Web请求错误407需要代理身份validation

尝试从网站获取GetResponse;

using System.Text; using System.Net; using System.IO; namespace DutyPharmacy751013 { class Program { static void Main(string[] args) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/"); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Encoding encoding = Encoding.GetEncoding(response.CharacterSet); Stream stream = response.GetResponseStream(); StreamReader reader = new StreamReader(stream, encoding); string responseText= reader.ReadToEnd(); } } } 

此代码适用于win7和LAN以及win8和任何无线连接，但不适用于win8和LAN错误：407需要代理身份validation。 有没有解决方案。 谢谢。

Answer 1

尝试添加代理凭据来请求并提供网络凭据

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/"); request.Credentials = new NetworkCredential("username", "pw"); WebProxy webProxy = new WebProxy("http://myproxy.net:8080/", true) { Credentials = new NetworkCredential("username", "pw"), UseDefaultCredentials = false }; request.Proxy = webProxy; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //rest of the code... 

编辑

对于您创建的请求，您可以通过在请求中使用空代理来禁用请求级别的自动代理检测

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/"); request.Proxy = null; //rest of the code 

Answer 2

 WebProxy webProxy = new WebProxy("http://myproxy.net:8080/", true) { UseDefaultCredentials = false, Credentials = new NetworkCredential("username", "pw") }; 

请注意正确的顺序来设置属性{其他明智的失败对我来说}
