(407) 需要代理身份验证 ( ISA 服务器需要授权才能完成请求.对 Web 代理筛选器的访问被拒绝

Question

我知道这个错误很常见，但我试图将解决方案应用于这个问题，但无法解决。

这是我的代码：

        var endpoint = new EndpointAddress(new Uri("http://www3prz.bancobonsucesso.com.br/Servicos/app.svc"), EndpointIdentity.CreateDnsIdentity("bancobonsucesso.com.br"));
        var binding = new WSHttpBinding();
        binding.UseDefaultWebProxy = true;
        binding.Security.Mode = SecurityMode.Message;
        binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
        binding.Security.Message.EstablishSecurityContext = true;
        binding.Security.Message.NegotiateServiceCredential = true;
        var customBinding = new CustomBinding(binding);
        SymmetricSecurityBindingElement security = customBinding.Elements.Find<SymmetricSecurityBindingElement>();
        security.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
        security.LocalClientSettings.DetectReplays = false;
        SecureConversationSecurityTokenParameters secureTokenParams = (SecureConversationSecurityTokenParameters)security.ProtectionTokenParameters;
        SecurityBindingElement bootstrap = secureTokenParams.BootstrapSecurityBindingElement;
        bootstrap.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
        bootstrap.LocalClientSettings.DetectReplays = false;
        ws = new ServicoClient(customBinding, endpoint);
        ws.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
        ws.ClientCredentials.UserName.UserName = "test";
        ws.ClientCredentials.UserName.Password = "test";
        var return = ws.EmitirBoleto("test");

Answer 1

在 WCF 绑定中使用 useDefaultWebProxy：

<bindings>
<basicHttpBinding>
<binding name="bindingName"  useDefaultWebProxy="true">
WebProxy wproxy = new WebProxy("new proxy",true);
wproxy.Credentials = new NetworkCredential("user", "pass");
WebRequest.DefaultWebProxy = wproxy;

此错误可能会出现代理设置问题。请使用您的网络浏览器检查代理设置。刚刚更改了连接设置 选项 ->设置 ->连接设置到自动检测代理设置

祝你好运。。。
