强制使用Google帐户选择器 [英] Force google account chooser

问题描述

有没有一种方法可以强制 google帐户选择器出现，即使用户仅使用一个帐户登录也可以.

Is there is a way I can force the google account chooser to appear even if the user is logged in just with one account.

我已尝试通过重定向到此URL:

I have tried by redirecting to this URL:

https://accounts.google.com/AccountChooser?service=lso&continue=[authorizeurl]

它似乎可以工作，但是我不知道它是否还有其他条件可能会失败.

and it seems to work, but I don't know if there are any other conditions in which it might fail.

推荐答案

OAuth2授权URL支持以下参数:

The following parameter is supported in OAuth2 authorization URLs:

prompt

当前它可以具有值none，select_account和consent.

Currently it can have values none, select_account, and consent.

• 无:将导致Google不显示任何用户界面，因此，如果用户需要登录，则失败，如果多次登录，则选择一个帐户，如果首次批准，则同意.它可以在不可见的i框架中运行，以便在决定(例如)渲染授权按钮之前从先前授权的用户那里获取令牌.

• none: Will cause Google to not show any UI, and therefore fail if user needs to login, or select an account in case of multi-login, or consent if first approval. It can be run in an invisible i-frame to obtain a token from previously authorized users before you decide, for instance, to render an authorization button.

同意:即使用户先前已授权您的应用程序，也将强制显示批准页面.在某些特殊情况下可能会很有用，例如，如果您丢失了用户的refresh_token，因为Google仅在明确表示同意的情况下才会发出refresh_token.

consent: Will force the approval page to be displayed even if the user has previously authorized your application. May be useful in a few corner cases, for instance if you lost the refresh_token for the user, as Google only issues refresh_tokens on explicit consent action.

select_account:即使您只有一个登录用户，也将按照您的要求显示帐户选择器.

select_account: Will cause the account selector to display, even if there's a single logged-in user, just as you asked.

select_account可以与consent组合，如下所示:

select_account can be combined with consent, as in:

prompt=select_account consent
