如果你想要一个较低级别的API:

import http.client

conn = http.client.HTTPSConnection('example.com')
conn.request('GET', '/')

resp = conn.getresponse()
content = resp.read()

conn.close()

text = content.decode('utf-8')

print(text)

真是诡异啊

要使它与python 3一起工作，请进行以下更改

import sys, urllib.request

def reporthook(a, b, c):
    print ("% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c))
    sys.stdout.flush()
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print (url, "->", file)
    urllib.request.urlretrieve(url, file, reporthook)
print

此外，您输入的URL前面应该加上一个“http://”，否则将返回一个未知的URL类型错误。

如果你想解决方案与httplib2是联机考虑实例化匿名Http对象

import httplib2
resp, content = httplib2.Http().request("http://example.com/foo/bar")

没有进一步的必要导入，这个解决方案工作(对我来说)-也与https:

try:
    import urllib2 as urlreq # Python 2.x
except:
    import urllib.request as urlreq # Python 3.x
req = urlreq.Request("http://example.com/foo/bar")
req.add_header('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36')
urlreq.urlopen(req).read()

当没有在头信息中指定“User-Agent”时，我经常很难获取内容。然后通常用类似urllib2的代码取消请求。HTTP错误403:禁止或urllib.error.HTTPError: HTTP错误403:禁止。

如何也发送头

Python 3:

import urllib.request
contents = urllib.request.urlopen(urllib.request.Request(
    "https://api.github.com/repos/cirosantilli/linux-kernel-module-cheat/releases/latest",
    headers={"Accept" : 'application/vnd.github.full+json"text/html'}
)).read()
print(contents)

Python 2:

import urllib2
contents = urllib2.urlopen(urllib2.Request(
    "https://api.github.com",
    headers={"Accept" : 'application/vnd.github.full+json"text/html'}
)).read()
print(contents)

下面是Python中的wget脚本:

# From python cookbook, 2nd edition, page 487
import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print
