Question

我试图在＆＃34; http：//www.indianrail.gov.in/cgi_bin/inet_srcdest_cgi_time.cgi"使用asp.net与C＃。问题是我使用的代码无法发布多个数据。当我在＆＃34; http：//www.indianrail.gov.in/cgi_bin/inet_trnnum_cgi.cgi"上发布了一个数据时，此代码已正常运行。但是，当我尝试发布多个数据时，这不起作用。每个输入数据都附有一个隐藏字段，因此我必须对该隐藏字段做什么。

    ASCIIEncoding encoding = new ASCIIEncoding();
    string postData = "lccp_src_stncode=" + src;
    postData += ("&lccp_dstn_stncode=" + des);
    byte[] data = encoding.GetBytes(postData);
    HttpWebRequest myRequest =  (HttpWebRequest)WebRequest.Create("http://www.indianrail.gov.in/cgi_bin/inet_srcdest_cgi_time.cgi");
    myRequest.Method = "POST";
    myRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:11.0) Gecko/20100101 Firefox/11.0";
    myRequest.ContentType = "application/x-www-form-urlencoded";
    myRequest.ContentLength = data.Length;
    Stream newStream = myRequest.GetRequestStream();
    // Send the data.
    newStream.Write(data, 0, data.Length);
    newStream.Close();

    HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse();

    //Get the stream containing content returned by the server.
    newStream = response.GetResponseStream();

    // Open the stream using a StreamReader for easy access.
    StreamReader reader = new StreamReader(newStream,Encoding.UTF8);

    // Read the content.
    string responseFromServer = reader.ReadToEnd();

    File.WriteAllText(@"C:\Users\Zohaib\Documents\Visual Studio 2010\WebSites\WebSite4\App_Data\data.txt", responseFromServer);
    // Clean up the streams.
    reader.Close();
    newStream.Close();
    response.Close();

Answer 1

在POST中，您只需提供一个数据流。该流是否包含“两个”内容，您只需将它们序列化为流。在您的情况下，如果您想发送更多一个查询字符串参数，只需在调用GetBytes之前将其添加到字符串

使用C＃在asp.net中发布多个数据并获取响应
