使用urlManager配置规则来美化url问题 [ 未指定版本 ]

URL manager 按照 rules 内规则声明的先后顺序依次检查，找到第一个匹配的规则后就会使用该规则，之后的所有规则，不管是否匹配，都会忽略。

the URL manager examines the rules in the order they are declared and looks for the first rule that matches the requested URL. The matching rule is then used to parse the URL into a route and its associated parameters.

URL Rules

你声明的这两条规则中，

'article' => 'article/index'

是多余的，因为 index 是 default action, 可以自动识别。
