以用户身份将照片发布到Facebook粉丝页面. iOS Facebook SDK 3.1 [英] Posting a photo to Facebook fan page as user. iOS Facebook SDK 3.1

问题描述

我正在尝试使用Facebook SDK 3.1将用户的照片发布到Facebook页面.
当我使用以下代码创建上传图片请求时:

I'm trying to post a photo to Facebook page from user using Facebook SDK 3.1.
When I'm using the following code to create upload image request:

FBRequest *uploadPhotoRequest = [FBRequest requestWithGraphPath:@"/${FAN_PAGE_ID}/photos/" parameters:[NSDictionary dictionaryWithObjectsAndKeys:self.imageToShare, @"source", nil] HTTPMethod:@"POST"];

图片直接进入用户的时间轴，而不是页面的时间轴.

Image goes directly to user's timeline, not the page's one.

但是当我发布链接时:

FBRequest *request = [FBRequest requestWithGraphPath:@"/${FAN_PAGE_ID}/feed/" parameters:[NSDictionary dictionaryWithObjectsAndKeys:@"http://stackoverflow.com", @"link", nil] HTTPMethod:@"POST"];

将帖子正确链接到Facebook页面.

Link posts correctly to the facebook page.

要打开一个会话，我正在使用代码:

To open a session I'm using code:

[FBSession openActiveSessionWithPermissions:[NSArray arrayWithObjects:@"publish_stream", @"photo_upload", nil]
                               allowLoginUI:YES
                          completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
...
                          }];

我知道openActiveSessionWithPermissions已过时，已将其用于iOS 5和6上相同的SSO行为.

I know that openActiveSessionWithPermissions is deprecated, using it for equal SSO behaviour on iOS 5 and 6.

更新

或者可以上传带有访问令牌替换的照片吗?使用页面访问令牌代替用户访问令牌.如果是，如何在不强制用户以页面管理员身份登录的情况下以编程方式获取页面访问令牌?

Or is it possible to upload a photo with access token substitution? Using page access token instead of user access token. If yes, how can I get page access token programmatically without forcing user to log in as page administrator?

您会建议我做什么?
谢谢！

What would you advise me to do?
Thanks!

推荐答案

https ://developers.facebook.com/docs/reference/api/page/#photos 说，

通过发布具有publish_stream 和manage_pages权限 […]的PAGE_ID/照片的HTTP POST请求，您可以将照片发布到Page的墙上"

"You can post photos to a Page's Wall by issuing an HTTP POST request to PAGE_ID/photos with the publish_stream and manage_pages permissions […]"

不允许像普通"用户这样的声音通过API将图像发布到页面的墙上.

Sounds like a "normal" user is not allowed to post images to a page’s wall via the API.
