I'm trying to use the Udemy API with the correct answer from this Stackoverflow's post: curl request in udemy api is not working
header('Content-Type: application/json');
$url = "https://www.udemy.com/api-2.0/courses";
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-Udemy-Client-Id: xxx','X-Udemy-Client-Secret: xxx',"Authorization: base64 encoded value of client-id:client-secret","Accept: application/json, text/plain, */*"));
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
$result=curl_exec($ch);
echo curl_getinfo($ch, CURLINFO_HEADER_OUT);
echo curl_getinfo($ch,CURLINFO_HTTP_CODE);
// Closing
curl_close($ch);
// Will dump a beauty json :3
echo $result = json_decode($result,true);
I have added my own client ID and secret ID and tested them on the Udemy sites getting a status 200.
The error I get from the code above is: 403 Notice Array to string conversion.
Can anyone sees what am I missing?
echo $result = json_decode($result,true);
json_decode() turns the response (string containing a JSON) into an associative array.
You then pass the array to echo and this raises the error.
The fix:
echo $result; // `$result` is still a string (the response)
Then if you need to access the response as an associative array
$result = json_decode($result,true);

I have a php curl script that returns the results of a get the run as a command from another process. The code is:
<?php
$arr = getopt("f:");
$url = $arr['f'];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo curl_error($ch);
} else {
echo $result;
}
curl_close($ch);
?>
When I do a api get request for a specific url with curl that gives a 400 error, curl_error($ch) is "The requested URL returned error: 400 Bad Request"
When I run the same request in postman, I get a json reply such as: {"result_ok":false,"code":400,"message":"Invalid Email: xxxxxxxxxx#ail.com (POST)"}.
How can I get the json returned in the curl request? If I echo the $result when there is an error condition, it is null.
From CURLOPT_FAILONERROR explained:
fail the request if the HTTP code returned is equal to or larger than 400. The default action would be to return the page normally, ignoring that code.
CURLOPT_FAILONERROR is false by default so either remove it or set it:
curl_setopt($ch, CURLOPT_FAILONERROR, false);
I wanted to try to get data from a JSON string which is loaded from another page. I currently have used Curl to get the data from the webpage but I can't acces the data in it.
I've already tried:
var_dump(json_decode($result->version, true));
var_dump(json_decode($result[3][0]["date"], true));
But this does't seem to work as it always returns NULL
$url="https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201";
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
First decode the JSON, then get the properties you want. Like this:
$yourObject = json_decode($result);
var_dump($youObject->version);
this is working for me.
<?php
$url = "https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201";
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL, $url);
// Execute
$result = curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
$data = json_decode($result);
//echo $data->data[0]['date'];
echo "<pre>";
print_r($data->data[0]->date);
}
?>
if you want to get date of all index then try this in loop.
Firstly if your using GET there is no need to use CURL,
$result = file_get_contents(https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201);
Will work just as well without any of the overhead. I suspect that your CURL isn't returning the page content so using file_get_contents() will fix it.
I'm trying to write a request with curl. I want to get the distance between two points. Therefore I'm getting the data of those points from my db to build the string. The final string looks like this when I echo it.
http://maps.googleapis.com/maps/api/distancematrix/json?origins=40215+Düsseldorf+Königsallee 59&destinations=40215+Düsseldorf&sensor=false
I also tried it with https instead of http but the result was the same.
As you can see, it returns a perfectly fine JSON-Response, but when I do this afterwards, I always get an error.
public function request($signedUrl) {
$ch = curl_init($signedUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
$this->response = json_decode($data);
}
The $signedUrl is the requestUrl.
The error from Google I get, when I var_dump($data) is
400. That’s an error.
Your client has issued a malformed or illegal request. That’s all we know. "
When I var_dump the response, it just gives me null.
What could be the problem here and how could I fix it? I also tried to read it in with file_get_contents but without success
Works [Tested] . You got a bad request since the URL was not encoded.
<?php
$urlx='http://maps.googleapis.com/maps/api/distancematrix/json?origins=40215+D%C3%BCsseldor%20%E2%80%8Bf+K%C3%B6nigsallee59&destinations=40215+D%C3%BCsseldorf&sensor=false';
$ch = curl_init($urlx);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);
var_dump(($data));
Hi I'm a little new at CURL, but I'm trying to request some json data and then parse the results. I am having success with retrieving the data, but I can't handle the response. Here's the code
function bitBucketCurl($url)
{
global $bitPassword;
global $bitUsername;
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$bitUsername:$bitPassword");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
$commitinfo = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
return $commitinfo;
}
$json = bitBucketCurl($url);
echo $json; // This seems to work in that, when I load the page, I can see the json data
//turn json data into an array - this is what does not seem to be working
$obj_a = json_decode($json, true);
print_r ($obj_a); //the result is simply a 1 rather than the array I would expect
The basic problem is the json data shows up when I echo $json but when I try to turn that data into an array it doesn't work. When I print the array, I just get a '1'.
I got the required result by adding the following line:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
I have a frontend code
$ch = curl_init();
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
curl_setopt($ch, CURLOPT_URL, $url);
//make the request
$responseJSON = curl_exec($ch);
$response_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($response_status == 200) { // success
// remove any "problematic" characters from the json string and then decode
if (debug) {
echo "----finish API of getAPI inside basic_function with status==200---";
echo "<br>";
echo "-------the json response is-------" ; //.$responseJSON;
var_dump($responseJSON);
//print_r($responseJSON);
echo "<br>";
}
return json_decode( preg_replace( '/[\x00-\x1F\x80-\xFF]/', '', $responseJSON ) );
}
and I have a backend code which executed when cURL fired its operation with its URL. The backend code would therefore activated. So, I know cURL is operating.
$output=array (
'status'=>'OK',
'data'=>'12345'
)
$output=json_encode($output)
echo $output;
and $output shown on browser as {"status":"OK","data":"12345"}
However, I gone back to the frontend code and did echo $responseJSON, I got nothing. I thought the output of {"status":"OK","data":"12345"} would gone to the $responseJSON. any idea?
Here's output on Browser, something is very odd! the response_status got 200 which is success even before the parsing of API by the backend code. I expect status =200 and json response after the {"status":"OK","data":"12345"}
=========================================================================================
inside the get API of the basic functions
-------url of cURL is -----http://localhost/test/api/session/login/?device_duid=website&UserName=joe&Password=1234&Submit=Submit
----finish API of getAPI inside basic_function with status==200---
-------the json response is-------string(1153)
"************inside Backend API.php******************

Have you tried with curl_setopt($ch, CURLOPT_TIMEOUT, 10); commented?
See what happends if you comment that line.
Also try with the a basic code, if that works, smthing you added later is wrong:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, false);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
Try var_dump($responseJSON)
If it returns false try
curl_error ( $ch )
Returns a clear text error message for the last cURL operation.
Are you sure your $url is correct?
