如何使用Python的BaseHTTPServer/SimpleHTTPServer调试POST请求？

{'client_address': ('127.0.0.1', 53373), 'close_connection': 1, 'command': 'GET', 'connection': <socket._socketobject object at 0x10b6560c0>, 'headers': <mimetools.Message instance at 0x10b689ab8>, 'path': '/favicon.ico', 'raw_requestline': 'GET /favicon.ico HTTP/1.1\r\n', 'request': <socket._socketobject object at 0x10b6560c0>, 'request_version': 'HTTP/1.1', 'requestline': 'GET /favicon.ico HTTP/1.1', 'rfile': <socket._fileobject object at 0x10b6538d0>, 'server': <BaseHTTPServer.HTTPServer instance at 0x10b6893f8>, 'wfile': <socket._fileobject object at 0x10b6536d0>}

#!/usr/bin/python import time import BaseHTTPServer from pprint import pprint HOST_NAME = 'localhost' # !!!REMEMBER TO CHANGE THIS!!! PORT_NUMBER = 9000 # Maybe set this to 9000. class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler): def do_HEAD(s): s.send_response(200) s.send_header("Content-type", "text/html") s.end_headers() def do_GET(s): """Respond to a GET request.""" s.send_response(200) s.send_header("Content-type", "text/html") s.end_headers() s.wfile.write("<html><head><title>Title goes here.</title></head>") s.wfile.write("<body><form action='.' method='POST'><input name='x' value='1' /><input type='submit' /></form><p>This is a test.</p>") # If someone went to "http://something.somewhere.net/foo/bar/", # then s.path equals "/foo/bar/". s.wfile.write("<p>GET: You accessed path: %s</p>" % s.path) s.wfile.write("</body></html>") pprint (vars(s)) def do_POST(s): """Respond to a POST request.""" s.send_response(200) s.send_header("Content-type", "text/html") s.end_headers() s.wfile.write("<html><head><title>Title goes here.</title></head>") s.wfile.write("<body><p>This is a test.</p>") s.wfile.write("<body><form action='.' method='POST'><input type='text' name='xxxxxxxxxxxx' value='0000000000000000000000' /><input type='submit' /></form><p>This is a test.</p>") # If someone went to "http://something.somewhere.net/foo/bar/", # then s.path equals "/foo/bar/". s.wfile.write("<p>POST: You accessed path: %s</p>" % s.path) s.wfile.write("</body></html>") pprint (vars(s)) pprint (vars(s.connection)) pprint (vars(s.headers)) pprint (vars(s.request)) pprint (vars(s.rfile)) pprint (vars(s.server)) pprint (vars(s.wfile)) pprint (vars(s.fp)) """pprint (vars(s.request))""" if __name__ == '__main__': server_class = BaseHTTPServer.HTTPServer httpd = server_class((HOST_NAME, PORT_NUMBER), MyHandler) print time.asctime(), "Server Starts - %s:%s" % (HOST_NAME, PORT_NUMBER) try: httpd.serve_forever() except keyboardInterrupt: pass httpd.server_close() print time.asctime(), "Server Stops - %s:%s" % (HOST_NAME, PORT_NUMBER)

这并不十分明显，但处理程序在幕后使用了套接字。所以您需要从套接字读取原始数据，然后对其进行解释。

使用^{}模块。

在Python 2中，您需要urlparse.parse_qs。
在Python 3中，库被重命名：您需要urllib.parse.parse_qs。

导入urlparse，然后修改do_POST方法，如下所示：

def do_POST(s):
        """Respond to a POST request."""

        # Extract and print the contents of the POST
        length = int(s.headers['Content-Length'])
        post_data = urlparse.parse_qs(s.rfile.read(length).decode('utf-8'))
        for key, value in post_data.iteritems():
            print "%s=%s" % (key, value)

        s.send_response(200)
        s.send_header("Content-type", "text/html")
        s.end_headers()
        ...

设置简单的测试客户端：

#!/usr/bin/env python

import urllib
import urllib2

url = 'http://localhost:9000'
post_dict = {'foo' : 1,
             'bar' : 2,
             'bis' : 3}

params = urllib.urlencode(post_dict)
post_req = urllib2.Request(url)
post_req.add_data(params)

response = urllib2.urlopen(post_req)
response_data = response.read()
response.close()
print response_data

启动服务器，然后运行客户端：

ire@localhost$ python http_server.py 
Wed Oct  3 21:38:51 2012 Server Starts - localhost:9000
foo=[u'1']
bar=[u'2']
bis=[u'3']

您可以使用cgi模块而不是urlparse。cgi实现即时后参数分析。使用经过良好测试的库似乎更好。

import cgi

def do_POST(self):
    form = cgi.FieldStorage(
        fp=self.rfile,
        headers=self.headers,
        environ={"REQUEST_METHOD": "POST"}
    )

    for item in form.list:
        print "%s=%s" % (item.name, item.value)
