Node.js/Express routing with get params
提问by Erik
Let's say I have get route like this:
假设我有这样的路线：
app.get('/documents/format/type', function (req, res) {
var format = req.params.format,
type = req.params.type;
});
So if I make request like
所以如果我提出请求
http://localhost:3000/documents/json/mini
in my format and type variables will be 'json' and 'mini' respectively, but if I make request like
在我的格式和类型变量中将分别是 'json' 和 'mini'，但是如果我提出这样的请求
http://localhost:3000/documents/mini/json
not. So my question is: how can I get the same variables in different order?
不是。所以我的问题是：如何以不同的顺序获得相同的变量？

Your route isn't ok, it should be like this (with ':')
你的路线不行，应该是这样的（带':'）
app.get('/documents/:format/:type', function (req, res) {
var format = req.params.format,
type = req.params.type;
});
Also you cannot interchange parameter order unfortunately.
For more information on req.params(and req.query) check out the api reference here.
不幸的是，您也无法交换参数顺序。有关req.params（和req.query）的更多信息，请查看此处的 api 参考。

For Query parameters like domain.com/test?format=json&type=miniformat, then you can easily receive it via - req.query.
对于像domain.com/test?format=json&type=mini格式这样的查询参数，那么您可以通过 - req.query 轻松接收它。
app.get('/test', function(req, res){
var format = req.query.format,
type = req.query.type;
});
