express中的路径区别

请求的url:http://localhost:3000/api/article/upload?q=1000&n=tom
请求方法:post
console.log('hostname==='+req.hostname);
console.log('protocol==='+req.protocol);
console.log('port==='+req.app.get('port'));
console.log('originalUrl==='+req.originalUrl);
console.log('baseUrl==='+req.baseUrl);//通过app.use挂载的路径
console.log('path==='+req.path);
console.log('url==='+req.url);

//打印结果

hostname===localhost
protocol===http
port===3000
originalUrl===/api/article/upload?q=1000&n=tom
baseUrl===/api/article
path===/upload
url===/upload?q=1000&n=tom
