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
}

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.

我想为那些遇到这个问题的沮丧灵魂补充一点关于这个主题的信息。获得离线应用程序刷新令牌的关键是确保呈现同意屏幕。refresh_token仅在用户通过单击“允许”授予授权后立即返回。
在我在开发环境中进行了一些测试之后，我(我怀疑还有许多其他人)就遇到了这个问题，因此我已经在一个给定的帐户上授权了我的应用程序。然后，我转移到生产环境，尝试使用一个已经获得授权的帐户再次进行身份验证。在这种情况下，同意屏幕不会再次出现，api也不会返回新的刷新令牌。要实现此功能，您必须通过以下方式强制再次出现同意屏幕:
prompt=consent
or
approval_prompt=force
任何一个都可以，但你不应该同时使用。截至2021年，我建议使用prompt=consent，因为它取代了旧的参数approval_prompt，在一些api版本中，后者实际上已经被破坏了(https://github.com/googleapis/oauth2client/issues/453)。此外，prompt是一个以空格分隔的列表，因此如果您想要两者都使用，可以将其设置为prompt=select_account%20consent。
当然你还需要:
access_type=offline

在我意识到添加access_type=offline是在前端客户端对授权代码的请求上完成的，而不是在将该代码交换为access_token的后端请求上完成的之后，Rich Sutton的回答终于对我有用了。我给他的回答加上了一条评论，并在谷歌上添加了这个链接，以获取有关刷新令牌的更多信息。
注:如果你正在使用Satellizer，下面是如何将该选项添加到$authProvider。AngularJS中的谷歌。
要使用postman获取刷新令牌，下面是一个配置示例
预期响应
1. 如何获得'refresh_token' ?
解决方案:access_type='offline'选项应该在生成authURL时使用。 来源:为Web服务器应用程序使用OAuth 2.0
2. 但即使有'access_type=offline'，我没有得到'refresh_token' ?
解决方案:请注意，您只会在第一次请求时获得它，所以如果您将它存储在某个地方，并且在您的代码中有一个条款可以在上次过期后获得新的access_token时覆盖它，那么请确保不要覆盖这个值。
From谷歌Auth Doc:(this value = access_type)
该值指示谷歌授权服务器返回一个 刷新令牌和访问令牌，第一次您的应用程序 将授权代码交换为令牌。
如果你再次需要'refresh_token'，那么你需要按照Rich Sutton的回答中所写的步骤删除对应用程序的访问。
