from urllib import urlopen
doc = urlopen ( "http://HdhCmsTestbaidu测试数据" ) . read ()
print doc
doc = urlopen ( "http://HdhCmsTestbaidu测试数据" ) . read ()
print doc
二、获取Http头
from urllib import urlopen
doc = urlopen ( "http://HdhCmsTestbaidu测试数据" )
print doc . info ()
print doc . info () . getheader ( 'Content-Type' )
doc = urlopen ( "http://HdhCmsTestbaidu测试数据" )
print doc . info ()
print doc . info () . getheader ( 'Content-Type' )
三、使用代理
1. 查看环境变量
print " "n " . join ([ " %s = %s " % ( k , v ) for k , v in os . environ . items ()])
print os . getenv ( "http_proxy" )
print os . getenv ( "http_proxy" )
2. 设置环境变量
import os
os . putenv ( "http_proxy" , "http://proxyaddr:" )
os . putenv ( "http_proxy" , "http://proxyaddr:
3. 使用代理
# Use http://HdhCmsTestsomeproxy测试数据:3128 for http proxying
proxies = { 'http' : 'http://HdhCmsTestsomeproxy测试数据:3128' }
filehandle = urllib . urlopen ( some_url , proxies = proxies )
# Don't use any proxies
filehandle = urllib . urlopen ( some_url , proxies = {})
# Use proxies from environment - both versions are equivalent
filehandle = urllib . urlopen ( some_url , proxies = None )
filehandle = urllib . urlopen ( some_url )
proxies = { 'http' : 'http://HdhCmsTestsomeproxy测试数据:3128' }
filehandle = urllib . urlopen ( some_url , proxies = proxies )
# Don't use any proxies
filehandle = urllib . urlopen ( some_url , proxies = {})
# Use proxies from environment - both versions are equivalent
filehandle = urllib . urlopen ( some_url , proxies = None )
filehandle = urllib . urlopen ( some_url )
