#!/usr/bin/env python

from wsgiref.simple_server import make_server

def app(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/plain')])
    return repr(environ['wsgi.input'].readlines()),

make_server('127.63.31.15', 54321, app).serve_forever()

当我启动此脚本并尝试通过cURL连接时：

curl -LvA Mozilla/4.0 -d lol=cat $'http://127.63.31.15:54321/'
*   Trying 127.63.31.15...
* Connected to 127.63.31.15 (127.63.31.15) port 54321 (#0)

> Accept: */*

......它只是挂起。我做错了什么？
