PHP通过CURL POST发送JSON

问题描述：

I cannot figure out why this function is not POSTing, any ideas? Thanks! I am trying to send JSON data to a server, and I am getting no error or feedback, the var_dump($response) just gives me 'null'.

function postToDatabase($data, $thingName){
  $content = json_encode($data);

  $curl = curl_init('http://someurl.com/thing'. $thingName .'/otherthing');
  curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
  curl_setopt($curl, CURLOPT_HEADER, false);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_HTTPHEADER,
    array("Content-type: application/json"));
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //curl error SSL certificate problem, verify that the CA cert is OK

$result     = curl_exec($curl);
$response   = json_decode($result);
var_dump($response);
curl_close($curl);
}


/* post to url */
postToDatabase($someData, $thingName);

my JSON $content:

{
    "email": null,
    "stripeToken": "aidfat9s8d7ftas7df9asjd7fy0aksd",
    "stripeShippingName": "A Test User",
    "stripeShippingAddressLine1": "1we2e12",
    "stripeShippingAddressZip": "62650",
    "stripeShippingAddressState": "IL",
    "stripeShippingAddressCity": "Jacksonville",
    "stripeShippingAddressCountry": "United States",
    "products": [
        {
            "productId": "897349864",
            "sizeId": "4",
            "colorId": "6",
            "units": 1
        }
    ]
}

我无法弄清楚为什么这个函数不是POST，有什么想法吗？谢谢！我正在尝试将JSON数据发送到服务器，我没有收到任何错误或反馈，var_dump（$ response）只给我'null'。 p>

   function postToDatabase（$ data，$ thingName）{
 $ content = json_encode（$ data）; 
 
 $ curl = curl_init（'http://someurl.com/thing'。$ thingName。'/ otherthing'）  ; 
 curl_setopt（$ curl，CURLOPT_CUSTOMREQUEST，“POST”）; 
 curl_setopt（$ curl，CURLOPT_HEADER，false）;

 curl_setopt（$ curl，CURLOPT_POSTFIELDS，$ content）; 
curl_setopt（$ curl，CURLOPT_SSL_VERIFYPEER，false）;  //卷曲错误SSL证书问题，验证CA证书是否正常
 
 $ result = curl_exec（$ curl）; 
 $ response = json_decode（$ result）; 
var_dump（$ response）; 
curl_close（$  curl）; 
}

your issue could be because of error happening in curl or while decoding json string using json_decode() I would recommend you to consider implementing more error handling, using related error functions, something like:

$result     = curl_exec($curl);
if($result == false){
     var_dump(curl_error($curl)); // http://se2.php.net/manual/en/function.curl-error.php
}
$response   = json_decode($result);
if ($resonse == null){
    var_dump(json_last_error());
}
var_dump($response);
curl_close($curl);

If you are getting something in $result, but not in $response, could it be your JSON is malformed? Try using: http://www.php.net/manual/en/function.json-last-error.php

or you could use http://jsonlint.org/ to check the raw $result;
