如何将照片上传到Facebook页面的时间表作为Facebook页面本身，而不是用户Feed [英] How to Upload a Photo to a Facebook Page's Timeline as the Facebook Page itself, Not to the user feed
问题描述
确定所以鳕鱼以下基本上都可以正常工作，WHEN这行是这样的：
$ post_url ='/'.$userPageId.'/feed';
成功发布到Facebook页面时间轴。但是我想上传一张照片，当我将这行更改为
$ post_url =' /'.$userPageId.'/photos';
它发布照片...但它发布到用户Feed，而不是AS的Facebook页面。
我想要将照片发布到Facebook页面时间轴

如果您要作为Facebook页面并上传一张照片，您需要：
- 成为Facebook页面上的管理员
- 获得授权时至少有以下范围：'manage_pages'，'photo_upload'
- 访问令牌作为Facebook页面，而不是作为管理员的用户
您可以通过调用 Open Graph API ：
$ accounts = $ facebook-> api（'/ me / accounts'，'GET'）;
为了获取访问令牌和任何更多信息，您需要manage_pages权限。 / p>
一旦拥有访问令牌，您将需要使用它并重新初始化客户端。那么你可以基本上像它一样行事，并张贴一张照片。希望这将足以让你开始。您的代码看起来设置为能够将照片上传到您想要的位置。这是所有访问令牌的问题。
编辑：
您可以使用PHP设置访问令牌SDK与 setAccessToken ：
//设置一个新的访问令牌，首先通过SDK以外的方式获取它
$ facebook-> setAccessToken（$ new_access_token）;
OK so the cod below basically works fine, WHEN this line is like this:
$post_url = '/'.$userPageId.'/feed';
This successfully posts to the Facebook Page Timeline. But I want to upload a photo, and when I change this line to
$post_url = '/'.$userPageId.'/photos';
It posts the photo... but it posts to the User Feed, instead of AS the Facebook Page.
I want this to post the photo to the Facebook Page Timeline

If you want to act as the Facebook Page and upload a photo as such, you'll need:
- To be an Admin on the Facebook Page
- At least the following scopes when getting authorizations: 'manage_pages', 'photo_upload'
- The access token as the Facebook Page, NOT as the User who is the Admin
You can fetch the access tokens of the Facebook Pages you are Admin of by calling the Open Graph API:
$accounts = $facebook->api('/me/accounts','GET');
In order to get the access token and any more information, you need the 'manage_pages' permission.
Once you have the access token, you'll need to use it and re-initialize a client with it. Then you can essentially act as it, and post a photo as it. Hopefully this will be enough to get you started. Your code looks set up to be able to upload the photo to where you want it to be. It's all a matter of the access token.
Edit:
You can set the access token with the PHP SDK with setAccessToken:
// Set a new access token, by first getting it via means other than the SDK
$facebook->setAccessToken($new_access_token);
