如何通过POST参数ASP.Net Web请求？ [英] How to pass POST parameters to ASP.Net web request?

问题描述

我试图使Web请求编程在ASP.NET，使用POST方法。

我想与Web请求发送POST参数以及。事情是这样的：

I'm trying to make web requests programmatically in ASP.NET, using the POST method.
I'd like to send POST parameters with the web request as well. Something like this:

WebRequest req = WebRequest.Create("accounts.craigslist.org/login/pstrdr");
    req.Method = "POST";
    req.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
    //WebRequest.Parameters.add("areaabb","hou");

显然是注释行不起作用。我如何做到这一点？

obviously the commented line does not work. How do I achieve this?

推荐答案

尝试像这样...

  string email = "YOUR EMAIL";
  string password = "YOUR PASSWORD";

  string URLAuth = "https://accounts.craigslist.org/login";
  string postString = string.Format("inputEmailHandle={0}&name={1}&inputPassword={2}", email, password);

  const string contentType = "application/x-www-form-urlencoded";
  System.Net.ServicePointManager.Expect100Continue = false;

  CookieContainer cookies = new CookieContainer();
  HttpWebRequest webRequest = WebRequest.Create(URLAuth) as HttpWebRequest;
  webRequest.Method = "POST";
  webRequest.ContentType = contentType;
  webRequest.CookieContainer = cookies;
  webRequest.ContentLength = postString.Length;
  webRequest.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
  webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
  webRequest.Referer = "https://accounts.craigslist.org";

  StreamWriter requestWriter = new StreamWriter(webRequest.GetRequestStream());
  requestWriter.Write(postString);
  requestWriter.Close();

  StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
  string responseData = responseReader.ReadToEnd();

  responseReader.Close();
  webRequest.GetResponse().Close();
