& quot;应用程序/json& quot;的类型防止发布post变量 [英] Type of "application/json" prevents post variables from being sent

问题描述

我发现，如果尝试使用PHP POST curl，postvars会很好地发送.一旦我添加了内容类型的httpheader: application/json ，postvars就不会再出现了.我已经尝试过将postvars作为JSON字符串和查询字符串.

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 any more. I've tried the postvars as a JSON string and as a query string.

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://example.com/file.php');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

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

推荐答案

一个真正的HTTP帖子，被PHP自动分解成一个数组，必须格式化为name = value对，在PHP中做到这一点的最佳方法是使用http_build_query函数.

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.

PHP手册中有一个使用curl的示例:

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