Features

• ✅ Supports an array of keys
• ✅ Supports overriding thrown errors
• ✅ 100% Test Coverage

Usage

Requests are expected to have the header api-key.

Simple

public func configure(_ app: Application) throws {
    app.middleware.use(APIKeyMiddleware(keys: ["123"]))
}

See Vapor Docs if wanting to add to individual routes.

Override Errors

The following errors are used by default:

• Missing API key: Abort(.badRequest, reason: "Missing api-key.")
• Unauthorized API Key: Abort(.unauthorized, reason: "Unauthorized api-key.")

To override these errors, assign a delegate to the APIKeyMiddleware. Returning nil uses defaults.

class Delegate: APIKeyMiddlewareDelegate {

    static let shared = Delegate()

    init() {}

    func errorForMissingKey(in middleware: APIKeyMiddleware) -> Error? {
        Abort(.imATeapot, reason: "Missing api-key was found by teapot.")
    }

    func errorForUnauthorizedKey(in middleware: APIKeyMiddleware) -> Error? {
        Abort(.imATeapot, reason: "Unauthorized api-key was found by teapot.")
    }
}

public func configure(_ app: Application) throws {
    let middleware = APIKeyMiddleware(keys: ["123"], delegate: Delegate.shared)
    app.middleware.use(middleware)
}
