Question

我无法弄清楚为什么这个功能不是POST，任何想法？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）只是给了我'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);

我的JSON $内容：

{
    "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
        }
    ]
}

Answer 1

如果你在$ result中获得了某些东西，但是没有在$ response中，那么你的JSON是否格格不入？尝试使用：http://www.php.net/manual/en/function.json-last-error.php

或者您可以使用http://jsonlint.org/来检查原始$ result;

您的问题可能是由于curl中发生错误或使用json_decode()解码json字符串时我建议您考虑使用相关的错误函数实现更多错误处理，例如：

$result     = curl_exec($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);

以下是CURL错误列表：http://se2.php.net/manual/en/function.curl-errno.php
