vue cli3.0+node

• 利用node-express做中间层，解决跨域问题 引入app.js

1.在package.json配置环境变量：
在windows系统下 执行环境变量需要install cross-env 并在变量前赋值

2. ecosystem.config.js

module.exports = {
  apps: [
    {
      name: 'PYCMS-DEV',
      script: 'app.js',
      // Options reference: https://pm2.io/doc/en/runtime/reference/ecosystem-file/
      args: '',
      instances: 1,
      autorestart: true,
      watch: false,
      max_memory_restart: '1G',
      env: {
        NODE_ENV: 'development'
      },
    },
    {
      name: 'PYCMS-TEST',
      script: 'app.js',
      // Options reference: https://pm2.io/doc/en/runtime/reference/ecosystem-file/
      args: '',
      instances: 1,
      autorestart: true,
      watch: false,
      max_memory_restart: '1G',
      env: {
        NODE_ENV: 'test'
      },
    },
    {
      name: 'PYCMS-ONLINE',
      script: 'app.js',
      // Options reference: https://pm2.io/doc/en/runtime/reference/ecosystem-file/
      args: '',
      instances: 1,
      autorestart: true,
      watch: false,
      max_memory_restart: '1G',
      env: {
        NODE_ENV: 'production'
      },
    }
  ]
};

3. app.js

const fs = require('fs');
const path = require('path');
const history = require('connect-history-api-fallback');  //vue router history 模式
const routes = require('./server/routes/index');
const share = require('./server/routes/share');
const wx = require('./server/routes/wx');
const express = require('express');
const cookieParser = require('cookie-parser');
const app = express();
app.use(cookieParser());

console.log('process.env', process.env.NODE_ENV);

//todo: create server config
const config = require('./server/config');

app.set('views', './server/views');
app.set('view engine', 'ejs');

app.use('/', routes);          //静态页面
app.use('/share', share);  //分享
app.use('/wx', wx);            //微信页面


//vue 静态资源路径
app.use(express.static(path.resolve(__dirname, 'server/static')));

//vue router history 模式
app.use(history({
  verbose: true,
  index: '/'
}));

//vue router history 模式错误路径统一跳转至index.html;
app.get("/", function(req, res) {
  try {
    //跳转默认首页
    const existed = fs.existsSync(path.join(__dirname, "dist/index.html"),fs.F_OK);
    if(existed) {
      res.sendFile(path.join(__dirname, "dist/index.html"));
    } else {
      //项目编译过程中dist目录尚未生成时跳转值服务器维护提示页
      res.sendFile(path.join(__dirname, "server/static/server-error.html"));
    }
  } catch (e) {
    res.sendFile(path.join(__dirname, "server/static/server-error.html"));
  }
});

/*app.get('*', function(req, res) {
  const html = fs.readFileSync(path.resolve(__dirname, './dist/index.html'), 'utf-8')
  res.send(html)
});*/

//测试服务器部署开发环境（用于调试后端开发接口）监听4000端口，测试及线上环境监听5000端口
app.listen(config.ports[process.env.NODE_ENV]);

4.router-index.js

const path = require("path");

const routes = require('express').Router();

/**
 * 定义跳转特殊静态页面：
 */
//App嵌入页面
routes.get('/adjust_rule', function (req, res) {
  res.sendFile(path.join(__dirname, "../../server/static/rule.html"));
});


module.exports = routes;
