micro网关鉴权
这个鉴权无非就是通过中间件来控制访问,需要重写micro代码
我们只需要编写一个plugin函数,并注册到micro里面即可实现请求中间件的功能
代码如下
package main
import (
"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("处理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()
}
