POST call does not work correctly - php

I am currently working on a project and trying to do a POST call. The API documentation says the following
POST https://jawbone.com/nudge/api/v.1.1/users/#me/mood HTTP/1.1
Host: jawbone.com
Content-Type: application/x-www-form-urlencoded
title=MoodTest&sub_type=2
My code is:
$url = "http://jawbone.com/nudge/api/v.1.1/users/#me/mood";
$data = array('title' => 'moodTest', 'sub_type' => 2);
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded",
'method' => 'POST',
'content' => http_build_query($data)
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
title and sub_type are needed for changing the specific data.
I get the following error:
Warning: file_get_contents(http://...#me/mood): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in C:\wamp\www\main.php on line 53
Call Stack

2 0.9006 268584 postMood( ) ..\main.php:15
3 0.9007 271680 file_get_contents ( ) ..\main.php:53
What am I doing wrong?

You're issue seems to be that you are not authenticated.
If you open this request:
https://jawbone.com/nudge/api/v.1.1/users/#me/mood?title=asd&sub_type=2
on your browser, you will see the details of the error. If you check the headers in the response, you see that the status code is "404 Not Found".
I would suggest you to check the documentation of the API about how to authenticate or maybe switch to a supported API version (as the message of the response is "Unsupported API version 1.1, unless called with an OAuth header").

use javascript:
function getJson() {
var xhr = new XMLHttpRequest();
xhr.open("get", "https://jawbone.com/nudge/api/v.1.1/users/#me/mood", true);
xhr.onload = function(){
var response = JSON.parse(xhr.responseText);
}
xhr.send(null);
}

The best way in php to POST is to use curl (http://php.net/manual/ru/function.curl-exec.php)
so in your case you can use example (http://php.net/manual/ru/function.curl-exec.php#98628) :
function curl_post($url, array $post = NULL, array $options = array())
{
$defaults = array(
CURLOPT_POST => 1,
CURLOPT_HEADER => 0,
CURLOPT_URL => $url,
CURLOPT_FRESH_CONNECT => 1,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FORBID_REUSE => 1,
CURLOPT_TIMEOUT => 4,
CURLOPT_POSTFIELDS => http_build_query($post)
);
$ch = curl_init();
curl_setopt_array($ch, ($options + $defaults));
if( ! $result = curl_exec($ch))
{
trigger_error(curl_error($ch));
}
curl_close($ch);
return $result;
}
$url = "http://jawbone.com/nudge/api/v.1.1/users/#me/mood";
$data = array('title' => 'moodTest', 'sub_type' => 2);
$result = curl_post($url, $data);

First time with PHP and an API - can you help me with a basic example?

