javascript使用npm安装request-ip包const requestIp=require('request-ip');// 在中间件处理器中const ipMiddleware=(req, res, next)=> { const clientIp=requestIp.getClientIp(req); next();};// 在本地运行时，您将看到127.0.0.1

npm install request-ipconst requestIp = require('request-ip');

// inside middleware handler
const ipMiddleware = function(req, res, next) {
const clientIp = requestIp.getClientIp(req);
next();
};

// on localhost you'll see 127.0.0.1 if you're using IPv4
// or ::1, ::ffff:127.0.0.1 if you're using IPv6
