快速入门

安装Tango：

go get gitea.com/lunny/tango

一个经典的Tango例子如下：

package main

import (
    "errors"
    "gitea.com/lunny/tango"
)

type Action struct {
    tango.JSON
}

func (Action) Get() interface{} {
    if true {
        return map[string]string{
            "say": "Hello tango!",
        }
    }
    return errors.New("something error")
}

func main() {
    t := tango.Classic()
    t.Get("/", new(Action))
    t.Run()
}

然后在浏览器访问http://localhost:8000, 将会得到一个json返回

{"say":"Hello tango!"}

如果将上述例子中的 true 改为 false, 将会得到一个json返回

{"err":"something error"}

这段代码因为拥有一个内嵌的tango.JSON，所以返回值会被自动的转成Json
