我的 facebook 使用 parse 登录运行良好，没有任何问题，但是生成的访问令牌没有显示好友列表的权限，尽管我在登录时给予了该权限。当我使用 facebook Graph API 'Friendlists'(fbID/friendlists) 并且响应数组为空时，我才知道。因此，还要使用生成的相同访问令牌运行 Graph API Explorer。它没有向我显示任何错误，并且数据数组是相同的空并且带有调试消息
“只有在用户授予 'read_custom_friendlists' 权限后，才能在用户对象上访问字段 'friendlists'”
这是我正在使用的方法
WLLoginViewController *login = [[WLLoginViewController alloc]init];
login.fields = PFLogInFieldsFacebook;
NSArray *permission = [[NSArray alloc]initWithObjects:@"email",@"read_custom_friendlists",@"publish_actions",@"user_location",@"user_hometown",@"user_website",@"user_about_me",@"user_photos",@"user_friends",@"read_custom_friendlists", nil];
login.facebookPermissions = permission;
WLLoginViewController 继承了 PFUserLoginManager，我从其他类调用它。
- (void)logInViewController:(PFLogInViewController *)logInController didLogInUser:(PFUser *)user {
[FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(@"permissions%@",logInController.facebookPermissions);
if(result) {
if ([result valueForKey:@"hometown"]) {
NSString *nn = [[result valueForKey:@"hometown"] valueForKey:@"name"];
[user setValue:[[result valueForKey:@"hometown"] valueForKey:@"name"] forKey:@"hometown"];
}
if ([result valueForKey:@"location"]) {
[user setValue:[[result valueForKey:@"location"] valueForKey:@"name"] forKey:@"location"];
}
[user setObject:[result valueForKey:@"id"] forKey:kWLUser_FacebookId];
[user setObject:[result valueForKey:@"name"] forKey:kWLUser_Name];
[user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if([PFInstallation currentInstallation]) {
// save in background current installation.
[[PFInstallation currentInstallation] setObject:user forKey:@"user"];
[[PFInstallation currentInstallation]saveInBackground];
}
}];
[[ParseManager sharedInstance]saveDeviceToken:[[NSUserDefaults standardUserDefaults]objectForKey:@"DeviceToken"]];
[self dismissViewControllerAnimated:YES completion:nil];
}else {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Could not login" message:@"Could not login to facebook, please try again" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
}
}];
这是当用户从 facebook 返回应用程序时正在运行的方法。代码中的 nslog 完美地显示了我给出的权限。
最后这是处理 facebook 请求的方法 -(void)handleFacebookFriendsRequest {
NSString *queryParams = @"id,name,picture.width(350).height(250),location,hometown,likes.limit(100000),statuses.limit(1),languages";
[queryParams stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@"%@",[FBSession activeSession].permissions);
NSLog(@"%@",[[FBSession activeSession].permissions description]);
NSLog(@"%@",[FBSession activeSession].accessTokenData.accessToken);
[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"me/friends?fields=%@",queryParams] completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
//change For getting everything out
NSLog(@"%@",[result objectForKey:@"data"]);
[[ApplicationDataModel sharedInstance]setFacebookFriendsList:[result objectForKey:@"data"]];
[self facebookRequestDidLoad:result];
} else {
[self facebookRequestDidFailWithError:error];
}
}];
}
我被卡住了，需要帮助。提前致谢
