ship Build Status GoDoc License

ship is a flexible, powerful, high performance and minimalist Go Web HTTP router framework supporting Go 1.11+. It is inspired by echo and httprouter. Thanks for those contributors.

Features

  • Support the url parameter.
  • Support the session manager.
  • Support the customized router manager.
  • Support the pre-route and route middlewares.
  • Support the route group builder to build the route.
  • Support the mulit-virtual hosts and the default host.
  • Support the exact, prefix, suffix and regexp hostname.
  • Support the binding of the request data, such as body and query.
  • Support the renderer, such as the HTML template.
  • ......
Components
  • Ship is the pure router framework based on the method and the path, including Middleware, Context, Router, etc.
  • HostManager and HostHandler are the vhost manager and the standard http handler with the vhost manager.
  • Runner is the runner to start the http server with the standard http handler.

Install

go get -u github.com/xgfone/ship/v5

Quick Start

// example.go
package main

import (
	"github.com/xgfone/ship/v5"
	"github.com/xgfone/ship/v5/middleware"
)

func main() {
	router := ship.New()
	router.Use(middleware.Logger(), middleware.Recover()) // Use the middlewares.

	router.Route("/ping").GET(func(c *ship.Context) error {
		return c.JSON(200, map[string]interface{}{"message": "pong"})
	})

	group := router.Group("/group")
	group.Route("/ping").GET(func(c *ship.Context) error {
		return c.Text(200, "group")
	})

	subgroup := group.Group("/subgroup")
	subgroup.Route("/ping").GET(func(c *ship.Context) error {
		return c.Text(200, "subgroup")
	})

	// Start the HTTP server.
	ship.StartServer(":8080", router)
	// or
	// http.ListenAndServe(":8080", router)
}

$ go run example.go

$ curl http://127.0.0.1:8080/ping
{"message":"pong"}

$ curl http://127.0.0.1:8080/group/ping
group

$ curl http://127.0.0.1:8080/group/subgroup/ping
subgroup
Route Path

The route path supports the parameters like :paramName, * or *restParamName.

  • /path/to/route only matches the path /path/to/route.
  • /path/:param1/to matches the path /path/abc/to, /path/xyz/to, etc. And :param1 is equal to abc or xyz.
  • /path/:param1/to/:param2 matches the path /path/p11/to/p21, /path/p12/to/p22, etc. And :parma1 is equal to p11 or p12, and :param2 is equal to p12 or p22.
  • /path/to/* or /path/to/*all matches the path /path/to/abc, /path/to/abc/efg, /path/to/xyz, /path/to/xyz/123, etc. And * or *all is equal to abc, abc/efg, xyz, or xzy/123. Notice: * or *restParamName must be the last one of the route path.
  • /path/:param/to/* matches the path /path/abc/to/efg, /path/abc/to/efg/123, etc. And :param is equal to abc, and * is equal to efg or efg/123

For the parameter, it can be accessed by Context.Param(paramName).

  • For *, the parameter name is *, like Context.Param("*").
  • For *restParamName, the parameter name is restParamName, like Context.Param(restParamName).

API Example

Route Builder
Using CONNECT, HEAD, GET, POST, PUT, PATCH, DELETE and OPTIONS
func main() {
	router := ship.New()
	router.Route("/path/get").GET(getHandler)
	router.Route("/path/put").PUT(putHandler)
	router.Route("/path/head").HEAD(headHandler)
	router.Route("/path/post").POST(postHandler)
	router.Route("/path/patch").PATCH(patchHandler)
	router.Route("/path/delete").DELETE(deleteHandler)
	router.Route("/path/option").OPTIONS(optionHandler)
	router.Route("/path/connect").CONNECT(connectHandler)
	ship.StartServer(":8080", router)
}

Notice: you can register the same handler with more than one method by Route(path string).Method(handler Handler, method ...string).

