Node服务端响应状态码实现重定向

302为临时重定向，301为永久重定向

var http = require("http");

var server = http.createServer();

server.on("request", function (req, res) {
    if (req.url === "/") {
        res.statusCode = 302; 
        res.setHeader("Location", "https://www.baidu.com/");
        res.end();
    }
})

server.listen(3000, function () {
    console.log("server is running on port 3000");
})
