烂翻译系列之Iris——API示例之路径参数

Parameters in path  路径参数

func main() {
    app := iris.Default()

    // This handler will match /user/john but will not match /user/ or /user
    app.Get("/user/{name}", func(ctx iris.Context) {
        name := ctx.Params().Get("name")
        ctx.Writef("Hello %s", name)
    })

    // However, this one will match /user/john/ and also /user/john/send
    // If no other routers match /user/john, it will redirect to /user/john/
    app.Get("/user/{name}/{action:path}", func(ctx iris.Context) {
        name := ctx.Params().Get("name")
        action := ctx.Params().Get("action")
        message := name + " is " + action
        ctx.WriteString(message)
    })

    // For each matched request Context will hold the route definition
    app.Post("/user/{name:string}/{action:path}", func(ctx iris.Context) {
        ctx.GetCurrentRoute().Tmpl().Src == "/user/{name:string}/{action:path}" // true
    })

    app.Listen(":8080")
}
