    Right now, it seems impossible to use cgi.FieldStorage in 3.0 if you're
    giving it environ['wsgi.input'] like so:

        post_data = cgi.FieldStorage(
        fp=environ["wsgi.input"],
        environ=environ,
        keep_blank_values=True
        )

    It gives the following error:

      File "/usr/local/lib/python3.0/cgi.py", line 489, in \_\_init__
    self.read_urlencoded()
  File "/usr/local/lib/python3.0/cgi.py", line 589, in read_urlencoded
    self.strict_parsing):
  File "/usr/local/lib/python3.0/urllib/parse.py", line 377, in

    parse_qsl
    pairs = [s2 for s1 in qs.split('&') for s2 in s1.split(';')]
    TypeError: Type str doesn't support the buffer API

    It is because FieldStorage requires str, whereas wsgi.input gives bytes.

    You can always wrap environ['wsgi.input'] in TextIOWrapper.
