Question

我使用VS2015，C＃。

我在使用Google登录时遇到问题。从我的调试配置（localhost）一切正常。发布到服务器后，谷歌登录窗口根本无法打开。并且没有例外。 这是我的代码：

[AllowAnonymous]
public async Task LoginWithGoogle()
{
    HttpRequest request = System.Web.HttpContext.Current.Request;
    string redirectUri = ConfigurationReaderHelper.GetGoogleRedirectUri();

    try
    {            
        ClientSecrets secrets = new ClientSecrets
        {
            ClientId = "***",
            ClientSecret = "***"
        };

        IEnumerable<string> scopes = new[] { PlusService.Scope.UserinfoEmail, PlusService.Scope.UserinfoProfile };

        GoogleStorageCredentials storage = new GoogleStorageCredentials();

        dsAuthorizationBroker.RedirectUri = redirectUri;
        UserCredential credential = await dsAuthorizationBroker.AuthorizeAsync(secrets,
            scopes, "", CancellationToken.None, storage);
    }
    catch(Exception ex)
    {
        throw ex;
    }            
}


//just getting value from applicationSettings - web.config
            public static string GetGoogleRedirectUri()
            {
    #if DEBUG
                return GetValueFromApplicationSettings("RedirectUriDEBUG");
    #elif PRODUKCIJA
                return GetValueFromApplicationSettings("RedirectUriSERVER");            
    #endif
            }

当然，我将服务器的地址添加到原始uri以及谷歌控制台上的授权重定向uri以供开发人员使用。 （就像我为localhost所做的那样）。我只是不明白它出了什么问题，为什么登录窗口没有打开？

修改

添加类dsAuthorizationBroker（我的第一篇文章中遗漏了 - 对不起该帖子）：

namespace Notes
{
    public class dsAuthorizationBroker : GoogleWebAuthorizationBroker
    {
        public static string RedirectUri;

        public static async Task<UserCredential> AuthorizeAsync(
            ClientSecrets clientSecrets,
            IEnumerable<string> scopes,
            string user,
            CancellationToken taskCancellationToken,
            IDataStore dataStore = null)
        {
            var initializer = new GoogleAuthorizationCodeFlow.Initializer
            {
                ClientSecrets = clientSecrets,
            };
            return await AuthorizeAsyncCore(initializer, scopes, user,
                taskCancellationToken, dataStore).ConfigureAwait(false);
        }

        private static async Task<UserCredential> AuthorizeAsyncCore(
            GoogleAuthorizationCodeFlow.Initializer initializer,
            IEnumerable<string> scopes,
            string user,
            CancellationToken taskCancellationToken,
            IDataStore dataStore)
        {
            initializer.Scopes = scopes;
            initializer.DataStore = dataStore ?? new FileDataStore(Folder);
            var flow = new dsAuthorizationCodeFlow(initializer);
            return await new AuthorizationCodeInstalledApp(flow,
                new LocalServerCodeReceiver())
                .AuthorizeAsync(user, taskCancellationToken).ConfigureAwait(false);
        }
    }


    public class dsAuthorizationCodeFlow : GoogleAuthorizationCodeFlow
    {        
        public dsAuthorizationCodeFlow(Initializer initializer)
            : base(initializer) { }

        public override AuthorizationCodeRequestUrl
                       CreateAuthorizationCodeRequest(string redirectUri)
        {            
            return base.CreateAuthorizationCodeRequest(dsAuthorizationBroker.RedirectUri);            
        }
    }
}

Answer 1

public static async Task<UserCredential> AuthorizeAsync

此方法已在GoogleWebAuthorizationBroker中声明，因此如果您打算将此函数的实现优先于基本实现，则需要使用new关键字。

public new static async Task<UserCredential> AuthorizeAsync

这就是为什么我假设您在

之前停止记录行的原因

UserCredential credential = await dsAuthorizationBroker.AuthorizeAsync

此时，它正在调用基础实现。

除此之外，我通常倾向于使用DotNetOpenAuth与Google进行互动，并且有很多简单的示例可供使用，例如here和here ..但如果你真的想要要使用Google Apis滚动自己，这是最好的place to start
