Deno上传文件
视频讲解 https://www.bilibili.com/video/BV1BT4y1E7Nh/?p=6
我们一起来完成以下步骤:
- 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
#controllers/controller.ts
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;
#routers/index.ts
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;
#views/upload-page.ejs
<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>
#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 })
