yii2 的 restful 接口的默认  是帮写了很多的方法

下面我们需要书写自己的接口方法，譬如查找name是xxxx的条目

'urlManager' => [
'class' => 'yii\web\UrlManager',
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
'rules' => [
'' => 'cms/index',
['class' => 'yii\rest\UrlRule', 'controller' => 'customer/api','pluralize' => false,
],
#  定义方法: public function actionSearch($name);   <name> 就是search方法传入的参数
'POST customer/api/search/<name>' => 'customer/api/search',
//'POST customer' => 'customer/index/create',
],
],

也就是添加：

'POST customer/api/search/<name>' => 'customer/api/search',

name代表的是参数

2.我们需要返回的是json格式：

<?php
namespace myapp\frontend\code\ECM\Customer\controllers;
use yii\web\Response;
use Yii;
use yii\rest\ActiveController;
use myapp\frontend\code\ECM\User\models\Product;
class ApiController extends ActiveController
{public $modelClass = 'myapp\frontend\code\ECM\User\models\Product';
public function behaviors()
{
$behaviors = parent::behaviors();
#定义返回格式是：JSON
$behaviors['contentNegotiator']['formats']['text/html'] = Response::FORMAT_JSON;
return $behaviors;
}
public function actionSearch($name){
$one = Product::findOne(['name'=>$name]);
return $one;
}
}

访问：

curl -i -H "Accept:application/json" -H "Content-Type:application/json" -XPOST "http://10.10.10.252:800/customer/api/search/xxxx"

结果：

HTTP/1.1 200 OK
