I downloaded Product Advertising PHP Soap Library and was going through the sample codes. I configured the value of 'AWS_API_KEY', 'AWS_API_SECRET_KEY', 'AWS_ASSOCIATE_TAG', 'AWS_ANOTHER_ASSOCIATE_TAG' in sampleSettings.php file. I'm getting the below mentioned error in my browser while trying to access 'sampleItemSearch.php'.
SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl' : Start tag expected, '<' not found
I tried to take help help from Link: https://forums.aws.amazon.com/thread.jspa?messageID=270273 but it did not work.
Note: I have tried to run the below url in browser and got the following output:
$request="http://webservices.amazon.com/onca/xml?Service=AWSECommerceService&AssociateTag=ASSOCIATETAG01-20&AWSAccessKeyId=MY_ACCESS_KEY_ID&Operation=ItemSearch&Version=2011-08-01&SearchIndex=Books&Keywords=harry%20potter&Timestamp=2013-04-10T12%3A44%3A42.000Z&Signature=ASasd5645AdSG878asdHsaHJ9YTefl1F6i0%3D";
Please suggest what I should do.
I solved it at last. Below mentioned code is working fine.
AWSAccessKeyId = "*******************";
$SecretAccessKey = "******************************";
$AssociateTag = "***************";
$ItemId = '****'; //10 or 13 digit isbn
$Timestamp = gmdate("Y-m-d\TH:i:s\Z");
$Timestamp = str_replace(":", "%3A", $Timestamp);
$ResponseGroup = "ItemAttributes,Images";
$ResponseGroup = str_replace(",", "%2C", $ResponseGroup);

$String = str_replace("\n", "", $String);
$Prepend = "GET\nwebservices.amazon.com\n/onca/xml\n";
$PrependString = $Prepend . $String;

OK... I am using PHP 5 (be gentle, still learning PHP). CURL is enabled. Attempting to load XML or JSON output from an API to an object and nothing happens. When I manually execute the URL in question, I get what I am expecting.
Here is my code:
class XmlToJson {
public function Parse ($url) {
$fileContents = file_get_contents($url);
$fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
$fileContents = trim(str_replace('"', "'", $fileContents));
$simpleXml = simplexml_load_string($fileContents);
$json = json_encode($simpleXml);
return $json;
}
}
$_MySQLServer = "localhost";
$_MySQLServerUserName = "";
$_MySQLServerPassword = "";
$_MySQLDatabaseName = "";
$_SSActiveWear_UserID = "*****";
$_SSActiveWear_APIKey = "*****";
$_SSActiveWear_APIBaseURL = "https://*****/v2";
$_CategoryURL = "/categories/";
$_StylesURL = "/styles/";
$_ProductsURL = "/products/";
$_SpecsURL = "/specs/";
$_SSActiveWear_MediaType = "xml";
//$_conn = mysqli_connect($_MySQLServer, $_MySQLServerUserName, $_MySQLServerPassword, $_MySQLDatabaseName);
//Insert or Update Categories
$_URL = $_SSActiveWear_APIBaseURL . $_CategoryURL;
$_URL = $_URL . "?mediatype=$_SSActiveWear_MediaType&UserName=$_SSActiveWear_UserID&Password=$_SSActiveWear_APIKey";
$OBJ = simplexml_load_string($_URL);
print_r($OBJ);
What am I doing wrong?
Edit 1
Added the following code:
$xml = simplexml_load_file($_URL) or die("Error: Cannot create object");
print_r($xml);
and it dies. Does that mean that there is something wrong with the code?
Try this :
$OBJ = simplexml_load_string(file_get_contents($_URL));
If you want to know why your code is not working, you are trying to load XML from URL but "simplexml_load_string" loads XML from string.
I FINALLY figured it out... More to the point I finally found a site on Google that helped. It is the first answer in fsockopen with http authentication problem.
So here is the code that works:
file_get_contents("https://$_SSActiveWear_UserID:$_SSActiveWear_APIKey#$_SSActiveWear_APIBaseURL$_CategoryURL/?mediatype=$_SSActiveWear_MediaType");
mediatype can be either json or xml
So despite hours of fiddling I cannot understand why my JSON query only returns a result for the last line in the CSV/TXT files I am trying to parse.
Here is the code:
//Enter API Key Here
$api_key = 'AIzaSyB9Dq3w1HCxkS5qyELI_pZuTmdK8itOBHo';
$origin = 'RG12 1AA';
$output_type = 'json'; //xml or json
$csv_location = 'http://www.naturedock.co.uk/postcodes.csv';
//Do not edit
$base_url = 'https://maps.googleapis.com/maps/api/directions/';
$origin_url = '?origin=';
$destination_url = '&destination=';
$end_url = '&sensor=false&key=';
$page = join("",file("$csv_location"));
$kw = explode("\n", $page);
for($i=0;$i<count($kw);$i++){
$destination = $kw[$i];
echo $destination;
$raw_url = $base_url . $output_type . $origin_url . $origin . $destination_url . $destination . $end_url . $api_key;
$request_url = str_replace(' ', '', $raw_url);
$getJson = file_get_contents($request_url);
$routes = json_decode($getJson);
$result = $routes->routes[0]->legs[0]->distance->value;
echo $result . '<br>';
}
The result I get looks like this:
Distance by Post Code Generator v0.1 by Phil Hughes
RG12 0GA
RG12 0GB
RG12 0GC
RG12 0GD4066
Where the '4066' is the correct variable for RG12 0GD postcode but none of the others return results as you can see.
Please help.
Your
join("",file("$csv_location"));
concatenated all lines feom the file to a single line without separator. The following explode() sees no newlines any more. So you are working on one line only. count($kw) always evaluates to 1 and your loop runs only one time.
I have looked at most samples of code based on this issue on stack overflow but I still cant get the request to work. I keep getting this error:
<Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
Here is my code:

