路由

本包仅用于 http 路由匹配，使用场景为路径参数解析。例如： /apis/{group}/{version}.

动机

原使用的 gin 框架，其路由匹配使用的前缀树实现，匹配速度较快。但是在使用过程中有许多的限制， 例如不能实现确定路径与通配路径同时存在（/api/core/v1 与 /{group}/{version}同时存在），相同前缀的路由无法被注册（/app1, /app2）. 无法在路径中注册带":"的路由（google api 中的自定义方法），以及其他复杂的匹配问题。

语法

  • 使用 '{' 与'}'定义变量匹配，其间的字符作为变量名称。可以使用 "{}"定义无名称变量。
  • 使用 '*' 作为最后一个字符表示向后匹配。/{name}*,将使 name 向后匹配。
  • 其他字符作为常规字符进行匹配。

路由匹配

固定匹配

  • /api/v1/

    • ✅/api/v1/
    • ❌/api/v1
    • ❌/api/v11
    • ❌/api/v789

  • /api/v1*

    • ✅/api/v1/
    • ✅/api/v1
    • ✅/api/v11
    • ✅/api/v11/hello
    • ✅/api/v1/hello
    • ❌/api/v789

  • /api/*1 (非后缀的*作为普通字符对待)

    • ✅/api/*1
    • ❌/api/v1
    • ❌/api/v/1
变量匹配

  • /api/{version}

    • ✅/api/*1;version=*1
    • ✅/api/v1;version=v1
    • ❌/api/v/1
    • ❌/api/v1/

  • /api/v{version}

    • ✅/api/v1;version=1
    • ✅/api/vhello;version=hello
    • ✅/api/v*1;version=*1
    • ❌/api/v1/
    • ❌/api/v/1

  • /api/v{version}*

    • ✅/api/v1;version=1
    • ✅/api/vhello/world;version=hello/world
    • ✅/api/v/1;version=/1
    • ❌/apis/v1

  • /api/v{version}/{group}

    • ✅/api/v1/;version=1,group=
    • ✅/api/vhello/world;version=hello,group=world
    • ❌/api/v1;version=1
    • ✅/api/v/1;version=,group=1

  • /person/{firstname}-{lastname}

    • ✅/person/jack-ma;firstname=jack,lastname=ma
    • ❌/person/jack-ma/
    • ❌/person/jackma
向后匹配

  • /prefix/{path}*

    • ✅/prefix/abc;path=abc
    • ✅/prefix/abc/def;path=abc/def
    • ❌/prefixabc;

  • /prefix*

    • ✅/prefix/abc
    • ✅/prefixabc/def
    • ❌/pref/jackma
混合使用

若同时定义如下路由：

  • /api/v{version}/{group}
  • /api/v1/{group}
  • /api/v1/core

则若同时满足上述条件下，路径参数少的匹配被选中。

举例：

  • 请求/api/v1/core,则匹配中 /api/v1/core;
  • 请求/api/v1/hello,则匹配中 /api/v1/{group};
  • 请求/api/v2/hello,则匹配中 /api/v{version}/{group};
