I have two scripts:
First to send:
$url = "http://localhost/curl2.php";
$data = array('email' => 'test#example.com');
$addr = $url . '?' . http_build_query($data);
$ch = curl_init($addr);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_exec($ch);
And second to receive:
if($_SERVER['REQUEST_METHOD'] == "PUT") {
$data = array();
$incoming = file_get_contents("php://input");
parse_str($incoming, $data);
echo "Address: " . filter_var($data["email"], FILTER_VALIDATE_EMAIL);
}
But variable $incoming is empty. How can I do it? Maybe it has something to do with PUT, but I must use PUT.
PUT is not GET. Use the URL without a query string and add the data to CURLOPT_POSTFIELDS:
$url = "http://localhost/curl2.php";
$data = array('email' => 'test#example.com');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_exec($ch);

I am struggling using Binance's REST API. I have managed to get working GET request via query string such as pinging the server, ticker information, etc. My challenge now is performing POST request via query string using cURL. I have been scraping code from various places and referring back to the API to get pieces to work but I am unsure as to why I am getting this error returned from the result... {"code":-1102,"msg":"Mandatory parameter 'signature' was not sent, was empty/null, or malformed."}
(ERROR SHOWN ON WEBPAGE). I echo out the signature and its a load of gibberish so I would believe that the hash_hmac performed at the top would be working, but honestly I got pretty lucky making the GET request work. Does anyone have any suggestions as to why this would be broken? Thanks!
$apikey = "MYKEY";
$apisecret = "MYSECRET";
$timestamp = time()*1000; //get current timestamp in milliseconds
$signature = hash_hmac('sha256', "TRXBTC&type=market&side=buy&quantity=100.00&recvWindow=10000000000000000×tamp=".$timestamp, $apisecret);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.binance.com/api/v3/order/test");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, "symbol=TRXBTC&type=market&side=buy&quantity=100.00&recvWindow=10000000000000000×tamp=".$timestamp);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","X-MBX-APIKEY: ".$apikey,"signature: ".$signature));
$response = curl_exec($ch);
curl_close($ch);
echo $response;
As per their API docs:
SIGNED endpoints require an additional parameter, signature, to be sent in the query string or request body.
You are sending the signature via neither of these methods and are instead sending it through the header.
Change this:
curl_setopt($ch, CURLOPT_POSTFIELDS, "symbol=TRXBTC&type=market&side=buy&quantity=100.00&recvWindow=10000000000000000×tamp=".$timestamp);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","X-MBX-APIKEY: ".$apikey,"signature: ".$signature));
To this:
curl_setopt($ch, CURLOPT_POSTFIELDS, "symbol=TRXBTC&type=market&side=buy&quantity=100.00&recvWindow=10000000000000000×tamp=" . $timestamp . "&signature=" . $signature);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","X-MBX-APIKEY: ".$apikey));
<?php
$secret = "F................";
$key = "D.................";
$s_time = "timestamp=".time()*1000;
$sign=hash_hmac('SHA256', $s_time, $secret);
$url = "https://api.binance.com/api/v3/account?".$s_time.'&signature='.$sign;
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-MBX-APIKEY:'.$key));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
$result = json_decode($result, true);
echo '<pre>';
var_dump($result);
echo '</pre>';
?>
Here is an example, using php-curl-class
// Variables
// url, key and secret is on separate file, called using require once
$endPoint = "/api/v3/order/test";
$coin = "BTC";
$fiat = "EUR";
$symbol = $coin . "" . $fiat;
$side = "BUY";
$type = "LIMIT";
$timeInForce = "GTC";
$quantity = 1;
$price = 10000;
$timestamp = time();
// Constructing query arrays
queryArray = array(
"symbol" => $symbol,
"side" => $side,
"type" => $type,
"timeInForce" => $timeInForce,
"quantity" => $quantity,
"price" => $price,
"timestamp" => $timestamp*1000
);
$signature = hash_hmac("sha256", http_build_query($queryArray), $secret);
$signatureArray = array("signature" => $signature);
$curlArray = $queryArray + $signatureArray;
// Curl : setting header and POST
$curl->setHeader("Content-Type","application/x-www-form-urlencoded");
$curl->setHeader("X-MBX-APIKEY",$key);
$curl->post($url . "" . $endPoint, $curlArray);
if ($curl->error) {
echo 'Error: ' . $curl->errorCode . ': ' . $curl->errorMessage . "\n";
}
$order = $curl->response;
print_r($order);
I had the same problem, and nothing of above doesn't helped.
So I finaly figured out how to make order on my way.
So, maybe this helps someone.
function Kupovina($buy_parametri) {
$key = "xxxxxxxxxxxxxxx";
$secret = "xxxxxxxxxxxx";
$s_time = "timestamp=".time()*1000;
$timestamp = time()*1000; //get current timestamp in milliseconds
$sign = hash_hmac('sha256', $buy_parametri."×tamp=".$timestamp, $secret);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.binance.com/api/v3/order");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $buy_parametri."&".$s_time."&signature=".$sign);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded","X-MBX-APIKEY: ".$key));
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
$buy_parametri = "symbol=BTCUSDT&type=market&side=buy&quantity=0.00086";
Call function:
Kupovina($buy_parametri);
I want to pass value from API to array but I am not able to figureout what code I need to write. currently it returns [1481367,7546218] how can I pass this in array
$content = array($result) ;
Below is the API Code
$Login = 8632465; #Must be Changed
$apiPassword = "Kcfve123*"; #Must be Changed
$data = array("Login" => $Login, "Password" => $apiPassword);
$data_string = json_encode($data);
$ch = curl_init('http://client-api.instaforex.com/api/Authentication/RequestPartnerApiToken');
curl_setopt($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)));
$token = curl_exec($ch);
curl_close($ch);
$apiMethodUrl = 'partner/GetReferralAccounts/'; #possibly Must be Changed
$parameters = $Login; #possibly Must be Changed. Depends on the method param
$ch = curl_init('http://client-api.instaforex.com/'.$apiMethodUrl.$parameters);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false); # Turn it ON to get result to the variable
curl_setopt($ch, CURLOPT_HTTPHEADER, array('passkey: '.$token));
$result = curl_exec($ch);
//$result = trim(preg_replace('[]','',curl_exec($ch)));
curl_close($ch);
If the CURL result is "[1481367,7546218]", then to convert this into an array:
`$content = json_decode($result,TRUE); //Here $result = "[1481367,7546218]"`
Printing the variable $content using var_dump() variable will output:
array(2) {
[0] => int(1481367)
[1] => int(7546218)
}
I am using this function for calling method from one server to another in PHP.
function get_url($request_url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
}
$request_url = 'http://second-server-address/listening_page.php?function=somefunction';
$response = get_url($request_url);
Here I am giving a URL with function name. The question is what if the function receives few parameters? How would we pass parameters to the method on another server using CURL.
Just add
$request_url = 'http://second-server-address/listening_page.php?function=somefunction&funcParam1=val&funcParam2.val
Use these passed parameters in your function
If you want to pass parameter as post request then try this.
function post_to_url($url, $data) {
$fields = '';
foreach($data as $key => $value) {
$fields .= $key . '=' . $value . '&';
}
rtrim($fields, '&');
$post = curl_init();
curl_setopt($post, CURLOPT_URL, $url);
curl_setopt($post, CURLOPT_POST, count($data));
curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($post);
curl_close($post);
}
$data = array(
"name" => "c.bavota",
"website" => "http://bavotasan.com",
"twitterID" => "bavotasan"
);
post_to_url("http://yoursite.com/post-to-page.php", $data);
I want to grab json string, set objects and httpheaders in 1.php (for example). Get these values in JSON format and display in next page (2.php).
I tried to use CURL method. I m very new to PHP. Not sure whether CURL method is the best to POST data.. Session or cookie method no need. Is there any other method other than this to POST data?
1.PHP:

