nodejs统计对应ip地址的对某个接口的请求次数

Question

exports.prodform=function (req, res) {    let phone=req.body.phone;    let province=req.body.province;    let city=req.body.city;    let district=req.body.district;    let detailaddress=req.body.detailaddress;    let data= " 手机号码: "+phone+" 地址: "+province+city+district+detailaddress+'\r\n';    let json={        "success":true,    }    fs.writeFile("订单.txt",data,{flag: 'a'},function(err,result) {        if(err) throw err;        console.log('成功');    })    res.json(json);}对于上面这个接口，我如何统计不同ip地址对其的访问次数呢？

Answer 1

定义一个全局变量
例如 ipList = {};

在exports.prodform里面加入下面的代码：

let ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;

if(!!ipList[ip]){

    ipList[ip] = ipList[ip]+1;

}else{

    ipList[ip] = 1;

}

或者使用redis吧
