Package middleware contains utilities for Goji Middleware authors.

    Unless you are writing middleware for your application, you should avoid importing this package. Instead, use the abstractions provided by your middleware package.

    func Handler

    func Handler(ctx context.Context) goji.Handler

      Handler returns the handler corresponding to the most recently matched Pattern, or nil if no pattern was matched.

      Internally, Goji converts net/http.Handlers into goji.Handlers using a wrapper object. Users who wish to retrieve the original http.Handler they passed to Goji may call UnwrapHandler.

      The handler returned by this function is the one that will be dispatched to at the end of the middleware stack. If the returned Handler is nil, http.NotFound will be used instead.

      func Pattern

      func Pattern(ctx context.Context) goji.Pattern

        Pattern returns the most recently matched Pattern, or nil if no pattern was matched.

        func SetHandler

        func SetHandler(ctx context.Context, h goji.Handler) context.Context

          SetHandler returns a new context in which the given Handler was most recently matched and which consequently will be dispatched to.

          func SetPattern

          func SetPattern(ctx context.Context, p goji.Pattern) context.Context

            SetPattern returns a new context in which the given Pattern is used as the most recently matched pattern.

            func UnwrapHandler

            func UnwrapHandler(h goji.Handler) http.Handler

              UnwrapHandler extracts the original http.Handler from a Goji-wrapped Handler object, or returns nil if the given Handler has not been wrapped in this way.

              This function is necessary because Goji uses goji.Handler as its native data type internally, and uses a wrapper struct to convert all http.Handlers it is passed into goji.Handlers.
