如何在 Autodesk Forge Design Automation SDK 中上传 Zip 文件并创建 AppBundle？

Question

我正在尝试将 zip 文件上传到 Autodesk Forge 的对象存储服务 (OSS)，然后使用它为 Design Automation 创建 AppBundle。当我成功上传文件并创建 AppBundle 时，链接到 AppBundle 的包 URL 在访问时总是给出 NoSuchKey 错误。

这是我的代码的相关部分：

var auth = new TwoLeggedApi();

dynamic tokenResponse = await auth.AuthenticateAsync(
    ClientId,
    ClientSecret,
    oAuthConstants.CLIENT_CREDENTIALS,
    [Scope.DataRead, Scope.DataWrite]
);

var objectsApi = new ObjectsApi { Configuration = { AccessToken = tokenResponse.access_token; } };

using var fileStream = new FileStream(zipFilePath, FileMode.Open, FileAccess.Read);

dynamic response = await objectsApi.UploadObjectAsync(
    bucketKey,
    objectKey,
    (int)fileStream.Length,
    fileStream,
    "application/zip"
);

string ossObjectUrl = $"https://developer.api.autodesk.com/oss/v2/buckets/{bucketKey}/objects/{objectKey}";

string fullyQualifiedId = $"{_account}.{bundleId}";
var newVersion = new AppBundle
{
    Id = fullyQualifiedId,
    Engine = $"Autodesk.Revit+{yearVersion}",
    Package = ossObjectUrl,
    Description = $"App bundle for Revit {yearVersion}",
};

AppBundle bundle = await _daClient.CreateAppBundleAsync(newVersion);
// package URL is valid
// after creating an alias and fetching the AppBundle again, the package url is invalid

AppBundle 创建成功，但是当我设置别名并尝试访问包 URL 时，出现错误：

<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
</Error>

您无法将 OSS URL 传递给 AppBundle 类中的 Package 属性。此属性需要位于本地磁盘上的包 zip 文件的路径。

var newVersion = new AppBundle
{
    Id = fullyQualifiedId,
    Engine = $"Autodesk.Revit+{yearVersion}",
    Package = @"D:\Temp\package.zip", // Must be a local disk path
    Description = $"App bundle for Revit {yearVersion}",
};

管理 AppBundle 的步骤：

1. 注册AppBundle:
   使用设计自动化 API (

   https://developer.api.autodesk.com/da/us-east/v3/appbundles

   ) 创建新的 AppBundle 并获取上传详细信息。
2. 上传AppBundle：
   将 AppBundle zip 文件上传到提供的签名 AWS URL。确保包含所有必需的表单数据。
3. 创建别名:
   为 AppBundle 分配别名（例如

   test

   ）以方便版本管理。

示例代码

private async Task<string> SetupAppBundleAsync()
{
    // Log the start of the AppBundle setup process
    Console.WriteLine("Setting up AppBundle...");

    // Construct the fully qualified AppBundle name
    var myApp = $"{_config.Owner}.{_config.BundleName}+{_config.Label}";

    // Check if the AppBundle already exists
    var appResponse = await _designAutomationClient.AppBundlesApi.GetAppBundleAsync(myApp, throwOnError: false);

    // Define the new AppBundle details
    var app = new AppBundle
    {
        Engine = _config.TargetEngine,
        Id = _config.BundleName
    };

    // Validate that the package path is not null
    var package = _config.BundlePath ?? throw new NullReferenceException("BundlePath cannot be null.");

    if (appResponse.HttpResponse.StatusCode == HttpStatusCode.NotFound)
    {
        // If the AppBundle doesn't exist, create it
        Console.WriteLine($"\tCreating AppBundle {myApp}...");
        await _designAutomationClient.CreateAppBundleAsync(app, _config.Label, package);
        return myApp;
    }

    // Ensure the response is successful if the AppBundle exists
    await appResponse.HttpResponse.EnsureSuccessStatusCodeAsync();
    Console.WriteLine("\tFound existing AppBundle...");

    // Check if the existing package matches the new one
    if (!await EqualsAsync(package, appResponse.Content.Package))
    {
        // If the packages differ, update the AppBundle
        Console.WriteLine($"\tUpdating AppBundle {myApp}...");
        await _designAutomationClient.UpdateAppBundleAsync(app, _config.Label, package);
    }

    // Return the name of the AppBundle
    return myApp;
}
