Functions

func RegisterControlRoutes added in v0.11.0

func RegisterControlRoutes(router *mux.Router, cr ControlRouter)

RegisterControlRoutes registers the various control routes with a http mux.

func RegisterPipeRoutes added in v0.11.0

func RegisterPipeRoutes(router *mux.Router, pr PipeRouter)

RegisterPipeRoutes registers the pipe routes

func RegisterReportPostHandler added in v0.11.0

func RegisterReportPostHandler(a Adder, router *mux.Router)

RegisterReportPostHandler registers the handler for report submission

func RegisterTopologyRoutes added in v0.11.0

func RegisterTopologyRoutes(router *mux.Router, r Reporter)

RegisterTopologyRoutes registers the various topology routes with a http mux.

func URLMatcher added in v0.5.0

func URLMatcher(pattern string) mux.MatcherFunc

URLMatcher uses request.RequestURI (the raw, unparsed request) to attempt to match pattern. It does this as go's URL.Parse method is broken, and mistakenly unescapes the Path before parsing it. This breaks %2F (encoded forward slashes) in the paths.

Types

type APINode struct {
	Node detailed.Node `json:"node"`
}

APINode is returned by the /api/topology/{name}/{id} handler.
