Rails用户(来自omniauth-google-oauth2文档):

修复redirect_uri在Rails中的协议不匹配 只需要根据Rails.env在OmniAuth中设置full_host。 #配置/初始化/ omniauth.rb OmniAuth.config。full_host = Rails.env.production?？ 'https://domain.com': 'http://localhost:3000'

记住:不要包括后面的"/"

更新—>适用于Android应用程序

只使用:

http://localhost/oauth2callback

如果你处理自己的逻辑没有重定向链接的web应用程序

The trick is to input the right redirect url at the point of creating the ID. I found that updating the redirect url once the ID has been created via an 'Edit' just doesn't get the job done. What also worked for me is duplicating the entire 'vendor' folder and copying it to the same location where the 'oauth' file is (just until you successfully generate the token and then you can delete the duplicate 'vendor' folder). This is because trying to point to the vendor folder via '../vendor/autoload' didn't work for me.

因此，删除您现有的麻烦客户端OAuth ID，并尝试这种方法，它将工作。

如果你正在使用passport js，你正在heroku中部署你的应用程序，你需要在passport策略中添加这个设置proxy: true

passport.use(new GoogleStrategy(
    {
        clientID: keys.googleClientID,
        clientSecret: keys.googleClientSecret,
        callbackURL: '/auth/google/callback',
        proxy: true
    })

或检查您的授权url

必须是https://yourwebsite/auth/google/callback

我的观点是: 如果使用Google_Client库，不要忘记在更新重定向URI之后更新服务器上的JSON文件。

如果你使用这个教程:https://developers.google.com/identity/sign-in/web/server-side-flow，那么你应该使用“postmessage”。

在GO中，这解决了问题:

confg = &oauth2.Config{
        RedirectURL:  "postmessage",
        ClientID:   ...,
        ClientSecret: ...,
        Scopes:      ...,
        Endpoint:     google.Endpoint,
}
