Facebook Oauth访问令牌使用Graph API Explorer时不同 [英] Facebook Oauth Access Token Different when using Graph API Explorer
问题描述
（免责声明：这篇文章中的access_tokens和appIds是假的，只是意图 真实）
(Disclaimer: The access_tokens and appIds in this post are fake and are just intended to look real)
我正在尝试使用对以下内容的调用生成一个access_token：
I'm trying to generate an access_token using the call to the following:
给我这个格式的access_token：
That gives me an access_token in this format:
access_token = 123456789000000 | TR528Smvi4AXMM21Zhmi5XmJwmk
access_token=123456789000000|TR528Smvi4AXMM21Zhmi5XmJwmk
如果我尝试访问一个粉丝页面受到像这样的令牌的保护我得到假回来： http://graph.facebook.com/109813019043531 ？=的access_token 1234567.89亿| TR528Smvi4AXMM21Zhmi 5XmJwmk
If I try to access a fan page that's protected with that token like this I get false back: http://graph.facebook.com/109813019043531?access_token=123456789000000|TR528Smvi4AXMM21Zhmi5XmJwmk
现在，如果我使用Graph API Explorer并选择与上面使用的App一样的App来生成访问令牌，我得到一个访问令牌如下所示：
Now, if I use the Graph API Explorer and select the same App as the one I'm using above to generate the access token I get an access token that looks like this:
ABBDSqE43jFSSbrS7ujvyLZClfyKDCZBhAuLXTtr9nwelj4MFwlijzejljEoNItC3lijzj3jgj3jDFCdAZD
ABBDSqE43jFSSbrS7ujvyLZClfyKDCZBhAuLXTtr9nwelj4MFwlijzejljEoNItC3lijzm3shemzq3jDFCdAZD
如果我使用该访问令牌来访问URL ：//graph.facebook.com/109813019043531）它按预期工作。
If I use that access token to access the URL (http://graph.facebook.com/109813019043531) it works as expected.
我的问题是，两者之间有什么区别，我如何以编程方式生成一个像第二个令牌一样工作？
My question is, what is the difference between the two and how can I programmatically generate one that works like the second token?
推荐答案
您显示的第一个是一个APP访问令牌。 Graph API Explorer中的第二个是USER访问令牌。第三种类型称为PAGE访问令牌。每个人都做不同的事情
The first one you show is an APP access token. The second one from Graph API Explorer is a USER access token. There is a third type called PAGE access token. Each do something different.
APP访问令牌用于获取您的应用有权访问的信息。而在某些情况下，从应用程序用户授予publish_stream，您可以使用它发布到该用户的墙壁，而不需要使用USER访问令牌。
APP access tokens are used to get information that your app is privileged to access. And in some cases where publish_stream is granted from an app user, you can use it to post to that user's wall, without needing a USER access token.
USER访问令牌被赋予您的应用，它们与特定应用用户授予您的应用的权限相关，因此您的应用可以代表您执行。
USER access tokens are given to your app and they relate to the permissions a specific app user has granted to your application so you app can act on their behalf.
PAGE访问令牌被提供给页面管理员，以便他们可以代表页面进行操作。要从用户访问令牌转到页面访问令牌，请使用用户访问令牌来调用 / me / accounts ，以获取他们管理的页面列表以及每个页面访问令牌。
PAGE access tokens are given to page admins so they can act on behalf of the page. To go from a user access token to a page access token, call /me/accounts using the user access token to get a list of pages they admin along with each pages access tokens.
