Sure, just add a middleware function to modify it. For example:
当然，只需添加一个中间件功能来修改它。例如：
app.use(function(req, res, next) {
if (req.url.slice(-1) === '/') {
req.url = req.url.slice(0, -1);
}
next();
});
This function removes the trailing slash from all incoming request URLs. Note that in order for this to work, you will need to place it before the call to app.use(app.router).
此函数从所有传入的请求 URL 中删除尾部斜杠。请注意，为了使其工作，您需要将其放置在调用app.use(app.router).

A good idea should be to update the pathtoo. My method suggestions:
一个好主意应该是更新path太。我的方法建议：
app.use(function(req, res, next) {
console.log("request", req.originalUrl);
const removeOnRoutes = '/not-wanted-route-part';
req.originalUrl = req.originalUrl.replace(removeOnRoutes,'');
req.path = req.path.replace(removeOnRoutes,'');
return next();
});
By this way /not-wanted-route-part/userswill became /users
这样/not-wanted-route-part/users就会变成/users
