
fclose($f);
return $echo;
}
}
$re = post2google("https://checkout.google.com/api/checkout/v2/reportsForm/Merchant/123456789?_type=notification-history-request&serial-number=" . $_REQUEST['serial-number'], 3, 443);
$re = str_replace("&", "\n", $re) . "\n\n--\n\n";
file_put_contents("gpn.txt", $re, FILE_APPEND);
I've gotten it to work, and here's the skeleton of my code that can be used to handle HTTP notifications/responses. This was obviously derived from tntu's example above. (Thanks!)
//incoming data is in the var $_POST['serial-number']
//"send" the response to acknowledge the serial number that google talks about all over but never explains how
echo "_type=notification-acknowledgment&serial-number=".$_POST['serial-number'];
//now we need to call google's server and ask for this transaction's data:
//you'll need to change your merchant id in the $url and $mid vars, and your merchant key in the $mky var
$url = "https://sandbox.google.com/checkout/api/checkout/v2/reportsForm/Merchant/1234567890?_type=notification-history-request&serial-number=" . $_REQUEST['serial-number'];
$mid = "1234567890";
$mky = "ABCDEFGHIJK";
$aut = base64_encode($mid . ":" . $mky);
$arr = parse_url($url);
$ssl = "";
if($arr['scheme'] == "https") $ssl = "ssl://";
$post = "POST " . $arr['path'] . " HTTP/1.1\r\n";
$post .= "Host: " . $arr['host'] . "\r\n";
$post .= "Authorization: Basic " . $aut . "\r\n";
$post .= "Content-Type: application/xml; charset=UTF-8\r\n";
$post .= "Accept: application/xml; charset=UTF-8\r\n";
$post .= "Content-Length: " . strlen($arr['query']) . "\r\n";
$post .= "Connection: Close\r\n";
$post .= "\r\n";
$post .= $arr['query'];
//now we actually make the request by opening a socket and calling Google's server
$f = fsockopen($ssl . $arr['host'], 443, $errno, $errstr, 30);
if(!$f){
//something failed in the opening of the socket, we didn't contact google at all, you can do whatever you want here such as emailing yourself about it and what you were trying to send, etc
#mail("troubleshooting#yourdomain.com","Google IPN - HTTP ERROR ",$errstr . " (" . $errno . ")\n\n\n".$arr['query']);
}else{
//the socket was opened, send the request for the order data:
fputs($f, $post); // you're sending
while(!feof($f)) { $response .= #fgets($f, 128); } //google replies and you store it in $response
fclose($f); //close the socket, we're done talking to google's server
$spl=strpos($response,"_type="); //parse the type because parse_str won't catch it
if ($spl!==false){
$spl2=strpos($response,"&",$spl);
$ordertype=substr($response,($spl+6),($spl2-$spl)-6);
}//$ordertype will tell you which type of notification is being sent, new-order-notification, risk-information-notification, etc
$subresponse=substr($response,$spl2+1); //put the rest of it into an array for easy access
parse_str($subresponse,$order);//you can now access google's response in $order[] vars
//IMPORTANT: dots in Google's field names are replaced by underscore, for example:
// $order['google-order-number'] and $order['buyer-billing-address_address1'] NOT $order['buyer-billing-address.address1']
//order field names are shown here:
//https://developers.google.com/checkout/developer/Google_Checkout_HTML_API_Notification_API#order_summary
//this is the point where you will want to use the data contained in $order[] to create a new record in your database or whatever.
//NOTE: be sure to store and check for duplicates using the google-order-number because you will get multiple notifications from google regarding the same order
if (strtoupper($order['order-summary_financial-order-state']) == "CHARGEABLE"){
//CHARGEABLE is what indicates it is safe to create a login for the user (if you are delivering digital goods)
// insert into db, and/or email user with key or download url

I need to implement BeanStream payment gateway in my php code.I am new in payment gateway implementation. Can anybody help me with any demo project or scripts? prior thanks.
