我收到包含JSON的POST，问题是当我收到$ _POST为空时.为了测试何时收到POST，我创建了一个包含$ _POST，$ _ GET和$ _REQUEST的文件，它们都是空的.

I'm receiving a POST that contains a JSON, the problem is when I receive that the $_POST is empty. In order to test when I receive the POST I create a file that contais the $_POST, $_GET and $_REQUEST and they are all empty.

正在发送请求的客户端正在执行以下操作:

The client that is sending the request is doing something like this:

$itemJson = '{
      "id": 00,
      "value": "ok"
    }';

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: '. strlen($itemJson))
    );
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $itemJson);
    curl_close($ch);

说实话，因为没有设置参数，所以我并不在意如何获取这些数据.

To be honest I don't understant how I'm getting this data since there's no parameter set.

有什么想法吗?

推荐答案

按如下所示在PHP中尝试(当请求是application/json时，则不会将数据放入$ _POST)

Try in PHP as below (When request is an application/json, then you will not get data into $_POST)

var_dump(json_decode(file_get_contents("php://input")));
