如何将图像作为asp.net web api中的参数上传到亚马逊S3

public IHttpActionResult UploadImage(HttpPostedFileBase image)
{
    // 处理图像上传逻辑
    // ...
}

public IHttpActionResult UploadImage(HttpPostedFileBase image)
{
    // 亚马逊S3凭证
    string accessKey = "YOUR_ACCESS_KEY";
    string secretKey = "YOUR_SECRET_KEY";
    string bucketName = "YOUR_BUCKET_NAME";

    // 创建AmazonS3Client对象
    AmazonS3Client s3Client = new AmazonS3Client(accessKey, secretKey, Amazon.RegionEndpoint.USWest2);

    // 生成唯一的文件名
    string fileName = Guid.NewGuid().ToString() + Path.GetExtension(image.FileName);

    // 上传图像文件到S3存储桶
    using (var fileTransferUtility = new TransferUtility(s3Client))
    {
        fileTransferUtility.Upload(image.InputStream, bucketName, fileName);
    }

    // 返回图像文件的URL
    string imageUrl = $"https://{bucketName}.s3.amazonaws.com/{fileName}";

    return Ok(imageUrl);
}