I know this is an old question, but since I just implemented the Beanstream payment gateway in my code I thought I would answer for the record anyway:
Once you have an account with Beanstream you will be able to access their API manuals which provide some good documentation on all of the request and response fields. You can use the curl library in PHP to connect to the Beanstream API this very easily. Here is a sample method for performing a simple payment based on their documentation ($global_ccauth is just an ORM object that contains my request information, which I store each time in my database, including the response string from Beanstream, but BE CAREFUL AND YOU PROBABLY WANT TO obfuscate the credit card number in the ORM model before it is saved to the database, like I do):
public static function do_payment($global_ccauth, $submitted_card_number) {
$payment_result = array(
'status' => FALSE,
'response' => array(),
);
// attempt to process the payment using CURL and a POST request to the Beanstream server as per Beanstream's example
$request = curl_init();
// Get curl to POST
curl_setopt($request, CURLOPT_POST, 1);
curl_setopt($request, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($request, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // return the results instead of echoing them
curl_setopt($request, CURLOPT_URL, BEANSTREAM_URL);
// These are the transaction parameters that we will POST
$auth_parameters = "requestType=BACKEND";
$auth_parameters .= "&merchant_id=" . BEANSTREAM_MERCHANT;
$auth_parameters .= "&username=" . BEANSTREAM_API_USER;
$auth_parameters .= "&password=" . BEANSTREAM_API_PASS;
$auth_parameters .= "&trnCardOwner=" . $global_ccauth->trnCardOwner;
$auth_parameters .= "&trnCardNumber=". $submitted_card_number;
$auth_parameters .= "&trnExpMonth=" . $global_ccauth->trnExpMonth;
$auth_parameters .= "&trnExpYear=" . $global_ccauth->trnExpYear;
//$auth_parameters .= "&trnCardCvd=";
$auth_parameters .= "&trnOrderNumber=" . $global_ccauth->trnOrderNumber ;
$auth_parameters .= "&trnAmount=" . $global_ccauth->trnAmount;
$auth_parameters .= "&ordName=" . $global_ccauth->ordName;
$auth_parameters .= "&ordEmailAddress=" . $global_ccauth->ordEmailAddress;
$auth_parameters .= "&ordPhoneNumber=" . $global_ccauth->ordPhoneNumber;
$auth_parameters .= "&ordAddress1=" . $global_ccauth->ordAddress1;
$auth_parameters .= "&ordAddress2=" . $global_ccauth->ordAddress2;
$auth_parameters .= "&ordCity=" . $global_ccauth->ordCity;
$auth_parameters .= "&ordProvince=" . $global_ccauth->ordProvince;
$auth_parameters .= "&ordPostalCode=" . $global_ccauth->ordPostalCode;
$auth_parameters .= "&ordCountry=" . $global_ccauth->ordCountry;
curl_setopt($request, CURLOPT_POSTFIELDS, $auth_parameters);
// Now POST the transaction. $txResult will contain Beanstream's response
$auth_result = curl_exec($request);
curl_close($request);
if ($auth_result !== FALSE) {
// save the raw results
$global_ccauth->response = $auth_result;
$global_ccauth->save();
// parse the results
parse_str($auth_result, $parsed_result);
$payment_result['response'] = $parsed_result;
if ( ! empty($parsed_result['trnApproved']) && $parsed_result['trnApproved'] == 1) {
// the request was approved
$payment_result['status'] = TRUE;
} else {
// the request was not approved
// do something smart
}
} else {
// curl POST request failed
// do something smart
}
return $payment_result;
}
I have also implemented their recurring payments for processing monthly payments automatically and it seems to be working well. You just have to adjust the parameters you send as per their API documentation.

I am currently developing a very basic site which will, at this time, simply display order information from Amazon's Marketplace.
I have all of the MWS Security Credentials.
I have downloaded and reviewed, with much confusion, the PHP Client Library.
I am kind of new to PHP but I feel like I can handle this project.
I need to know how to install and access information from this API. I feel like I've tried everything. Amazon does not supply enough information to get this going. They make it sound like it takes 5 or 6 easy steps and you can access your information; this is not true.
Is there a detailed tutorial on MWS? I need as much information as possible. If you can help me out, maybe outline the steps required to get it going, that would be very appreciated!!!! I'm pulling my hair out over this. Thanks again
A rough file to get you started. This is taken from several pages, including this one from #Vaidas. I don't have links yet, sorry. My only contribution is to put this together in one place.
