Autodesk Forge数据管理API下载项目

我试图通过Autodesk Forge Data Management API从A360下载文件。 documentation指出为'Items'或'Versions'返回的JSON应该有一个名为'included.relationships.storage.meta.link.href'的部分。Autodesk Forge数据管理API下载项目

第5步：查找某一项目

如果你只想要最新版本的版本，你可以简单地获取链接从上一步骤的响应体。在上面的例子中，我们可以看到在 included.relationships.storage.meta.link.href属性（https://developer.api.autodesk.com/oss/v2/buckets/wip.dm.prod/objects/977d69b1-43e7-40fa-8ece-6ec4602892f3.rvt）可用于下载的项府Design.rvt的存储位置。

但是，返回的JSON似乎有此部分丢失。

即GET项目/：PROJECT_ID /项目/：ITEM_ID

上传了一个新文件后，这似乎有可用的存储数据。所有现有文件在数月内都没有更新，因此没有存储数据。这可能是遗留数据的问题吗？ – BassetMan

这是一个传统的迁移，我会仔细检查你的日期。 –

是的，你是正确的，不幸的是，上传到A360的旧文件不会通过API暴露“数据”字段。开发团队正在努力在将来添加此功能，但我无法告诉您何时可用，对于这个坏消息抱歉。

你为了下载一个项目所需要的是首先要知道你想要的版本，然后从

version.relationships.storage.data.id

这里是我的客户端代码获得objectKey和bucketKey：

///////////////////////////////////////////////////////////////// 
// Download object from version 
// 
///////////////////////////////////////////////////////////////// 
download (version) { 

    // retrieves bucketKey/objectKey from storage Id 

    var objectId = this.parseObjectId(
    version.relationships.storage.data.id) 

    var uri = `${this.apiUrl}/buckets/` + 
    `${objectId.bucketKey}/objects/${objectId.objectKey}` 

    var link = document.createElement('a') 

    link.download = version.attributes.displayName 
    link.href = uri 
    link.click() 
}

和服务器端（node.js）

////////////////////////////////////////////////////////////////////// 
// GET /buckets/:bucketKey/objects/:objectKey 
// Download an item version based on { bucketKey, objectKey } 
// 
///////////////////////////////////////////////////////////////////// 
router.get('/buckets/:bucketKey/objects/:objectKey', async (req, res) => { 

    try { 

    var bucketKey = req.params.bucketKey 

    var objectKey = req.params.objectKey 

    var forgeSvc = ServiceManager.getService(
     'ForgeSvc') 

    var ossSvc = ServiceManager.getService(
     'OssSvc') 

    var token = await forgeSvc.get3LeggedTokenMaster(
     req.session) 

    var object = await ossSvc.getObject(
     token.access_token, 
     bucketKey, objectKey) 

    res.end(object) 

    } catch(ex) { 

    res.status(ex.status || 500) 
    res.json(ex) 
    } 
})

希望可以帮到

感谢Philippe，我设法下载了一个没有问题的新上传的文件。但最初只是试图下载现有的内容，没有喜悦。 – BassetMan

是的，不幸的是我不能告诉你什么时候可以这样做......您可以通过以下方式在我们的新博客上继续关注最新的Forge更新：https：//forge.autodesk.com/blog –
