Question

我想将文件上传到Azure Iot Hub Blob。我找到了API：

IoTHubClient_LL_UploadToBlob

但是当我仅这样做时，它将报告一个错误：

有我的代码。 data是iOS数据结构，可以是图像或音频。

let source = UnsafePointer<UInt8>((data as NSData).bytes.assumingMemoryBound(to: UInt8.self))

if (IoTHubClient_LL_UploadToBlob(iotHubClientHandle, "iOS/\(filename)", source, data.count)) != IOTHUB_CLIENT_OK {
    print("failed to upload \(filename)")
} else {
    print("success to upload \(filename)")
}

我明白了：

我应该做其他事情吗？也许发送POST请求以获取SAS令牌？

请举个例子。
