ThinkGo
ThinkGo is a lightweight MVC framework written in Go (Golang).
Installation
The only requirement is the Go Programming Language
go get -u github.com/forgoer/thinkgo
Quick start
package main
import (
"fmt"
"github.com/forgoer/thinkgo"
"github.com/forgoer/thinkgo/think"
)
func main() {
th := thinkgo.New()
th.RegisterRoute(func(route *think.Route) {
route.Get("/", func(req *think.Req) *think.Res {
return think.Text("Hello ThinkGo !")
})
route.Get("/ping", func(req *think.Req) *think.Res {
return think.Json(map[string]string{
"message": "pong",
})
})
// Dependency injection
route.Get("/user/{name}", func(req *think.Req, name string) *think.Res {
return think.Text(fmt.Sprintf("Hello %s !", name))
})
})
// listen and serve on 0.0.0.0:9011
th.Run()
}
Features
Routing
Basic Routing
The most basic routes accept a URI and a Closure, providing a very simple and expressive method of defining routes:
think.RegisterRoute(func(route *router.Route) {
route.Get("/foo", func(req *context.Request) *context.Response {
return thinkgo.Text("Hello ThinkGo !")
})
})
Available Router Methods
The router allows you to register routes that respond to any HTTP verb:
route.Get("/someGet", getting)
route.Post("/somePost", posting)
route.Put("/somePut", putting)
route.Delete("/someDelete", deleting)
route.Patch("/somePatch", patching)
route.Options("/someOptions", options)
Sometimes you may need to register a route that responds to multiple HTTP verbs. You may even register a route that responds to all HTTP verbs using the Any method:
route.Any("/someAny", any)
Parameters in path
Of course, sometimes you will need to capture segments of the URI within your route. For example, you may need to capture a user's ID from the URL. You may do so by defining route parameters:
route.Get("/user/{id}", func(req *context.Request, id string) *context.Response {
return thinkgo.Text(fmt.Sprintf("User %s", id))
})
You may define as many route parameters as required by your route:
route.Get("/posts/{post}/comments/{comment}", func(req *context.Request, postId, commentId string) *context.Response {
//
})
Route Prefixes
The prefix method may be used to prefix each route in the group with a given URI. For example, you may want to prefix all route URIs within the group with admin:
route.Prefix("/admin").Group(func(group *router.Route) {
group.Prefix("user").Group(func(group *router.Route) {
// ...
})
group.Prefix("posts").Group(func(group *router.Route) {
// ...
})
})
Route Groups
Route groups allow you to share route attributes, such as middleware or prefix, across a large number of routes without needing to define those attributes on each individual route.
route.Prefix("/admin").Group(func(group *router.Route) {
group.Prefix("user").Group(func(group *router.Route) {
group.Get("", func(request *context.Request) *context.Response {
return thinkgo.Text("admin user !")
}).Middleware(func(request *context.Request, next router.Closure) interface{} {
if _, err := request.Input("id"); err != nil {
return thinkgo.Text("Invalid parameters")
}
return next(request)
})
group.Get("edit", func(request *context.Request) *context.Response {
return thinkgo.Text("admin user edit !")
})
}).Middleware(func(request *context.Request, next router.Closure) interface{} {
if _, err := request.Input("user"); err != nil {
return thinkgo.Text("Invalid parameters")
}
return next(request)
})
}).Middleware(func(request *context.Request, next router.Closure) interface{} {
if _, err := request.Input("token"); err != nil {
return thinkgo.Text("Invalid parameters")
}
return next(request)
})
Middleware
Middleware provide a convenient mechanism for filtering HTTP requests entering your application. You only need to implement the Middleware interface.
route.Get("/foo", func(request *context.Request) *context.Response {
return thinkgo.Text("Hello ThinkGo !")
}).Middleware(func(request *context.Request, next router.Closure) interface{} {
if _, err := request.Input("name"); err != nil {
return thinkgo.Text("Invalid parameters")
}
return next(request)
})
Before Middleware
Whether a middleware runs before or after a request depends on the middleware itself. For example, the following middleware would perform some task before the request is handled by the application:
func(request *context.Request, next router.Closure) interface{} {
// Perform action
// ...
return next(request)
}
After Middleware
However, this middleware would perform its task after the request is handled by the application:
func(request *context.Request, next router.Closure) interface{} {
response := next(request)
// Perform action
// ...
return response
}
Controller
Basic Controller
Below is an example of a basic controller class.
package controller
import (
"github.com/forgoer/thinkgo"
"github.com/forgoer/thinkgo/context"
)
func Index(req *context.Request) *context.Response {
return thinkgo.Text("Hello ThinkGo !")
