Yii2 之 UrlManager 实践 (一)

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‘,
		],
	],
];
