1. enablePrettyUrl
yii2默认不支持类似 http://<domain>/site/error 的url格式，需要在config.php中启用 enablePrettyUrl 属性
[ //others ‘components‘ => [ ‘urlManager‘ => [ ‘enablePrettyUrl‘ => true, ], ], ];
2. 配置suffix 实现伪静态 *.html
需要在 config.php中配置 urlManager 即可
[ ‘components‘ => [ ‘urlManager‘ => [ ‘enablePrettyUrl‘ => true, ‘suffix‘ => ‘.html‘, ], ], ];
3. 同时支持 http://<domain>/site/error.html 以及 http://<domain>/site/error 的url格式
* 没有找到仅仅配置config便可以实现的方式，这里重写UrlManager。只重写了一句代码，仅贴部分展示代码
namespace common\yiiext\web;
use yii;
use yii\web\UrlManager as BaseUrlManager;
class UrlManager extends BaseUrlManager
{
public function parseRequest($request)
{
if ($this->enablePrettyUrl) {
//other code ...
if ($suffix !== ‘‘ && $pathInfo !== ‘‘) {
$n = strlen($this->suffix);
if (substr_compare($pathInfo, $this->suffix, -$n, $n) === 0) {
$pathInfo = substr($pathInfo, 0, -$n);
if ($pathInfo === ‘‘) {
// suffix alone is not allowed
return false;
}
} else {
// 就这一句区别用父类
// suffix doesn‘t match
return [$pathInfo, []];
}
}
//other code ..
}
}
* 然后再次配置config.php
[ ‘components‘ => [ ‘urlManager‘ => [ ‘class‘ => ‘common\yiiext\web\UrlManager‘, ‘enablePrettyUrl‘ => true, ‘suffix‘ => ‘.html‘, ], ], ];
