使用egg.js发送jwt

下载jwt        配置jwt

pnpm i egg-jwt

 plugin.js

/** @type Egg.EggPlugin */
module.exports = {
  jwt:{
    enable:true,
    package:'egg-jwt'
  }
};

config.default.js

config.jwt = {
    secret:"hakurei77"    //密钥
  }

创建中间层

        app -> middleware

//检查token
module.exports = (options) => {
    return async function jwtErr(ctx, next) {
      const token = ctx.request.header.authorization;
      let decode = '';
      if (token) {
        try {
          // 解码token
          decode = ctx.app.jwt.verify(token, options.secret);
          await next();
          console.log('decode======>',decode);
        } catch (error) {
          ctx.status = 401;
          ctx.body = {
            message: error.message,
          };
          return;
        }
      } else {
        ctx.status = 401;
        ctx.body = {
          message: '没有token',
        };
        return;
      }
    };
  }

 Controller层

async ...() {
   const { ctx , app } = this;
   const result = await             
   this.ctx.service.userService....(this.ctx.request.body ,app);
   ctx.body = result
}

Service层

。。。
const token = app.jwt.sign({
    UserName: user.UserName,
    Password: user.Password
},app.config.jwt.secret,{expiresIn:"15s"})    //里面放持续时间
result = {
    "code": 200,
    "msg": "成功",
    "data": {
        "TOKEN": token
    }
}

路由层

module.exports = app => {
  const { router, controller,middleware } = app;
  const jwtErr = middleware.jwtErr(app.config.jwt)

  router.post("/main" ,jwtErr ,controller.userController.abc)
};
