问题 I am saving zip files to an AWS S3 bucket. I am now trying to create a C# .NET API that will allow me to download a specified key from the bucket and save it to a HttpResponseMessage in the Content key. I've referred to the following question to set up my response for zip files: How to send a zip file from Web API 2 HttpGet I have modified the code in the previous question so that it instead reads from a TransferUtility stream.

问题 So I've tried looking through previous answers on here and nothing seems to be working. I'm using Dropzone, which appears to make an OPTIONS request to get all the allowed CORS related information, but it doesn't seem to be returning properly So from looking in the Chrome dev tools, I have the following Request Headers Host: mybucket.s3.amazonaws.com Connection: keep-alive Pragma: no-cache Cache-Control: no-cache Access-Control-Request-Method: POST Origin: http://localhost:9010 User-Agent:
