Bearer auth middleware

The bearer auth middleware is a generic bearer token authentication solution for webtasks. A request to a webtask configured with this middleware will be rejected with a 401 response if it lacks the correct bearer token.

Usage

To use the bearer auth middleware requires encoding a shared secret in the wt-auth-secret secret that must be specified in Authentication: Bearer <SHARED_SECRET> headers.

1. Set the wt-node-dependencies metadata property to the stringified JSON of an object having @webtask/middleware-compiler and @webtask/bearer-auth-middleware properties whose values are the latest version of the @webtask/middleware-compiler module and this module, respectively.

   {"@webtask/middleware-compiler":"1.1.0","@webtask/bearer-auth-middleware":"1.1.0"}

2. Set the wt-compiler metadata property on your webtask to @webtask/middleware-compiler.

3. Set (or add to) the wt-middleware metadata property of your webtask to contain a comma-separated list containing @webtask/bearer-auth-middleware.

4. Set the wt-auth-secret secret to a shared secret.

5. Issue requests to your webtask, making sure that you add an Authorization header having the value: Bearer <SHARED_SECRET>.
