How to solve the problem that the browser access path does not prompt for download but displays a new page-JS Tutorial-php.cn

This time I will show you how to solve the problem of displaying a new page when the browser access path does not prompt for downloading.What are the precautions? Here are Let’s take a look at practical cases.

Taking the nodejs code as an example, I will jump to the browser's built-in playback page when accessing "/video".
When accessing "/frag_bunny.mp4", a download prompt will pop up.

Code:

var http = require('http');var fs = require('fs');var url = require('url');var routes = {//<====路由 "/video"(request, response) { fs.readFile("frag_bunny.mp4", 'binary', function (err, data) { if (err) { console.log(err); response.writeHead(500, { 'Content-Type': 'text/html' }); } else { response.writeHead(200, { 'Content-Type': 'video/mp4' });//<====mp4标识 response.write(data, 'binary'); } response.end(); }); }, "/frag_bunny.mp4"(request, response) { fs.readFile("frag_bunny.mp4", 'binary', function (err, data) { if (err) { console.log(err); response.writeHead(500, { 'Content-Type': 'text/html' }); } else { response.writeHead(200, { 'Content-Type': 'application/octet-stream' });//<====文件流标识 response.write(data, 'binary'); } response.end(); }); }, "/"(request, response) { response.writeHead(200, { 'Content-Type': 'text/html' }); response.write(` 打开页面显示播放界面 
 打开页面提示下载 `); response.end(); }, "/404"(request, response) { response.writeHead(404, { 'Content-Type': 'text/html' }); response.write("404"); response.end(); } }// 创建服务器http.createServer(function (request, response) { // 解析请求，包括文件名 var pathname = url.parse(request.url).pathname; // 输出请求的文件名 console.log("Request for " + pathname + " received."); route = routes[pathname] if (route) { route(request, response); } else { routes["/404"](request, response); } }).listen(8889);
