AWS Settings

Client applications need configuration information to initialize their communication with your AWS Stack. This is provided by an LazyStack generated AwsSettings.json file.

Security Levels

  1. None

    The ApiGateway allows any valid HttpRequest.

  2. JWT

    The ApiGateway requires the HttpRequest Authorization Header contain a valid Jason Web Token issued by Cognito.

  3. AwsSignatureVersion4

    The ApiGateway requires the HttpRequest Authorization Header contain a computed signature of the HttpRequest. This means every HttpRequest has a unique signature computed on the client and then computed again by the ApiGateway. The results must match for the HttpRequest to be processed.

You may generate the AwsSettings.json file for the Development environment using the LazyStack Visual Studio IDE extension command: "Tools -> LazyStack - Generate Dev_AwsSettings.json". This file is generated into the Solution's root folder and is visible in the Solution Explorer "Solution Items" folder.

The LazyStack AWS Settings Generator generates the AwsSettings file using your default AWS profile and making calls against AWS CloudFormation to retrieve published stack information. It also uses the Solution's serverless.template file to get the SecurityLevel of each ApiGateway.

To generate an AwsSettings file for another stack, say your production stack, switch to the appropriate AWS profile and use the NET CLI command.
