Cakephp我如何创建一个带有维护路径的accept id和cat id的路由

Question

我有一个API前缀路由，我有一台控制器，我试图在那里获取产品，然后是按id获取产品，再是按类别id获取产品。

所以，我创建了一个前缀路由

$routes->scope('/api', function (RouteBuilder $routes) {
$routes->setExtensions(['json']);
$routes->resources('Shops',[
'prefix' => 'Api',
'path' => 'shops',
'map' => [
'getProducts' => [
'action' => 'getProducts',
'method' => 'GET',
'path' => '/products'
],
'getProductById' => [
'action' => 'getProducts',
'method' => 'GET',
'path' => '/products/{id}',
],
'getProductBySubcatId' => [
'action' => 'getProducts',
'method' => 'GET',
'path' => '/products/cat/{cat_id}',
'subcat_id' => [0-10]
],
]
]);
});

实际上，在行动中，我正在尝试进行

public function getProducts($id = null, $cat_id = null)
{   
if($id)
-----
else if($cat_id)
----
}

我需要像一样获取数据

http://localhost:8000/api/shops/products/cat/1.json

出席者对于以下URL

http://localhost:8000/api/shops/products/1.json

我让参数通过

protected params => [
'id' => '1',
'pass' => [
(int) 0 => '1',
],

但对于猫来说，我没有通过http://localhost:8000/api/shops/products/cat/1.json

protected params => [
'catId' => '1',
'pass' => [ ],

此外，我可以发送字符串作为猫id 的参数

protected params => [
'catId' => 'A',
'pass' => [ ],

如何在通行证中添加catId？此外，我如何添加catId始终为int的验证？

Answer 1

您可以使用connectOptions解决它

map [
// your map 
],
'connectOptions' => [
'catId' => '[0-9]+',
'pass' => ['id','catId'],
],

有关详细信息，请查看RouteBuilder.php类

Answer 2

将尝试在方法中使用排列运算符：

public function getProducts(...$params)
{   
//try to understand spread operator
debug($params);
if (count($params) == 2 && !is_number($params[0]) && is_number($params[1]) {
$id = strval($params[0]);
$cat_id = intval($params[1]);
}
if (count($params) == 1 && is_number($params[0]) {
$id = null;
$cat_id = intval($params[0]);
}
// ... implement your code     
}
