URI貌似属于比较基本的一种协议，虽然我经常记不住它的具体格式。今天在WIKI上看到一个比较详细的格式描述，所以copy下来保留，仅此而已。

<scheme name> : <hierarchical part> [ ? <query> ] [ # <fragment> ]

The following figure displays two example URIs (foo://username:password@example.com:8042/over/there/index.dtb?type=animal&name=narwhal#nose andurn:example:animal:ferret:nose) and their component parts. (The examples are derived from RFC 3986 — STD 66, chapter 3).

  foo://username:password@example.com:8042/over/there/index.dtb?type=animal&name=narwhal#nose
