我的商店有magento2，我想用REST API获取所有可配置/简单的产品及其子（变体）产品。我可以在单个REST API调用中获取所有产品，但它不能为我提供可配置产品的孩子。
我需要可配置的产品，如下所示：
{
"id":1,
"parent_id":1,
"name":"myProduct",
"is_active":true,
.................
"children_data":[
{
"id":1,
"parent_id":1,
"name":"myProduct",
"is_active":true,
.................
},
{
"id":1,
"parent_id":1,
"name":"myProduct",
"is_active":true,
.................
}
]
}

您需要使用以下REST API来获取子数据
GET / V1 / configurable-products / {sku} / children
回应：
[
{
"sku": "MH01-XS-Black",
"name": "Chaz Kangeroo Hoodie-XS-Black",
"attribute_set_id": 9,
"price": 52,
"status": 1,
"type_id": "simple",
"created_at": "2015-11-20 08:12:24",
"updated_at": "2015-11-20 08:12:24",
"weight": 1,
"extension_attributes": [],
"product_links": [],
"tier_prices": [],
"custom_attributes": [
{
"attribute_code": "required_options",
"value": "0"
},
{
"attribute_code": "has_options",
"value": "0"
},
{
"attribute_code": "tax_class_id",
"value": "2"
},
{
"attribute_code": "image",
"value": "/m/h/mh01-black_main.jpg"
},
{
"attribute_code": "category_ids",
"value": [
"2",
"15",
"36"
]
},
{
"attribute_code": "size",
"value": "167"
},
{
"attribute_code": "color",
"value": "49"
},
{
"attribute_code": "small_image",
"value": "/m/h/mh01-black_main.jpg"
},
{
"attribute_code": "thumbnail",
"value": "/m/h/mh01-black_main.jpg"
},
{
"attribute_code": "url_key",
"value": "chaz-kangeroo-hoodie-xs-black"
},
{
"attribute_code": "msrp_display_actual_price_type",
"value": "0"
}
]
},
...
]
如果您需要所有可配置选项并调用以下API
GET / V1 / configurable-products / {sku} / options / all
回应：
[
{
"id": 3,
"attribute_id": "90",
"label": "Color",
"position": 0,
"values": [
{
"value_index": 49
},
{
"value_index": 52
},
{
"value_index": 56
}
],
"product_id": 67
},
{
"id": 2,
"attribute_id": "137",
"label": "Size",
"position": 0,
"values": [
{
"value_index": 167
},
{
"value_index": 168
},
{
"value_index": 169
},
{
"value_index": 170
},
{
"value_index": 171
}
],
"product_id": 67
}
]

