Swift FBSDK图形请求 - 必须使用活动访问令牌

Question

只有在我升级到xCode 9之后才开始出现此错误。在此之前，我从未遇到过这个问题，并且没有任何更改。当我发出图形请求时，我收到以下错误：

- some: Error Domain=com.facebook.sdk.core Code=8 "(null)" UserInfo={com.facebook.sdk:FBSDKGraphRequestErrorCategoryKey=0, com.facebook.sdk:FBSDKGraphRequestErrorHTTPStatusCodeKey=400, com.facebook.sdk:FBSDKErrorDeveloperMessageKey=An active access token must be used to query information about the current user., com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500, com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={
    body =     {
        error =         {
            code = 2500;
            "fbtrace_id" = HV5mzgqALtD;
            message = "An active access token must be used to query information about the current user.";
            type = OAuthException;
        };
    };
    code = 400;
}} #0

我不确定为什么我会收到有关访问代码的错误，我确实包含它，之前不是问题，它已经传递给Firebase了。我已经更新了所有的pod，尝试清理构建，仔细检查了我的Facebook开发帐户，在xCode中仔细检查了FBSDK的配置，我能想到的一切。

这是我的图表请求：

func fetchFacebookInfoForFirstTimeUser(_ firebaseUser:User) {
        print("fetchFacebookInfoForFirstTimeUser")


        let params = ["fields": "education, name, first_name, last_name, birthday, email, gender, locale, timezone, work, picture.type(large)"]
        let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: params)

        _ = graphRequest?.start { [weak self] connection, result, error in
            guard let weakSelf = self else { return }

            // If something went wrong, we're logged out
            if (error != nil) {
                dump(error)
                return
            }
            // Whole bunch of stuff processing the data
    }
}

以下是用于登录Facebook和Firebase的所有代码：

/* ------------------ FACEBOOK -------------------- */

    @objc func handleCustomFBLogin() {
        let permissions = ["public_profile", "email", "user_birthday", "user_location", "user_education_history", "user_work_history", "user_friends"]
        FBSDKLoginManager().logIn(withReadPermissions: permissions, from: self) {
            (result, err) in
                if err != nil {
                    print("FB Login Failed:", err!)
                    return
                } else {
                    print("FB Login Success!")

                    self.connectToFirebase()
                    Util.showLoadingIcon(uiView: self.view)
                }
        }
    }

    /* ------------------ FIREBASE ------------------ */
    /* --------------------------------------------- */
    func connectToFirebase() {
        print("connecting to Firebase")
        let accessToken = FBSDKAccessToken.current()
        guard let accessTokenString = accessToken?.tokenString else { return }
        let credentials = FacebookAuthProvider.credential(withAccessToken: accessTokenString)

        Auth.auth().signIn(with: credentials, completion: { (user, error) in
            // Auth.auth().signIn(withEmail: "test@gmail.com", password: "111111", completion: { (user, error) in
            if error != nil {
                print("Something went wrong with our FB user:", error ?? "" )
                return
            }

            // Update FCM TOKEN
            var token = "A1"
            if let t = InstanceID.instanceID().token(){
                token = t
            }
            print("fcmToken: \(token)")
            let l = Database.database().reference(withPath: "users/\(user!.uid)")
            l.updateChildValues(["fcmToken": token])

            // Successfully logged in, let's move on
            print("Successfully logged into Firebase!")
            self.configureAppForUser(curUser: user!)
            print(user!.uid)
        })
    }

    func configureAppForUser(curUser: User) {
        // Grab the current user's data
       // self.pushDashboardViewController()
        print("configureAppForUser")
        ref.child("users").child(curUser.uid).observeSingleEvent(of: .value, with: { (snapshot) in
            if snapshot.value is NSNull {
                print("First time user")
                // User does not have any data in Firebase, so get FB data and show onboarding
                self.fetchFacebookInfoForFirstTimeUser(curUser)
            } else {
                print("Existing user")
                let json = JSON(snapshot.value!)
                if json["onboarded"] == JSON.null || json["onboarded"] == false {
                     print("User has NOT onboarded")
                    // User has not onboarded, show onboarding screen
                    self.fetchFacebookInfoForFirstTimeUser(curUser)
                } else {
                    print("User HAS onboarded")
                    // User HAS onboarded, go to home screen
                    UserDefaults.standard.set(true, forKey: "KnownUser\(String(describing: curUser.uid))")

                    self.pushDashboardViewController()
                }
            }
        }) { (error) in