I'm very new to PHP and API, and my company was asked for a job of incorporating API calls on a PHP website.
This is the info about the API that the client gave to us:
API Manual
General Notes:
API URL: https://www.somedomain.com/api/
apiKey: 123qwe456rty678yui
HTTP Verb: POST
Content-Type: application/x-www-form-urlencoded
1. {EMPLOYEES category}
POST /en/1001/cat/10
POST /en/1001/cat/10/page/[999]
Observations:
• the list returns 20 records
• to get the reamining records: /en/1001/cat/10/page/2; /en/1001/cat/10/page/3; ...
• the information is returned in JSON format
• all the requests should be made by the POST method and the api key should be sent on the request body
Input variables:
• apiKey => App key
Return parameters:
retCode = “error”
retCode = “ok”
(...)
2. {NEWS category}
POST /en/2002/cat/20
POST /en/2002/cat/20/page/[999]
Observations:
• the list returns 20 records
• to get the reamining records: /en/2002/cat/20/page/2; /en/2002/cat/20/page/3; ...
• the information is returned in JSON format
Input variables:
• apiKey => App key
Return parameters:
retCode = “error”
retCode = “ok”
(...)
And I've made a simple PHP script but I'm getting an empty return value:
<?php
//API URL: https://www.somedomain.com/api/
//This is to test the Employees category - /en/1001/cat/10
$curl = curl_init();
$apiKey = urlencode("123qwe456rty678yui");
//$apiKey = "123qwe456rty678yui";
//it doesn't matter if this variable is urlencoded or not, as the result is always empty...
curl_setopt_array($curl, array(
CURLOPT_URL => "https://www.somedomain.com/api/en/1001/cat/10",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_SSL_VERIFYPEER => "false",
CURLOPT_POSTFIELDS => "apiKey=$apiKey",
CURLOPT_HTTPHEADER => array(
"content-type: application/x-www-form-urlencoded"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo "Response: " . $response;
}
?>
Like I said, I'm very new to this, PHP and API's, and the client isn't very helpful.
Based on the Manual API I have, what I'm doing wrong? $response is always empty, it gives no error even if I enter a wrong API Key, and I don't even know if I'm calling this the correct way...
Thanks in advance!
Here is a function that should work from the manual: https://www.php.net/manual/en/function.curl-setopt-array.php#89850
<?php
function get_web_page($url, $curl_data )
{
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => "spider", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
CURLOPT_POST => 1, // i am sending post data
CURLOPT_POSTFIELDS => $curl_data, // this are my post vars
CURLOPT_SSL_VERIFYHOST => 0, // don't verify ssl
CURLOPT_SSL_VERIFYPEER => false, //
CURLOPT_VERBOSE => 1 //
);
$ch = curl_init($url);
curl_setopt_array($ch,$options);
$content = curl_exec($ch);
$err = curl_errno($ch);
$errmsg = curl_error($ch) ;
$header = curl_getinfo($ch);
curl_close($ch);
// $header['errno'] = $err;
// $header['errmsg'] = $errmsg;
// $header['content'] = $content;
return $header;
}
$curl_data = "var1=60&var2=test";
$url = "https://www.example.com";
$response = get_web_page($url,$curl_data);
print '<pre>';
print_r($response);
?>
You can also try the file_get_contents function to get this JSON data.
Something like this could do the job:
// API URL
$apiUrl = 'https://www.somedomain.com/api/en/2002/cat/20';
// Request options
$opts = [
"http" => [
'method' => 'POST',
'header' => [
'Content-Type: application/x-www-form-urlencoded',
'apiKey: 123qwe456rty678yui'
]
]
];
// Request context
$context = stream_context_create($opts);
// Get JSON
$json = file_get_contents($apiUrl, false, $context);
Try and see if you can adapt it.

