c# - 使用 DotnetopenAuth 时报告和记录错误

Question

想要连接 Withings API。我在另一个项目中使用了相同的 Controller ，他在那里工作得很好。在站点是 Azure webrole 的项目中(不知道这是怎么回事)它根本不起作用。首先我得到了

The type initializer for 'DotNetOpenAuth.Reporting' threw an exception.

所以我在web.config中关闭了它

reporting enabled="false"

现在我得到了

The type initializer for 'DotNetOpenAuth.Logger' threw an exception.

我不使用 log4net。

 public ActionResult StartOAuth()
    {

        var serviceProvider = GetServiceDescription();
        var consumer = new WebConsumer(serviceProvider, _tokenManager);

        // Url to redirect to
        var authUrl = new Uri(Request.Url.Scheme + "://" + Request.Url.Authority + "/Withings/OAuthCallBack");

        // request access
        consumer.Channel.Send(consumer.PrepareRequestUserAuthorization(authUrl, null, null));

        // This will not get hit!
        return null;
    }

private ServiceProviderDescription GetServiceDescription()
    {
        return new ServiceProviderDescription
        {
            AccessTokenEndpoint = new MessageReceivingEndpoint("https://oauth.withings.com/account/access_token", HttpDeliveryMethods.PostRequest),
            RequestTokenEndpoint = new MessageReceivingEndpoint("https://oauth.withings.com/account/request_token", HttpDeliveryMethods.PostRequest),
            UserAuthorizationEndpoint = new MessageReceivingEndpoint("https://oauth.withings.com/account/authorize", HttpDeliveryMethods.PostRequest),
            TamperProtectionElements = new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
            ProtocolVersion = ProtocolVersion.V10a
        };
    }

事实证明这是 Azure 的错。在 web.config 中有一个部分破坏了 DotnetOpenAuth。删除此部分是一种解决方法。可能添加 log4net 也会解决这个问题，但我没有测试。
