Python:setuptool.extern.six.moves.http_client模块的高级技巧和用法

setuptools.extern.six.moves.http_client模块是six库中的一部分，用于在Python 2和Python 3之间提供兼容性。该模块提供了HTTP客户端的高级技巧和用法，可以用于发送HTTP请求，处理响应和处理异常。

以下是使用setuptools.extern.six.moves.http_client模块的高级技巧和用法的示例：

1. 发送GET请求：

import httplib

conn = httplib.HTTPConnection("www.example.com")
conn.request("GET", "/")
response = conn.getresponse()
print(response.status, response.reason)
data = response.read()
conn.close()

2. 发送POST请求：

import httplib
import urllib

params = urllib.urlencode({'param1': 'value1', 'param2': 'value2'})
headers = {"Content-type": "application/x-www-form-urlencoded"}
conn = httplib.HTTPConnection("www.example.com")
conn.request("POST", "/", params, headers)
response = conn.getresponse()
print(response.status, response.reason)
data = response.read()
conn.close()

3. 处理重定向：

import httplib

conn = httplib.HTTPConnection("www.example.com")
conn.request("GET", "/path", headers={"Host": "www.example.com"})
response = conn.getresponse()
if response.status == 302:
    redirect_location = response.getheader("Location")
    conn.close()
    conn = httplib.HTTPConnection("www.example.com")
    conn.request("GET", redirect_location, headers={"Host": "www.example.com"})
    response = conn.getresponse()
print(response.status, response.reason)
data = response.read()
conn.close()

4. 处理HTTP异常：

import httplib

try:
    conn = httplib.HTTPConnection("www.example.com")
    conn.request("GET", "/nonexistent")
    response = conn.getresponse()
    print(response.status, response.reason)
    data = response.read()
except httplib.HTTPException as e:
    print("HTTPException: %s" % str(e))
finally:
    conn.close()

以上示例演示了使用setuptools.extern.six.moves.http_client模块发送HTTP请求，处理响应，处理重定向和处理HTTP异常的技巧和用法。您可以根据自己的需求进行相应的调整和修改。
