Question

下午好！我需要从Facebook获取用户数据。我成功获取了用户名，ID，照片等数据。但是当你尝试查询婚姻状况时，我得到一个空字典的回复。我尝试提出不同的请求，但总是得到这样的结果。我还阅读了这些主题official Facebook site，this，this，如何解决此问题？

我的示例代码

   static func getUserRelationship() {
    if (FBSDKAccessToken.currentAccessToken() != nil) {
        guard let currentUser = getCurrentFacebookUser() else { return }
        FBSDKGraphRequest(graphPath: "/\(currentUser.id)/family", parameters: nil, HTTPMethod: "GET").startWithCompletionHandler({ (requestConnection, result, error) in
            if error == nil {
                let dictionary = result as! [String : AnyObject]
                let array = dictionary["data"]
                print("facebook", result, dictionary, array?.count)
            } else {
                print(error.localizedDescription)
            }
        })
    } else {
        getDataLogin({
            getUserBirthday()
            }, fails: { (error) in

        })
    }
}

我在控制台中看到了结果

    facebook {
    data =     (
    );
}

您的GraphRequest不正确。如果你想获取用户数据，graphPathe应该是“我”，你应该请求参数以获得关系状态和其他信息。而且你需要在LogInWithReadPermissons中请求公开的个人资料，所以在阅读许可： -

    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    fbLoginManager.loginBehavior = FBSDKLoginBehavior.Web
    fbLoginManager.logInWithReadPermissions(["public_profile","email"], fromViewController: self) { (result, error) -> Void in
        if error != nil {
            print(error.localizedDescription)
            self.dismissViewControllerAnimated(true, completion: nil)
        } else if result.isCancelled {
            print("Cancelled")
            self.dismissViewControllerAnimated(true, completion: nil)
        } else {

        }
    }

检索信息时： -

   FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, relationship_status"]).startWithCompletionHandler({ (connection, result, error) -> Void in
            if (error == nil){
                let fbDetails = result as! NSDictionary
                print(fbDetails)
            }
        })

顺便说一下，如果你想要婚姻状况，你应该使用graphPath作为“我”而不是“/ {user-id} / family”。你可以用它来获得这个人的家庭关系。
