Deno 几种常用的传参方式

视频讲解:

https://www.bilibili.com/video/BV1BT4y1E7Nh/?p=8

我们一起来完成以下步骤:

1. 以key-value方式传参

2. 以value方式传参

3. 使用oak Helpers 接受传参

4. body 传参

5. header 传参

#controllers/controller.ts

import { getQuery } from "https://deno.land/x/oak/helpers.ts";
const { cwd } = Deno;

class Controller {
 static async hello(ctx: any){  //cwd获取当前工程目录   //注意 ' !== `  ctx.render(`${cwd()}/views/index.ejs`,{  title:"Testing",  data:{name:" Deepincoding"}  });  }   //key-value 方式传参  static async searchParams(ctx: any){  var id = ctx.request.url.searchParams.get("id");  var name = ctx.request.url.searchParams.get("name");  ctx.response.body= {id:`${id}`,name:`${name}`}  }   //value 方式传参  static async params(ctx: any){  var id = ctx.params.id;  var name = ctx.params.name;  ctx.response.body= {id:`${id}`,name:`${name}`}  }   //oak Helpers 接受参数  static async helper(ctx: any){  var paramsValue = getQuery(ctx, { mergeParams: true });  ctx.response.body= paramsValue;  }   //body 传参  static async body(ctx: any){  var bodyValue = await ctx.request.body();  ctx.response.body= bodyValue.value;  }   //header 传参  static async header(ctx: any){  var id = ctx.request.headers.get("id");  var name = ctx.request.headers.get("name");  ctx.response.body= {id:`${id}`,name:`${name}`}  }  }  export default Controller;  

#routers/index.ts

import { Router } from "https://deno.land/x/oak/mod.ts";
import Controller from "../controllers/Controller.ts";

const router = new Router();

router.get("/",Controller.hello);  router.get("/searchParams",Controller.searchParams); router.get("/params/:id/:name",Controller.params);  router.get("/helper/:id/:name",Controller.helper); router.get("/helper",Controller.helper);  router.post("/body",Controller.body); router.post("/header",Controller.header);   export default router;  

#main.ts

import { Application } from "https://deno.land/x/oak/mod.ts"
import {viewEngine,engineFactory,adapterFactory} from "https://deno.land/x/view_engine/mod.ts";
import router from "./routers/index.ts";
 const ejsEngine = engineFactory.getEjsEngine(); const oakAdapter = adapterFactory.getOakAdapter();  const app = new Application(); app.use(viewEngine(oakAdapter,ejsEngine)); app.use(router.routes()); app.use(router.allowedMethods());  await app.listen({port: 8000 })
