php curl post json [英] php curl post json

问题描述

我发现如果我尝试一个PHP POST卷曲，postvars发送正常。一旦我添加了内容类型的httpheader： application / json postvars不会再跨越。我已经尝试过postvars作为JSON字符串和查询字符串。

帮助？

**显示一些代码**

  $ ch = curl_init（）; 
 
 $ post = json_encode（array（'p1'=>'blahblahblah'，'p2'=> json_encode（array（4,5,6））））; 
 
 $ arr = array（）; 
 array_push（$ arr，'Content-Type：application / json; charset = utf-8'）; 
 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ arr）; 
 curl_setopt（$ ch，CURLOPT_URL，'https://domain.com/file.php'）; 
 curl_setopt（$ ch，CURLOPT_POST，true）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ post）; 
 
 curl_exec（$ ch）; 
 curl_close（$ ch）; 
  

解决方案

真正的HTTP Post， PHP自动化必须使用name = value对格式化，在PHP中最好的方法是使用http_build_query函数。

http://ca2.php.net/manual/en/function.http-build-query.php p>

有一个在PHP手册中使用curl的示例：

http://ca2.php.net/manual/en/function.curl-exec.php#98628 p>

 <？php 
 
 print_r（json_decode（file_get_contents（'php：// input'）））; 
  

I've found that if I try a PHP POST curl, the postvars are sent fine. Once I add the httpheader of content-type: application/json the postvars don't go across anymore. I've tried the postvars as a JSON string and as a query string.

help?

** Showing some code **

$ch = curl_init();

$post =  json_encode(array('p1' => 'blahblahblah', 'p2' => json_encode(array(4,5,6))));

$arr = array();
array_push($arr, 'Content-Type: application/json; charset=utf-8');

curl_setopt($ch, CURLOPT_HTTPHEADER, $arr);
curl_setopt($ch, CURLOPT_URL, 'https://domain.com/file.php');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

curl_exec($ch);
curl_close($ch);

解决方案

A real HTTP Post, that gets broken into an array automagically by PHP must be formatted in name=value pairs, the best way to do this in PHP is using the http_build_query function.

http://ca2.php.net/manual/en/function.http-build-query.php

There is an example that works in the PHP Manual using curl:

http://ca2.php.net/manual/en/function.curl-exec.php#98628

What you're doing is a 'RAW' post, see this other question:
