问题描述

大家好！我想用C#编写一个程序，该程序将自动创建电子邮件帐户，为此，我编写了一个验证码阅读器类.现在，我想创建一个POST命令，该命令会将有关用户的数据发送到服务器.如何正确确定命令格式?
这是我写的:

Hello everybody! I want to write a program in C# that will automatically create email accounts and for this purpose I wrote a captcha reader class. Now I want to create a POST command that will send to the server the data about user. How can I correctly determine the format of the command?
HEre is what i wrote:

//-------------------------------------------------------------------------------
//Create HttpWebRequest instance
            HttpWebRequest postRequest = (HttpWebRequest)WebRequest.Create(url);
//specify the method
            postRequest.Method = "Post";
            postRequest.ContentType = "application/x-www-form-urlencoded";
//create namevalue collection for sending to the server name value pairs (is it //correctly?)
            NameValueCollection nvc = new NameValueCollection();
            nvc.Add("_token", sessionID);
            nvc.Add("_uname", "lalala123");
            .........
//I dont know how should I exactly create the message
            byte[] btPostData = Encoding.ASCII.GetBytes("_token" + nvc.Get("_token"));

            postRequest.ContentLength = btPostData.Length;
            Stream postData = postRequest.GetRequestStream();
            postData.Write(btPostData, 0, btPostData.Length);
            HttpWebResponse response2 = (HttpWebResponse)postRequest.GetResponse();
            Stream responseStream2 = response.GetResponseStream();
            StreamReader reader2 = new StreamReader(responseStream2);
            String response22 = reader2.ReadToEnd();
            ;
//-------------------------------------------------------------------------------

提前谢谢！

推荐答案

我不知道您想要(需要)发送什么参数，但是一般而言，如何创建post params可以找到 ^ ].网上还有许多其他示例.

通常，帖子数据的格式与其他任何查询字符串一样(Key1 = Value1& Key2 = Value2等等...)
您的帖子数据将如下所示: _token = 100& _uname = lalala123
同样，在创建发布数据时，您需要使用

Hi,

I don''t know what parameters you want (need) to send but how create post params in general you can find here[^]. There are many other examples on net.

In general post data is formatted like any other query string (Key1=Value1&Key2=Value2 and so on...)
Yours post data will look like this: _token=100&_uname=lalala123
Also when you creating post data you need to encode values using

System.Web.HttpUtility.UrlEncode()

方法对值进行编码.
这几乎是您成功完成发帖请求所需要的全部...

method.
And that''s pretty much all you need to make successful post request...
