嵌入公开Facebook页面的活动Feed，而不强制用户登录/允许 [英] Embed activity feed of a public Facebook page without forcing user to login/allow

问题描述

这与以前提问的问题类似，不过不管我读什么，我还是很困惑。

我有一个公开的Facebook页面，如白领域例如，其活动Feed需要嵌入到我的Android应用程序中。我了解如何获取应用程序和应用程序秘密，但我不明白如何获取短命令访问令牌，我明白是获取长期访问令牌所必需的。

根据我的理解，这可能是错误的，用户必须通过应用登录才能获得一个短暂的访问令牌，但我不想任何用户必须登录才能查看活动信息。

一旦这样，我该如何使用它将此活动Feed引入我的应用程序？

这个Facebook的文档很糟糕，所以我需要一些帮助。

如果它或任何其他需要站点特定的权限，我可以访问有关的网站。

谢谢！

解决方案

要获取公开Facebook页面（如白领）的活动信息，请按照下列步骤操作：

1）通过选择现有应用程序或在此网址创建新应用程序，获取您的App-id和App-secret：

  https://developers.facebook.com/apps/ 
  

2）通过向该URL发出GET请求获取访问令牌：

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

3）获取您的粉丝页面的页面ID。为此，您需要页面名称。转到你的粉丝页面，看看网址。它将具有以下形式：

  https://www.facebook.com/ {fan-page-name} 
  

一旦这样做，请向此网址发出GET请求：

  https://graph.facebook.com/ {fan-page-name}？access_token = {access-token} 
  / pre> 
 
 
它将返回一堆JSON。您正在寻找第一个id元素。这是您的页面ID。
 
 
 
 4）获取粉丝专页JSON数据，并向该网址发送GET请求：
  https://graph.facebook.com/+ page-id +/ feed？access_token =+ URLEncoder.encodeUTF8（access-token）
  
为避免出现异常，我不得不使用 URLEncoder.encodeUTF8（）。 
您正在查找的数据位于data元素下。
 
 
 
我无法找到任何可以进行JSON解析的内容的Facebook Feed，但我确实发现这个教程将会为您做很多格式，使其看起来像Facebook。
 
 
 
希望帮助任何人尝试这样做。
 
This is similar to questions asked several times before, but no matter what I read, I'm still confused.

I have a public Facebook page, like White Collar for example, whose activity feed I need to embed into my Android app. I understand how to get the app-id and app-secret, but I don't understand how to get the short-lived access token, which I understand is necessary to get a long-lived access token. 

From what I understand, which can quite possibly be wrong, the user has to login through the app to get a short-lived access token, but I don't want any user to have to login to view the activity feed.

Once I have that, how do I then use it to bring this activity feed into my app?

The Facebook documentation for this is terrible so I need some help. 

If it or anything else requires site-specific permissions, I have access to the site in question.

Thanks!
解决方案
To get the activity feed of a public Facebook page, like White Collar, follow these steps:

1) Get your App-id and App-secret by choosing an existing app or creating a new one at this url:
https://developers.facebook.com/apps/
2) Get an access token by making a GET request to this url:
https://graph.facebook.com/oauth/access_token?client_id=" + APP_ID + "&client_secret=" + APP_SECRET + "&grant_type=client_credentials
3) Get the page-id of your fan page. To do this, you need the page-name. Go to your fan page on facebook and look at the url. It will have this form:
https://www.facebook.com/{fan-page-name}
Once you have that, make a GET request to this url:
https://graph.facebook.com/{fan-page-name}?access_token={access-token}
It will return a bunch of JSON. You're looking for the first "id" element. This is your page-id.

4) Get the fan page JSON data with a GET request to this url:
https://graph.facebook.com/" + page-id + "/feed?access_token=" + URLEncoder.encodeUTF8(access-token)
To avoid having exceptions thrown, I had to use URLEncoder.encodeUTF8().
The data you're looking for is under the "data" element.

I wasn't able to find anything that would do the JSON parsing of the Facebook feed for me, but I did find this tutorial that will do a lot of the formatting for you to make it look like Facebook.

Hope that helps anyone else trying to do this.
