帮助使用ASP.NET HttpWebRequest [英] Help with ASP.NET HttpWebRequest

问题描述

我开始学习ASP.NET和C#，以更加熟悉我想制作开放源代码插件的技术 BugTracker.Net 应用程序.我堆叠的是要添加新问题的应用程序，需要在insert_bug.aspx上获取HttpWebRequest

I began to learn ASP.NET and C#, to get more familiar with techniques I want to make plugin for open source BugTracker.Net application. Where I am stacked is that for adding new issue application need to get HttpWebRequest on insert_bug.aspx

我确实在处理像这样的代码上做了基本的事情:

I did make basic thing working on code like this:

string Url = "http://localhost:8090/insert_bug.aspx";
        string post_data =
                     "&username=admin"
                    + "&password=admin"
                    + "&short_desc=Description"
                    + "&comment=Comment"
                    + "&projectid=1"

        byte[] bytes = Encoding.UTF8.GetBytes(post_data);
        HttpWebResponse res = null;
        try
        {
            HttpWebRequest req = (HttpWebRequest) System.Net.WebRequest.Create(Url);
            req.Credentials = CredentialCache.DefaultCredentials;
            req.PreAuthenticate = 
            req.Method = "POST";
            req.ContentType= "application/x-www-form-urlencoded";
            req.ContentLength=bytes.Length;
            Stream request_stream = req.GetRequestStream();
            request_stream.Write(bytes,0,bytes.Length);
            request_stream.Close();
            res = (HttpWebResponse) req.GetResponse();
        }
        catch (Exception e)
        {
            Console.WriteLine("HttpWebRequest error url=" + Url);
            Console.WriteLine(e);
        }

我也想将CATEGORY插入到我的问题中，并阅读insert_bug.aspx上的代码，我资助了用于定义打开问题的类别的部分

I want to insert also CATEGORY into my issues and reading code on insert_bug.aspx i fund part for defining category for opening issue

if (Request["$CATEGORY$"] != null && Request["$CATEGORY$"] != "") { categoryid = Convert.ToInt32(Request["$CATEGORY$"]); }

问题:如何以及如何在请求中添加"$ CATEGORY $"，以便添加的问题已定义类别.

Question: What and How I can add "$CATEGORY$" to my request so the issues I added have defined category.

推荐答案

如果我正确理解了您的问题，如果要添加类别，则需要查找类别ID并将其作为变量添加到POST数据中.例如，如果您想要的类别的ID为1(在BugTracker.NET中为错误")，则可以使用以下方式:

If I understand your question correctly, if you want to add a category, you need to look up the category ID and add it as a variable in your POST data. For example, if the category you want has its ID=1 ("bug" in BugTracker.NET), then you'd use this:

    string post_data =
                 "&username=admin"
                + "&password=admin"
                + "&short_desc=Description"
                + "&comment=Comment"
                + "&projectid=1"
                + "&$CATEGORY$=1";

顺便说一句，在像这样的简单HTTP客户端方案中，最好使用

BTW, in simple HTTP client scenarios like this one you're better off using the WebClient class. You can accomplish the same thing in many fewer lines of code.
