如何通过code得到页访问令牌？ [英] How to get Page Access Token by code?

问题描述

我需要生成一个页面访问令牌，我，此令牌将被网页所张贴到其Facebook页面饲料的网页。

I need to generate a Page Access Token for a webpage that I have, this token will be used by the webpage to post to its Facebook Page feed.

这是我做的：

1. 转至图形API资源管理器


2. 从下拉列表中选择我的应用程序


3. 点击获得访问令牌


4. 选择正确的权限（ manage_pages / user_events ）

1. Go to Graph API Explorer
2. Choose my app from the dropdown
3. Click Get Access Token
4. Choose correct permissions(manage_pages/user_events)

要获得网​​页访问令牌我要运行我/帐户在图形API浏览器。这将显示我一个新的页面访问令牌（短暂（约60分钟））得到了所有页面每一个。

To get the Page Access Token I have to run me/accounts in the Graph API Explorer. This will show all the pages I got with a new Page Access Token (short lived(about 60 min)) to each one.

本页面访问令牌将工作只是罚款在我的C＃code使用张贴到饲料中。

This Page Access Token will work just fine to use in my C# code to post to the feed.

问题

当另一个用户使用我的网页上张贴文章，我需要生成一个新的网​​页访问令牌（在code），然后用它来发布userpost到site's Facebook的饲料。问题是，我可以清楚地没能亲自授予的帖子让我怎么处理呢？

When another user uses my webpage to post a post I need to generate a new Page Access Token(in code) and then use it to post the userpost to the site´s facebook feed. The problem is that I could clearly not be there to grant the post so how do I handle this?

我显然不能运行我/帐户（在code）命令来获得网​​页访问令牌从这里开始。

I could obviously not run the me/accounts(in code) command to get the Page Access Token from here.

我已经看过延长访问令牌，但这将持续60天，那么这将是同样的问题如上。

I have looked at extended Access Token but this will last 60 days and then it will be the same problem as above.

推荐答案

您需要的是一个扩展页令牌：

What you need is an Extended Page Token:

• 生成用户访问令牌与 manage_pages 和 publish_actions


• 生成扩展用户令牌（有效期60天）：<一href=\"https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=[app-id]&client_secret=[app-secret]&fb_exchange_token=[short-lived-token]\">https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=[app-id]&client_secret=[app-secret]&fb_exchange_token=[short-lived-token]


• 通话 / ME /帐户通过扩展用户令牌得到扩展页令牌

• generate User Access Token with manage_pages and publish_actions
• generate Extended User Token (valid for 60 days): https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=[app-id]&client_secret=[app-secret]&fb_exchange_token=[short-lived-token]
• call /me/accounts with the Extended User Token to get Extended Page Tokens

扩展页令牌是永远有效，所以你鸵鸟政策需要生成一个新的所有的时间。

Extended Page Tokens are valid forever, so you don´t need to generate a new one all the time.
