到目前为止我已经识别的步骤是,我已将软件包Microsoft.Owin.Security.Google升级到版本2.1.0,因为此版本包含在UseGoogleAuthentication方法中包含选项的功能。
我试图使用Alex Wheat的解决方案链接:
Get ExtraData from MVC5 framework OAuth/OWin identity provider with external auth provider
Startup.Auth.cs(也包括Facebook身份验证)中的代码从此开始:
var facebookAuthenticationOptions = new FacebookAuthenticationOptions() { AppId = "MYAPPID",AppSecret = "MYSECRET" }; facebookAuthenticationOptions.Scope.Add("email"); app.UseFacebookAuthentication(facebookAuthenticationOptions); app.UseGoogleAuthentication();
对此:
var facebookAuthenticationOptions = new FacebookAuthenticationOptions() { AppId = "MYAPPID",AppSecret = "MYSECRET" }; facebookAuthenticationOptions.Scope.Add("email"); app.UseFacebookAuthentication(facebookAuthenticationOptions); var googleOAuth2AuthenticationOptions = new GoogleOAuth2AuthenticationOptions { ClientId = "MYCLIENTID",ClientSecret = "MYSECRET",CallbackPath = new PathString("/en/Account/ExternalLoginCallback"),Provider = new GoogleOAuth2AuthenticationProvider() { } }; app.UseGoogleAuthentication(googleOAuth2AuthenticationOptions);
当我添加选项到Google身份验证后,我的应用程序不允许为Google或Facebook调用ExternalLoginCallback操作(没有更改Facebook代码,但问题仍然影响)。
在前端,点击外部登录按钮后,页面将重定向到下面的链接,并返回一个空的白色屏幕
https……/en/Account/ExternalLoginCallback#__=_ (There is actually only a single underscore before the = sign,SO Syntax removes it if I have it as it appears on my address bar).
为Facebook和
https……/en/Account/ExternalLoginCallback
为谷歌它不像以前那样按照下面的控制器方法进行操作(我试图在这个功能中放置调试断点,而当有google认证选项时,它不会停止。
// GET: /Account/ExternalLoginCallback [AllowAnonymous] public async Task<ActionResult> ExternalLoginCallback(string returnUrl) {
如果我从Google身份验证中删除身份验证选项,则只会恢复为旧的OpenID登录状态,并再次正常工作。
我在这里缺少一些简单的东西吗?还是在Owin.Security.Google Library里面有什么不好的事情引起问题?
解决方法
var googleOAuth2AuthenticationOptions = new GoogleOAuth2AuthenticationOptions { ClientId = "MYCLIENTID",}; app.UseGoogleAuthentication(googleOAuth2AuthenticationOptions);
这对我有用
