In a CGI application, you shouldn't be using sys.stdin or print(). Instead, you should be using sys.stdin.buffer (or sys.stdin.buffer.raw), and sys.stdout.buffer.raw. A CGI script essentially does binary IO; if you use TextIO, there likely will be bugs (e.g. if you have attachments of type application/octet-stream). > print("Content-Type: application/json; charset=utf-8") > input_object = json.loads(sys.stdin.read()) > output_object = do_some_work(input_object) > print(json.dumps(output_object)) > print() out = sys.stdout.buffer.raw out.write(b"Content-Type: application/json; charset=utf-8\n\n") input_object = json.loads(sys.stdin.buffer.raw.read()) output_object = do_some_work(input_object) out.write(json.dumps(output_object)) > What's the benefit of preventing users from getting a str out if that's > what they want? If they really want it, there is no benefit from preventing them. I'm just puzzled why they want it, and what possible applications might be where they want it. Perhaps they misunderstand something when they think they want it.