Cascade the registered routes
func main() {
	router := ship.New()
	router.Route("/path/to").GET(getHandler).POST(postHandler).DELETE(deleteHandler)
	ship.StartServer(":8080", router)
}
Use the mapping of the route methods
func main() {
	router := ship.New()
	router.Route("/path/to").Map(map[string]ship.Handler{
		"GET": getHandler,
		"POST": postHandler,
		"DELETE": deleteHandler,
	})
	ship.StartServer(":8080", router)
}
Name the route

When registering the route, it can be named with a name.

func main() {
	router := ship.New()
	router.Route("/path/:id").Name("get_url").GET(func(c *ship.Context) error {
		fmt.Println(c.URL("get_url", c.Param("id")))
		return nil
	})
	ship.StartServer(":8080", router)
}
Use the route group
package main

import (
	"github.com/xgfone/ship/v5"
	"github.com/xgfone/ship/v5/middleware"
)

// MyAuthMiddleware returns a middleare to authenticate the request.
func MyAuthMiddleware() ship.Middleware {
	return func(next ship.Handler) ship.Handler {
		return func(c *ship.Context) error {
			// TODO: authenticate the request.
			return next(c)
		}
	}
}

func main() {
	router := ship.New()
	router.Use(middleware.Logger(), middleware.Recover())

	// v1 Group, which will inherit the middlewares of the parent router.
	v1 := router.Group("/v1")
	v1.Route("/get").GET(func(c *ship.Context) error { return nil }) // Route: GET /v1/get

	// v2 Group, which won't inherit the middlewares of the parent router.
	v2 := router.Group("/v2").ResetMiddlewares(MyAuthMiddleware())
	v2.Route("/post").POST(func(c *ship.Context) error { return nil }) // Route: POST /v2/post

	// For sub-group of v2 Group.
	v2g := v2.Group("/child")
	v2g.Route("/path").GET(func(c *ship.Context) error { return nil }) // Route: GET /v2/child/path

	ship.StartServer(":8080", router)
}
Filter the unacceptable routes
package main

import (
	"strings"

	"github.com/xgfone/ship/v5"
)

func filter(ri ship.Route) bool {
	if ri.Name == "" || !strings.HasPrefix(ri.Path, "/prefix/") {
		return true
	}
	return false
}

func main() {
	handler := func(c *ship.Context) error { return nil }

	router := ship.New()
	router.RouteFilter = filter // Don't register the router without name.

	router.Group("/prefix").Route("/name").Name("test").GET(handler) // Register the route
	router.Group("/prefix").Route("/noname").GET(handler)            // Don't register the route
	router.Route("/no_group").GET(handler)                           // Don't register the route

	ship.StartServer(":8080", router)
}
Modify the route before registering it
package main

import "github.com/xgfone/ship/v5"

func modifier(ri ship.Route) ship.Route {
	ri.Path = "/prefix" + ri.Path
	return ri
}

func main() {
	handler := func(c *ship.Context) error { return nil }

	router := ship.New()
	router.RouteModifier = modifier
	router.Route("/path").Name("test").GET(handler) // Register the path as "/prefix/path".

	ship.StartServer(":8080", router)
}
Use Middleware
package main

import (
	"fmt"
	"strings"

	"github.com/xgfone/ship/v5"
	"github.com/xgfone/ship/v5/middleware"
)

// RemovePathPrefix returns a middleware to remove the prefix from the request path.
func RemovePathPrefix(prefix string) ship.Middleware {
	if len(prefix) < 2 || prefix[len(prefix)-1] == '/' {
		panic(fmt.Errorf("invalid prefix: '%s'", prefix))
	}

	return func(next ship.Handler) ship.Handler {
		return func(c *ship.Context) error {
			req := c.Request()
			req.URL.Path = strings.TrimPrefix(req.URL.Path, prefix)
			return next(c)
		}
	}
}

func main() {
	router := ship.New()

	// Execute the middlewares before finding the route.
	router.Pre(RemovePathPrefix("/static"))

