Variables

var APIRoutes = []Route{
	{Path: "/", Method: http.MethodGet, Name: GetAppsRequest, Resource: AppsResource},
	{Path: "/:guid/tasks", Method: http.MethodGet, Name: GetAppTasksRequest, Resource: AppsResource},
	{Path: "/:guid/tasks", Method: http.MethodPost, Name: NewAppTaskRequest, Resource: AppsResource},
}

APIRoutes is a list of routes used by the router to construct request URLs.

Types

type Params

type Params map[string]string

Params map path keys to values. For example, if your route has the path pattern:

/person/:person_id/pets/:pet_type

Then a correct Params map would lool like:

router.Params{
  "person_id": "123",
  "pet_type": "cats",
}

type Route

type Route struct {
	// Name is a key specifying which HTTP route the router should associate with
	// the endpoint at runtime.
	Name string
	// Method is any valid HTTP method
	Method string
	// Path contains a path pattern
	Path string
	// Resource is a key specifying which resource root the router should
	// associate with the endpoint at runtime.
	Resource string
}

Route defines the property of a Cloud Controller V3 endpoint.

Method can be one of the following:

GET HEAD POST PUT PATCH DELETE CONNECT OPTIONS TRACE

Path conforms to Pat-style pattern matching. The following docs are taken from http://godoc.org/github.com/bmizerany/pat#PatternServeMux

Path Patterns may contain literals or captures. Capture names start with a colon and consist of letters A-Z, a-z, _, and 0-9. The rest of the pattern matches literally. The portion of the URL matching each name ends with an occurrence of the character in the pattern immediately following the name, or a /, whichever comes first. It is possible for a name to match the empty string.

Example pattern with one capture:

/hello/:name

Will match:

/hello/blake
/hello/keith

Will not match:

/hello/blake/
/hello/blake/foo
/foo
/foo/bar

Example 2:

/hello/:name/

Will match:

/hello/blake/
/hello/keith/foo
/hello/blake
/hello/keith

Will not match:

/foo
/foo/bar

func (Route) CreatePath

func (r Route) CreatePath(params Params) (string, error)

CreatePath combines the route's path pattern with a Params map to produce a valid path.

type Router

type Router struct {
	// contains filtered or unexported fields
}

Router combines route and resource information in order to generate HTTP requests.

func NewRouter

func NewRouter(routes []Route, resources map[string]string) *Router

NewRouter returns a pointer to a new Router.

func (Router) CreateRequest

func (router Router) CreateRequest(name string, params Params, body io.Reader) (*http.Request, error)

CreateRequest returns a request key'd off of the name given. The params are merged into the URL and body is set as the request body.
