【问题描述】：

我需要使用 Magento 2 rest api 按名称查找类别。我使用/all/V1/categories 和过滤器，但我无法让它工作。代码如下：

$url = "https://*******/index.php/rest";
$token_url= $url."/V1/integration/admin/token";
  
$ch = curl_init();
$data = array("username" => USERNAME, "password" => PASSWORD);
$data_string = json_encode($data);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $token_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json'
    ));
$token = curl_exec($ch);
$adminToken=  json_decode($token);
$headers = array('Content-Type:application/json','Authorization:Bearer '.$adminToken);

$ch = curl_init();

$apiUrl = $url."/all/V1/categories";

$data = [
    "searchCriteria" => [
        "filterGroups" => [
            "filters" => [
                "fieldName" => "category",
                "value" => 'CATEGORY NAME',
                "condition_type" => 'eq'
            ]
        ]
    ],
];

$data_string = json_encode($data);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);

$response = json_decode($response, TRUE);
curl_close($ch);

这是启动代码后出现的错误：

array:3 [▼ "message" => ""%fieldName" is required."  "parameters" => array:1 [▼ "fieldName" => "category" ]

【解决方案1】：

您可以通过将搜索条件添加到端点rest/all/V1/categories/list 来使用 Magento 2 rest api 按名称获取类别。对 api 的请求应如下所示：

https://website.com/rest/all/V1/categories/list?searchCriteria%5BfilterGroups%5D%5B0%5D%5Bfilters%5D%5B0%5D%5Bfield%5D=name&searchCriteria%5BfilterGroups%5D%5B0%5D%5Bfilters%5D%5B0%5D%5Bcondition_type%5D=eq&searchCriteria%5BfilterGroups%5D%5B0%5D%5Bfilters%5D%5B0%5D%5Bvalue%5D=category_name

将website.com 替换为您网站的网址，将category_name 替换为类别的搜索词。

如果搜索字符串也应该匹配部分类别名称，您可以使用like 而不是eq。