doing a REST PUT in PHP

I hope my question will be understood, my english is a not so good.
I'm nearly new with PHP and I just discovered REST APIs: I'm trying to use a REST API from my PHP script. Docs for the API can be found here
My final goal is to get a single product from this webservice and update it by adding the wholesalePrices array.
I've already managed to perform a GET request using file_get_contents(), in order to get the product ID i want to update. Now I have such id but can't understand how to perform the PUT request: as far I can understand, there are mainly two ways to do REST calls in PHP: one with file_get_contents, another by using cURL.
Since I used file_get_contents for my GET request, I continued with this approach, but my code:
$wholesalePrices = json_encode($wholesalePrices);
$dataRAW = array(
"wholesalePrices" => $wholesalePrices
);
$dataToPut = http_build_query($dataRAW);
$context = [
'http' => [
'method' => 'PUT',
'header' => "Authorization: apikeystring\r\n" . "Content-Length: " . strlen($dataToPut) . "\r\n" . "Content-Type: application/json\r\n",
'content' => $dataToPut
]
];
$context = stream_context_create($context);
$url = "https://app.ecwid.com/api/v3/xxxxxxx/products/".urlencode($productId)."?token=".urlencode(myToken);
$result = file_get_contents ($url, false, $context);
returns a PHP warning:
Warning: file_get_contents(https://app.ecwid.com/api/v3/xxxxxxxxx/products/xxxxxxxxx?token=xxxxxxxxxxx): failed to open stream: HTTP request failed! HTTP/1.1 400 Wrong JSON format: A JSONObject text must begin with '{' at 1 [character 2 line 1] in upload.php on line 95
var_dumping $wholesalePrices just after the json_encode() results in
string '[{"quantity":1,"price":0},{"quantity":5,"price":6},{"quantity":25,"price":12},{"quantity":100,"price":25}]' (length=106)
where am I wrong?
ok, I tried using RamRaider approach and now my code is this
$data = json_encode(array('wholesalePrices' => $wholesalePrices)/*, JSON_FORCE_OBJECT*/);
$dataRAW = array(
"wholesalePrices" => $wholesalePrices
);
$dataToPut = $dataRAW;
$dataToPut = http_build_query($dataRAW);
$context = array('http' => array('method' => 'PUT',
'header' => "Authorization: apikeystring\r\nContent-Length: ".strlen($data)."\r\nContent-Type: application/json\r\n",
'content' => $data));
$context = stream_context_create($context);
$url = "https://app.ecwid.com/api/v3/".urlencode(MY_STORE_ID)."/products/".urlencode($productId)."?token=".urlencode(MY_TOKEN);
$result = file_get_contents ($url, false, $context);
But I obtain a HTTP request failed! HTTP/1.1 400 Field Product.wholesalePrices should be an array message.
If I comment the , JSON_FORCE_OBJECT instead, the HTTP message becomes 409 Conflict and it refers at the line with $result = file_get_contents ($url, false, $context); so perhaps I am on the right track, but how can I troubleshoot such error?
ok, done some mods: now - after the json_encode() - my dataToPut (which I put in "Content" in the HTTP request) var_dumps as following (WPPair is a class I specifically created to reproduce the format required):
object(stdClass)[3]
public 'wholesalePrices' =>
array (size=3)
1 =>
object(WPpair)[5]
public 'quantity' => int 5
public 'price' => int 6
2 =>
object(WPpair)[4]
public 'quantity' => int 25
public 'price' => int 12
3 =>
object(WPpair)[6]
public 'quantity' => int 100
public 'price' => int 25
so I think it has to be right for the api. But I still get a HTTP request failed! HTTP/1.1 400 Bad Request
Ok, finally I managed to form a (perhaps) right structure for my JSON, all the more so as Postman validates my dataToPut with an HTTP
200 OK
And my test record results updated.
This is the print_r() output on dataToPut after json_encode():
string
'{"id":56782231,"wholesalePrices":[{"quantity":5,"price":5.64},{"quantity":25,"price":5.28},{"quantity":100,"price":4.5}]}'
(length=121)
However, if I try to send the same JSON from my PHP page, I still get a
failed to open stream: HTTP request failed!
and in fact, my records still aren't updated.
Here's my code:
$dataToPut = $dataRAW;
$dataRAW = http_build_query($dataRAW);
$context = [
'http' => [
'method' => 'PUT',
'header' => "Authorization: apikeystring\r\n" . "Content-Length: ".sizeof($dataToPut)."\r\n" . "Content-Type: application/json\r\n",
'content' => $dataToPut
]
];
$context = stream_context_create($context);
$url = "https://app.ecwid.com/api/v3/xxxxxxx/products/".urlencode($productId)."?token=".urlencode(myToken);
$dataToPut = json_encode($dataToPut);
$result = file_get_contents($url, false, $context);
Where am I wrong this time?
After rewriting my code by using cURL instead of file_get_contents to connect to the API, I managed to get it to work.
Now the API call part looks like this:
$dataToPut = $dataRAW;
$dataRAW = http_build_query($dataRAW);
$context = [
'http' => [
'method' => 'PUT',
'header' => "Authorization: apikeystring\r\n" . "Content-Length: ".sizeof($dataToPut)."\r\n" . "Content-Type: application/json\r\n",
'content' => $dataToPut
]
];
$context = stream_context_create($context);
$url = "https://app.ecwid.com/api/v3/xxxxxxx/products/".urlencode($productId)."?token=".urlencode($myToken);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Host: app.ecwid.com','Content-Type: application/json;charset=utf-8','Cache-Control: no-cache'));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $dataToPut);
// Make the REST call, returning the result
$response = curl_exec($curl);
echo ($response."<br/>");
if (!$response) {
echo("Connection Failure: ".curl_error($curl));
die();
}
curl_close($curl);
Without seeing the documentation for their api I might be leading you astray but the error message does suggest that their api expects json data whereas you encode the data and then add to an array which seems back to front somehow.
$data = json_encode( array( 'wholesalePrices' => $wholesalePrices ), JSON_FORCE_OBJECT );
/* Perhaps this also is not required */
#$data = http_build_query( $data );
$context = array(
'http' => array(
'method' => 'PUT',
'header' => "Authorization: apikeystring\r\nContent-Length: " . strlen( $data ) . "\r\nContent-Type: application/json\r\n",
'content' => $data
)
);
$context = stream_context_create( $context );
$url = "https://app.ecwid.com/api/v3/7560546/products/".urlencode( $productId )."?token=".urlencode( myToken );
$result = file_get_contents( $url, false, $context );
Having had a quick look at the api documentation I found the following:
PUT https://app.ecwid.com/api/v3/{storeId}/products/{productId}?token={token}
Request body
A JSON object of type 'Product’ with the following fields:
wholesalePrices -> Array<WholesalePrice>
described as: "Sorted array of wholesale price tiers (quantity limit and price pairs)"
The given example request to update a product is:
PUT /api/v3/4870020/products/39766764?token=123456789abcd HTTP/1.1
Host: app.ecwid.com
Content-Type: application/json;charset=utf-8
Cache-Control: no-cache
{
"compareToPrice": 24.99,
"categoryIds": [
9691094
]
}
So using test data
$wholesalePrices=array(
array('quantity'=>10,'price'=>1000),
array('quantity'=>2,'price'=>43),
array('quantity'=>43,'price'=>34),
array('quantity'=>7,'price'=>5),
array('quantity'=>9,'price'=>63),
);
$data = json_encode( array( 'wholesalePrices' => $wholesalePrices ) );
echo '<pre>',$data,'</pre>';
Gives data in the format:
{
"wholesalePrices":[
{"quantity":10,"price":1000},
{"quantity":2,"price":43},
{"quantity":43,"price":34},
{"quantity":7,"price":5},
{"quantity":9,"price":63}
]
}

