cors-examples

What is this?

This repository is a collection of examples that illustrate how to use github.com/jub0bs/cors, a principled CORS middleware library, in conjunction with net/http and popular third-party routers for Go.

What is the example?

The example invariably consists in creating a CORS middleware that

• allows anonymous access from Web origin https://example.com,
• with requests whose method is either GET or POST, and
• (optionally) with request header Authorization,

and applying the middleware in question to all the resources accessible under an /api/ path.

In addition, a /hello path is left unconfigured for CORS.
