How to send JSON and retrieve it using cURL? - php

This link = http://localhost/api_v2/url?key=***
will return this list of JSON :
I've already tested by :
Navigate to http://localhost/api_v2/url?key=*** through a browser
And make a curl request via command line $ curl http://localhost/api_v2/url?key=***
either way will give return the JSON, and give me the same result.
Well, what I can tell by that is my $array is storing something in it.
Even if I did dd($array) - I still get the same result.
Here is what I've
Here is how I establish my JSON
public function index_2(){
$file_name = 'inventory.csv';
$file_path = 'C:\\QuickBooks\\'.$file_name;
$csv= file_get_contents($file_path);
$utf8_csv = utf8_encode($csv);
$array = array_map("str_getcsv", explode("\n", $utf8_csv));
return Response::json($array);
}
Here is how I make a cURL request and trying to retrieve that JSON
<?php
$ch = curl_init("http://localhost/api_v2/url?key=***");
curl_setopt($ch, CURLOPT_USERPWD, "admin:*****");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$body = curl_exec($ch);
curl_close($ch);
$json_decode = json_decode($array, TRUE);
I keep getting complaint that $array variable is not define, but in fact I did define and send it over like this return Response::json($array); .
I am not sure what I did wrong here.

Spot the difference:
$body = curl_exec($ch);
^^^^^
$json_decode = json_decode($array, TRUE);
^^^^^^

How to use json to pass data from a php file to another php file

As mentioned earlier , i am working on the local server as of now in xampp. I have created 2 files index.php and test.php. What i want to achieve is that , index.php will send json data to test.php , with the json data received , the test.php is able to use that json data to turn the statistics into graph.
I am working with the first step , but however , nothing seems to display on my test.php when i tried to do a var_dump($data) , and what i get is NULL. Tried alot of solutions online but none to seems to fix it. I am relatively new to this , so really thanks and appreciate of your help. First php is index.php , second php is test.php.
Do i require a live server as of now in order to see the results in test.php or local server unable to display the result?
<?php
$array = array();
$product = array();
$product[0]['id_product'] = 'A01';
$product[0]['name_product'] = 'Sandal';
$product[0]['price_product'] = '500';
$product[1]['id_product'] = 'A02';
$product[1]['name_product'] = 'Shoes';
$product[1]['price_product'] = '2500';
$array['id'] = '123';
$array['note'] = 'this is my short example';
$array['data'] = $product;
$data = json_encode($array);
$ch = curl_init('http://localhost:8080/practice3/test.php');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, count($data));
$result = curl_exec($ch);
var_dump($result);
?>

<?php
$fp = fopen('php://input', 'r');
$raw = stream_get_contents($fp);
$data = json_decode($raw,true);
echo "hello";
echo $data['id'];
echo $data['note'];
foreach ($data['data'] as $key) {
echo 'id_product : '.$key['id_product'].'<br/>';

Get location from a stream url in PHP

I'm trying to get the redirect url from a stream using php.
Here's the code I have right now:
<?php
$stream = 'https://api.soundcloud.com/tracks/178525956/stream?client_id=XXXXXX';
$ch = curl_init($stream);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$url = curl_exec($ch);
echo $url;
curl_close($ch);
?>
Which outputs as a string:
{"status":"302 - Found","location":"THE_URL_I_WANT"}
So how ould I go about getting the url I want as a variable?
Thanks
It's simple use json_decode
$data = json_decode($url);
$your_url = $data->location;
How about
$data = json_decode($url);
$location = $data["location"];

POST url with Curl PHP

I have a thank you page with URL that contains variables :
http://vieillemethodecorpsneuf.com/confirmation-achat-1a/?item=1&cbreceipt=VM6JQ6VE&time=1429212702&cbpop=C123FA24&cbaffi=twitpalace&cname=Roberto+Laplante&cemail=roberto%40gmail.com&ccountry=FR&czip=000
I have this GET function to catch the variables :
<?php
$clickbank_name = (isset($_GET['cname'])) ? $_GET['cname'] : '';
$clickbank_email = (isset($_GET['cemail'])) ? $_GET['cemail'] : '';
$clickbank_country = (isset($_GET['ccountry'])) ? $_GET['ccountry'] : '';
$clickbank_zip = (isset($_GET['czip'])) ? $_GET['czip'] : '';
$clickbank_aff = (isset($_GET['cbaffi'])) ? $_GET['cbaffi'] : '';
?>
Now I need to use curl PHP to send the data to that Zapier URL (but with the variables attached to it so it will give me) :
https://zapier.com/hooks/catch/bheq6y/?tag=client&cbaffi=twitpalace&cname=Roberto+Laplante&cemail=roberto%40gmail.com&ccountry=FR&czip=000
ps. I have added a manual tag to the URL
What would be the PHP Curl code to make this work? Need to be behind the scene operation.
I'll give it a shot.
$get_fields = ['tag' => 'client'];
if (isset($_GET['cname'])) $get_fields['cname'] = $_GET['cname'];
if (isset($_GET['cemail'])) $get_fields['cemail'] = $_GET['cemail'];
if (isset($_GET['ccountry'])) $get_fields['ccountry'] = $_GET['ccountry'];
if (isset($_GET['czip'])) $get_fields['czip'] = $_GET['czip'];
if (isset($_GET['cbaffi'])) $get_fields['cbaffi'] = $_GET['cbaffi'];
$encoded = '';
foreach($get_fields as $name => $value){
$encoded .= urlencode($name).'='.urlencode($value).'&';
}
$url = 'https://zapier.com/hooks/catch/bheq6y/?'.rtrim($encoded,'&');
// simple get curl
$output = file_get_contents($url);
// or if you want more control over the request
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $url,
));
$output = curl_exec($curl);
curl_close($curl);
In this example, we are posting data in parameters to another curl.php page and in curl.php,
i wrote some code to get executed whenever curl.php get called and the result will be sent back to page from where curl.php got a request.
Mechanism : This example is made in PHP using Curl.
First Step : Create curl.php file. That file will be called by another php file by using curl mechanism.
So in curl.php we will get some parameters. We get parameters and do some functionalities. After that when we desire output,
we just encode with json using json_encode() and simple echo.
$post = $_POST;
echo json_encode($post);
Note : index.php will get the data in json format because we are sending back data in json format to index.php
Second Step : we have to create an index.php file. Where we write a logic for executiing a curl with some parameters and then call curl.php and get result from curl.php
$url = 'http://localhost/curl_demo/curl.php'; // This is my targeted file(curl.php) that i want to execute when curl executed
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'id=1&name=sanjay'); // pass parameters to curl.php
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
$resArr = json_decode($response, true);
curl_close($ch);
print_r($resArr);
Note: The data that we get after curl executed successfully, we will get it in json format. That means we have to decode it using json_decode() in php.

