node 撸一个服务器

var http = require('http');

var server = http.createServer();

var datas = {
    "grade": "1",
    "name": "企业负责人"
}

server.listen('9999','172.100.101.201');

server.on('listening',function(){
    console.log('服务启动');
})

server.on('error', function(err) {
    console.log(err);
});

server.on('request', function(request, response) {

    console.log(new Date() + '有请求了...');

    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setHeader("Access-Control-Allow-Methods", "POST");
    response.setHeader("Access-Control-Allow-Headers", "x-requested-with , content-type");
    response.end(JSON.stringify(datas));

});
