在python中处理服务器端的HTTP GET输入参数

F. *_*mir 20 python webserver get http

我用Python编写了一个简单的HTTP客户端和服务器进行实验.下面的第一个代码片段显示了我如何使用名为imsi的参数发送HTTP GET请求.在第二个代码片段中,我在服务器端显示了我的do_Get函数实现.我的问题是如何在服务器代码中提取imsi参数并将响应发送回客户端,以便向客户端发出imsi有效的信号.
谢谢.

PS:我验证了客户端成功发送请求.

CLIENT代码段

    params = urllib.urlencode({'imsi': str(imsi)})
    conn = httplib.HTTPConnection(host + ':' + str(port))
    #conn.set_debuglevel(1)
    conn.request("GET", "/index.htm", 'imsi=' + str(imsi))
    r = conn.getresponse()

您可以使用urlparse解析GET请求的查询,然后拆分查询字符串.

from urlparse import urlparse
query = urlparse(self.path).query
query_components = dict(qc.split("=") for qc in query.split("&"))
imsi = query_components["imsi"]
# query_components = { "imsi" : "Hello" }

# Or use the parse_qs method
from urlparse import urlparse, parse_qs
query_components = parse_qs(urlparse(self.path).query)
imsi = query_components["imsi"] 
# query_components = { "imsi" : ["Hello"] }

  • 使用Python 3,使用`from urllib.parse import urlparse` source:/sf/answers/366771611/ (5认同)

BaseHTTPServer是一个非常低级别的服务器.一般来说,你想使用一个真正的网络框架为你做这种笨拙的工作,但既然你问...

首先导入一个url解析库.在Python 2中,x是urlparse.(在Python3中,你使用urllib.parse)

import urlparse

然后,在do_get方法中,解析查询字符串.

imsi = urlparse.parse_qs(urlparse.urlparse(self.path).query).get('imsi', None)
print imsi  # Prints None or the string value of imsi

此外,您可能在您的客户端代码中使用urllib,它可能会更容易.
