在swift中获取google日历事件时获取nserror域:“com.google.gtljsonrpcerrordomain”

google-authentication google-calendar-api calendar swift ios

Anilkumar iOS Developer · 技术社区 · 6 年前

我正在尝试将日历事件提取到我的ios应用程序中。为此,我在google developers控制台中创建了一个项目,得到了客户端id,apikey。

和安装的吊舱

pod 'GoogleAPIClient/Calendar', '~> 1.0.2'
pod 'GTMOAuth2', '~> 1.1.0'
pod 'Google/SignIn'

而在登录gmail后,其请求允许访问日历,直到工作正常,但是,在获取事件时显示以下错误。

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。

有人能告诉我哪里做错了吗?

我不明白你为什么会犯这个错误。我想你不是在用最新的豆荚。请参阅下面的代码,这些代码是我用来获取google日历事件的。

吊舱: pod“googleapiclientforrest/calendar”,'~>1.2.1'

pod‘google/signin’,'~>3.0.3'

import UIKit
import GoogleAPIClientForREST
import GoogleSignIn
class ClassForCalEvent: UIViewController, GIDSignInDelegate, GIDSignInUIDelegate {

    let eventArray = NSMutableArray()
    private let scopes = [kGTLRAuthScopeCalendar]

    private let service = GTLRCalendarService()
    override func viewDidLoad() {
        super.viewDidLoad()

          // Configure Google Sign-in.
            GIDSignIn.sharedInstance().delegate = self
            GIDSignIn.sharedInstance().uiDelegate = self
            GIDSignIn.sharedInstance().scopes = scopes
            GIDSignIn.sharedInstance().signIn()

    }

func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
              withError error: Error!) {
        if let error = error {
            showAlert(title: "Authentication Error", message: error.localizedDescription)
            self.service.authorizer = nil
        } else {
                        self.service.authorizer = user.authentication.fetcherAuthorizer()
            fetchEvents()
        }
    }

    // Construct a query and get a list of upcoming events from the user calendar
    func fetchEvents() {
        let query = GTLRCalendarQuery_EventsList.query(withCalendarId: "primary")
        query.maxResults = 10
        query.timeMin = GTLRDateTime(date: Date())
        query.singleEvents = true
        query.orderBy = kGTLRCalendarOrderByStartTime
        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: GTLRServiceTicket,
        finishedWithObject response : GTLRCalendar_Events,
        error : NSError?) {

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

        var outputText = ""
        if let events = response.items, !events.isEmpty {
            for event in events {
                let start = event.start!.dateTime ?? event.start!.date!
                let startString = DateFormatter.localizedString(
                    from: start.date,
                    dateStyle: .short,
                    timeStyle: .short)

                let dataDic = ["start_Time":startString , "tag":"red", "Event_Name":event.summary!] 
                eventArray.add(dataDic)

                outputText += "\(startString) - \(event.summary!)\n"
                print("Output ", startString , event )
            }
            UserDefaults.standard.set(NSKeyedArchiver.archivedData(withRootObject: eventArray), forKey: "EventArray")

            UserDefaults.standard.synchronize()
        } else
        {
            outputText = "No upcoming events found."
        }
        print("Output Text",outputText)
        showAlert(title: "Event Sync Succesfully!", message:"")
    }
