在Facebook上自动发布(代表用户)

问题描述

我一直在搜索，但没有找到答案.我有一个提供实时跟踪服务的网站.我已经使用了javascript facebook共享供稿，以便用户可以在其Facebook页面上发布其活动和其他活动.

I've been searching and haven't found an answer.I've a website that has a livetracking service.I already use the javascript facebook share feed so that users can post on their facebook page their and others activities.

我想知道目前是否可以代表用户发布(我知道过去是可能的).我已经有一个获取长命令牌的过程.

I wonder is at the moment (I know it had been possible in the past) is possible to post on user behalf. I already have a process to get a long lived token.

目标是在用户开始/结束活动时提供自动发布的功能，通知其关注者.

The goal is to give the ability of auto post when users start/end activities, informing their followers.

推荐答案

自2018年8月起更新:

publish_actions不能再使用.无法再自动将内容发布在用户的个人资料上. Facebook建议改为使用share dialog，这需要用户确认每个帖子. Facebook将向用户显示一个窗口以批准该帖子.
使用share dialog:

The publish_actions can not be used anymore. It is not possible to post content on a user's profile automatically anymore. Facebook suggests using the share dialog instead, which requires the user's confirmation for every post. Facebook will show a window to the user for approving the post.
Example code for using the share dialog:

FB.ui({
  method: 'share',
  href: 'https://developers.facebook.com/docs/',
}, function(response){});

包含所有参数的完整文档可以在这里找到: https://developers.facebook.com/docs/sharing/reference/share-对话框

只有在该用户已授予其发布权限的情况下，第三方才能代表该用户发布内容.

A third party is only able to post content on behalf of a user if that user has granted permission for doing so.

第一步是注册一个应用程序，以防您尚未注册它: https://developers.facebook.com/apps/

The first step is to register an app, in case you haven't done it already:https://developers.facebook.com/apps/

Facebook将向用户显示提示，并要求他向该应用程序授予权限.在Facebook应用程序中，您需要请求publish_actions权限.这将为您提供访问令牌，以该用户的名字在该用户的墙上发布帖子.

Facebook will show a prompt to the user and ask him for giving permissions to that app. In the Facebook app, you need to ask for publish_actions permissions.This will give you an access-token to publish posts on the wall of that user in his name.

为此，您可以使用Graph API:

For doing so you could use the Graph API:

POST graph.facebook.com
     /{user-id}/feed?
     message={message}&
     access_token={access-token}

如果您使用的是JavaScript SDK，则代码可能类似于以下内容:

If you are using the JavaScript SDK, the code could look similar to this:

FB.init({
    appId: 'insert your appID value here',
    cookie: true,
    xfbml: true,
    status: true });

FB.api(
    "/{user-id}/feed",
    "POST",
    {
        "message": "This is a test message"
    },
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);