$secretkey = "SECRET_KEY";
$keywords = "harry%20potter";

$the_string=$operation.$timestamp;
return base64_encode(hash_hmac("sha256",$the_string,$secretkey,true));
}
$signature = createSignature ($operation,$timestamp,$secretkey);

Can anyone help?
I had this issue long time and it worked for me with this code :
require_once 'Crypt/HMAC.php';
require_once 'HTTP/Request.php';
$keyId = "adasdasd";
$secretKey = "asdasdasdasdasd+";
function hex2b64($str) {
$raw = '';
for ($i=0; $i < strlen($str); $i+=2) {
$raw .= chr(hexdec(substr($str, $i, 2)));
}
return base64_encode($raw);
}
function constructSig($str) {
global $secretKey;
$str = utf8_encode($str);
$secretKey = utf8_encode($secretKey);
$hasher =& new Crypt_HMAC($secretKey, "sha1");
$signature = hex2b64($hasher->hash($str));
return ($signature);
}
$expire = time()+1000;
$resource = "/demo/files/clouds.jpg";
$date = gmdate("D, d M Y G:i:s T");
$mime = "image/jpeg";
$stringToSign = "PUT\n";
$stringToSign .= "\n";
$stringToSign .= "$mime\n";
$stringToSign .= "$date\n";
$stringToSign .= $resource;
$req =& new HTTP_Request("http://nameofmine.s3.amazonaws.com/files/clouds.jpg");
$req->setMethod("PUT");
$req->addHeader("Date",$date);
$req->addHeader("Authorization", "AWS " . $keyId . ":" . constructSig($stringToSign));
$req->addHeader("Content-Type",$mime);
$req->setBody(file_get_contents($file_path));
$req->sendRequest();
$responseCode = $req->getResponseCode();
$responseString = $req->getResponseBody();
echo $responseCode;
As you see you have to use Crypto, HTTP pear plugins
The function seems ok (it is the same as the one used in amazon AWS SDK) so make sure that there is no whitespace in front or after the copied key.
When I typed in my credentials by hand, I got the same error a couple of times.
Then I tried Console for Windows so I could copy/paste my credentials. This removed the error message. Either I sucked at typing, or sucked at reading.
Long story short: Don't type by hand, copy and past credentials to avoid typos.
EDIT:
My problem was when trying to add my credentials via EB CLIx3.
I'm trying to fetch a list of results for a search through Amazon API to list products on my website. Everything works except for specifying the page number that I want to retrieve. It always fetches page 1 for some reason.
$SecretAccessKey = "xxx";
$request['AWSAccessKeyId'] = "xxx";
$request['AssociateTag'] = "xxx";
$request['Timestamp'] = gmdate("Y-m-d\TH:i:s\Z");
$request['ResponseGroup'] = "ItemAttributes,Offers,Images";
$request['ItemPage'] = 1;
$request['Service'] = 'AWSECommerceService';
$request['Version'] = '2011-08-01';
$request['Operation'] = 'ItemSearch';
$request['SearchIndex'] = $search['category_name'];
$request['Keywords'] = $search['text'];
