swift - AWS Pool.Signup 不会在 Swift 3 的 block 内执行代码

Question

好的，我开始使用 AWS Cognito，但陷入了用户注册...

这就是我的问题发生的地方:

    func register(userNameChosen:String, attributes:[AWSCognitoIdentityUserAttributeType]) {
    let task = self.pool.signUp(userNameChosen, password: senhaTextField.text!, userAttributes: attributes, validationData: nil)

    task.continue(with: AWSExecutor.default(), with: { (task) -> Any? in

            if task.error != nil { //error occur
                let alert:UIAlertController = UIAlertController(title: "Error", message: task.error?.localizedDescription, preferredStyle: UIAlertControllerStyle.alert)
                alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.default, handler: nil))
                self.present(alert, animated: true, completion: nil)



            } else { //no error
                print("no error")
                let response:AWSCognitoIdentityUserPoolSignUpResponse = task.result! as AWSCognitoIdentityUserPoolSignUpResponse
                self.user = response.user

                if response.userConfirmed as! Int != AWSCognitoIdentityUserStatus.confirmed.rawValue { //user not confirmed via email
                    //setup para mandar atraves de Segue
                    self.sentTo = response.codeDeliveryDetails?.destination
                    self.performSegue(withIdentifier: "confirmSignUp", sender: self)

                } else { 
                    print("User already confirmed?")
                    self.navigationController?.popToRootViewController(animated: true) //back to login      
                }

            }

        return nil
    }).waitUntilFinished()
}

问题是下面的代码

task.continue(with: AWSExecutor.default(), with: { (task) -> Any? in

不会执行...该应用程序已经与 AWS 进行了良好的通信。当我使用“登录可选”运行它时，即使未经身份验证，它也会获取 AWS token 。但是，当我在 Mobile Hub - Cognito 将“登录”设置为“必需”时，我收到以下消息(我认为这不是问题的一部分，因为在注册之前，您显然未经身份验证):

[26851:2009541] AWSiOSSDK v2.4.9 [Error] AWSIdentityProvider.m line:304 | __52-[AWSCognitoCredentialsProviderHelper getIdentityId]_block_invoke255 | GetId failed. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityErrorDomain Code=8 "(null)" UserInfo={__type=NotAuthorizedException, message=Unauthenticated access is not supported for this identity pool.}]

或者

[26851:2009539] [] -[NWConcrete_tcp_connection dealloc] 1

Answer 1

我明白了。问题是，如果没有从 AWSTask 获得“响应”，它就不会进入该 block ，也不会抛出错误。

我的凭据配置有些错误，因此它无法附加到我的用户池。

这是我使用的代码，如果有人使用 Swift 3.0。

let serviceConfiguration:AWSServiceConfiguration = AWSServiceConfiguration.init(region: .usEast1, credentialsProvider: nil)

    let configuration:AWSCognitoIdentityUserPoolConfiguration = AWSCognitoIdentityUserPoolConfiguration(clientId: "PUT_YOUR_CLIENT_ID_HERE", clientSecret: PUT_YOUR_CLIENT_SECRET_HERE, poolId: "PUT_YOUR_POOL_ID_HERE")
    AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: configuration, forKey: "UserPool")

    AWSServiceManager.default().defaultServiceConfiguration = serviceConfiguration

如果您的客户端 key 为空，请使用 nil，不要使用“”。我强烈建议您使用客户端 key 。