Google Short URL API: Forbidden

I have what I think is correctly written code yet whenever I try and call it I'm getting permission denied from Google.
file_get_contents(https://www.googleapis.com/urlshortener/v1/url): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden
This isn't a rate limit or anything as I currently have zero ever used...
I would have thought this is due to an incorrect API key but I've tried resetting it a number of times. There isn't some downtime while the API is first applied is there?
Or am I missing a header setting or something else just as small?
public function getShortUrl()
{
$longUrl = "http://example.com/";
$apiKey = "MY REAL KEY IS HERE";
$opts = array(
'http' =>
array(
'method' => 'POST',
'header' => "Content-type: application/json",
'content' => json_encode(array(
'longUrl' => $longUrl,
'key' => $apiKey
))
)
);
$context = stream_context_create($opts);
$result = file_get_contents("https://www.googleapis.com/urlshortener/v1/url", false, $context);
//decode the returned JSON object
return json_decode($result, true);
}
It seems I need to manually specify the key in the URL
$result = file_get_contents("https://www.googleapis.com/urlshortener/v1/url?key=" . $apiKey, false, $context);
This now works. There must be something funny with how the API inspects POST for the key (or lack of doing so).
Edit: For anyone in the future this is my complete function
public static function getShortUrl($link = "http://example.com")
{
define("API_BASE_URL", "https://www.googleapis.com/urlshortener/v1/url?");
define("API_KEY", "PUT YOUR KEY HERE");
// Used for file_get_contents
$fileOpts = array(
'key' => API_KEY,
'fields' => 'id' // We want ONLY the short URL
);
// Used for stream_context_create
$streamOpts = array(
'http' =>
array(
'method' => 'POST',
'header' => [
"Content-type: application/json",
],
'content' => json_encode(array(
'longUrl' => $link,
))
)
);
$context = stream_context_create($streamOpts);
$result = file_get_contents(API_BASE_URL . http_build_query($fileOpts), false, $context);
return json_decode($result, false)->id;
}

header parameters post request php ( curl)