2.PHP:
How to post 1.php json value to 2.php.. either through CURL or other posting method.. Tried my best.. cant able to figure out the solution.
Thanks
1.php
$data = array(
'test' => 'data',
'new' => 'array');
$json_data = json_encode($data);
// Only work with your example, curl need full url
$request_url = 'http://teshdigitalgroup.com/2.php';

Is the correct way to send $json data via CURL? in PHP,
I have my $json data in one php, I can send the data information via POST using CURL to my api,??
Do you have some examples, thanks a lot!!
Yes. You can do.
Eg.
// $json_string : Your json String
$ch = curl_init('http://api.example.com/post');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($json_string))
);
$result = curl_exec($ch);
Please find before post:
http://bavotasan.com/2011/post-url-using-curl-php/
In some key on $data, put your $json.
Example
function post_to_url($url, $data) {
$fields = '';
foreach($data as $key => $value) {
$fields .= $key . '=' . $value . '&';
}
rtrim($fields, '&');
$post = curl_init();
curl_setopt($post, CURLOPT_URL, $url);
curl_setopt($post, CURLOPT_POST, count($data));
curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($post);
curl_close($post);
}
$json = json_encode($your_json); //Your json data
$data = array(
"name" => "c.bavota",
"website" => "http://bavotasan.com",
"twitterID" => "bavotasan",
"json" => $json
);
post_to_url("http://yoursite.com/post-to-page.php", $data);
