I can not consume a service from PHP - php

I am trying to consume a service that I exposed from a project that I have in c #, the problem is that when consuming the service from php I get the following error.
{"error":"unsupported_grant_type"}
Code:
function __construct() {
# data needs to be POSTed to the Play url as JSON.
# (some code from http://www.lornajane.net/posts/2011/posting-json-data-with-php-curl)
$data = array("grant_type" => "password", "username" => "Administrador", "password" => "xxxx");
$data_string = json_encode($data);
print_r($data_string);
$ch = curl_init('https://integraciones.intergrupo.com/rest/oauth/token');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/x-www-form-urlencoded')
);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
echo $result; // Outputs the JSON decoded data
}


You are sending a header 'Content-Type: application/x-www-form-urlencoded'.
With that you shouldn't json_encode $data, but just add the array to POSTFIELDS:
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
OR change the header to 'Content-Type: application/json'

Why CURLOPT_POSTFIELDS does not accept json_encode?

CURLOPT_POSTFIELDS does not accept json_encode, but if I directly write the json in the CURLOPT_POSTFIELDS if it is entered
This returns an error
{"error":"bad_request","reason":"Request body must be a JSON object"}
$bd = "fiscont_db_catalogo_cuentas";
$ch = curl_init();
$document ='{"docs":[{"key":"baz","name":"bazzel"},{"key":"bar","name":"barry"}]}';
$json = json_encode($document);
echo $json;
curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1:5984/'.$bd.'/_bulk_docs');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); /* or PUT */
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Accept: */*'
));
curl_setopt($ch, CURLOPT_USERPWD, 'root:addc1243c');
$response = curl_exec($ch);
echo $response;
curl_close($ch);
but this is returning :
[{"ok":true,"id":"8b3c672ffd4b8dcd7da313e9e9011243","rev":"1-f5f3f3e496c72307975a69c73fd53d42"},{"ok":true,"id":"8b3c672ffd4b8dcd7da313e9e9011c5a","rev":"1-8ad0e70d5e6edd474ec190eac2376bde"}]
$bd = "fiscont_db_catalogo_cuentas";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1:5984/'.$bd.'/_bulk_docs');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); /* or PUT */
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"docs\":[{\"key\":\"baz\",\"name\":\"bazzel\"},{\"key\":\"bar\",\"name\":\"barry\"}]}");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Accept: */*'
));
curl_setopt($ch, CURLOPT_USERPWD, 'root:addc1243c');
$response = curl_exec($ch);
echo $response;
curl_close($ch);

json_encode takes an array or an object as a parameter. In your example, you encode a JSON string to JSON which doesn't make sens.
If you replace your line by this:
$document =['docs' => [['key'=>'baz','name'=>'bazzel'],['key'=>'bar','name'=>'barry']];
It will correctly convert your PHP associative array to JSON.

Issue with PHP JSON encoding missing Object

I am creating a script that passes on some json formatted data. I'm having a issue encoding it correctly. Below is my code:
$data = array("email" => "theemail#email.com");
$data_string = json_encode(array('profiles' => $data));
$ch = curl_init('https://theurlisHere');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
echo $result;
I need my json to look like this:
"profile": [
{
"email": "theemail#email.com"
}
]
I can't figure out how to get the 'profile' object in to the array.
Thanks in advance.

You can use
json_encode(array('profile' => array($data)));

Zoho API V2 Update Record

I am trying to use the Zoho API Version 2 to do a simple record update in Leads. I am using PHP and CURL and my sample code for this call (to update a single field in the record) is as follows:-
$apiUrl = "https://www.zohoapis.com/crm/v2/Leads/" . {valid record id here};
$headers = array(
'Content-Type: application/json',
'Content-Length: ' . strlen($fields),
sprintf('Authorization: Zoho-oauthtoken %s', {valid auth token here})
);
$fields = json_encode([["data" => ["City" => "Egham"]]]);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
$result = curl_exec($ch);
curl_close($ch);
No matter how I format the JSON, I always get the following returned:
{"code":"INVALID_DATA","details": {"expected_data_type":"jsonobject"},"message":"body","status":"error"}
It is not a matter of invalid auth tokens etc because I have successfully used PHP and CURL with the Zoho API to read data and I decode the JSON returned successfully.
Please could somebody help with passing valid JSON data?

The above code constructs input JSON like this
[{"data":{"City":"Egham"}}]. This JSON is not valid as per the ZOHO CRM APIs(API help).
It should be like this {"data":[{"City":"Egham"}]}.
Change the code like this :
$apiUrl = "https://www.zohoapis.com/crm/v2/Leads/" . {valid record id here};
$fields = json_encode(array("data" => array(["City" => "Egham"])));
// *strlen must be called after defining the variable. So moved headers down to $fields*
$headers = array(
'Content-Type: application/json',
'Content-Length: ' . strlen($fields),
sprintf('Authorization: Zoho-oauthtoken %s', {valid auth token here})
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
$result = curl_exec($ch);
curl_close($ch);

You must escape the data into JSON format:
import json
response = requests.post(url, data=json.dumps(data), headers=headers)

curl POST error: The requested URL returned error: 413

I've looked around a bit and can't find a solution that solves my problem. I'm getting the following error: "The requested URL returned error: 413."
I'm posting some information via curl and PHP to a URL via HTTPS. I'm told that I have to pass the "Content-Length" along with my request since the destination is https and not http.
Here's the code I'm using:
$user = '11111111111111111';
$books = array(111);
$data = array("action" => "books-shared", "userID" => $user, "bookIDs" => $books);
$data_string = array('json'=>json_encode($data));
$target_url = 'https://www.test.com/test.php'; // fake URL of course
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$api = curl_exec($ch);
My strlen($data_string) command is returning a value of 5, which is much less than the actual length of the $data_string, which is much longer. I assume this is the problem unless someone thinks it might be being caused by something else.

