Question

versions API endpoint提到可以用来制作文档的副本。看来copyFrom参数是源文件urn的http编码值。示例中的Relationships.item.data.type.itemsid的值是什么？我是否需要首先创建一个空文件对象，然后在请求正文中提供该ID？

Answer 1

项目ID是您要从中复制文件的Data Management API的ID。您可以通过以下方式获取它：

您不必创建一个空文件对象，只需调用API：https://forge.autodesk.com/en/docs/data/v2/reference/http/projects-project_id-versions-POST/

例如，

这是一个存储在文档中的RVT模型，其项目数据如下：

{
   "type": "items",
   "id": "urn:adsk.wipprod:dm.lineage:rH_L4XJsTmeiYA4ixCVNAA",   //!<<< Item id
   "attributes": {
       "displayName": "rac_basic_sample_project.rvt",
       "createTime": "2019-09-25T06:56:26.0000000Z",
       //...
       "lastModifiedTime": "2019-09-25T06:56:27.0000000Z",
       //...
       "hidden": false,
       "reserved": false,
       "extension": {
           "type": "items:autodesk.bim360:File",
           "version": "1.0",
           "schema": {
               "href": "https://developer.api.autodesk.com/schema/v1/versions/items:autodesk.bim360:File-1.0"
           },
           "data": {
               "sourceFileName": "rac_basic_sample_project.rvt"
           }
       }
   },


   //...
}

然后调用https://developer.api.autodesk.com/data/v1/projects/ {PROJECT_ID} /items/urn:adsk.wipprod:dm.lineage:rH_L4XJsTmeiYA4ixCVNAA/versions以获取其版本记录：

{
   "type": "versions",
   "id": "urn:adsk.wipprod:fs.file:vf.rH_L4XJsTmeiYA4ixCVNAA?version=1",   //!<<< Version id
   "attributes": {
       "name": "rac_basic_sample_project.rvt",
       "displayName": "rac_basic_sample_project.rvt",
       "createTime": "2019-09-25T06:56:26.0000000Z",
       //...
       "lastModifiedTime": "2019-09-25T06:57:54.0000000Z",
       //...
       "versionNumber": 1,
       "storageSize": 17813504,
       "fileType": "rvt",
       "extension": {
           "type": "versions:autodesk.bim360:File",
           "version": "1.0",
           "schema": {
               "href": "https://developer.api.autodesk.com/schema/v1/versions/versions:autodesk.bim360:File-1.0"
           },
           "data": {
               "processState": "PROCESSING_COMPLETE",
               "extractionState": "SUCCESS",
               "splittingState": "NOT_SPLIT",
               "reviewState": "NOT_IN_REVIEW",
               "revisionDisplayLabel": "1",
               "sourceFileName": "rac_basic_sample_project.rvt"
           }
       }
   },

   //...  
}

现在，您要将此项的特定版本urn:adsk.wipprod:fs.file:vf.rH_L4XJsTmeiYA4ixCVNAA?version=1复制到另一个文件夹urn:adsk.wipprod:fs.folder:co.0xaYa2rVTJuFiz7rxLCOQQ。因此，API调用将如下所示：

注意。版本ID的网址安全格式为urn%3Aadsk.wipprod%3Afs.file%3Avf.rH_L4XJsTmeiYA4ixCVNAA%3Fversion%3D1

POST https://developer.api.autodesk.com/data/v1/projects/{PROJECT_ID}/items?copyFrom=urn%3Aadsk.wipprod%3Afs.file%3Avf.rH_L4XJsTmeiYA4ixCVNAA%3Fversion%3D1

{
   "jsonapi": {
     "version": "1.0"
   },
   "data": {
     "type": "items",
     "id": "urn:adsk.wipprod:dm.lineage:rH_L4XJsTmeiYA4ixCVNAA",
     "relationships": {
      "tip":{
            "data":{
               "type":"versions",
               "id":"1"
            }
         },
         "parent": {
             "data": {
                 "type": "folders",
                 "id": "urn:adsk.wipprod:fs.folder:co.0xaYa2rVTJuFiz7rxLCOQQ"  //!<<< The folder we want to put this file
             }
         }
     }
   },
   "included":[
      {
         "type":"versions",
            "id":"1",
            "attributes":{
               "name":"rac_basic_sample_project.rvt"   //!<<< Version name
            }
      }
   ]
}

希望有帮助！
