yii2中定制restful api

一、apache配置
找到httpd.conf中的这两段内容：

 # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride none

将AllowOverride none</code> 改为 <code>AllowOverride all
#LoadModule rewrite_module libexec/apache2/mod_rewrite.so
将#去掉，打开rewrite模块

二、.htaccess文件
写入下面内容,并放入yii2根目录的web目录下：webroot/yii2/web(yii2是自己命名的项目名称，webroot的Apache根目录)

	Options +FollowSymLinks
	IndexIgnore /
	RewriteEngine on
	RewriteCond %{REQUEST_FILENAME} !-f
	RewriteCond %{REQUEST_FILENAME} !-d
	RewriteRule . index.php

三、config/web.php配置urlManager:

         .....
            'urlManager' => [
            'enablePrettyUrl' => true,
            'enableStrictParsing' => true,
            'showScriptName' => false,
            'rules' => [
                [
                    'class' => 'yii\rest\UrlRule',  'controller' => 'user' ,
                ],
            ],
        ] ,

访问路径：http://loacalhost/yii2/web/users</code>(yii自动讲名词变为复数形式，具体看文档，可取消)

四、controller继承ActiveController:

namespace app\controllers;
use yii\rest\ActiveController;
class CountryController extends ActiveController
{
    	public $modelClass = 'app\models\Country';
        ...
}

额外、不同modules下urlmanger配置:
假设生成了一个modules/v1 的模块，urlmanger配置如下

'urlManager' => [
            'enablePrettyUrl' => true,
            'enableStrictParsing' => true,
            'showScriptName' => false,
            'rules' => [
                [
                    'class' => 'yii\rest\UrlRule',  'controller' => ['v1/country'] ,
                ],
            ],
        ] ,
