- 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

- 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'
},
}
]
};
- 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;
