脸书好友列表

Question

我如何使用新的 facebook api 获取我的好友列表。我使用下面的代码获取了好友列表，

$friends = $facebook->api('/uid/friends');

但如果我传递他们的用户 ID，我将无法获取好友列表一样的功能..

Answer 1

你不能，那是他们的私人数据，所以它在他们的控制之下。如果他们希望应用程序能够访问它，他们会授予许可，并且应用程序可以代表他们这样做。

Answer 2

Facebook 好友列表仅获取可标记的好友列表。

Facebook 不会访问完整的个人资料好友列表，它仅显示您个人资料中的好友列表总数。

如果您应用 Facebook 开发者步骤，pod 和 plist 设置所有其他内容。

这是我在 Swift 3.0 可标记好友列表中的代码。

appdelegate.swift

import CoreData
import FBSDKCoreKit
import FBSDKLoginKit
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
         return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
        // Override point for customization after application launch.
        return true
    }
    
    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
    }
