先给上代码

def log(content, file='test.log', type=1):    if type == 1:        f = open(file, 'a+', encoding='utf-8')    else:        f = open(file, 'w+', encoding='utf-8')    f.write(content)import urllib,re,http.cookiejar#建立带有cookie的openercookie = http.cookiejar.CookieJar()handler = urllib.request.HTTPCookieProcessor(cookie)opener = urllib.request.build_opener(handler)#opener=urllib2.build_opener()#opener.add_handler(cookieProc)#opener.addheaders(headers)h = opener.open('https://passport.csdn.net').read().decode("utf8")patten1 = re.compile(r'name="lt" value="(.*?)"')patten2 = re.compile(r'name="execution" value="(.*?)"')# b1 = patten1.findall(h)# b2 = patten2.findall(h)# print(h)postData = {    'username': 'username',    'password': 'password',    'lt': b1[0],    'execution': b2[0],    '_eventId': 'submit',}postData= urllib.parse.urlencode(postData).encode(encoding='UTF8')opener.addheaders = [('User-Agent',                      'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36'),                     ('Referer', 'https://passport.csdn.net/account/login?from=http://my.csdn.net/my/mycsdn')                     ]response = opener.open('https://passport.csdn.net', data=postData)text = response.read()# print(text)# exit()response2 = opener.open('http://my.csdn.net/my/mycsdn')text2 = response2.read().decode('utf-8', 'ignore')log(text2, 'csdn_mycsdn.html')

下面对程序中的函数做一些说明

cookie = http.cookiejar.CookieJar()

handler = urllib.request.HTTPCookieProcessor(cookie)

opener = urllib.request.build_opener(handler)

这三个函数先创建一个CookieJar类，再是实例化一个全局opener

postData= urllib.parse.urlencode(postData).encode(encoding='UTF8')

将字符串按照UTF8编码

第一次写博客还望见谅