$request['Page'] = 5;
ksort($request); // Sorts in order of key
$Prepend = "GET\nwebservices.amazon.com\n/onca/xml\n";
$String = http_build_query($request);
$PrependString = str_replace('+', '%20', $Prepend . $String);
$Signature = base64_encode(hash_hmac("sha256", $PrependString, $SecretAccessKey, True));
$Signature = urlencode($Signature);
$BaseUrl = "http://webservices.amazon.com/onca/xml?";
$SignedRequest = $BaseUrl . $String . "&Signature=" . $Signature;
// Fetch the generated URL
$xml = simplexml_load_file($SignedRequest);
I've tried with $request['Page'], $request['page'], $request['Pages'] and $request['pages']. None seem to work to pull the correct page. Does anyone know what this parameter is supposed to be named?
Turns out it was ItemPage.
$request['ItemPage'] = 5;
I am trying to purge a file through the MaxCDN API but it's not working. Here's the code I'm using. The print_r doesn't return any result.
function purge() {
date_default_timezone_set('America/Los_Angeles');
$date = date('c');
$apiid = 'myapiid';
$apikey = 'myapi';
$auth_key = hash('sha256', $date.':'.$apikey.':purge');
$url = 'http://softsailor.alexdumitru.netdna-cdn.com/wp-content/themes/ss3/includes/sprite.jpg';
if (!class_exists('IXR_Client')) {
require_once (ABSPATH . WPINC . '/class-IXR.php');
}
$client = new IXR_Client('api.netdna.com','/xmlrpc/cache',80);
$client->timeout = 30;
$client->query('cache.purge', $apiid, $auth_string, $date, $url);
print_r($client->getResponse());
}
I turned debug on and I'm getting the following error
Something went wrong - -32300 : transport error - HTTP status code was not 200
Hey Alex. I work at MaxCDN and here is a code example that I took from our Wiki:
<?php
date_default_timezone_set('America/Los_Angeles');
include("lib/xmlrpc.inc");
$cur = date('c');
$apiKey = 'api-key';
$apiUserId = 'api-user-id';
$namespace = 'cache';
$method = 'purge';
$authString = hash('sha256', $cur . ':' . $apiKey . ':' . $method);
// this is the url to purge
$url= 'http://static.jdorfman.netdna-cdn.com/static/images/frugal-it-logo.png';
$f=new xmlrpcmsg("$namespace.$method", array(php_xmlrpc_encode($apiUserId),
php_xmlrpc_encode($authString), php_xmlrpc_encode($cur),
php_xmlrpc_encode($url)));
$c=new xmlrpc_client("/xmlrpc/cache", "api.netdna.com", 80,'http11');
$r=&$c->send($f);
print_r($r);
?>
If you have any other questions or concerns feel free to get in contact with me: jdorfman at maxcdn dot com
jdorfman's example dumps the entire raw response but if you are like me you want to get it into data objects using php
Here are some helpful tips:
$r->serialize() to access just the raw XML response
to convert to JSON use this:
$xml = simplexml_load_string($r->serialize());
echo json_encode($xml);
