Parse a URL with memoization.
用缓存解析 URL
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
这是一个在 npm 网站可用的 Node.js 模块，通过键入
npm install命令来安装
$ npm install parseurlvar parseurl = require('parseurl')Parse the URL of the given request object (looks at the req.url property)
and return the result.
解析 request 对象的 URL（查看
req.url属性），并返回结果
The result is the same as url.parse in Node.js core.
这个结果和 node.js 中的
url.parse类似
Calling this function multiple times on the same req where req.url does
not change will return a cached parsed object, rather than parsing again.
当
req.url没有改变时，在同一个req上调用这个函数多次，会返回一个已经解析过的缓存的对象，而不是再一次进行解析
Parse the original URL of the given request object and return the result.
解析 request 对象的原始 URL 并返回结果
This works by trying to parse req.originalUrl if it is a string, otherwise
parses req.url.
如果他是个字符串就尝试解析
req.originalUrl，否则解析req.url
The result is the same as url.parse in Node.js core.
这个结果跟 node.js 中的
url.parse类似
Calling this function multiple times on the same req where req.originalUrl
does not change will return a cached parsed object, rather than parsing again.
当
req.originalUrl没有改变时，在同一个req上调用这个函数多次，会返回一个已经解析过的缓存的对象，而不是再一次进行解析
