【Javascript】【权限控制】NodeJS允许跨域请求

在nodejs的启动文件里加上如下代码

let express = require("express");
let app = express();
app.use(express.static("web-resource"));
app.use("*", (req, res, next) => {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "*");
    res.header("Access-Control-Allow-Methods", "*");
    next();
});
app.listen(8003, () => {
    console.log("NodeJS File Service Start");
    console.log("Home：http://localhost:8003/html/home.html");
});

express是一个文件服务发布模块，如果没有，自己通过命令行安装即可