}
You can define a route to this controller like so:
route.Get("/", controller.Index)
Resource Controller
This feature will be supported in a future release.
HTTP Request
Accessing The Request
To obtain an instance of the current HTTP request via dependency injection
func Handler(req *context.Request) *context.Response {
name := req.Input("name")
}
Dependency Injection & Route Parameters
If your controller method is also expecting input from a route parameter you should list your route parameters after the request dependencies. For example, you can access your route parameter name like so:
route.Put("/user/{name}", func(req *context.Request, name string) *context.Response {
//
})
Request Path & Method
The path method returns the request's path information. So, if the incoming request is targeted at http://domain.com/foo/bar, the path method will return foo/bar:
uri := req.GetPath()
The method method will return the HTTP verb for the request.
method := req.GetMethod();
Retrieving Cookies From Requests
name, _ := request.Cookie("name")
HTTP Response
an HTTP Response Must implement the *context.Response interface
Creating Responses
a simple strings or json Response:
thinkgo.Text("Hello ThinkGo !")
thinkgo.Json(map[string]string{
"message": "pong",
})
Attaching Cookies To Responses
response.Cookie("name", "alice")
Redirects
route.Get("/redirect", func(request *context.Request) *context.Response {
return context.Redirect("https://www.google.com")
})
View
Specify the views directory before running the app:
view.ParseGlob("/path/to/views/*")
views are stored in the views directory, A simple view might look something like this:
views/layout.html like this:
{{ define "layout" }}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{ .Title }}</title>
</head>
<body>
{{ template "content" .}}
</body>
</html>
{{ end }}
views/tpl.html like this:
{{ define "content" }}
<h2>{{ .Message }}</h2>
{{ end }}
{{ template "layout" . }}
we may return it using the Render function like so:
route.Get("/tpl", func(request *context.Request) *context.Response {
data := map[string]interface{}{"Title": "ThinkGo", "Message": "Hello ThinkGo !"}
return view.Render("tpl.html", data)
})
HTTP Session
When the app starts, you need to register the session handler.
think.RegisterHandler(app.NewSessionHandler)
ThinkGo ships with several great drivers out of the box:
- cookie - sessions are stored in cookies
- file - sessions are stored in files.
Using The Session
retrieving Data like this:
request.Session().Get("user")
storing Data like this:
request.Session().Set("user", "alice")
Adding Custom Session Drivers
Your custom session driver should implement the Handler.
type Handler interface {
Read(id string) string
Write(id string, data string)
}
Once your driver has been implemented, you are ready to register it:
import "github.com/forgoer/thinkgo/session"
session.Extend("my_session", MySessionHandler)
Logging
The logger provides the eight logging levels defined in RFC 5424: emergency, alert, critical, error, warning, notice, info and debug.
Basic Usage
import "github.com/forgoer/thinkgo/log"
log.Debug("log with Debug")
log.Info("log with Info")
log.Notice("log with Notice")
log.Warn("log with Warn")
log.Error("log with Error")
log.Crit("log with Crit")
log.Alert("log with Alert")
log.Emerg("log with Emerg")
Log Storage
Out of the box, ThinkGo supports writing log information to daily files, the console.
For example, if you wish to use daily log files, you can do this:
import (
"github.com/forgoer/thinkgo/log"
"github.com/forgoer/thinkgo/log/handler"
"github.com/forgoer/thinkgo/log/record"
)
fh := handler.NewFileHandler("path/to/thinkgo.log", record.INFO)
log.GetLogger().PushHandler(fh)
Cache
ThinkGo Cache Currently supports redis, memory, and can customize the store adapter.
Basic Usage
import (
"github.com/forgoer/thinkgo/cache"
"time"
)
var foo string
// Create a cache with memory store
c, _ := cache.Cache(cache.NewMemoryStore("thinkgo"))
// Set the value
c.Put("foo", "thinkgo", 10 * time.Minute)
// Get the string associated with the key "foo" from the cache
c.Get("foo", &foo)
Retrieve & Store
Sometimes you may wish to retrieve an item from the cache, but also store a default value if the requested item doesn't exist. For example, you may wish to retrieve all users from the cache or, if they don't exist, retrieve them from the callback and add them to the cache. You may do this using the Remember method:
var foo int
cache.Remember("foo", &a, 1*time.Minute, func() interface{} {
return "thinkgo"
})
