ios - 当我执行类似操作时，我收到错误消息：{"error":{"message":"(#200) Permissions error","type":"OAuthException","code":200}}

Question

我想要一个 Facebook 页面，但我收到了这个错误：

{"error":{"message":"(#200) 权限错误","type":"OAuthException","code":200}}

正如您在我的代码中看到的那样，权限似乎没问题。请注意，当我想要像 www.google.com 这样的简单 URL 时，它可以工作！

仅当我想喜欢 Facebook 页面时才收到此错误。

这是我的代码：

-(IBAction) buttonTestRecoFB
{
    NSArray *permissions = [[NSArray alloc] initWithObjects:
                            @"publish_actions",@"publish_stream",
                            nil];

    [FBSession.activeSession closeAndClearTokenInformation];

    [FBSession openActiveSessionWithPermissions:permissions allowLoginUI:YES
                              completionHandler:^(FBSession *session,
                                                  FBSessionState status,
                                                  NSError *error) {
                                  // session might now be open.
                                  [self sessionStateChanged:session state:status error:error];
                              }];
}

// FACEBOOK
//

- (void)sessionStateChanged:(FBSession *)session 
                      state:(FBSessionState) state
                      error:(NSError *)error
{
    switch (state) 
    {
        case FBSessionStateOpen: 
        {
            NSLog(@"FBSessionStateOpen");

            if (session.isOpen) 
            {
                FBRequest *me = [FBRequest requestForMe];

                [me startWithCompletionHandler: ^(FBRequestConnection *connection, 
                                                NSDictionary<FBGraphUser> *my,
                                                  NSError *error) {

                    NSLog(@"firtname = %@" , my.first_name);

                    /////////////////////////////////////////////////

                    NSString *theWholeUrl = [NSString stringWithFormat:@"https://graph.facebook.com/313449204401/likes?access_token=%@", session.accessToken];

                    NSLog(@"TheWholeUrl: %@", theWholeUrl);

                    NSURL *facebookUrl = [NSURL URLWithString:theWholeUrl];

                    NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:facebookUrl];
                    [req setHTTPMethod:@"POST"];

                    NSURLResponse *response;
                    NSError *err;
                    NSData *responseData = [NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&err];

                     NSString *content = [NSString stringWithUTF8String:[responseData bytes]];

                    NSLog(@"responseData: %@", content);
                    /////////////////////////////////////////////////                  
                }];
            }
        }

无法以编程方式将“喜欢”操作应用于 Facebook 页面。这在文档中有所说明：

对于未集成 Facebook Authentication 的 Facebook Pages 或网站，开发者应继续使用 Like 按钮社交插件。
