Question

我想使用$ _POST将数据从C＃（Windows窗体应用程序）发布到PHP，但是在VS的Locals窗口中使用echo / var_dump检查时获得空值，同时显示带有已发布数据的ResponseStream的值。我不知道问题是否出在C＃方法或PHP脚本中。

在Pass data from C# to PHP中，还有一些其他问题，在我的情况下，我将其应用如下。

PHP脚本（post.php）：

<?php

// *** Use $_GET, the echo works when testing parameters from browser's address bar, but GET method in C# will fail. 

//if(isset($_POST['data'])){
//if($_SERVER['REQUEST_METHOD'] == "POST"){
  $data = $_POST['data'];
  echo "Hello, ";
  echo $data;
//}

?>

<!-- for debug purpose -->
<pre>
<?php 
var_dump($_POST); 
//print_r($_POST);

var_dump($_REQUEST);
?>
</pre>

C＃方法：

public string SendPost(string url, string postData)
{
    string webpageContent = string.Empty;

    ServicePointManager.Expect100Continue = true;
    ServicePointManager.SecurityProtocol = (SecurityProtocolType)(0x30 | 0xc0 | 0x300 | 0xc00);    

    // https://stackoverflow.com/questions/12506575/how-to-ignore-the-certificate-check-when-ssl
    ServicePointManager.ServerCertificateValidationCallback +=
        delegate (object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,
                System.Security.Cryptography.X509Certificates.X509Chain chain,
                System.Net.Security.SslPolicyErrors sslPolicyErrors)
        {
            return true; // **** Always accept
    };


    try
    {
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
        webRequest.Method = "POST";
        webRequest.ContentType = "application/x-www-form-urlencoded";
        webRequest.ContentLength = byteArray.Length;

        using (Stream webpageStream = webRequest.GetRequestStream())
        {
            webpageStream.Write(byteArray, 0, byteArray.Length);
        }

        using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
        {
            using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))
            {
                webpageContent = reader.ReadToEnd();
            }
        }
    }
    catch (Exception ex)
    {        
        MessageBox.Show(ex.Message);
        return null;
    }
    MessageBox.Show("Data has been posted.");
    return webpageContent;
}

这是我如何调用方法：

String pData = "TestString";
SendPost("https://websites/post.php", String.Format("data={0}", pData));

结果

在“本地”窗口中，“ webpageContent”的返回值：

Hello, TestString

在浏览器中，“ https://websites/post.php”：

Hello,

如何在PHP中保留/显示/使用从C＃接收的值？

使用PHP中的“ POST”方法显示/使用从C＃接收的数据
