问题描述

据我所知，最近 Facebook 决定删除 offline_access 权限，并引入了一个称为长寿命访问令牌的概念，最长持续时间为 60 天.有没有人知道如何使用 Facebook JavaScript SDK 获取此访问令牌?

As I understand it, recently Facebook has decided to remove the offline_access permission and has introduced a concept called long-lived access tokens which last a maximum of 60 days. Is there anyone who knows how to get this access token with the Facebook JavaScript SDK?

推荐答案

有一种方法可以将此期限延长至 60 天.此处描述:https://developers.facebook.com/docs/roadmap/completed-更改/离线访问删除/场景 4:客户端 OAuth 和通过新端点延长 Access_Token 过期时间

There is a way to extend this to 60 days. described here: https://developers.facebook.com/docs/roadmap/completed-changes/offline-access-removal/under Scenario 4: Client-side OAuth and Extending Access_Token Expiration Time through New Endpoint

为了扩展访问令牌，您需要使用短期访问令牌发出以下请求:

In order to extend the access token you need to make the following request with your short lived access token:

https://graph.facebook.com/oauth/access_token?
    client_id=APP_ID&
    client_secret=APP_SECRET&
    grant_type=fb_exchange_token&
    fb_exchange_token=EXISTING_ACCESS_TOKEN