	// Execute the middlewares after finding the route.
	router.Use(middleware.Logger(), middleware.Recover())

	handler := func(c *ship.Context) error { return nil }
	router.Route("/path1").GET(handler)
	router.Route("/path2").GET(handler)
	router.Route("/path3").GET(handler)

	ship.StartServer(":8080", router)
}
Use the virtual host
package main

import (
	"github.com/xgfone/ship/v5"
)

func main() {
	vhosts := ship.NewHostManagerHandler(nil)

	_default := ship.New()
	_default.Route("/").GET(func(c *ship.Context) error { return c.Text(200, "default") })
	vhosts.SetDefaultHost("", _default)

	// Exact Match Host
	vhost1 := ship.New()
	vhost1.Route("/").GET(func(c *ship.Context) error { return c.Text(200, "vhost1") })
	vhosts.AddHost("www.host1.example.com", vhost1)

	// Suffix Match Host
	vhost2 := ship.New()
	vhost2.Route("/").GET(func(c *ship.Context) error { return c.Text(200, "vhost2") })
	vhosts.AddHost("*.host2.example.com", vhost2)

	// Prefix Match Host
	vhost3 := ship.New()
	vhost3.Route("/").GET(func(c *ship.Context) error { return c.Text(200, "vhost3") })
	vhosts.AddHost("www.host3.*", vhost3)

	// Regexp Match Host by using Go regexp package
	vhost4 := ship.New()
	vhost4.Route("/").GET(func(c *ship.Context) error { return c.Text(200, "vhost4") })
	vhosts.AddHost(`www\.[a-zA-z0-9]+\.example\.com`, vhost4)

	ship.StartServer(":8080", vhosts)
}

$ curl http://127.0.0.1:8080/
default

$ curl http://127.0.0.1:8080/ -H 'Host: www.host1.example.com' # Exact
vhost1

$ curl http://127.0.0.1:8080/ -H 'Host: www.host2.example.com' # Suffix
vhost2

$ curl http://127.0.0.1:8080/ -H 'Host: www.host3.example.com' # Prefix
vhost3

$ curl http://127.0.0.1:8080/ -H 'Host: www.host4.example.com' # Regexp
vhost4
Handle the complex response
package main

import "github.com/xgfone/ship/v5"

func responder(c *ship.Context, args ...interface{}) error {
	switch len(args) {
	case 0:
		return c.NoContent(200)
	case 1:
		switch v := args[0].(type) {
		case int:
			return c.NoContent(v)
		case string:
			return c.Text(200, v)
		}
	case 2:
		switch v0 := args[0].(type) {
		case int:
			return c.Text(v0, "%v", args[1])
		}
	}
	return c.NoContent(500)
}

func main() {
	router := ship.New()
	router.Responder = responder
	router.Route("/path1").GET(func(c *ship.Context) error { return c.Respond() })
	router.Route("/path2").GET(func(c *ship.Context) error { return c.Respond(200) })
	router.Route("/path3").GET(func(c *ship.Context) error { return c.Respond("Hello, World") })
	router.Route("/path4").GET(func(c *ship.Context) error { return c.Respond(200, "Hello, World") })
	ship.StartServer(":8080", router)
}
Bind JSON, XML or Form data from the request payload
package main

import "github.com/xgfone/ship/v5"

// Login is the login information.
type Login struct {
	Username string `json:"username" xml:"username"`
	Password string `json:"password" xml:"password"`
}

func main() {
	router := ship.Default()
	router.Route("/login").POST(func(c *ship.Context) (err error) {
		var login Login
		if err = c.Bind(&login); err != nil {
			return ship.ErrBadRequest.New(err)
		}
		return c.Text(200, "username=%s, password=%s", login.Username, login.Password)
	})

	ship.StartServer(":8080", router)
}

$ curl http://127.0.0.1:8080/login \
    -H 'Content-Type: application/json' \
    -d '{"username":"xgfone","password":"123456"}'
username=xgfone, password=123456

$ curl http://127.0.0.1:8080/login \
    -H 'Content-Type: application/xml' \
    -d '<login><username>xgfone</username><password>123456</password></login>'
username=xgfone, password=123456
Render HTML template

In the directory /path/to/templates, there is a template file named index.tmpl as follow:

