使用AWS c ++界面将文件上传到s3时Content-Type标记不正确

Question

I'm trying to upload a file to S3 using the AWS C++ SDK. The file transfers just fine but the content type is "binary/octet-stream" instead of "text/html". When I look at the file in the S3 console. There is a "x-amz-meta-content-type" metadata record of type "text/html". How can I set the actual content type of the file I want to upload?

int main (int, char**)
{
   Aws::SDKOptions options;
   Aws::InitAPI (options);
   client = new Aws::S3::S3Client;

   Aws::S3::Model::PutObjectRequest request;
   request.SetBucket ("mywebsite.notreal.net");
   request.SetKey ("index.html");
   request.SetACL (Aws::S3::Model::ObjectCannedACL::public_read);
   request.SetContentEncoding ("UTF-8");
   request.AddMetadata ("Content-Type", "text/html");

   auto inputData = Aws::MakeShared<Aws::FStream> ("PutObjectInputStream", "index.html", std::ios_base::in | std::ios_base::ate);
   request.SetContentLength (inputData-> tellg ());
   request.SetBody (inputData);

   auto result = client-> PutObject (request);
   return result.IsSuccess () ? 0 : 1;
}

The Content-Type needs to be set as an HTTP header in the actual PUT request.

Looking at the documentation , there's a SetContentType method you can use.
