将access_type=offline添加到授权谷歌授权URL对我来说很有用。我使用Java和Spring框架。

下面是创建客户端注册的代码:

return CommonOAuth2Provider.GOOGLE
                    .getBuilder(client)
                    .scope("openid", "profile", "email", "https://www.googleapis.com/auth/gmail.send")
                    .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                    .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth?access_type=offline")
                    .clientId(clientId)
                    .redirectUriTemplate("{baseUrl}/{action}/oauth2/code/{registrationId}")
                    .clientSecret(clientSecret)
                    .build();

这里重要的部分是授权URI，将?access_type=offline追加到该URI。

For me I was trying out CalendarSampleServlet provided by Google. After 1 hour the access_key times out and there is a redirect to a 401 page. I tried all the above options but they didn't work. Finally upon checking the source code for 'AbstractAuthorizationCodeServlet', I could see that redirection would be disabled if credentials are present, but ideally it should have checked for refresh token!=null. I added below code to CalendarSampleServlet and it worked after that. Great relief after so many hours of frustration . Thank God.

if (credential.getRefreshToken() == null) {
    AuthorizationCodeRequestUrl authorizationUrl = authFlow.newAuthorizationUrl();
    authorizationUrl.setRedirectUri(getRedirectUri(req));
    onAuthorization(req, resp, authorizationUrl);
    credential = null;
}

My solution was a bit weird..i tried every solution i found on internet and nothing. Surprisely this worked: delete the credentials.json, refresh, vinculate your app in your account again. The new credentials.json file will have the refresh token. Backup this file somewhere. Then keep using your app until the refresh token error comes again. Delete the crendetials.json file that now is only with an error message (this hapenned in my case), then paste you old credentials file in the folder, its done! Its been 1 week since ive done this and had no more problems.

使用离线访问和提示:同意对我来说很有效:

   auth2 = gapi.auth2.init({
                    client_id: '{cliend_id}' 
   });

   auth2.grantOfflineAccess({prompt:'consent'}).then(signInCallback);
