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。

重定向URI(返回响应的地方)必须在api控制台中注册，错误指示您没有这样做，或者没有正确地这样做。

转到项目的控制台，在API Access下查看。您应该在那里看到您的客户端ID和客户端秘密，以及一个重定向uri列表。如果您想要的URI没有列出，单击编辑设置并将URI添加到列表中。

编辑:(来自下面评价很高的评论)请注意，更新谷歌api控制台和当前的更改可能需要一些时间。通常只有几分钟，但有时似乎更长。

2015年7月15日-上周在登录时使用这个脚本工作的登录

<script src="https://apis.google.com/js/platform.js" async defer></script>

停止工作并开始导致Error 400 with Error: redirect_uri_mismatch

然后在DETAILS部分:redirect_uri=storagerelay://…

我把它改成:

<script src="https://apis.google.com/js/client:platform.js?onload=startApp"></script>

I had this problem using Meteor and Ngrok, while trying to login with Google. I put the Ngrok URL in the Google Developer Console as redirect URLs, and went to the Ngrok URL page. The thing was that I didn't use Meteor's ROOT_URL when executing the app, so any redirect would go to localhost:3000 insted of the Ngrok URL. Just fixed it by adding the Ngrok URL as ROOT_URL on Meteor's configuration or by exporting it before executing the app on the terminal like: export ROOT_URL=https://my_ngrok_url

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

检查表:

HTTP还是https? &或&? 后面的斜杠(/)还是打开? (CMD/CTRL)+F，在证书页面中搜索精确匹配。如果 没有找到，那就去找失踪的那个。 等待谷歌刷新它。可能每半小时发生一次，如果你 经常更换，否则可能会留在池中。就我的情况而言，几乎用了半个小时才生效。
