Question

有人可以帮助我为s3存储桶中的文件生成预览URL吗？这些是我尝试过的事情

digest = OpenSSL::Digest::Digest.new('sha1')
expire_date = Time.now.utc.to_i + (2*24*60*60)
S3_BUCKET = "test-local"
S3_SECRET_ACCESS_KEY =  BW::Config.aws_access_key
path = "users/2/debts/7/sample.pdf"
can_string = "GET\n\n\n#{expire_date}\n/#{S3_BUCKET}/#{path}"
hmac = OpenSSL::HMAC.digest(digest, S3_SECRET_ACCESS_KEY, can_string)
signature = URI.escape(Base64.encode64(hmac).strip)
"https://#{S3_BUCKET}.s3.amazonaws.com/#{path}?AWSAccessKeyId=#{S3_SECRET_ACCESS_KEY}&Expires=#{expire_date}&Signature=#{signature}"

使用此代码，我会收到类似

的错误
