服务端ssr渲染，原理是模版引擎+渲染数据，处理完成后返回给客户端。 node中有个第三方库ejs，可以处理模版引擎的渲染。模版引擎： <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <%arr.forEach(a => {%> <li><%=a%></li> <%})%> </body> </html> ejs渲染： let ejs = require('ejs'); let fs = require('fs'); let path = require('path'); let data = {arr: [1,2,3]}; // 编码格式必须有 let templateStr = fs.readFileSync(path.resolve(__dirname, './index.html'), 'utf-8'); let str = ejs.render(templateStr
