# 1. 创建⼴告
新建router/advertise.js，代码如下：
// router/advertise.js
const Router = require("@koa/router");
const AdvertiseController = require("../controller/AdvertiseController.js");
const jwtAuth = require("koa-jwt");
const config = require("../config/index.js");
const router = new Router();
// 创建广告
router.post("/advertise", jwtAuth({
secret: config.security.secretKey
}), AdvertiseController.createAdvertise);
module.exports = router;

在app.js中，注册对应的路由，如下：
// app.js
// ...
// 路由的引入
const user = require("./router/user.js")
const admin = require("./router/admin.js")
const category = require("./router/category.js")
const advertise = require("./router/advertise.js")
// ...
// 注册广告模块路由
app.use(advertise.routes());
advertise.allowedMethods();
// ...

const AdvertiseModel = require("../models/AdvertiseModel");
const {
advertiseValidator
} = require("../validators/advertise");
const res = require("../core/helper");
class ReplyController {
// 创建广告
static async createAdvertise(ctx, next) {
advertiseValidator(ctx);
const {
title
} = ctx.request.body;
let hasAdvertise = await AdvertiseModel.findOne({
title
});
if (hasAdvertise) {
throw new global.errs.Existing("广告已存在");
}
let advertise = await AdvertiseModel.create(ctx.request.body);
ctx.body = res.json(advertise);
}
}
module.exports = ReplyController;