I' m trying to build a php script that post other webservice I'm using culr as you can see, the issue is in the API webserver docs ask me to send some header parameters, literally
"For each http call you will need to add the following header parameters:
APIuserID,
APIpassword and
ResponseType"
so my question is how can I add custom parameters to my header request?. thanks
<?php
function curl_post($url, array $post = NULL, array $options = array())
{
$defaults = array(
CURLOPT_POST => 1,
CURLOPT_HEADER => 0,
CURLOPT_URL => $url,
CURLOPT_FRESH_CONNECT => 1,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FORBID_REUSE => 1,
CURLOPT_TIMEOUT => 4,
CURLOPT_SSL_VERIFYHOST=>0,
CURLOPT_POSTFIELDS => http_build_query($post)
);
$ch = curl_init();
curl_setopt_array($ch, ($options + $defaults));
if( ! $result = curl_exec($ch))
{
trigger_error(curl_error($ch));
}
curl_close($ch);
return $result;
}
$result=curl_post('https://www.serverPath/serverAPI',array('a'=>'a','b'=>'b'));
echo $result;
?>
Have you tried by just adding those parameters to the httpheader?
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array(
"Content-Type: text/xml",
"APIuserID: $id",
"APIpassword: $password",
"Content-length: ".strlen($data)
));
Additionally you can use: http://php.net/manual/en/soapheader.soapheader.php

posting json data with curl and failing

I have this function here:
public static function call($action, array $args)
{
$post_args = array(
'action' => $action,
'args' => $args
);
$stream = json_encode($post_args);
$headers = array(
'Content-type: application/json',
'Accept: application/json',
'Expect:'
);
$userpwd = self::$_user.':'.sha1(sha1(self::$_pass));
$ch = curl_init();
$args = array(
CURLOPT_URL => self::$_url,
CURLOPT_FOLLOWLOCATION => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_POST => TRUE,
CURLOPT_POSTFIELDS => $stream,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_USERPWD => $userpwd
);
curl_setopt_array($ch, $args);
$res = curl_exec($ch);
$data = json_decode($res, true);
if (isset($data) === TRUE
&& empty($data) === FALSE
) {
$res = $data;
}
return $res;
}//end call()
and at the URL where I'm posting, I'm just doing:
echo file_get_contents('php://input');
but getting nothing, even though I do post data. What could be the problem? I'm at a dead end.
Also, why do I need CURLOPT_FOLLOWLOCATION set to TRUE when I'm just posting to a simple virtual host URL on my local machine, not doing any redirects.
EDIT:
tried redoing it with fopen like so:
public static function call($action, array $args)
{
$post_args = array(
'action' => $action,
'args' => $args
);
$stream = json_encode($post_args);
$userpwd = self::$_user.':'.sha1(sha1(self::$_pass));
$opts = array(
'http' => array(
'method' => 'POST',
'header' => array(
"Authorization: Basic ".base64_encode($userpwd),
"Content-type: application/json"
),
'content' => $stream
)
);
$context = stream_context_create($opts);
$res = '';
$fp = fopen(self::$_url, 'r', false, $context);
if($fp){
while (!feof($fp)){
$res .= fread($fp, 128);
}
}
return $res;
}//end call()
no success. The connection works with curl and with fopen, since I pass the status along with result (which is just the php://input stream). Any ideas?
Can you be sure about that curl_exec function ends successfully. Also, why don't you use fopen for this purpose. I have written a JSON RPC client and server. I'm sending requests with fopen, and it works perfect.
$httpRequestOptions =
array(
'http'=>array(
'method'=>'POST',
'header'=>'Content-type: application/json',
'content'=>$requestJSON
)
);
$context = stream_context_create($httpRequestOptions);
// send request
if($fileHandler = #fopen($serverURL, 'r', false, $context)){
I'm not writing the rest. You can use this code I have written.
Found out the problem.
I was calling http://localhost/api, since I thought that it would load the index.php automatically, and then I was going to change the default file name for the folder.
The problem was that I didn't add index.php at the end - I should've called http://localhost/api/index.php.
This way it worked with cURL and with fopen.
Any ideas how to call the API without revealing the filename?