Getting JSON Object by calling a URL with parameters in PHP

I'm trying to get json data by calling moodle url:
https://<moodledomain>/login/token.php?username=test1&password=Test1&service=moodle_mobile_app
the response format of moodle system is like this:
{"token":"a2063623aa3244a19101e28644ad3004"}
The result I tried to process with PHP:
if ( isset($_POST['username']) && isset($_POST['password']) ){
// test1 Test1
// request for a 'token' via moodle url
$json_url = "https://<moodledomain>/login/token.php?username=".$_POST['username']."&password=".$_POST['password']."&service=moodle_mobile_app";
$obj = json_decode($json_url);
print $obj->{'token'}; // should print the value of 'token'
} else {
echo "Username or Password was wrong, please try again!";
}
Result is: undefined
Now the question:
How can I process the json response format of moodle system? Any idea would be great.
[UPDATE]:
I have used another approach via curl and changed in php.ini following lines: *extension=php_openssl.dll*, *allow_url_include = On*, but now there is an error: Notice: Trying to get property of non-object. Here is the updated code:
function curl($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$moodle = "https://<moodledomain>/moodle/login/token.php?username=".$_POST['username']."&password=".$_POST['password']."&service=moodle_mobile_app";
$result = curl($moodle);
echo $result->{"token"}; // print the value of 'token'
Can anyone advise me?
json_decode() expects a string, not a URL. You're trying to decode that url (and json_decode() will NOT do an http request to fetch the url's contents for you).
You have to fetch the json data yourself:
$json = file_get_contents('http://...'); // this WILL do an http request for you
$data = json_decode($json);
echo $data->{'token'};

Decoding JSON after sending using PHP cUrl

I've researched everywhere and cannot figure this out.
I am writing a test cUrl request to test my REST service:
// initialize curl handler
$ch = curl_init();
$data = array(
"products" => array ("product1"=>"abc","product2"=>"pass"));
$data = json_encode($data);
$postArgs = 'order=new&data=' . $data;
// set curl options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postArgs);
curl_setopt($ch, CURLOPT_URL, 'http://localhost/store/rest.php');
// execute curl
curl_exec($ch);
This works fine and the request is accepted by my service and $_Post is populated as required, with two variables, order and data. Data has the encoded JSON object. And when I print out $_Post['data'] it shows:
{"products":{"product1":"abc","product2":"pass"}}
Which is exactly what is expected and identical to what was sent in.
When I try to decode this, json_decode() returns nothing!
If I create a new string and manually type that string, json_decode() works fine!
I've tried:
strip_tags() to remove any tags that might have been added in the http post
utf8_encode() to encode the string to the required utf 8
addslashes() to add slashes before the quotes
Nothing works.
Any ideas why json_decode() is not working after a string is received from an http post message?
Below is the relevant part of my processing of the request for reference:
public static function processRequest($requestArrays) {
// get our verb
$request_method = strtolower($requestArrays->server['REQUEST_METHOD']);
$return_obj = new RestRequest();
// we'll store our data here
$data = array();
switch ($request_method) {
case 'post':
$data = $requestArrays->post;
break;
}
// store the method
$return_obj->setMethod($request_method);
// set the raw data, so we can access it if needed (there may be
// other pieces to your requests)
$return_obj->setRequestVars($data);
if (isset($data['data'])) {
// translate the JSON to an Object for use however you want
//$decoded = json_decode(addslashes(utf8_encode($data['data'])));
//print_r(addslashes($data['data']));
//print_r($decoded);
$return_obj->setData(json_decode($data['data']));
}
return $return_obj;
}
Turns out that when JSON is sent by cURL inside the post parameters & quot; replaces the "as part of the message encoding. I'm not sure why the preg_replace() function I tried didn't work, but using html_entity_decode() removed the &quot and made the JSON decode-able.
old:
$return_obj->setData(json_decode($data['data']));
new:
$data = json_decode( urldecode( $data['data'] ), true );
$return_obj->setData($data);
try it im curious if it works.
