在您的情况下，您需要实现自定义SOAP API端点。幸运的是，您可能会大量重用可下载产品API实现。
如果创建下面列出的所有文件，那么将提供新的SOAP V2 API：catalogProductAttachLinkList。要启用添加/删除方法，只需将它们从app / code / core / Mage / Downloadable / Model / Link / Api.php移植到app / code / community / Intellimage / Attachs / Model / Link / Api.php即可。
要测试新的API，请运行以下任一操作：
<?php
/* SOAP V2 Style */
$client = new SoapClient('http://simple-magento-vagrant.dev/index.php/api/v2_soap/?wsdl');
$sessionId = $client->login('apiUser', 'apiKey');
$productId = 1;
$result = $client->catalogProductAttachLinkList($sessionId, $productId);
print_r($result);
/* SOAP V1 style. If you want to use this style, you may skip creation of custom wsdl.xml and Api/V2.php files proposed below. Adding api.xml and Api.php will be enough */
$client = new SoapClient('http://simple-magento-vagrant.dev/index.php/api/soap/?wsdl');
$sessionId = $client->login('apiUser', 'apiKey');
$productId = 1;
$result = $client->call($sessionId, 'attach_link.list', [$productId]);
print_r($result);
要添加到模块的文件：
app / code / community / Intellimage / Attachs / etc / api.xml
<?xml version="1.0"?>
<config>
<api>
<resources>
<catalog_product_attach_link translate="title" module="intellimage_attachs">
<model>attachs/link_api</model>
<title>Category API</title>
<acl>downloadable/link</acl>
<methods>
<list translate="title" module="intellimage_attachs">
<title>Retrieve links and samples list from attach product</title>
<method>items</method>
<acl>downloadable/link/list</acl>
</list>
</methods>
</catalog_product_attach_link>
</resources>
<resources_alias>
<attach_link>catalog_product_attach_link</attach_link>
</resources_alias>
<v2>
<resources_function_prefix>
<attach_link>catalogProductAttachLink</attach_link>
</resources_function_prefix>
</v2>
</api>
</config>
app / code / community / Intellimage / Attachs / etc / wsdl.xml
（请注意，如果需要与SOAP V2 WS-I兼容，则应创建wsi.xml）
<?xml version="1.0"?>
<config>
<api>
<resources>
<catalog_product_attach_link translate="title" module="intellimage_attachs">
<model>attachs/link_api</model>
<title>Category API</title>
<acl>downloadable/link</acl>
<methods>
<list translate="title" module="intellimage_attachs">
<title>Retrieve links and samples list from attach product</title>
<method>items</method>
<acl>downloadable/link/list</acl>
</list>
</methods>
</catalog_product_attach_link>
</resources>
<resources_alias>
