露天：从CMIS获取数据响应

Question

我的目的是使用PHP脚本，来实现这一点，我在下面终端执行卷曲声明基本上列出露天场地中的文件夹，

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

，我也得到了响应，下面，

我如何获取PHP中的子数据？即基本上是标题'documentLibrary'，它是objectId。

Answer 1

，而不是分析的原子在自己的饲料中，可以使用下面的PHP库：http://chemistry.apache.org/php/phpclient.html

Answer 2

如果你的使用情况很简单，只要你所描述的东西，你可以使用XPath在PHP查询你正在处理的数据。

下面是XPath查询，你可以使用：

选择“标题”元素（我建议选择propertyString CMIS：名称，而不是 - 虽然CMIS规范指定CMIS：名称必须在原子设置：标题元素，我发现那里的仓库不设置标题元素，因为它在CMIS规范中定义的情况下）

//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与更多复杂用例进行交互，请查看Apache Chemistry CMIS PHP Client（http://chemistry.apache.org/php/phpclient.html）以获取健壮的客户端库，并查看客户端库是否适合您的需求。

编辑 - 一个简单的例子，把它放在一起......

// 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"
