Vue前后端不同端口的实现方法

前端Vue 8080端口,后端Node.js 8085端口 主要记录下前后端不同端口遇到的问题
1、写服务器端程序,我的在(node_proxy/index.js)下
app.all('*', function (req, res, next) { res.header('Access-Control-Allow-Origin', req.headers.origin || '*'); res.header('Access-Control-Allow-Headers', 'Content-Type,Content-Length, Authorization,\'Origin\',Accept,X-Requested-With'); res.header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE'); res.header('Access-Control-Allow-Credentials', true); res.header('X-Powered-By', ' 3.2.1'); res.header('Content-Type', 'application/json;charset=utf-8'); if (req.method === 'OPTIONS') { res.sendStatus(200); } else { next(); } });
这段代码很重要,要是没有的话会出现 No 'Access-Control-Allow-Origin' header is present on the requested resource 错误。
2、在前端用axios写get请求处理程序,写在了Card模板下
mounted(){ axios.get(HOST) .then(response => { this.sed = response.data.data; }) }
3、在config/index.js下配置proxyTable:
proxyTable: { '/seller': { target: 'http://localhost:8085', changeOrigin: true, pathRewrite: { '^/seller': '/seller' } } },
4、分别启动前后端,OK~\(?R??Q)/~啦啦啦~
