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~\(≧▽≦)/~啦啦啦~
