I'm trying to fetch a file from a server that requires authentication. I have the following PHP code:
//Import categories
$url = "http://$username:$password#www.example.com";
$categoriesXML = file_get_contents($url);
var_dump($url . " > " . $categoriesXML);
return;
The output of this page is merely: string(22) "Authorization Required". I also tried with:
$context = stream_context_create(array('http' => array('header' => "Authorization: Basic " . base64_encode("$username:$password"))));
$url = "http://www.example.com";
$categoriesXML = file_get_contents($url, false, $context);
var_dump($categoriesXML);
return;
I tried with cURL as well with the following code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
var_dump($output);
return;
The cURL returns a 301 code in the $info and the $output is empty. I'm a PHP/server newbie, what am I doing wrong?
The OP's problem was due to choosing the wrong HTTP auth mechanism. Setting CURLOPT_AUTH to CURLAUTH_BASIC or the more permissive CURLAUTH_ANY proved to solve the problem.

why some url with json content return null on php function get page content?
i used these ways :
file_get_content
curl
http_get
but return null . but when page open with browser json content show on browser ?? anyone can help me?
$url = 'https://pardakht.cafebazaar.ir/devapi/v2/api/validate/com.pdgroup.insta/inapp/coin_follow_1/purchases/324234235/?access_token=9IaRpdmQzFppJMabLHbHyzBaQnm8bM';
$result = file_get_content($url);
return null but in browser show
{"error_description": "Access token has expired.", "error": "invalid_credentials"}
It returns the following:
failed to open stream: HTTP request failed! HTTP/1.1 401 UNAUTHORIZED
So, you have to be authorized.
You ca play with this code snippet (I can't test since token expired again):
<?php
$access_token = "s9spZax2Xrj5g5bFZMJZShbMrEVjIo"; // use your actual token
$url = "https://pardakht.cafebazaar.ir/devapi/v2/api/validate/com.pdgroup.insta/inapp/coin_follow_1/purchases/324234235/";
// Solution with file_get_contents
// $content = file_get_contents($url . "?access_token=" . $access_token);
// echo $content;
// Solution with CURL
$headers = array(
"Accept: application/json",
"Content-Type: application/json",
"Authorization: Basic " . $access_token
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $url); // . $params - if you need some params
curl_setopt($ch, CURLOPT_POST, false);
// curl_setopt($ch, CURLOPT_USERPWD, $userPwd);
$result = curl_exec($ch);
$ch_error = curl_error($ch);
$info = curl_getinfo($ch);
curl_close($ch);
if ($ch_error) {
throw new Exception("cURL Error: " . $ch_error);
}
if ($info["http_code"] !== 200) {
throw new Exception("HTTP/1.1 " . $info["http_code"]);
}
echo $result;
I am trying to call Natural Language Understanding Watson API from my PHP code using curl. I have successfully tried curl from terminal. It gives some result on executing this command:
curl -u "my_username":"my_password" "https://gateway.watsonplatform.net/natural-language-understanding/api/v1/analyze?version=2017-02-27&text=I%20still%20have%20a%20dream.&features=sentiment,keywords"
However when I try to use curl in php using this code:
<?php
$url = "https://gateway.watsonplatform.net/natural-language-understanding/api/v1/analyze?version=2017-02-27&text=I%20still%20have%20a%20dream%2C%20a%20dream%20deeply%20rooted%20in%20the%20American%20dream%20%E2%80%93%20one%20day%20this%20nation%20will%20rise%20up%20and%20live%20up%20to%20its%20creed%2C%20%22We%20hold%20these%20truths%20to%20be%20self%20evident%3A%20that%20all%20men%20are%20created%20equal.&features=sentiment,keywords";
$post_args = array(
'version' => '2017-02-27',
'url' => 'https://davidwalsh.name/curl-post',
'features' => 'sentiment,keywords'
);
$headers = array(
'Content-Type:application/json'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, "my_username:my_password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
//curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
//curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_args));
$result = curl_exec($ch);
if ($result === FALSE) {
die('Send Error: ' . curl_error($ch));
}
curl_close($ch);
echo $result;
?>
I get this result:
{
"error": "unsupported media type",
"code": 415
}
What should be done?
I can't believe I was stuck here due to a blank space.
Replacing this:
$headers = array(
'Content-Type:application/json'
);
with
$headers = array(
'Content-Type: application/json'
);
worked. Note the blank space between : and application/json.
