过帐方法并使用C#的某些值进行重定向 [英] Post Method and Redirect With Some Values Without Form C#

问题描述

<form action="https://somewebsiteaddrest" method="post">
   <input name="Var1"  type="hidden" value="Variable 1 value" />
   <input name="Var2"  type="hidden" value="Variable 2 value" />
   <input name="Var3"  type="hidden" value="Variable 3 value" />
   <input name="Var4"  type="hidden" value="Variable 4 value" />
   <input name="Var5"  type="hidden" value="Variable 6 value" />
   <input type="submit" value="Go now" />
</form>

我想在不使用此表单和 javascript frm.submit();

I want to create equal post method and redirection (in C#) without using this form and javascript frm.submit();

我有一个C#代码段，希望可以完成.

I've a C# code snippet which I expect to do the stuff.

    WebRequest request = WebRequest.Create(url);
    request.Method = "POST";
    string postData = "What to write here? here should be variable i guess.";
    byte[] byteArray = Encoding.UTF8.GetBytes(postData);
    request.ContentType = "application/x-www-form-urlencoded";
    request.ContentLength = byteArray.Length;
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(byteArray, 0, byteArray.Length);
    dataStream.Close();
    WebResponse response = request.GetResponse();
    Console.WriteLine(((HttpWebResponse)response).StatusDescription);
    dataStream = response.GetResponseStream();
    StreamReader reader = new StreamReader(dataStream);
    string responseFromServer = reader.ReadToEnd();
    Console.WriteLine(responseFromServer);
    reader.Close();
    dataStream.Close();
    response.Close();


string postData

用form和form.submit()在postData中写什么才能获得与原来相同的效果?预先感谢

what to write in postData to get the same effect as it will be by using form and form.submit()? Thanks in advance

推荐答案

发布数据应为URL编码的表单数据，即键=值对，以&个字符分隔.使用 UrlEncode方法对值进行编码:

The post data should be URL-encoded form data, i.e. key=value pairs separated by & characters. Use the UrlEncode method to encode the values:

string postData =
  "Var1=" + HttpUtility.UrlEncode("Variable 1 value")+
  "&Var2=" + HttpUtility.UrlEncode("Variable 2 value")+
  "&Var3=" + HttpUtility.UrlEncode("Variable 3 value")+
  "&Var4=" + HttpUtility.UrlEncode("Variable 4 value")+
  "&Var5=" + HttpUtility.UrlEncode("Variable 6 value");
