我想喜歡一個Facebook頁面，但我得到這個錯誤：我收到了錯誤消息：{「error」：{「message」：「（＃200）Permissions error」，「type」：「OAuthException」，「code」：200}}當我做一個類似的動作

{"error":{"message":"(#200) Permissions error","type":"OAuthException","code":200}}

正如你可以在我的代碼中看到，權限似乎是確定。請注意，當我想要喜歡諸如www.google.com這樣的簡單網址時，它可以正常工作！

只有當我想要喜歡Facebook頁面時，纔得到此錯誤。

這裏是我的代碼：

-(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); 
        /////////////////////////////////////////////////     
       }]; 
      } 
     }