Here's what I ended up with:
$user = '11111111111111111';
$books = array(111);
$data = array("action" => "books-shared", "userID" => $user, "bookIDs" => $books);
$data_string = array('json'=>json_encode($data));
$target_url = 'https://www.test.com/test.php'; // fake URL of course
$ch = curl_init();
if (!$ch) {
die("Couldn't initialize a cURL handle");
}
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_URL, $target_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
$api = curl_exec($ch);
No SSL or size errors and it seems to work fine.

POST JSON with PHP cURL

I have the following php code
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, $this->_agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->_headers);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_VERBOSE, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
curl_setopt($ch, CURLOPT_POST, 1);
But I don't understand why is not working . The API that I'm posting the JSON to says that the parameters were not received . Is there anything wrong in my code ? I think the whole trick is on the JSON parameters... I'm not sure how to send them as I couldn't see any "nave->value" pair with the http analyzer as it usually appears in simple forms ... just that JSON code without any "name".

You can try as follows.
Basically if we have a array of data then it should be json encoded using php json_encode. And you should also add content-type in header which can be defined in curl as curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$data = array("country"=>"US","states"=>array("MHASASAS"=>"MH","XYZABABA"=>"XYZ"));
$postdata = json_encode($data);
$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);

you can use this and replace with
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}');
use this
$Parameters = array(
'MerchantCode' => $MerchantCode,
'PriceValue' => $amount,
'ReturnUrl' => $callback,
'InvoiceNumber' => $resnum,
);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($Parameters));

If:you use post method,you should know that:
CURLOPT_POST TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.
#see http://php.net/manual/en/function.curl-setopt.php
So:you can do like this:
$ar_form = array('name'=>'PHPJungle','age'=>66,'gender'=>'male');
$poststr = http_build_query($ar_form ); # important
$options[CURLOPT_HTTPGET] = false;
$options[CURLOPT_POST] = true;
$options[CURLOPT_POSTFIELDS] = $poststr ; //default type:application/x-www-from-urlencoded
curl_setopt_array ( $ch, $options );
# #todo your other codes
This is my class I have used for a long time.The class is based on PHP cURL.
It supports GET/POST，HTTP/HTTPS.
#see https://github.com/phpjungle/iHttp/

You can post a json data with curl like so:
Using Command Prompt:
curl -X POST -H "Content-Type: application/json" -d '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}' $url
Using PHP:
$data = array("folderId"=>"1","parameters"=>array("amount"=>3,"ascending"=>false,"offset"=>0,"sort"=>"date"));
$postdata = json_encode($data);
OR
$postdata = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);

You haven't set the content type, so the post data is being sent as form data. Try setting the content type to application/json.
If that doesn't work, try wrapping the json string with an array.

$link = "http://test.domain/myquery";
$json = '{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}';
$postdata = json_decode($json);
echo openurl($link, $postdata);
This works as json decode converts a json string into array.
function openurl($url, $postvars = "") {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, '3');
$content = trim(curl_exec($ch));
curl_close($ch);
return $content;
}

if your API endpoint using body for send request using json data may be you can use Guzzle the doc is here doc.
use GuzzleHttp\Client;
$client = new Client();
$request = $this->client->post($url,array(
'content-type' => 'application/json'
),array());
$request->setBody($json_data);
$response = $request->send();
return $response;
hope this work.

You can do it make by steps:
$data = array(
'folderId'=>"1","parameters"=>array(
"amount"=>"3","ascending"=>false,"offset"=>0,"sort"=>"date"
)
);
$data_string = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
I don't know if you need the header. I think that by default it is already application/x-www-form-urlencode
If it doesn't work, try changing the $data values in array. Think it helps. :)

I'm not sure, that this is the solution but this works for me when posting json, change the json from
'{"folderId":"1","parameters":{"amount":3,"ascending":false,"offset":0,"sort":"date"}}'
to
"{'folderId':'1','parameters':{'amount':3,'ascending':false,'offset':0,'sort':'date'}}"
The only change i made was the double quotes are now on the outside, that works for me but I'm obviously posting to a different server
Only other help I could offer is to download a network debugging tool such as Fiddler or Charles proxy and monitor the requests sent/received, it could be a case that something else is wrong in your code.
Hope i helped :)

first of all
please check the curl http status code
$http_code= curl_get_info($exec_res,CURL_HTTP_CODE);
then modify this request header set with post header API server add a recorder to log those request info.
