cors

Documentation

Overview

Package cors implements the origin header for CORS.

How It Works

The filter accepts an optional variadic list of acceptable origin parameters. If the input argument list is empty, the header will always be set to '*' which means any origin is acceptable. Otherwise the header is only set if the request contains an Origin header and its value matches one of the elements in the input list. The header is only set on the response.

Usage

corsOrigin()
corsOrigin("https://www.example.org")
corsOrigin("https://www.example.org", "http://localhost:9001")
