我正在学习Forge平台。我目前正在使用由Kean Walmsley编写的示例（Jigsawify），因为它最准确地描述了我的目标。我遇到了使我的文件从Azure存储帐户下载到Forge的问题。我收到的错误是“ HTTP标头之一的值格式不正确”。我的问题是，在编写代码工作项时，有人如何解决HTTP协议问题？我可以在断点处查看工作项，但我不了解HTTP头中的缺陷，甚至在哪里都可以找到缺陷。我应该查看工作项的特定属性吗？如果我可以找到HTTP语句，则可以对其进行测试，但是我不在应该找到它的地方。
还是我完全脱离基地？
无论如何，这里是代码。这是基恩写的东西的修改版本：
static void SubmitWorkItem(Activity activity)
{
Console.WriteLine("Submitting workitem...");
CloudStorageAccount storageAccount =
CloudStorageAccount.Parse(Microsoft.Azure.CloudConfigurationManager.GetSetting("StorageConnectionString"));
StorageCredentials crd = storageAccount.Credentials;
CloudFileClient fileClient = storageAccount.CreateCloudFileClient();
CloudFileShare ShareRef = fileClient.GetShareReference("000scrub");
CloudFileDirectory rootDir = ShareRef.GetRootDirectoryReference();
CloudFile Fileshare = rootDir.GetFileReference("3359fort.dwg");
// Create a workitem
var wi = new WorkItem()
{
Id = "", // Must be set to empty
Arguments = new Arguments(),
ActivityId = activity.Id
};
if (Fileshare.Exists())
{
wi.Arguments.InputArguments.Add(new Argument()
{
Name = "HostDwg", // Must match the input parameter in activity
Resource = Fileshare.Uri.ToString(),
StorageProvider = StorageProvider.Generic // Generic HTTP download (vs A360)
});
}
wi.Arguments.OutputArguments.Add(new Argument()
{
Name = "Results", // Must match the output parameter in activity
StorageProvider = StorageProvider.Generic, // Generic HTTP upload (vs A360)
HttpVerb = HttpVerbType.POST, // Use HTTP POST when delivering result
Resource = null, // Use storage provided by AutoCAD.IO
ResourceKind = ResourceKind.ZipPackage // Upload as zip to output dir
});
container.AddToWorkItems(wi);
container.SaveChanges();
// Polling loop
do
{
Console.WriteLine("Sleeping for 2 sec...");
System.Threading.Thread.Sleep(2000);
container.LoadProperty(wi, "Status"); // HTTP request is made here
Console.WriteLine("WorkItem status: {0}", wi.Status);
}
while (
wi.Status == ExecutionStatus.Pending ||
wi.Status == ExecutionStatus.InProgress
);
// Re-query the service so that we can look at the details provided
// by the service
container.MergeOption =
Microsoft.OData.Client.MergeOption.OverwriteChanges;
wi = container.WorkItems.ByKey(wi.Id).GetValue();
// Resource property of the output argument "Results" will have
// the output url
var url =
wi.Arguments.OutputArguments.First(
a => a.Name == "Results"
).Resource;
if (url != null)
DownloadToDocs(url, "SGA.zip");
// Download the status report
url = wi.StatusDetails.Report;
if (url != null)
DownloadToDocs(url, "SGA-Report.txt");
}

Azure要求您在上传到预签名URL时指定x-ms-blob-type标头。参见https://github.com/Autodesk-Forge/design.automation-.net-input.output.sample/blob/master/Program.cs#L167

因此，我能够根据Albert迁移到Blob服务的建议，弄清楚如何从Azure将文件下载到Forge。这是代码：
static void SubmitWorkItem(Activity activity)
{
Console.WriteLine("Submitting workitem...");
CloudStorageAccount storageAccount =
CloudStorageAccount.Parse(Microsoft.Azure.CloudConfigurationManager.GetSetting("StorageConnectionString"));
CloudBlobClient BlobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer cloudBlobContainer = BlobClient.GetContainerReference("000scrub");
CloudBlockBlob blockBlob = cloudBlobContainer.GetBlockBlobReference("3359fort.dwg");
// Create a workitem
var wi = new WorkItem()
{
Id = "", // Must be set to empty
Arguments = new Arguments(),
ActivityId = activity.Id
};
if (blockBlob.Exists())
{
wi.Arguments.InputArguments.Add(new Argument()
{
Name = "HostDwg", // Must match the input parameter in activity
Resource = blockBlob.Uri.ToString(),
StorageProvider = StorageProvider.Generic, // Generic HTTP download (vs A360)
Headers = new System.Collections.ObjectModel.ObservableCollection<Header>()
{
new Header() { Name = "x-ms-blob-type", Value = "BlockBlob" } // This is required for Azure.
}
});
}
wi.Arguments.OutputArguments.Add(new Argument()
{
Name = "Results", // Must match the output parameter in activity
StorageProvider = StorageProvider.Generic, // Generic HTTP upload (vs A360)
HttpVerb = HttpVerbType.POST, // Use HTTP POST when delivering result
Resource = null, // Use storage provided by AutoCAD.IO
ResourceKind = ResourceKind.ZipPackage, // Upload as zip to output dir
});
container.AddToWorkItems(wi);
container.SaveChanges();
// Polling loop
do
{
Console.WriteLine("Sleeping for 2 sec...");
System.Threading.Thread.Sleep(2000);
container.LoadProperty(wi, "Status"); // HTTP request is made here
Console.WriteLine("WorkItem status: {0}", wi.Status);
}
while (
wi.Status == ExecutionStatus.Pending ||
wi.Status == ExecutionStatus.InProgress
);
// Re-query the service so that we can look at the details provided
// by the service
container.MergeOption =
Microsoft.OData.Client.MergeOption.OverwriteChanges;
wi = container.WorkItems.ByKey(wi.Id).GetValue();
// Resource property of the output argument "Results" will have
// the output url
var url =
wi.Arguments.OutputArguments.First(
a => a.Name == "Results"
).Resource;
if (url != null)
DownloadToDocs(url, "SGA.zip");
// Download the status report
url = wi.StatusDetails.Report;
if (url != null)
DownloadToDocs(url, "SGA-Report.txt");
}
未完成的是结果部分。 ZIP没有任何内容，但是，嘿，宝贝走对了吗？
谢谢阿尔伯特。 -查克（Chuck）
