Getting error regarding signing request

[RobQuatela]

Describe the bug

When using the SDK I am receiving this error below. I am not sure if this has something to do with using version 4 for signing. All I did was update the nuget packages to 4.x

The request signature we calculated does not match the signature you provided. Check your key and signing method.

Expected Behavior

I expected to make a PutObject request using the SDK

Current Behavior

I am receiving the error below on the same code before I updated the package

The request signature we calculated does not match the signature you provided. Check your key and signing method.

Reproduction Steps

`using var client = new AmazonS3Client("ACCESS_KEY", "SECRET_KEY",RegionEndpoint.USEast1);
try
{
var bytes = Convert.FromBase64String(base64Content);
using var stream = new MemoryStream(bytes);
var putRequest = new PutObjectRequest()
{
BucketName = "cdn.test.com/vcards",
Key = $"{fileName}.vcf",
InputStream = stream,
ContentType = "text/x-vcard"
};

            var response = await client.PutObjectAsync(putRequest);
            return $"https://cdn.test.com/vcards/{fileName}.vcf";
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }`

No, this is not a regression in V4. Newer versions of the S3 package (after 3.7.100) do not allow the bucket name to contain the key prefix (i.e the slash character).

This comment has more details: #2622 (comment)

For your code, I don't know what cdn.test.com is but I assume changing the PutRequest to the following should work:

var putRequest = new PutObjectRequest
{
    BucketName = "cdn.test.com",
    Key = $"vcards/{fileName}.vcf",
    InputStream = stream,
    ContentType = "text/x-vcard"
};
