Question

我想从我的C＃应用程序发送字符串到我的PHP页面，我尝试了一些我在互联网上找到的不同解决方案。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;

但这只是一个空白页面。我不知道问题是什么。

我很久没有使用过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。

至于你的php，我假设你的foreach方法有开始和结束括号。

好的，我注意到你的c＃中有错误。您获得了两次响应流。这可能会导致一些错误，但这是我将如何构建我的PHP：

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