學完前面的教程，相信你已經能爬取大部分的網站信息了，但是當你爬的網站多了，你應該會發現一個新問題，有的網站需要登錄賬戶才能看到更多的信息對吧？那麼這種網站怎麼爬取呢？這些登錄數據就是今天要說的——cookie
cookie
其實在前面在解析requests模塊時也提到過的。
Cookie，指某些網站為了辨別用戶身份、進行session跟蹤而儲存在用戶本地終端上的數據（通常經過加密），比如說有些網站需要登錄後才能訪問某個頁面，在登錄之前，你想抓取某個頁面內容是不允許的。這也是放爬蟲的一種手段，但是怎麼可能難道我們呢？對吧？我們可以利用Urllib2庫保存我們登錄的Cookie，然後再抓取其他頁面就達到目的了
既然已經知道cookie是登錄賬戶信息，我們怎麼利用它進行爬取網站呢？這裡就要用到一個內置模塊——cookielib
cookielib
1.簡介：
cookielib模塊的主要作用是提供可存儲cookie的對象，以便於與urllib2模塊配合使用來訪問Internet資源。
Cookielib模塊非常強大，可以利用它的CookieJar類的對象來捕獲cookie併在後續連接請求時重新發送，比如可以實現模擬登錄功能
該模塊主要的對象有CookieJar、FileCookieJar、MozillaCookieJar、LWPCookieJar。
其關係為：CookieJar —-派生—->FileCookieJar —-派生—–>MozillaCookieJar和LWPCookieJar
2.方法屬性：
註意：這裡使用的是python2，cookielib是內置模塊也是針對python2而言，在python3中，與cookielib模塊功能相同的是http.cookiejar模塊
3.常用方法/屬性就略過，以後遇到再說，本篇博文直接以舉例來解析最常用的幾個方法
1）獲取Cookie
import cookielib
import urllib2
cookie = cookielib.CookieJar() #創建CookieJar對象實例來保存cookie
handler=urllib2.HTTPCookieProcessor(cookie) #利用urllib2庫的HTTPCookieProcessor對象創建cookie處理器
opener = urllib2.build_opener(handler) #通過cookie處理器創建opener
response = opener.open('http://www.baidu.com') #此處的open方法類同urllib2的urlopen方法，也可以傳入request
for item in cookie:
print 'Name = '+item.name
print 'Value = '+item.value
結果：
上面的Name和Value就是cookie信息
註意：cookie並不是等同於賬戶密碼信息，而是包含賬戶密碼信息和其他信息
2）保存Cookie到文件
有時候根據開發需要，我們可能會想把cookie信息保存下來以便以後直接使用，相信大家平時上網訪問需要登錄賬戶的時候都是勾選了記住帳號密碼的吧？
當勾選了這個選項，瀏覽器就會把賬戶和密碼作為cookie信息保存在瀏覽器的本地數據內，以後再訪問，直接自動登錄
利用python其實也可以實現這個功能
import cookielib
import urllib2
filename = 'cookie.txt' #設置保存cookie的文件，預設保存在當前目錄
cookie = cookielib.MozillaCookieJar(filename) #創建一個MozillaCookieJar對象實例來保存cookie，MozillaCookieJar對象會自動完成創建和寫入操作
handler = urllib2.HTTPCookieProcessor(cookie) #利用urllib2庫的HTTPCookieProcessor對象來創建cookie處理器
opener = urllib2.build_opener(handler) #通過cookie處理器創建opener
response = opener.open("http://www.baidu.com") #創建一個請求
cookie.save(ignore_discard=True, ignore_expires=True) #保存cookie到文件
這裡的save方法要說一下，它有兩個參數：
- ignore_discard：即使cookies將被丟棄也將它保存下來
- ignore_expires：如果在該文件中cookies已經存在，則覆蓋原文件寫入（類似文件操作模式里的'W'）
打開cookie.txt文件：
# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This is a generated file! Do not edit.
.baidu.com TRUE / FALSE 3658914970 BAIDUID F6DCF3EE6D6624B9CDE48E6CDF1186F0:FG=1
.baidu.com TRUE / FALSE 3658914970 BIDUPSID F6DCF3EE6D6624B9CDE48E6CDF1186F0
.baidu.com TRUE / FALSE H_PS_PSSID 1441_21109_18559_25178_20927
.baidu.com TRUE / FALSE 3658914970 PSTM 1511431348
www.baidu.com FALSE / FALSE BDSVRTM 0
www.baidu.com FALSE / FALSE BD_HOME 0
以上就是cookie信息
3）從文件中獲取Cookie並訪問
既然有保存到文件，那麼自然有逆操作，利用已有的cookie文件的來傳入數據
import cookielib
import urllib2
cookie = cookielib.MozillaCookieJar() #創建MozillaCookieJar實例對象
cookie.load('cookie.txt', ignore_discard=True, ignore_expires=True) #從當前目錄下的cookie.txt文件中讀取cookie內容到變數
url = "http://www.baidu.com"
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie)) #利用urllib2的build_opener方法創建一個opener
response = opener.open(url)
print response.read()
結果：
<!--STATUS OK-->
