关于golang:重写micro网关添加鉴权模块

micro网关鉴权

这个鉴权无非就是通过中间件来管制拜访，须要重写micro代码

咱们只须要编写一个plugin函数，并注册到micro外面即可实现申请中间件的性能

代码如下

package mainimport (   "fmt"   "github.com/micro/cli"   "github.com/micro/micro/cmd"   "github.com/micro/micro/plugin"   "net/http")func JWTAuthWrapper() plugin.Handler {   return func(h http.Handler) http.Handler {      return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {         fmt.Println("解决http")         h.ServeHTTP(w, r)      })   }}func jwtPlugin() plugin.Plugin {   //jwt 鉴权   return plugin.NewPlugin(      plugin.WithName("auth"),      plugin.WithHandler(         JWTAuthWrapper()),      //参数      plugin.WithFlag(cli.StringFlag{         Name:   "consul_address",         Usage:  "consul address for K/V",         EnvVar: "CONSUL_ADDRESS",         Value:  "127.0.0.1:8500",      }),      plugin.WithInit(func(ctx *cli.Context) error {         fmt.Println("初始化")         return nil      }))}func main() {   _ = plugin.Register(jwtPlugin())   cmd.Init()}
