JavaScript 中图形 api 调用的 access_token

发布于 2024-12-29 04:36:13 字数 141 浏览 1 评论 0原文

我正在尝试使用 JavaScript 将公共 Facebook 页面上的帖子和评论拉入并显示在我客户的网页上。我知道我需要一个 access_token，但问题是它经常过期。看来我需要动态获取 access_token 以避免这个问题。有谁知道如何在客户端执行此操作？

简短的回答：

如果页面确实是公开的，则根本不需要访问令牌。例如，

http://graph.facebook.com/19292868552
{
   "id": "19292868552",
   "name": "Facebook Platform",
   "picture": "http://profile.ak.fbcdn.net/hprofile-ak-ash2/276791_19292868552_1958181823_s.jpg",
   "link": "http://www.facebook.com/platform",
   "likes": 3922010,
   "category": "Product/service",
   "website": "http://developers.facebook.com",
   "username": "platform",
   "founded": "2007",
   "company_overview": "Facebook Platform enables anyone to build social apps on Facebook and the web.",
   "mission": "To make the web more open and social.",
   "about": "We're building the social web. Get the latest here: developers.facebook.com ",
   "talking_about_count": 74536
}

更长的答案，如果您使用特定用户的访问令牌代表他们执行操作，您可能会考虑请求“离线访问”，以便令牌不会过期。请参阅https://developers.facebook.com/docs/reference/api/permissions/< /a> 了解有关如何请求此权限的更多信息。

Short answer:

If the page is really public, you don't need an access token at all. For instance,

http://graph.facebook.com/19292868552
{
   "id": "19292868552",
   "name": "Facebook Platform",
   "picture": "http://profile.ak.fbcdn.net/hprofile-ak-ash2/276791_19292868552_1958181823_s.jpg",
   "link": "http://www.facebook.com/platform",
   "likes": 3922010,
   "category": "Product/service",
   "website": "http://developers.facebook.com",
   "username": "platform",
   "founded": "2007",
   "company_overview": "Facebook Platform enables anyone to build social apps on Facebook and the web.",
   "mission": "To make the web more open and social.",
   "about": "We're building the social web. Get the latest here: developers.facebook.com ",
   "talking_about_count": 74536
}

Longer answer, if you are using a particular user's access token to perform actions on their behalf, you might consider asking for "offline access" so that the token won't expire. See https://developers.facebook.com/docs/reference/api/permissions/ for more information about how to ask for this permission.
