Express.js - 过滤URL中的mongodb id [英] Express.js - Filter a mongodb id in the URL

问题描述

这个问题的灵感来源于这篇文章但是在我的情况下，我需要过滤MongoId。

This question inspired by this post but in my case I need to filter MongoId. Is it possible to make filtering easily that the below because I need use it in each route?

app.post('/:mongoId(^[0-9a-fA-F]{24}$)', function(req, res){
   // Send query based on mongoId
}

推荐答案

你几乎在那里，只是不要添加 ^ 和 $ 锚点，而大写的 AF 范围甚至不需要，因为Express似乎匹配不区分大小写：

You're almost there, just don't add the ^ and $ anchors. And the uppercase A-F range isn't even necessary since Express seems to match case-insensitive:

app.post('/:mongoId([0-9a-f]{24})', function(req, res){
  var id = req.param('mongoId');
  ...
});
