Deno上传文件

视频讲解 https://www.bilibili.com/video/BV1BT4y1E7Nh/?p=6

沿用之前的工程代码
创建上传页面和响应的 controller
添加上传文件功能
测试

const {cwd} = Deno;

class Controller {static async getData(ctx: any){
        //cwd 获取当前工程目录 
        // 注意 '！== `
        ctx.render(`${cwd()}/views/index.ejs`,{
            title:"Testing",
            data:{name:"deepincoding"}
        }); 
    }
    static async uploadPage(ctx: any){ctx.render(`${cwd()}/views/upload-page.ejs`);
    }

    static async uploadAction(ctx: any){
        // 我们这里不返回页面，而是返回上传文件的信息
        ctx.response.body = ctx.uploadedFiles;
    }
    
}

export default Controller;

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


const router = new Router();

router.get("/",Controller.getData);

router.get("/uploadPage",Controller.uploadPage);

router.post("/uploadAction", upload('uploads', ['jpg','png'], 20000000, 10000000, true, false, true),Controller.uploadAction);

export default router;

<body>
<form id="yourFormId" enctype="multipart/form-data" action="/uploadAction" method="post">
    <input type="file" name="file1" multiple><br>
    <input type="submit" value="Submit">
  </form>
</body>


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})
