假设您试图将POST数据仅获取到FieldStorage对象中：
# env is the environment handed to you by the WSGI server.# I am removing the query string from the env before passing it to the# FieldStorage so we only have POST data in there.post_env = env.copy()post_env['QUERY_STRING'] = ''post = cgi.FieldStorage( fp=env['wsgi.input'], environ=post_env, keep_blank_values=True)
