Package software.amazon.smithy.aws.apigateway.openapi

Class CorsHttpIntegration

java.lang.Object

software.amazon.smithy.aws.apigateway.openapi.CorsHttpIntegration

All Implemented Interfaces:

ApiGatewayMapper, OpenApiMapper

public final class CorsHttpIntegration
extends Object
implements ApiGatewayMapper

Adds support for the API Gateway x-amazon-apigateway-cors extension for API Gateway HTTP APIs using values from the Smithy cors trait.

• allowOrigins is populated based on the origin property of the cors trait.
• maxAge is populated based on the maxAge property of the cors trait.
• allowMethods is populated by scanning the generated OpenAPI definition for every defined method.
• exposedHeaders is set to "*" to expose all headers IFF the service does not use HTTP credentials, and no value is provided to the additionalExposedHeaders property of the Smithy cors trait. Otherwise, this value is populated by finding all of the response headers used by the protocol, modeled in the service, and used by auth schemes.
• allowedHeaders is set to "*" to allow all headers IFF the service does not use HTTP credentials, and no value is provided to the additionalAllowedHeaders property of the Smithy cors trait. Otherwise, this value is populated by finding all of the request headers used by the protocol, modeled in the service, and used by auth schemes.
• allowCredentials is set to true if any of the auth schemes used in the API use HTTP credentials according to Context.usesHttpCredentials().
