我如何使Express.js与路径/1.1.1和/ login区分开来?
我使用以下代码: p>
app.get('/:x?。:y?。:z?',function(req,res){ ... app.get('/ login',function(req,res){解决方案
路由按照添加的顺序执行,所以如果你希望你的登录路由优先,先定义它。 >
否则,如果您想根据路由进行决策,可以从处理程序内调用next()函数,如下所示:
app.get('/:x?。:y?。:z?',function(req,res,next){//< == note 'next'参数如果(!req.params.x&!req.params.y&!req.params.z){ next(); // pass控制到下一个路由处理程序} ... }从快速指南:对于具有相同路径定义的几条路线也是如此,它们将被简单地执行,直到不调用next()并决定响应。
How can I make Express.js distinguish from the paths "/1.1.1" and "/login" ?
I am using the following code:
app.get('/:x?.:y?.:z?', function(req, res){ ... app.get('/login', function(req, res){解决方案
Routes are executed in the order they are added. So if you want your login route to take precedence, define it first.
Otherwise, in cases where you want to make decisions based on route, you can call the next() function from inside your handler like this:
app.get('/:x?.:y?.:z?', function(req, res, next){ // <== note the 'next' argument if (!req.params.x && !req.params.y && !req.params.z) { next(); // pass control to the next route handler } ... }From the Express guide: "The same is true for several routes which have the same path defined, they will simply be executed in order until one does not call next() and decides to respond."
