C＃ - Json的POST请求发送，但不是由PHP服务器接收 [英] C# - Json POST request sent but not received by PHP server

问题描述

我送从C＃应用windowsform托管于OpenShift（红帽）PHP服务器的HTTP请求。我现在用的是POST方法，使用JSON数据

I am sending a HTTP request from a C# windowsform application to PHP server hosted on OpenShift (Redhat). I am using the method POST, with Json data.

的问题是：

• 数据似乎是正确发送（我看到在Wireshark的数据包）


• PHP脚本是正确启动，我认为收到POST信息在日志中看到

<被beeing收到LI>但没有POST数据..

下面是C＃代码

string json = "{\"user\":\"test\"," +
                "\"n\":\"2\"}";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://........rhcloud.com/webservices.php");

request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = json.Length;

using (var streamWriter = new StreamWriter(request.GetRequestStream()))
{
    streamWriter.Write(json);
    streamWriter.Close();

    var httpResponse = (HttpWebResponse)request.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
         var result = streamReader.ReadToEnd();
         Debug.WriteLine("R : " + result);
    }
}

下面是PHP代码：

echo "Start Saving ! ";

// Handle Posted Data From C# App
if (isset($_POST) && !empty($_POST))
{
    echo 'Data Recieved';
}
else
{
  // Error
  echo 'No POST Data Found';
}   

函数总是返回：开始存钱！无POST数据发现。

The function always return : "Start Saving ! No POST Data Found".

这里是服务器上的日志行：

Here is the log line on the server :

< STRONG>这里是Wireshark中行：

Here is the line in wireshark :

时有人看到这个问题？不要犹豫，告诉我，如果我不明确。
难道是Openshift其拦截的数据？请问我的PHP文件有问题？

Is someone seeing the problem? Do not hesitate to tell me if I am not clear. Could it be Openshift which intercept the data ? Does my php file have a problem?

推荐答案

PHP的 $ _ POST 做不明白JSON。

PHP's $_POST does not understand JSON.

你想要的是沿

// Error handling is left as an exercise
$input = json_decode(file_get_contents('php://input'), true);

您应该然后就可以使用 $输入你似乎顺便要使用 $ _ POST 。请参见 json_decode 更多的旋钮摆弄。

You should then be able to use $input the way you seem to want to use $_POST. See json_decode for additional knobs to twiddle.
