示例14: HandleWith

//
//	HandleWith() constructs a handler and inserts it into
//	the mux router.
//
//	It does the following to each request:
//
//	Request Body JSON:
//  - If blank, fills body with {}
//  - Validates based on the schema provided
//		(default: dozy.PresetJsonSchemaBlank)
//
//	Query Strings:
//  - Converts all query strings, except authtoken, to a
//		map[string][]string
//
//	Rate Limiting:
//  - Handles rate limitng on requests with the authtoken in a
//	  URL query string called "authtoken"
//		- Because it only rate handles requests with "authtoken,"
//			it's especially important to use the .Query() function
//			provided by gorilla/mux as much as possible
//
//	Other:
//  - Writes the data specified by the user's handler function,
//		ensuring that only allowed HTTP response codes are used
//		and that no response is sent on error
//  - Sets the "Content-Type" header to "application/json"
//	- Manages the LOCATION header on a dozy.StatusPostOk return
//    value
//	- Ensures that Content-Type from client is correct
//
//	This method **must** be used with a dozy.ServeMux()-handled
//  mux router. dozy.ServeMux() attaches some neccesary data
//  values to the request, which are needed for the proper method
//  of the HandleWith() and the HandleSpecialCost() functions. However,
//  you can use a non dozy.HandleWith() method with the ServeMux()
//  method, only loosing the functionality added with the HandleWith()
//  method itself.
//
func (h handlerBuilder) HandleWith(method, path string, userHandler UserHandler) {
	method = strings.ToUpper(method)
	if (method == "GET" || method == "DELETE") && h.bodySchema != PresetJsonSchemaBlank {
		panic("Method type " + method + " should not have a body set!")
	}

	builtHandler := func(rw http.ResponseWriter, req *http.Request) {
		var cost uint

		if h.customCost {
			rawSettings, rawSettingsOk := context.GetOk(req, dozySettingsKey("settings"))
			settings, settingsOk := rawSettings.(*Settings)
			if !rawSettingsOk {
				panic("rawSettings is *not* okay!")
			}
			if !settingsOk {
				panic("settings is *not* okay!")
			}

			cost = settings.DefaultCost
		} else {
			cost = h.cost
		}

		handle(h.bodySchema, userHandler, cost, rw, req)
	}

	route := h.muxRouter.HandleFunc(path, builtHandler).Methods(method)
	if len(h.queries) != 0 {
		route.Queries(h.queries...)

示例15: Value

// Value returns Gorilla's context package's value for this Context's request
// and key. It delegates to the parent Context if there is no such value.

		return val
	}

	return ctx.Context.Value(key)
