Ios 在Swift中获取google日历事件时获取N错误域：“com.google.GTLJSONRPCErrorDomain”

我正在尝试将日历事件提取到iOS应用程序。为此，我在Google开发者控制台中创建了一个项目，并获得了客户端ID ApiKey

并安装了带有

在登录Gmail后，它会请求访问日历的权限，直到工作正常，但是，在获取显示以下错误的事件时

error   NSError domain: "com.google.GTLJSONRPCErrorDomain" - code: 401  0x0000604000646330

我的代码如下

private let scopes = [kGTLAuthScopeCalendar]

private let service = GTLServiceCalendar()

private let kApiKey = "someKey"

let output = UITextView()

private let kKeychainItemName = "Google Calendar API"

private let kClientID = "SomeID"

func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {

    if (error == nil) {


    } else {
        print("\(error.localizedDescription)")
    }

    if user != nil {
        output.frame = view.bounds
        output.isEditable = false
        output.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 20, right: 0)
        output.autoresizingMask = [.flexibleHeight, .flexibleWidth]

        view.addSubview(output);

        if let auth = GTMOAuth2ViewControllerTouch.authForGoogleFromKeychain(
            forName: kKeychainItemName,
            clientID: kClientID,
            clientSecret: nil) {
            service.authorizer = auth
        }

        print("\(user)")
        service.authorizer = user.authentication.fetcherAuthorizer()
        fetchEvents()
    }

}

func fetchEvents() {

    let query = GTLQueryCalendar.queryForEventsList(withCalendarId: "primary")

    query?.maxResults = 10
    query?.singleEvents = true
    query?.orderBy = kGTLCalendarOrderByStartTime
    service.executeQuery(
        (query)!,
        delegate: self,
        didFinish: #selector(displayResultWithTicket(ticket:finishedWithObject:error:)))
}

// Display the start dates and event summaries in the UITextView

@objc func displayResultWithTicket(

    ticket: GTLServiceTicket,
    finishedWithObject response : GTLCalendarEvents,
    error : NSError?) {

    if let error = error {
        showAlert(title: "Error", message: error.localizedDescription)
        return
    }

    var eventString = ""

    if let events = response.items(), !events.isEmpty {
        for event in events as! [GTLCalendarEvent] {
            print(event)
        }
    } else {
    print("No upcoming events found.")
  }
}

   func showAlert(title: String, message: String) {

    let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
    alert.addAction(UIAlertAction(title: "Thank You", style: UIAlertActionStyle.default, handler: nil))
    self.present(alert, animated: true, completion: nil)

    }    

override func viewDidLoad() {
    super.viewDidLoad()

    GIDSignIn.sharedInstance().clientID = kClientID
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().scopes = scopes
    GIDSignIn.sharedInstance().signIn()
    GIDSignIn.sharedInstance().delegate = self
    service.apiKey = kApiKey
}

即使我检查了几个论坛，我也没有得到任何解决方案

谁能告诉我哪里出错了

Swift-4

我不明白你为什么会犯这样的错误。 我认为您没有使用最新的播客。 参考下面的代码，这是我用来获取google日历事件的代码

那么，这些是正确的吗？Demp应用程序pod“GTMOAuth2”、“1.1.0”pod“Google/SignIn”、“3.0.3”pod“GoogleApiclientForest/Calendar”、“1.2.1”的pod和我在developer.Google控制台网站中只启用了Gmail和Calendar。好吗？我在pod安装后没有收到这样的模块“GoogleAppClient错误”，请清理您的项目，然后重试。尝试过，甚至重新安装pod。但是，同样的问题也在发生。
