I am trying to read the response (json text) from server. But the server returns the response as a file which gets downloaded in my downloads directory.
url:-https://www.googleapis.com/freebase/v1/mqlread?query=%5B%7B%22id%22%3Anull%2C%22name%22%3Anull%2C%22type%22%3A%22%5C%2Fastronomy%5C%2Fplanet%22%7D%5D
I am using curl in my php code.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Connection: Keep-Alive'
));
$response = json_decode(curl_exec($ch), true);
curl_close($ch);
How can I read the data using php curl?
UPDATE: When I try to run the same code in online editors like http://phpassist.com/ then it reads the data and shows me the required output.
So is there any additional configuration I need to make in XAMPP??
Tks
You need disable ssl certification or get ssl certification, the fastest way is:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

I have php file which consist of curl code so as to access an api. But when I upload this file on server and try to execute it via url no output is shown. Also file symbol is not shown as it is shown for php file. Guide me how to solve this problem. The code in php file is :
<?php // set up the curl resource
$ch = curl_init(); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch,CURLOPT_POSTFIELDS,"{}"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, 'http://184.73.165.170:3000/api/3ace632b194e4366b821f7775b51cc4e/get-ibeacon-contents'); // execute the request
$output = curl_exec($ch);
// output the profile information - includes the header
//echo "curl response is :".($output). PHP_EOL; print($output);
// close curl resource to free up system resources
curl_close($ch); ?>
My server index shows as shown in image. As per my understanding a php file symbol is different than what it is shown in image I uploaded. Can anyone suggest about this ,if it helps me resolve my aim.
I tried on local and the cURL seems to work. If its working on local only and not on server then these are the things you should check:
Enable cURL on server ;extension=php_curl.dll and remove the semicolon; (uncomments) usually inside file php/php.ini
If you are working locally on Windows and trying to upload to a Linux server, then you might want to change EOL for UNIX/OSX Format. You can do this using Notepad++ by going to Edit -> EOL Conversion -> UNIX/OSX Format and then upload.
Try using your code this way
<?php
$json=json_encode(array('key1'=>'val1','key2'=>'val2'));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://184.73.165.170:3000/api/3ace632b194e4366b821f7775b51cc4e/get-ibeacon-contents');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS,$json);
$output = curl_exec($ch);
var_dump(curl_getinfo($ch));
echo curl_errno($ch) . '-' . curl_error($ch);
curl_close($ch);
?>
I'm a bit of a beginner to this. But I am trying to use cURL to perform a GET request to pull back users tweets.
I've been able to authenticate OK. But I cannot work out how to GET the data. I'm working from my localhost.
I've tried adding a basic certificate but it does not work.
Do I have to buy an SSL certificate for my site? I've seen twitter feeds on other sites that haven't purchased SSL certificates so I don't know how they do it?
I've seen this in the Twitter documentation. The file that is mentioned, is that the one I can purchase?
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, True);
curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($connection, CURLOPT_CAINFO, "path:/ca-bundle.crt");
This is my cURL code, it worked before I put the CURLOPT_URL section in and got a positive response from the server:
$url = "https://api.twitter.com/oauth2/token";
$headers = array(
"POST /oauth2/token HTTP/1.1",
"Host: api.twitter.com",
"User-Agent: my Twitter App v.1",
"Authorization: Basic ".$encoded."",
"Content-Type: application/x-www-form-urlencoded;charset=UTF-8"
);
$ch = curl_init();
curl_setopt ($ch, CURLOPT_CAINFO, "cacert.pem");
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
curl_setopt($ch, CURLOPT_URL, "http://twitter.com/statuses/user_timeline/".$username.".json?count=".$num_tweets);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$header = curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$output = curl_exec($ch);
curl_close($ch);
Edit: there are problems with the code above, I'm aware I'm doing something wrong but not sure what. Anyway, here is the original code I had which did work OK and got the expected result back from the server. So the next step is to request the user's tweets from their timeline.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
$header = curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
You may use curl_getinfo to know what's going on.
You may also post the url of the Twitter documentation so we can have a look.
$headers indicates a host as api.twitter.com but CURLOPT_URL uses twitter.com, is this a typo ?
Your code is schizophrenic:
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_URL, "http://twitter.com/statuses/user_timeline/".$username.".json?count=".$num_tweets);
You're setting the URL twice, to different URLs. Only the LAST url set will have any effect, so you're not posting to the API, you're posting to something else on the main twitter site.
And no, you don't need an SSL cert on your own machine to do any of this. The ca-cert.pem is a list of cert issuer's public certs, which will be used to validate/authenticate Twitter's own certificate. It's basically the same thing built into your browser(s) that allow them to validate any other SSL cert out there. e.g. you don't have to buy a personal SSL cert to go shopping on amazon.com, you just need the CA certs in your browsers to authenticate amazon's servers.
