C# 如何解决.NET.CORE中的代理服务器407错误

因此，我有一些代码可以访问网站的html，但只有在visualstudios.Framework for c#中将这些代码输入app.config时才可以访问

    <system.net> <defaultProxy useDefaultCredentials="true" /> </system.net>

---

ps>.NET核心之间的下一行没有

app.config

文件。这需要在代码中进行配置

---

使用

request.Proxy.Credentials=System.Net.CredentialCache.DefaultCredentials

HttpWebRequest

在调用

GetResponse（）

之前，用于进行HTTP调用的对象需要设置上述属性。在.NETCore中，它不会像在.NETFramework中那样使用

app.config

文件中的设置。

     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        if (response.StatusCode == HttpStatusCode.OK)
        {
            Stream receiveStream = response.GetResponseStream();
            StreamReader readStream = null;
            if (response.CharacterSet == null)
            {
                readStream = new StreamReader(receiveStream);
                Console.WriteLine("Sorry , somethings faulty");

            }
            else
            {
                readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
                readStream.ToString();
                // Console.WriteLine(readStream);
            }
            string ImpureTexta = readStream.ReadToEnd().ToString();
            BaseHTML = ImpureTexta;  ///turns ImpureText in class to the actual html code so it can be used by entire program
            Console.WriteLine(BaseHTML);
            Console.WriteLine(" <--------------------------------Extraction  B Complete --------------------------------->");
        }
