我想从谷歌获取访问令牌。谷歌API说，要获得访问令牌，将代码和其他参数发送到令牌生成页面，响应将是一个JSON对象，如:
{
"access_token" : "ya29.AHES6ZTtm7SuokEB-RGtbBty9IIlNiP9-eNMMQKtXdMP3sfjL1Fc",
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : "1/HKSmLFXzqP0leUihZp2xUt3-5wkU7Gmu2Os_eBnzw74"
}
但是，我没有收到刷新令牌。我的回答是:
{
"access_token" : "ya29.sddsdsdsdsds_h9v_nF0IR7XcwDK8XFB2EbvtxmgvB-4oZ8oU",
"token_type" : "Bearer",
"expires_in" : 3600
}

我找了一个漫长的夜晚，这个很管用:
修改了admin-sdk中的user-example.php
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$authUrl = $client->createAuthUrl();
echo "<a class='login' href='" . $authUrl . "'>Connect Me!</a>";
然后在重定向url处获得代码 用代码进行身份验证并获得刷新令牌
$client()->authenticate($_GET['code']);
echo $client()->getRefreshToken();
你现在应该把它存储;)
当你的accesskey超时就做
$client->refreshToken($theRefreshTokenYouHadStored);
其他回答
为了在每次验证时获得新的refresh_token，在仪表板中创建的OAuth 2.0凭据类型应该是“Other”。同样如上所述，在生成authURL时应该使用access_type='offline'选项。
当使用类型为“Web application”的凭据时，prompt/approval_prompt变量的组合将不起作用——您仍然只能在第一个请求上获得refresh_token。
这给我带来了一些困惑，所以我想分享一下我艰难的经历:
当您使用access_type=offline和approval_prompt=force参数请求访问时，您应该收到一个访问令牌和一个刷新令牌。访问令牌在收到后不久就会过期，您需要刷新它。
您正确地发出了获取新访问令牌的请求，并收到了具有新访问令牌的响应。我还对没有获得新的刷新令牌感到困惑。然而，这就是它的意义所在，因为您可以反复使用相同的刷新令牌。
我认为其他一些答案假设您出于某种原因想要获得一个新的刷新令牌，并建议您重新授权用户，但实际上，您不需要这样做，因为您拥有的刷新令牌将一直工作，直到用户撤销。
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.

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;
}
