Question

我正在尝试欺骗网页表单，以便我可以通过C＃程序而不是网站输入数据。如果我知道表单内容，我认为下面的代码可以工作，但它没有（服务器端数据似乎没有改变）。如果我将其保存为网页并在浏览器中运行它，这样可以正常工作。

<form action="subDOB" method="POST" class="log">
<input type="hidden" name="id" value="27">
<textarea class="logarea" rows="15" name="birth" spellcheck=FALSE>2/27/89
</textarea><br/><br/>
<input class="btn btn-inverse" type="submit" value="Edit info">
</form>

我的代码（在一个按钮中）：

WebRequest req = WebRequest.Create("https://site.com/subDOB");//not a real site name :)
        string postData = @"id=27&birth=4/01/88";

        byte[] send = Encoding.Default.GetBytes(postData);
        req.Method = "POST";
        req.ContentType = "application/x-www-form-urlencoded";
        req.ContentLength = send.Length;

        Stream sout = req.GetRequestStream();
        sout.Write(send, 0, send.Length);
        sout.Flush();
        sout.Close();

        WebResponse res = req.GetResponse();
        StreamReader sr = new StreamReader(res.GetResponseStream());
        string returnvalue = sr.ReadToEnd();
        rtb.AppendText(returnvalue);// the return value is (apparently) the entire contents of the start page that I had to go through to get to the form
