Question

我的意图是基本上使用php脚本列出Alfresco网站中的文件夹，为了实现这一点，我在终端执行curl语句，如下所示，

curl -u admin:admin123 http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/02f9530f-a1b1-4d6d-b479-b5355692b8e2/children

我得到的答案如下，

如何在php中获取子数据？即基本上是标题'documentLibrary'和它的objectId。

Answer 1

您可以使用以下PHP库，而不是自己解析Atom提要：http://chemistry.apache.org/php/phpclient.html

Answer 2

如果您的用例与您所描述的一样简单，您可以在PHP中使用XPath来查询您所追踪的数据。

以下是您可以使用的XPath查询：

选择“Title”元素（我建议选择propertyString cmis：name - 尽管CMIS规范指定必须在atom：title元素中设置cmis：name，我发现了存储库执行的情况不设置CMIS规范中定义的title元素

//cmis:propertyString[contains(@propertyDefinitionId, 'cmis:name')][1]/cmis:value/text()

选择cmis：objectId

//cmis:propertyId[contains(@propertyDefinitionId, 'cmis:objectId')][1]/cmis:value[1]/text()

如果您通过CMIS与Alfresco进行更复杂的用例交互，请查看Apache Chemistry CMIS PHP客户端（http://chemistry.apache.org/php/phpclient.html）以获取强大的客户端库，并查看客户端库是否符合您的需求。

编辑 - 将所有内容组合在一起的简单示例......

// Load the XML String into a SimpleXMLElement
$sxe = new SimpleXMLElement($xmlResponse);

// Optional but good practice - register namespaces
$sxe->registerXPathNamespace('cmis', 'http://docs.oasis-open.org/ns/cmis/core/200908/');

// Execute XPath Query
$result = $sxe->xpath("//cmis:propertyString[contains(@propertyDefinitionId, 'cmis:name')][1]/cmis:value/text()");

// Do something with the result.
echo $result[0]  // For XPath above this will print: "documentLibrary"
