从c#应用程序发送一个字符串到PHP - Send a string from C# app to PHP

Send a string from C# app to PHP

本文关键字：一个字符串 PHP 应用程序 | 更新日期: 2023-09-26

我想从我的c#应用程序发送字符串到我的PHP页面，我尝试了一些不同的解决方案，我在互联网上发现。其中之一是:

c#代码:

        string url = "http://localhost:8080/test.php";
        string str = "test";
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "POST";
        string Data = "message=" + str;
        byte[] postBytes = Encoding.ASCII.GetBytes(Data);
        req.ContentType = "application/x-www-form-urlencoded";
        req.ContentLength = postBytes.Length;
        Stream requestStream = req.GetRequestStream();
        requestStream.Write(postBytes, 0, postBytes.Length);
        requestStream.Close();
        HttpWebResponse response = (HttpWebResponse)req.GetResponse();
        Stream resStream = response.GetResponseStream();
        var sr = new StreamReader(response.GetResponseStream());
        string responseText = sr.ReadToEnd();

和PHP代码:

foreach($_POST as $pdata)
echo $pdata;

但这只是一张空白页。我不知道是什么问题

我已经很长时间没有使用c#了，但这应该是解决方案:

    string url = "http://localhost:8080/test.php";
    string str = "test";
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    req.Method = "POST";
    string Data = "message=" + str;
    UTF8Encoding utf8 = new UTF8Encoding();
    byte[] postBytes = utf8.GetBytes(Data);
    req.ContentType = "application/x-www-form-urlencoded";
    req.ContentLength = postBytes.Length;
    Stream requestStream = req.GetRequestStream();
    requestStream.Write(postBytes, 0, postBytes.Length);
    requestStream.Close();
    HttpWebResponse response = (HttpWebResponse)req.GetResponse();
    Stream resStream = response.GetResponseStream();
    var sr = new StreamReader(resStream);
    string responseText = sr.ReadToEnd();

我所做的是将编码从ASCII更改为UTF8。UTF8是application/x-www-form-urlencoded所期望的。

对于你的php，我假设你的foreach方法上有左括号和右括号。

编辑:

好吧，我注意到你c#中的一个错误。你收到了两次响应流。这可能会导致一些错误，但这是我如何构建我的php:

<?php
foreach($_POST as $key => $value){
    echo $value . "<br>";
}
?>
