facebook - MVC3 Web 项目错误 : "An attempt was made to access a socket in a way forbidden by its access permissions 10.10.0.1:3128"

Question

我将 MVC3 Web 项目发布到 Azure。当我尝试使用 Facebook 授权时，出现以下错误。

其他信息:

• callbackUrl = http://site.azurewebsites.net/Facebook/AddSocialAccount
• authenticateUrl = https://graph.facebook.com/oauth/authorize?client_id= *&response_type=code&redirect_uri=http%3A%2F%2Fsite.azurewebsites.net%2FFacebook%2FAddSocialAccount&scope=publish_stream%2Cemail%2Cuser_birthday

因此应用程序在 Facebook 上授权，转到 AddSocialAccount 操作并在字符串中失败:

var profile = this.Provider.GetUserProfile(code);

去哪里:

protected override Task<AccessGrant> PostForAccessGrantAsync(string accessTokenUrl, NameValueCollection request)
    {
        return this.RestTemplate.PostForObjectAsync<NameValueCollection>(accessTokenUrl, request)
            .ContinueWith<AccessGrant>(task =>
            {
                string expires = task.Result["expires"];
                return new AccessGrant(task.Result["access_token"], null, null, expires != null ? new Nullable<int>(Int32.Parse(expires)) : null);
            });
    }

有错误的字符串是

string expires = task.Result["expires"];

错误:

Server Error in '/' Application.

当我使用带有 Azure 连接字符串的本地计算机时，我没有收到此错误(我更改了 fb 上的域和 url)。 感谢您的任何想法!

我解决了这个问题。我的 web.config 中有默认代理。

<system.net>
<defaultProxy>
  <proxy usesystemdefault="True" proxyaddress="http://10.10.0.1:3128" bypassonlocal="True" />
</defaultProxy>

我把它删除了。并且授权工作正确。
