代码示例：
object key := "+.pdf"
locaFilename := "+.pdf"
bucket.PutObjectFromFile(objectKey , locaFilename)

报错：
oss: service returned error: StatusCode=403, ErrorCode=SignatureDoesNotMatch, ErrorMessage="The request signature we calculated does not match the signature you provided. Check your key and signing method.",