None of the PHP code Amazon supplied worked for me out of the box. I'm assuming you have XAMPP with cURL or an equivalent environment. This code SHOULD work out of the box to get you started on what needs to happen. Just plug in your credentials.
<?php
$param = array();
$param['AWSAccessKeyId'] = 'YourAccessKeyID';
$param['Action'] = 'GetLowestOfferListingsForASIN';
$param['SellerId'] = 'YourSellerID';
$param['SignatureMethod'] = 'HmacSHA256';
$param['SignatureVersion'] = '2';
$param['Timestamp'] = gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time());
$param['Version'] = '2011-10-01';
$param['MarketplaceId'] = 'YourMarketplaceID';
$param['ItemCondition'] = 'new';
$param['ASINList.ASIN.1'] = 'B00C5XBAOA';
$secret = 'YourSecretKey';
$url = array();
foreach ($param as $key => $val) {
$key = str_replace("%7E", "~", rawurlencode($key));
$val = str_replace("%7E", "~", rawurlencode($val));
$url[] = "{$key}={$val}";
}
sort($url);
$arr = implode('&', $url);
$sign = 'GET' . "\n";
$sign .= 'mws.amazonservices.com' . "\n";
$sign .= '/Products/2011-10-01' . "\n";
$sign .= $arr;
$signature = hash_hmac("sha256", $sign, $secret, true);
$signature = urlencode(base64_encode($signature));
$link = "https://mws.amazonservices.com/Products/2011-10-01?";
$link .= $arr . "&Signature=" . $signature;
echo($link); //for debugging - you can paste this into a browser and see if it loads.
$ch = curl_init($link);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo('<p>' . $response . '</p>');
print_r('<p>' . $info . '</p>');
?>
Please note that it is VITAL to have the
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
line, at least in my case. CURL was working fine for any page except for the MWS page (it was just giving me a blank page with -1s in the info, and it took me most of a day to figure out I needed that line. It's in the MWS forums somewhere.
For good measure, here's a link to MWS ScratchPad.
Once I get a better handle on working with MWS maybe I'll do a tutorial. Or someone who is better at HTML and has a need for more of the features could do it.
in case you still didn't figure out how to do this, follow these steps
read the Developer Guide
read the Reports API Reference
RequestReport with some ReportType that will return order data (page 51 or so, look the reports api reference)
you can test this with the MWS Scratchpad
you can also post to the Amazon MWS community forum to get additional help
you can even write to the Amazon Tech Support
hope this helps you and other users.
Amazon provides some great sample code at https://developer.amazonservices.com/. I've successfully used their code for my PHP applications.
I agree. It was a nightmare to figure out the MWS API.
Some changes to #Josiah's method to make it work for other marketplaces:
Line:
$sign .= 'mws.amazonservices.com' . "\n";
Change to: your correct MWS endpoint. List here http://docs.developer.amazonservices.com/en_US/dev_guide/DG_Endpoints.html - it'll match your marketplace ID, which could be something like this:
$sign .= 'mws-eu.amazonservices.com' . "\n";
and UK marketplace ID for UK site.
Line:
$link = "https://mws.amazonservices.com/Products/2011-10-01?";
Again, change the start of the url in line with above.
This'll probably give you straight text output in a browser (view source for xml). For XML visible output (easier for checking) do this:
Add an XML content type line to top of file:
header('Content-type: application/xml');
Then comment out:
echo($link);
and
print_r('<p>' . $info . '</p>');
Implementing MWS is easy if you follow the right steps:
1-Download the codebase library from the https://developer.amazonservices.com/ as per your preferred language.
2-Set your seller mws credentials in config.php file under sample folder so that same can be used while running the specific file under the sample folder like: RequestReportSample.php and set the report type and endpoint url for specific seller domain.
3- You can then check submitted request status from scratchpad.
4- You can use GetReportSample file to get the order report data and use the same as per your need.
You can follow the reference as well http://prashantpandeytech.blogspot.com/2015/03/mws-amazon-marketplace-web-service-api.html