I have been working on building an Rest API for the hell of it and I have been testing it out as I go along by using curl from the command line which is very easy for CRUD
I can successfully make these call from the command line
curl -u username:pass -X GET http://api.mysite.com/pet/1
curl -d '{"dog":"tall"}' -u username:pass -X GET http://api.mysite.com/pet
curl -d '{"dog":"short"}' -u username:pass -X POST http://api.mysite.com/pet
curl -d '{"dog":"tall"}' -u username:pass -X PUT http://api.mysite.com/pet/1
The above calls are easy to make from the command line and work fine with my api, but now I want to use PHP to create the curl. As you can see, I pass data as a json string. I have read around and I think I can probably do the POST and include the POST fields, but I have not been able to find out how to pass http body data with GET. Everything I see says you must attached it to the url, but it doesn't look that way on the command line form. Any way, I would love it if someone could write the correct way to do these four operations in PHP here on one page. I would like to see the simplest way to do it with curl and php. I think I need to pass everything through the http body because my php api catching everything with php://input
PUT
$data = array('username'=>'dog','password'=>'tall');
$data_json = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data_json)));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
POST
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
GET
See #Dan H answer
DELETE
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
You can use this small library: https://github.com/ledfusion/php-rest-curl
Making a call is as simple as:
// GET
$result = RestCurl::get($URL, array('id' => 12345678));
// POST
$result = RestCurl::post($URL, array('name' => 'John'));
// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));
// DELETE
$result = RestCurl::delete($URL);
And for the $result variable:
$result['status'] is the HTTP response code
$result['data'] an array with the JSON response parsed
$result['header'] a string with the response headers
Hope it helps
For myself, I just encode it in the url and use $_GET on the destination page. Here's a line as an example.
$ch = curl_init();
$this->json->p->method = "whatever";
curl_setopt($ch, CURLOPT_URL, "http://" . $_SERVER['SERVER_NAME'] . $this->json->path . '?json=' . urlencode(json_encode($this->json->p)));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
EDIT: Adding the destination snippet... (EDIT 2 added more above at OPs request)
<?php
if(!isset($_GET['json']))
die("FAILURE");
$json = json_decode($_GET['json']);
$method = $json->method;
...
?>
I was Working with Elastic SQL plugin.
Query is done with GET method using cURL as below:
curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'
I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.
This code, works fine plus Basic Auth Header:
$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";
function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host.$uri);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($method == 'POST')
curl_setopt($ch, CURLOPT_POST, 1);
if ($auth)
curl_setopt($ch, CURLOPT_USERPWD, $auth);
if (strlen($data) > 0)
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
$resp = curl_exec($ch);
if(!$resp){
$resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
}
curl_close($ch);
return $resp;
}
$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT
set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);
I'm trying, without success, to get some results using Bing's Image search API without HTTP/Request2.php component (as used in the official examples).
I understand that the only two required parameters to make a very primitive call are q which is the query string and the subscription key. The key must be sent using headers. After looking around I found this very simple example to send headers with PHP:
$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats";
$aHTTP = array(
'Ocp-Apim-Subscription-Key' => 'xxxxxxx',
);
$context = stream_context_create($aHTTP);
$contents = file_get_contents($sURL, false, $context);
echo $contents;
But it does not output anything. Would you kindly help me with a very basic example of use of Bing's API?
SOLVED
Thanks to Vadim's hint I changed the way headers are sent and now output is a Json encoded result. (Remember to add your API subscription key.)
$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sURL);
curl_setopt($ch, CURLOPT_TIMEOUT, '1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: multipart/form-data',
'Ocp-Apim-Subscription-Key: xxxxx'
));
$content = curl_exec($ch);
echo $content;
Just another tip. The syntax of query filters and other parameters change form version to version. For example the following work correctly in version 5.0:
To search only for JPEG images of cats and get 30 results use:
q=cats&encodingFormat='jpeg'&count=30
To search only for 'portrait' aspect images with size between 200x200 and 500x500 use:
q=cats&aspect=Tall&size=Medium
Try using cURL
$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats";
$key = "xxxxxxx";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sURL);
curl_setopt($ch, CURLOPT_TIMEOUT, '1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 'ocp-apim-subscription-key:$key');
$content = curl_exec($ch);
echo $content;
Here is my working code..
Replace ******** with your bing subscription key.
$sURL = "https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=microsoft-surface&count=6&mkt=en-US";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: multipart/form-data',
'Ocp-Apim-Subscription-Key: *******************'
));
$contents = curl_exec($ch);
$myContents = json_decode($contents);
if(count($myContents->value) > 0) {
foreach ($myContents->value as $imageContent) {
echo '<pre/>';
print_r($imageContent);
}
}
Hi I am trying to post data Using CURL in PHP to diigo bookmarking, I have tried through API, When i executing file i got HTTP basic authentication here is my code
require_once('libs/diigo.class.php');
$diggo = new DiigoAPI("username","password");
$book = $diggo->getBookmarks();
$diggo->saveBookmarks("http://www.example.com");
public function saveBookmarks($url)
{
$attachment = array ("url" => $url, "title" => "SEnthil" , "shared" => "yes" );
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://secure.diigo.com/api/v2/bookmarks');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //to suppress the curl output
$result = curl_exec($ch);
echo $result;
curl_close ($ch);
}
Your curl doesn't have basic HTTP authentication set. You should set it up this way:
curl_setopt($curl, CURLOPT_USERPWD, $user_here . ":" . $password_here );
And the way you're doing it now the saveBookmarks function doesn't require the Diigo Class at all.
