Question

我正在使用Xcode（Swift）。我尝试编写将注册，确认用户并登录用户到用户池的代码。然后，在成功登录后，我希望它与Amazon Cognito Identity链接。基本上，我希望在用户池中拥有尽可能多的用户身份ID。

到目前为止，我可以注册，确认用户并登录（使用显式登录）。登录成功后，我尝试将此用户链接到Cognito Identity Pool，以便为该用户生成唯一ID。

目前，如果我以不同的用户身份登录应用程序，则会为其分配与前一个用户相同的身份标识。换句话说，无论我的用户池中有多少用户，在AWS Cogntio联合身份池方面，我只有一个身份标识。理想情况下，它应该为不同的用户创建单独的标识ID。

以下是didFinishLaunchingWithOptions函数中App委托中的代码。

let serviceConfiguration = AWSServiceConfiguration(region: AWSRegionType.USEast1, credentialsProvider: nil)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = serviceConfiguration
let configurationUserPool = AWSCognitoIdentityUserPoolConfiguration.init(clientId: "####", clientSecret: "####", poolId: "####")
AWSCognitoIdentityUserPool.registerCognitoIdentityUserPoolWithConfiguration(serviceConfiguration, userPoolConfiguration: configurationUserPool, forKey: "testPool")
self.userPool = AWSCognitoIdentityUserPool(forKey: "testPool")

以下是Sign View控制器中的代码。

@IBAction func signIn(sender: AnyObject) {

    let user = self.userPool.getUser(userName.text!)

    user.getSession(userName.text!, password: password.text!, validationData: nil, scopes: nil).continueWithExecutor(AWSExecutor.mainThreadExecutor(), withBlock: {
        (task:AWSTask!) -> AnyObject! in

        if task.error != nil {
            print(task.error)
        } else {
            print("Successful Login")

            let cp = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "######", identityProviderManager:self.userPool)
            let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: cp)

            AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration                
            cp.getIdentityId().continueWithBlock { (task: AWSTask!) -> AnyObject! in

                if (task.error != nil) {
                    print("Error: ")

                } else {
                    // the task result will contain the identity id
                    print("Success with id")
                    print(task.result)
                }
                return nil
            }

            dispatch_async(dispatch_get_main_queue()){
               // do stuff here ...
            }
        }
        return nil
    })
}

最后，我能够纠正这个问题。问题是我每次登录新用户时都会重置凭据提供程序。当我把它移到App Delegate时，它开始以它应该的方式工作。

这不应该是signIn函数，而应该是App Delegate。

let cp = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "######", identityProviderManager:self.userPool)
let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: cp)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration

正确的方式。

let serviceConfiguration = AWSServiceConfiguration(region: AWSRegionType.USEast1, credentialsProvider: nil)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = serviceConfiguration
let configurationUserPool = AWSCognitoIdentityUserPoolConfiguration.init(clientId: "####", clientSecret: "####", poolId: "####")
AWSCognitoIdentityUserPool.registerCognitoIdentityUserPoolWithConfiguration(serviceConfiguration, userPoolConfiguration: configurationUserPool, forKey: "testPool")
self.userPool = AWSCognitoIdentityUserPool(forKey: "testPool")
self.cp = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "######", identityProviderManager:self.userPool)
let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: self.cp)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration
