// Package chi is a small, idiomatic and composable router for building HTTP services.
|
|
//
|
|
// chi requires Go 1.10 or newer.
|
|
//
|
|
// Example:
|
|
// package main
|
|
//
|
|
// import (
|
|
// "net/http"
|
|
//
|
|
// "github.com/go-chi/chi"
|
|
// "github.com/go-chi/chi/middleware"
|
|
// )
|
|
//
|
|
// func main() {
|
|
// r := chi.NewRouter()
|
|
// r.Use(middleware.Logger)
|
|
// r.Use(middleware.Recoverer)
|
|
//
|
|
// r.Get("/", func(w http.ResponseWriter, r *http.Request) {
|
|
// w.Write([]byte("root."))
|
|
// })
|
|
//
|
|
// http.ListenAndServe(":3333", r)
|
|
// }
|
|
//
|
|
// See github.com/go-chi/chi/_examples/ for more in-depth examples.
|
|
//
|
|
// URL patterns allow for easy matching of path components in HTTP
|
|
// requests. The matching components can then be accessed using
|
|
// chi.URLParam(). All patterns must begin with a slash.
|
|
//
|
|
// A simple named placeholder {name} matches any sequence of characters
|
|
// up to the next / or the end of the URL. Trailing slashes on paths must
|
|
// be handled explicitly.
|
|
//
|
|
// A placeholder with a name followed by a colon allows a regular
|
|
// expression match, for example {number:\\d+}. The regular expression
|
|
// syntax is Go's normal regexp RE2 syntax, except that regular expressions
|
|
// including { or } are not supported, and / will never be
|
|
// matched. An anonymous regexp pattern is allowed, using an empty string
|
|
// before the colon in the placeholder, such as {:\\d+}
|
|
//
|
|
// The special placeholder of asterisk matches the rest of the requested
|
|
// URL. Any trailing characters in the pattern are ignored. This is the only
|
|
// placeholder which will match / characters.
|
|
//
|
|
// Examples:
|
|
// "/user/{name}" matches "/user/jsmith" but not "/user/jsmith/info" or "/user/jsmith/"
|
|
// "/user/{name}/info" matches "/user/jsmith/info"
|
|
// "/page/*" matches "/page/intro/latest"
|
|
// "/page/*/index" also matches "/page/intro/latest"
|
|
// "/date/{yyyy:\\d\\d\\d\\d}/{mm:\\d\\d}/{dd:\\d\\d}" matches "/date/2017/04/01"
|
|
