Take the code, only 10 pages are captured here, Add the cookies yourself

# coding=utf-8

from pyquery import PyQuery as Q
import requests, threading, time

session = requests.Session()
session.headers = {
    'Cookie':'',
    'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.63 Safari/537.36'
}

def get_title(titles, page):
    r = session.get('http://weibo.cn/gzyhl?page={0}'.format(page))
    html = r.text.encode('utf-8')
    for _ in Q(html).find('span.ctt'):
        titles.append(Q(_).text())

start = time.time()

result, threadPool = [], []
for page in range(1, 11):
    th = threading.Thread(target=get_title, args=(result, page))
    th.start()
    threadPool.append(th)

for th in threadPool:
    threading.Thread.join(th)

end = time.time()

print 'times: {0}, total: {1}'.format(end - start, len(result))
