Question

这是我的代码：

HttpWebRequest firstRequest = (HttpWebRequest)HttpWebRequest.Create("http://opizo.com/OEdwHe");
firstRequest.CookieContainer = new CookieContainer();
firstRequest.Method = "GET";
firstRequest.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:48.0) Gecko/20100101 Firefox/48.0";

WebProxy tempProxy = new WebProxy(Proxy+':'+ ProxyPort  /*"127.0.0.1:8888"*/);
tempProxy.BypassProxyOnLocal = false;
tempProxy.UseDefaultCredentials = true;

firstRequest.Accept = "text/html";
firstRequest.UseDefaultCredentials = true;
firstRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;
firstRequest.Proxy = tempProxy;
firstRequest.Timeout = 20000;
WebResponse firstResponse = firstRequest.GetResponse();
System.IO.Stream firstStream = firstResponse.GetResponseStream();
StreamReader firstStreamReader = new StreamReader(firstStream);
string data = firstStreamReader.ReadToEnd();

我要连接的链接是https，但我以http格式输入。代理创建中的Proxy + ProxyPort是代理列表。错误发生在WebResponse firstResponse = firstRequest.GetResponse(); 线。例外是＆＃34;远程服务器返回错误：（403）禁止。＆＃34; 有时当我使用ssl代理时，＆＃34;操作已超时＆＃34;抛出异常，很少会抛出异常但它的概率是千分之一。

更新：我删除了这两行

firstRequest.UseDefaultCredentials = true;
firstRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;

并且错误403的概率从99％变为1％。现在例外＆＃34;操作已经超时＆＃34;扔了。

更新2：403错误返回。我认为没有办法在C＃中使用http代理连接到https站点，解决问题的最佳方法是使用SOCKS库。

使用代理访问https网站时出现Httpwebrequest错误403＃
