Question

我正在使用带有未编码的URL的C＃HttpWebRequest.GetResponse。但是当我使用fiddler检查请求时，我发现URL已被编码。我想确认HttpWebRequest Class是在内部编码URL但在文档中找不到它。有人能指出我可以找到这个或其他方式验证它的文档吗？

Answer 1

这是：

WebRequest.Create（您正在使用该方法创建HttpWebRequest对象，对吧？）＆＃34; Create方法使用requestUriString参数创建一个Uri实例，并将其传递给新的WebRequest＆＃34;
https://msdn.microsoft.com/en-us/library/bw00b1dc(v=vs.110).aspx

Uri的构造函数（由Create方法调用）表示它＆＃34;解析URI，将其置于规范格式，并进行任何必需的转义编码 ＆＃34;

//端点是url，方法可以发布或获取...以下内容将帮助您从服务器中捕获任何错误..

使它成为一个功能，因此您可以轻松地在任何您想要的地方使用...

   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);
        }

或者你想要类，你想用来创建api lib然后只需复制粘贴这个类..这是用于c＃但几乎是java的similer语法......

这个你可以访问任何api或url，或者也用于将json文件传递给服务器..