Is it possible to do a cURL request with the PUT method using only a URL? Here is the URL i would like to be able to call using cURL with the PUT method:
$url = https://url.net/card/activate.xml?card_id=1234567890&application_key=123123&accesskey=abcdef
I was able to make it work using the REST Console(Chrome Extension) but not using cURL. I tried using curl_setopt with CURLOPT_PUT, CURLOPT_INFILE and CURLOPT_INFILESIZE but I was receiving an empty page, no response at all.
This is the headers and curl options I currently have:
$header[] = 'Authorization: Basic abc123';
$header[] = 'Accept: text/xml';
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($soap_do);
Currently, with those settings, I'm getting the 411 Length Required error. Would it be possible to make it work like that or am I trying to configure something that will never work?
The HTTP 411 Error
The Web server (running the Web site) thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) should include a 'Content-Length' specification. This is typically used only for HTTP methods that result in the placement of data on the Web server, not the retrieval of data from it.
You need to set the Content Length of your Data
$header[] = 'Content-length: '.strlen($put_data);
OR If you don't have any data, just put 0 there.
I'm trying to get response using the Google Safe Browsing Lookup API like this:
$url ="https://sb-ssl.google.com/safebrowsing/api/lookup?client=myappname&apikey=mykey&appver=1.0&pver=3.0&url=".urlencode($myurl);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
$body = curl_exec($ch);
$info = curl_getinfo($ch);
I know that my URL is correct since if I dump it and then paste it to the browser I get the expected result (for example 'malware').
So I am assuming it must be something with cURL. I'm working on localhost and extension=php_curl.dll is un-commented in my php.ini, Php version 5.4.4
The html_code is always 0
Simply set CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST to false.
Anything wrong with my cURL code (http status of 0)?
Also check http://code.google.com/p/twitter-api/issues/detail?id=1291 , it might help. It is different APIs, but with the same problem anyway.
The problem and its solution is very nicely described here:
http://richardwarrender.com/2007/05/the-secret-to-curl-in-php-on-windows/
Basically if you are not using a standalone version of cURL the chances are that the cURL functions do not include a certificate bundle which was needed in my case since I was trying to connect to secure host.
$ch = curl_init();
// Apply various settings
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CAINFO, "C:/xampp/ca-bundle.crt"); //path to the CA-bundle
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($ch);
curl_close($ch);
I've spent hours troubleshooting this utilizing PHP documentation, the API documentation, as well as other posts on stackoverflow, and am finally asking for help.
I am attempting to write an interface utilizing the new pbSmartConnections API: API Documentation
I have been having challenges with both fsockopen and cURL, however I seem to be able to get farther in the process utilizing cURL, so that's what I'm presenting here. Here's the challenge:
Per my understanding of the documentation, I should be passing the ApiKey as part of the header. When I do this, regardless of the different ways I've attempted to structure the code, I ALWAYS receive the following response:
{
"ErrorCode": 10,
"Message": "Unauthorized"
}
I'm hoping a fellow SO member can see something in my code below (please offer any criticisms and/or suggestions, too!):
(NOTE: The API key below IS valid. It's connected to an account with nothing of value in it, so feel free to use it in your testing)
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://rest.pbsyscontrol.com/v1/Ping");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type"=>"application/json", "Accept"=>"application/json", "ApiKey"=>"41460b3f-8f35-4878-b78d-49ca7f29c071"));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPGET, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
?>
In case you are wondering, while I would like this to work as part of the header, I HAVE tried passing it as a part of the URL as well:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://rest.pbsyscontrol.com/v1/Ping?ApiKey=41460b3f-8f35-4878-b78d-49ca7f29c071");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type"=>"application/json", "Accept"=>"application/json", "ApiKey"=>"41460b3f-8f35-4878-b78d-49ca7f29c071"));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPGET, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
?>
The PHP documentation says:
An array of HTTP header fields to set, in the format array('Content-type: text/plain', 'Content-length: 100')
You thus want to use the following line instead of the original:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Accept: application/json", "ApiKey: 41460b3f-8f35-4878-b78d-49ca7f29c071"));
This does not however, solve the problem that the ApiKey probably isn't valid.
I finally heard back from support, and what they indicated was that I was using the incorrect url (although at this time, it IS the url in their API Documentation)
The URL in the API documentation was their STAGING, not PRODUCTION. Amazing what switching the URL to the correct one that they sent in their reply - rest.api.pbsmartconnections.com does for the connection. That one change and everything began working properly.
THANK YOU all who took a look, and to #mvdnes for the recommendations on how to set headers.
