嵌入式参数

rk-boot 中，可以使用 embed.FS 给 rk-boot 提供 boot.yaml 等静态文件。

概述

目前，用户可以把 Swagger UI 参数文件, API Docs 参数文件和 boot.yaml 文件通过 embed.FS 传递给 rk-boot.

快速开始

1.安装

$ go get github.com/rookie-ninja/rk-boot/v2
$ go get github.com/rookie-ninja/rk-mux

2.创建 boot.yaml

mux:
  - name: greeter
    port: 8080
    enabled: true

3.创建 main.go

package main

import (
  "context"
  _ "embed"
  "fmt"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-mux/boot"
  "github.com/rookie-ninja/rk-mux/middleware"
  "net/http"
)

//go:embed boot.yaml
var bootRaw []byte

func main() {
  // Create a new boot instance.
  boot := rkboot.NewBoot(rkboot.WithBootConfigRaw(bootRaw))

  // Get MuxEntry
  muxEntry := rkmux.GetMuxEntry("greeter")
  // Use *mux.Router adding handler.
  muxEntry.Router.NewRoute().Path("/v1/greeter").HandlerFunc(Greeter)

  // Bootstrap
  boot.Bootstrap(context.TODO())

  boot.WaitForShutdownSig(context.TODO())
}

func Greeter(writer http.ResponseWriter, req *http.Request) {
  rkmuxmid.WriteJson(writer, http.StatusOK, &GreeterResponse{
    Message: fmt.Sprintf("Hello %s!", req.URL.Query().Get("name")),
  })
}

type GreeterResponse struct {
  Message string
}

4.启动 main.go

$ go run main.go
2022-05-10T12:08:39.562+0800    INFO    boot/mux_entry.go:687   Bootstrap muxEntry      {"eventId": "471962da-2fdb-4154-8bc6-a31a8a4637cd", "entryName": "greeter", "entryType": "MuxEntry"}

elapsedNano=93582
timezone=CST
ids={"eventId":"471962da-2fdb-4154-8bc6-a31a8a4637cd"}

payloads={"muxPort":8080}
counters={}

EOE

5.验证

$ curl "localhost:8080/v1/greeter?name=rk-dev"
{"Message":"Hello rk-dev!"}%

Swagger UI 与 Docs UI

我们同时还可以让 rk-boot 使用 embedFS 读取 swagger 相关的参数文件。

1.已存在的 Swagger JSON 文件

├── docs
│   ├── swagger.json
│   └── swagger.yaml

2.创建 boot.yaml

mux:
  - name: greeter
    port: 8080
    enabled: true
    sw:
      enabled: true
    docs:
      enabled: true

3.创建 main.go

package main

import (
    "context"
    _ "embed"
    "fmt"
    "github.com/rookie-ninja/rk-boot/v2"
    "github.com/rookie-ninja/rk-mux/boot"
    "github.com/rookie-ninja/rk-mux/middleware"
    "net/http"
)

//go:embed boot.yaml
var bootRaw []byte

//go:embed ../../..
var docsFS embed.FS

//go:embed docs
var swFS embed.FS

func init() {
    rkentry.GlobalAppCtx.AddEmbedFS(rkentry.SWEntryType, "greeter", &docsFS)
    rkentry.GlobalAppCtx.AddEmbedFS(rkentry.DocsEntryType, "greeter", &swFS)
}

func main() {
    // Create a new boot instance.
    boot := rkboot.NewBoot(rkboot.WithBootConfigRaw(bootRaw))

    // Get MuxEntry
    muxEntry := rkmux.GetMuxEntry("greeter")
    // Use *mux.Router adding handler.
    muxEntry.Router.NewRoute().Path("/v1/greeter").HandlerFunc(Greeter)

    // Bootstrap
    boot.Bootstrap(context.TODO())

    boot.WaitForShutdownSig(context.TODO())
}

func Greeter(writer http.ResponseWriter, req *http.Request) {
    rkmuxmid.WriteJson(writer, http.StatusOK, &GreeterResponse{
        Message: fmt.Sprintf("Hello %s!", req.URL.Query().Get("name")),
    })
}

type GreeterResponse struct {
    Message string
}
