C# HttpWebRequest.GetResponse 编码 URL

Question

我正在使用 C# HttpWebRequest.GetResponse 和未编码的 URL。但是当我使用提琴手检查请求时，我发现 URL 已编码。我想确认 HttpWebRequest Class 正在对 URL 进行内部编码，但无法在文档中找到它。有人可以指点我可以找到这个或其他验证方法的文档吗？

Answer 1

这里是：

WebRequest.Create（您正在使用该方法创建 HttpWebRequest 对象，对吗？）说 "The Create method uses the requestUriString parameter to create a Uri instance that it passes to the new WebRequest"
https://msdn.microsoft.com/en-us/library/bw00b1dc(v=vs.110).aspx

Uri 的构造函数（由 Create 方法调用）表示 "parses the URI, puts it in canonical format, and makes any required escape encodings"
https://msdn.microsoft.com/en-us/library/z6c2z492(v=vs.110).aspx

//endpoint 是 url 方法可以是 post 或 get... 下面将帮助您捕获来自服务器的任何错误..

让它成为一个函数，这样你就可以很容易地在任何你想用的地方使用它......

   HttpWebRequest httpRequest = (HttpWebRequest)HttprequestObject(endpoints, method);
        using (var streamWriter = new StreamWriter(httpRequest.GetRequestStream()))
        {
            streamWriter.Write(jsonObject);
            streamWriter.Flush();
            streamWriter.Close();
        }
        var result = "";
        HttpWebResponse httpResponse;
        try
        {
            httpResponse = (HttpWebResponse)httpRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
            {
                result = streamReader.ReadToEnd();
            }
        }
        catch (WebException e)
        {
            Console.WriteLine("This program is expected to throw WebException on successful run." +
                                "\n\nException Message :" + e.Message);
            if (e.Status == WebExceptionStatus.ProtocolError)
            {
                Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
                Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
                using (Stream data = e.Response.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    string text = reader.ReadToEnd();
                    Console.WriteLine(text);
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }

或者你想要 class 并且你想使用它来创建 api lib 然后只需复制粘贴这个 class ..这是用于 c# 但几乎更相似的语法 java ...

有了这个你可以访问任何 api 或 url 或者也可以用来将 json 文件传递到服务器..
