Post to Facebook Page wall using RestFB api
提问by Alvin
I am trying to post on the wall of a facebook page. I am able to post on the user wall using App Access token.
我正在尝试在 facebook 页面的墙上张贴。我可以使用 App Access 令牌在用户墙上发帖。
I got the App Access Token through extending the DefaultFacebookClient
我通过扩展 DefaultFacebookClient 获得了应用程序访问令牌
public class ConnectionService extends DefaultFacebookClient{
public ConnectionService(String appId, String appSecret) {
AccessToken accessToken = this.obtainAppAccessToken(appId, appSecret);
this.accessToken = accessToken.getAccessToken();
}
}
With this I am able to post to user wall using the appID and appSecret. But when I tried to post to Page Wall i get error of " The user hasn't authorized the application to perform this action"
有了这个，我可以使用 appID 和 appSecret 发布到用户墙。但是当我尝试发布到页面墙时，我收到错误消息“用户尚未授权应用程序执行此操作”
Anyone can advice?
任何人都可以建议？

The App Access Token is the most basic one, and will not allow you to post anything. In order to post something to a Facebook Page (as a Page), you need to get a Page Access Token.
App Access Token 是最基本的，不允许您发布任何内容。为了向 Facebook 主页发布内容（作为主页），您需要获取主页访问令牌。
The process is a bit complicated, because you actually need to authorize the user with the "manage_pages" permission first, with the User Access Token you can call the API to get a Page Access Token (/me/accounts).
这个过程有点复杂，因为你实际上需要先给用户授权“manage_pages”权限，有了User Access Token就可以调用API获取Page Access Token（/me/accounts）。

Btw, the REST API is deprecated: https://developers.facebook.com/blog/post/616/
顺便说一句，REST API 已弃用：https: //developers.facebook.com/blog/post/616/
You can also try the "Client Token" (Developer Settings > Advanced), i never worked with that one but it could be the easiest solution. In any case, an App Access Token is the wrong one.
您还可以尝试“客户端令牌”（开发人员设置 > 高级），我从未使用过该令牌，但它可能是最简单的解决方案。在任何情况下，应用程序访问令牌都是错误的。

Since u r generating access token from java class. u can set the permissions u require from user in ur manage app link from ur facebook profile page and get the access token here.....
因为你是从java类生成访问令牌的。您可以在您的 Facebook 个人资料页面的管理应用程序链接中设置您需要的用户权限，并在此处获取访问令牌.....

To post on a facebook page wall, you will need to follow these steps:
要在 Facebook 页面墙上发帖，您需要按照以下步骤操作：
- Head over to https://developers.facebook.com/tools/explorer
- Click on "Get Access Token"
- Under "Extended Permissions" tab, select select manage_pages and publish_actions and hit "Get Access Token"
- Now under Graph API, under Get call, type in "me/accounts" and hit Submit
- In the screen below, you will see the "data" json object with all your pages and page access tokens.
- Grab the desired page token access and replace the PAGE_ACCESS_TOKEN in the code below with this token.
- Replace PAGE_NAME with your page name (the page name slug in the URL).
- Run the below code and that should do the job :)
- 前往https://developers.facebook.com/tools/explorer
- 点击“获取访问令牌”
- 在“扩展权限”选项卡下，选择 manage_pages 和 publish_actions 并点击“获取访问令牌”
- 现在在 Graph API 下的 Get call 下，输入“me/accounts”并点击 Submit
- 在下面的屏幕中，您将看到包含所有页面和页面访问令牌的“数据”json 对象。
- 获取所需的页面令牌访问权限并将下面代码中的 PAGE_ACCESS_TOKEN 替换为此令牌。
- 将 PAGE_NAME 替换为您的页面名称（URL 中的页面名称）。
- 运行下面的代码，这应该可以完成工作:)
final FacebookClient fb = new DefaultFacebookClient(PAGE_ACCESS_TOKEN);
final Page page = facebookClient.fetchObject(PAGE_NAME, Page.class);
facebookClient.publish("PAGE_NAME/feed", FacebookType.class, Parameter.with("message", "RestFB test"));
final FacebookClient fb = new DefaultFacebookClient(PAGE_ACCESS_TOKEN);
final Page page = facebookClient.fetchObject(PAGE_NAME, Page.class);
facebookClient.publish("PAGE_NAME/feed", FacebookType.class, Parameter.with("message", "RestFB test"));
