Remove url.parse / 删除已弃用的对 url.parse 的调用

[mhornbacher]

这个问题处理了NodeJS中的下列弃用警告，通过使用URL类而不是全局解析方法来处理。两者都有pathname属性，这是这里所需的。(This handles the following deprecation in NodeJS by using the URL class rather than the global parse method which both have the pathname attribute which is what is required here.)

[DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for url.parse() vulnerabilities.

修复 #149 (Fixes #149)
