本文介绍了Node.js / Express路由与获取参数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

假设我有这样的路由:

  app.get('/ documents / format / type',function(req,res){
var format = req.params.format,
type = req.params.type;
});

所以如果我提出如

  http:// localhost:3000 / documents / json / mini 

我的格式和类型变量将分别为'json'和'mini',但如果我提出请求,如

  http: // localhost:3000 / documents / mini / json 

不。所以我的问题是:如何以不同的顺序获取相同的变量?

解决方案

你的路由不行,应该这样(用':')

  app.get('/ documents /:format /:type' req,res){
var format = req.params.format,
type = req.params.type;
});

不幸的是你不能互换参数顺序。
有关 req.params (和 req.query )的更多信息,请查看api参考 here


Let's say I have get route like this:

app.get('/documents/format/type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

So if I make request like

http://localhost:3000/documents/json/mini

in my format and type variables will be 'json' and 'mini' respectively, but if I make request like

http://localhost:3000/documents/mini/json

not. So my question is: how can I get the same variables in different order?

解决方案

Your route isn't ok, it should be like this (with ':')

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.
