如何使用POST数据和Cookie制作Python HTTP请求？

我想在Python中使用cookie进行HTTP POST。如何使用POST数据和Cookie制作Python HTTP请求？

我有URL，POST数据和cookie的值。

import urllib2 
url="http://localhost/testing/posting.php" 
data="subject=Alice-subject&addbbcode18=%23444444&addbbcode20=0&helpbox=Close+all+open+bbCode+tags&message=alice-body&poll_title=&add_poll_option_text=&poll_length=&mode=newtopic&sid=5b2e663a3d724cc873053e7ca0f59bd0&f=1&post=Submit" 
cookie = "phpbb2mysql_data=a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%223%22%3B%7D; phpbb2mysql_t=a%3A9%3A%7Bi%3A3%3Bi%3A1330156986%3Bi%3A1%3Bi%3A1330160737%3Bi%3A5%3Bi%3A1330161702%3Bi%3A6%3Bi%3A1330179284%3Bi%3A2%3Bi%3A1330160743%3Bi%3A7%3Bi%3A1330163187%3Bi%3A8%3Bi%3A1330164442%3Bi%3A9%3Bi%3A1330164739%3Bi%3A10%3Bi%3A1330176335%3B%7D; phpbb2mysql_sid=5b2e663a3d724cc873053e7ca0f59bd0" 
#creating HTTP Req 
req = urllib2.Request(url,data,cookie) 

f = urllib2.urlopen(req) 
print f.read()

但是，如果我尝试运行程序，它抛出一个错误：

Traceback (most recent call last): 
    File "task-4.py", line 7, in <module> 
    req = urllib2.Request(url,data,cookie) 
    File "/usr/lib/python2.6/urllib2.py", line 197, in __init__ 
    for key, value in headers.items(): 
AttributeError: 'str' object has no attribute 'items'

我有两个问题：1。我是HTTP POST请求是否正确？（我已经能够在Java中执行相同的事情，并且获得了一个成功发布到phpBB的HTTP 200，但是，我是Python的新手） 2.有人可以给我看一个玩具示例，用POST数据处理HTTP POST和饼干？

由于提前，

罗伊

你可以试试请求，这使得在处理HTTP查询时生活更轻松。

import requests 
url="http://localhost/testing/posting.php" 
data= { 
    'subject': 'Alice-subject', 
    'addbbcode18': '%23444444', 
    'addbbcode20': '0', 
    'helpbox': 'Close all open bbCode tags', 
    'message': 'alice-body', 
    'poll_title': '', 
    'add_poll_option_text': '', 
    'poll_length': '', 
    'mode': 'newtopic', 
    'sid': '5b2e663a3d724cc873053e7ca0f59bd0', 
    'f': '1', 
    'post': 'Submit', 
    } 
cookies = {'phpbb2mysql_data': 'a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%223%22%3B%7D', 
    'phpbb2mysql_t': 'a%3A9%3A%7Bi%3A3%3Bi%3A1330156986%3Bi%3A1%3Bi%3A1330160737%3Bi%3A5%3Bi%3A1330161702%3Bi%3A6%3Bi%3A1330179284%3Bi%3A2%3Bi%3A1330160743%3Bi%3A7%3Bi%3A1330163187%3Bi%3A8%3Bi%3A1330164442%3Bi%3A9%3Bi%3A1330164739%3Bi%3A10%3Bi%3A1330176335%3B%7D', 
    'phpbb2mysql_sid': '5b2e663a3d724cc873053e7ca0f59bd0', 
    } 
print requests.get(url, data=data, cookies=cookies).text

你通过了第三个参数是一个头，应该是一个字典。这应该这样做

cookie = {"Cookie" : "phpbb2mysql_data=a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%223%22%3B%7D; phpbb2mysql_t=a%3A9%3A%7Bi%3A3%3Bi%3A1330156986%3Bi%3A1%3Bi%3A1330160737%3Bi%3A5%3Bi%3A1330161702%3Bi%3A6%3Bi%3A1330179284%3Bi%3A2%3Bi%3A1330160743%3Bi%3A7%3Bi%3A1330163187%3Bi%3A8%3Bi%3A1330164442%3Bi%3A9%3Bi%3A1330164739%3Bi%3A10%3Bi%3A1330176335%3B%7D; phpbb2mysql_sid=5b2e663a3d724cc873053e7ca0f59bd0"}

我喜欢httplib的：

from urlparse import urlparse 
from httplib import HTTPConnection 
url = "http://localhost/testing/posting.php" 
data = "subject=Alice-subject&addbbcode18=%23444444&addbbcode20=0&helpbox=Close+all+open+bbCode+tags&message=alice-body&poll_title=&add_poll_option_text=&poll_length=&mode=newtopic&sid=5b2e663a3d724cc873053e7ca0f59bd0&f=1&post=Submit" 
cookie = "phpbb2mysql_data=a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%223%22%3B%7D; phpbb2mysql_t=a%3A9%3A%7Bi%3A3%3Bi%3A1330156986%3Bi%3A1%3Bi%3A1330160737%3Bi%3A5%3Bi%3A1330161702%3Bi%3A6%3Bi%3A1330179284%3Bi%3A2%3Bi%3A1330160743%3Bi%3A7%3Bi%3A1330163187%3Bi%3A8%3Bi%3A1330164442%3Bi%3A9%3Bi%3A1330164739%3Bi%3A10%3Bi%3A1330176335%3B%7D; phpbb2mysql_sid=5b2e663a3d724cc873053e7ca0f59bd0" 
urlparts = urlparse(url) 
conn = HTTPConnection(urlparts.netloc, urlparts.port or 80) 
conn.request("POST", urlparts.path, data, {'Cookie': cookie}) 
resp = conn.getresponse() 
body = resp.read()

不是真的。该错误是因为urllib2库试图迭代你给它的cookie字符串的项目。尝试使用：

cookies = urllib.urlencode({'phpbb2mysql_data':'foo', 'autologinid':'blahblah'}) 
# Can do the same for data, allowing you to store it as a map. 
headers = {'Cookie': cookies} 
req = urllib2.Request(url, data, headers)

见python: urllib2 how to send cookie with urlopen request，但你最好的参考还是真的urllib2 Request docs，但肯定它是一个棘手的（但功能强大）库相比，一些较新的。