Magento允许开发人员在配置文件webapi.xml中定义Web API资源及其权限。以下是有关公开services as Web APIs的详细信息。
在进行Web API调用之前，您必须验证您的身份并拥有访问API资源所需的权限（授权）。身份验证允许Magento识别呼叫者的用户类型。根据用户（管理员，集成，客户或访客）访问权限，确定API调用的资源可访问性。
每个Magento Web API调用都包含以下元素的组合：
2.1 HTTP动词
GET。请求传输目标的当前表示
资源。如果省略动词，则GET是默认值。 PUT。要求
用目标资源创建或替换目标资源的状态
由请求消息中包含的表示定义的状态
有效载荷。 POST。请求原始服务器接受
请求中包含的表示作为要处理的数据
目标资源。 DELETE。请求原始服务器删除
目标资源。2.2 ConfigurableProduct的端点
GET /V1/configurable-products/:sku/children
DELETE /V1/configurable-products/:sku/children/:childSku
PUT /V1/configurable-products/variation
POST /V1/configurable-products/:sku/child
GET /V1/configurable-products/:sku/options/:id
GET /V1/configurable-products/:sku/options/all
POST /V1/configurable-products/:sku/options
PUT /V1/configurable-products/:sku/options/:id
DELETE /V1/configurable-products/:sku/options/:id
2.3 HTTP标头
要在cURL命令中指定HTTP标头，请使用
-H或--header选项。
在Web API调用中指定以下一个或多个HTTP标头：
.---------------.-----------------------------------.
| HTTP header | Syntax |
|---------------|-----------------------------------|
| Authorization | Authorization: Bearer <TOKEN> |
| Accept | Accept: application/<FORMAT> |
| Content-Type | Content-Type:application/<FORMAT> |
'---------------'-----------------------------------'
其中<TOKEN>是Magento令牌服务返回的身份验证令牌。请参阅身份验证。
2.4呼叫有效负载
呼叫有效负载是您随请求提供的输入参数和属性的集合。 API操作具有必需和可选输入。
您可以在URI中指定输入参数。
您可以在JSON或XML格式的请求正文中指定输入属性。
2.5构建请求
准备要传递给请求对象的Authorization，Accept和Content-Type标头。使用Magento令牌服务返回的授权令牌。
$token = 'token';
$httpHeaders = new \Zend\Http\Headers();
$httpHeaders->addHeaders([
'Authorization' => 'Bearer ' . $token,
'Accept' => 'application/json',
'Content-Type' => 'application/json'
]);
打开Magento/ConfigurableProduct/etc/webapi.xml配置文件，然后从Magento\ConfigurableProduct\Api\LinkManagementInterface界面找到getChildren方法。
将标头，URI和方法设置为请求对象。
$request = new \Zend\Http\Request();
$request->setHeaders($httpHeaders);
$request->setUri('http://yourdomain.com/rest/V1/configurable-products/:sku/children');
$request->setMethod(\Zend\Http\Request::METHOD_GET);
$params = new \Zend\Stdlib\Parameters([
'sku' => 'sku-needed-for-example'
]);
$request->setQuery($params);
准备HTTP Curl客户端对象并将请求对象传递给Client::send()方法。
$client = new \Zend\Http\Client();
$options = [
'adapter' => 'Zend\Http\Client\Adapter\Curl',
'curloptions' => [CURLOPT_FOLLOWLOCATION => true],
'maxredirects' => 0,
'timeout' => 30
];
$client->setOptions($options);
$response = $client->send($request);
此请求以JSON格式返回所有子项的列表。您还可以通过更改请求的XML标头来指定Accept格式。
cURL是一个命令行工具，可让您从命令行或shell脚本发送和接收HTTP请求和响应。它适用于Linux发行版，Mac OS X和Windows。
要使用cURL运行REST Web API调用，请使用cURL命令语法构造cURL命令。
要在调用中创建端点，请附加在步骤2.5中构造的REST URI构造对此URL的请求：
https://<MAGENTO_HOST_OR_IP>/<MAGENTO_BASE_INSTALL_DIR>/rest/
有关cURL命令选项的完整列表，请参阅curl.1 the man page。
每个Web API调用都返回HTTP状态代码和响应有效负载。当出现错误时，响应主体也会返回错误消息。
HTTP状态代码
每个Web API调用都会返回一个反映请求结果的HTTP状态代码：
.===========.=================.=================================================.
| HTTP code | Meaning | Description |
|===========|=================|=================================================|
| 200 | Success | M2 return HTTP 200 to the caller upon success. |
|-----------|-----------------|-------------------------------------------------|
| | | If service implementation throws either |
| | | `Magento_Service_Exception` or its derivative, |
| | | the framework returns a HTTP 400 with a error |
| | | response including the service-specific error |
| 400 | Bad Request | code and message. This error code could |
| | | indicate a problem such as a missing required |
| | | parameter or the supplied data didn't pass |
| | | validation. |
|-----------|-----------------|-------------------------------------------------|
| 401 | Unauthorized | The caller was not authorized to perform the |
| | | request. For example, the request included an |
| | | invalid token or a user with customer |
| | | permissions attempted to access an object that |
| | | requires administrator permissions. |
|-----------|-----------------|-------------------------------------------------|
| 403 | Forbidden | Access is not allowed for reasons that are not |
| | | covered by error code 401. |
|-----------|-----------------|-------------------------------------------------|
| 404 | Not found | The specified REST endpoint does not exist. The |
| | | caller can try again. |
|-----------|-----------------|-------------------------------------------------|
| 405 | Not allowed | A request was made of a resource using a method |
| | | that is not supported by that resource. For |
| | | example, using GET on a form which requires data|
| | | to be presented via POST, or using PUT on a |
| | | read-only resource. |
|-----------|-----------------|-------------------------------------------------|
| 406 | Not acceptable | The requested resource is only capable of |
| | | generating content that is not acceptable |
| | | according to the Accept headers sent in the |
| | | request. |
|-----------|-----------------|-------------------------------------------------|
| 500 | System Errors | If service implementation throws any other |
| | | exception like network errors, database |
| | | communication, framework returns HTTP 500. |
'==========='================='================================================='
响应有效负载
POST，PUT和GET Web API调用返回响应有效负载。此有效内容是JSON或XML格式的响应正文。请求中的Accept：application / header确定响应主体的格式，其中FORMAT是json或xml。
成功的DELETE调用返回true。不成功的DELETE调用返回与其他调用类似的有效负载。
错误格式
发生错误时，响应正文包含错误代码，错误消息和可选参数。
.------------.---------------------------------------------------------------.
| Part | Description |
|------------|---------------------------------------------------------------|
| code | The status code representing the error. |

| message | The message explaining the error. |
|------------|---------------------------------------------------------------|
| parameters | Optional. An array of attributes used to generate a different |
| | and/or localized error message for the client. |
