我正在迅速开发一个应用程序,并且使用AWS移动服务进行身份验证,并使用AWS Lambda进行一些后端处理。我一切正常,有一天(离开应用程序一个月左右),它开始抛出此错误:
GetId failed. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set" UserInfo {NSLocalizedDescription=Authentication delegate not set}]
Unable to refresh. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set"
它正在杀死我,因为它已经起作用了。可能会发生什么变化?
在appDelegate中,我有:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
// Uncomment to turn on logging, look for "Welcome to AWS!" to confirm success
AWSDDLog.add(AWSDDTTYLogger.sharedInstance)
AWSDDLog.sharedInstance.logLevel = .error
// Instantiate AWSMobileClient to get AWS user credentials
return AWSMobileClient.sharedInstance().interceptApplication(application, didFinishLaunchingWithOptions:launchOptions)
}
它实际上在我进行任何调用之前就引发了错误,所以我认为以上几行可能触发了问题?
要登录,请在主viewController中执行以下操作:
override func viewDidLoad() {
super.viewDidLoad()
if !AWSSignInManager.sharedInstance().isLoggedIn {
presentAuthUIViewController()
}
else{
getCredentials()
}
...
}
func presentAuthUIViewController() {
let config = AWSAuthUIConfiguration()
config.enableUserPoolsUI = true
config.backgroundColor = UIColor.white
config.logoImage = #imageLiteral(resourceName: "logoQ")
config.isBackgroundColorFullScreen = true
config.canCancel = true
AWSAuthUIViewController.presentViewController(
with: self.navigationController!,
configuration: config, completionHandler: { (provider:
AWSSignInProvider, error: Error?) in
if error == nil {
self.getCredentials()
} else {
// end user faced error while loggin in, take any required action here.
}
})
}
func getCredentials() {
let serviceConfiguration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: nil)
let userPoolConfiguration = AWSCognitoIdentityUserPoolConfiguration(clientId: "id",
clientSecret: "secret",
poolId: "id")
AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: userPoolConfiguration, forKey: "key")
let pool = AWSCognitoIdentityUserPool(forKey: "key")
if let username = pool.currentUser()?.username {
userName = username
}
登录后,我会检索用户名。
有什么提示吗?我遵循了其他帖子中的一些说明,但是它们没有用,而且最让我感到不安的是它还在用!
预先感谢

因此,不是100%确定发生了什么,但是据我了解,用户池中用户的凭据存在问题。我重设了密码,然后一切又恢复正常了!
我有人需要更多细节,只是问一下,如果有人更好地理解了,请告诉我。

我认为这意味着您的刷新令牌已过期。
