AEM资产API:根据需要创建中间目录

Question

我正在使用AEM 6.3。我正在使用资产 API 使用curl命令上传资产。这就是我的做法：

curl -i 'http://localhost:4502/api/assets/newFolder' -H "Content-Type: application/json" -d '{"class":"assetFolder","properties":{"title":"New folder"}}' -u admin:admin

我的用例需要创建中间目录(如果它们不存在(。像这样：

curl -i 'http://localhost:4502/api/assets/intermediate1/intermediate2/newFolder' -H "Content-Type: application/json" -d '{"class":"assetFolder","properties":{"title":"New folder"}}' -u admin:admin

在上面的示例中，中间 1 和中间 2 都不存在。卷曲不起作用，AEM返回：

HTTP/1.1 500 Server Error

500 错误很奇怪。从日志中我可以看到：

21.08.2019 11:13:35.512 *ERROR* [0:0:0:0:0:0:0:1 [1566396815508] POST /api/assets/intermediate1/intermediate2/newFolder HTTP/1.1] com.adobe.granite.rest.impl.servlet.PostRequest Exception during request processing.
java.lang.NullPointerException: null
at com.adobe.granite.rest.assets.impl.AssetResourceProvider.getDataPropertyKey(AssetResourceProvider.java:412)

如果中间文件夹不存在，也许AEM资产API不支持创建中间文件夹？也许 500 错误只是一个错误？

Answer 1

有 2 个选项可以使用资产 API。 您可以尝试以下任一方法：

以下示例显示了在资产层次结构中创建 2 个新文件夹。

选项1

curl -u admin:admin  http://localhost:4502/api/assets/we-retail/* -F"name=newfolder" -F"title=New Folder"

结果：

{"class":["core/response"],"properties":{"path":"/api/assets/we-retail/*","parentLocation":"/api/assets/we-retail.json","referer":"","isCreate":true,"changes":[{"argument":"/api/assets/we-retail/newfolder","type":"created"}],"location":"/api/assets/we-retail/newfolder.json","status.message":"Created","title":"Content created /api/assets/we-retail/*","status.code":201}}

选项 2

curl -u admin:admin  http://localhost:4502/api/assets/we-retail/newfolder/images -H"Content-Type: application/json" -d "{"class":"assetFolder","properties":{"title":"Images"}}"

结果

{"class":["core/response"],"properties":{"path":"/api/assets/we-retail/newfolder/images","parentLocation":"/api/assets/we-retail/newfolder.json","referer":"","isCreate":true,"changes":[{"argument":"/api/assets/we-retail/newfolder/images","type":"created"}],"location":"/api/assets/we-retail/newfolder/images.json","status.message":"Created","title":"Content created /api/assets/we-retail/newfolder/images","status.code":201}}

默认情况下，命令提示符下无法识别单引号。将其更改为双引号应该有效

创建文件夹的其他方法，强制主要类型为整个层次结构的sling：folder

curl -u admin:admin -Fjcr:primaryType=sling:Folder localhost:4502/content/dam/mFolder/aFolder