<!DOCTYPE html>
<html>
    <head></head>
    <body>
        This is the body content: </pre>{{ . }}</pre>
    </body>
</html>

package main

import (
	"github.com/xgfone/ship/v5"
	"github.com/xgfone/ship/v5/render/template"
)

func main() {
	// It will recursively load all the files in the directory as the templates.
	loader := template.NewDirLoader("/path/to/templates")
	tmplRender := template.NewHTMLTemplateRender(loader)

	router := ship.Default()
	router.Renderer.(*ship.MuxRenderer).Add(".tmpl", tmplRender)
	router.Route("/html").GET(func(c *ship.Context) error {
		return c.RenderOk("index.tmpl", "Hello World")
	})

	// Start the HTTP server.
	ship.StartServer(":8080", router)
}

When accessing http://127.0.0.1:8080/html, it returns

<!DOCTYPE html>
<html>
    <head></head>
    <body>
        This is the body content: </pre>Hello World</pre>
    </body>
</html>

Route Management

ship supply a default implementation based on Radix tree to manage the route with Zero Garbage (See Benchmark), which refers to echo, that's, NewRouter().

You can appoint your own implementation by implementing the interface Router.

type Router interface {
	// Range traverses all the registered routes.
	Range(func(name, path, method string, handler interface{}))

	// Path generates a url path by the path name and parameters.
	//
	// Return "" if there is not the route path named name.
	Path(name string, params ...interface{}) string

	// Add adds the route and returns the number of the parameters
	// if there are the parameters in the route path.
	//
	// name is the name of the path, which is optional and must be unique
	// if not empty.
	//
	// If method is empty, handler is the handler of all the methods supported
	// by the implementation. Or, it is only that of the given method.
	//
	// For the parameter in the path, the format is determined by the implementation.
	Add(name, path, method string, handler interface{}) (paramNum int, err error)

	// Del deletes the given route.
	//
	// If method is empty, deletes all the routes associated with the path.
	// Or, only delete the given method for the path.
	Del(path, method string) (err error)

	// Match matches the route by path and method, puts the path parameters
	// into pnames and pvalues, then returns the handler and the number
	// of the path paramethers.
	//
	// If pnames or pvalues is empty, it will ignore the path paramethers
	// when finding the route handler.
	//
	// Return (nil, 0) if not found the route handler.
	Match(path, method string, pnames, pvalues []string) (handler interface{}, pn int)
}

func main() {
	NewMyRouter := func() (router ship.Router) {
		// TODO: new a Router.
		return
	}

	router := ship.New()
	router.Router = NewMyRouter()
	// ...
}

For the type of the field, it only supports some base types as follow: 

string
float32
float64
int
int8
int16
int32
int64
uint
uint8
uint16
uint32
uint64
struct

time.Time      // Format: A. Integer(UTC); B. String(RFC3339)
time.Duration  // Format: A. Integer(ms);  B. String(time.ParseDuration)
pointer to the types above

Notice: If the tag value starts with ".", it represents a field name and the default value of current field is set to the value of that field. But their types must be consistent, or panic.

func SplitHostPort 

func SplitHostPort(hostport string) (host, port string)

SplitHostPort separates host and port. If the port is not valid, it returns the entire input as host, and it doesn't check the validity of the host. Unlike net.SplitHostPort, but per RFC 3986, it requires ports to be numeric.

Example 
var host, port string

host, port = SplitHostPort("www.example.com")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

host, port = SplitHostPort("www.example.com:80")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

host, port = SplitHostPort(":80")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

host, port = SplitHostPort("1.2.3.4:80")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

host, port = SplitHostPort("[fe80::1122:3344:5566:7788]")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

host, port = SplitHostPort("[fe80::1122:3344:5566:7788]:80")
fmt.Printf("Host: %s, Port: %s#\n", host, port)

Output:

Host: www.example.com, Port: #
Host: www.example.com, Port: 80#
Host: , Port: 80#
Host: 1.2.3.4, Port: 80#
Host: fe80::1122:3344:5566:7788, Port: #
