monkey.patch_all()处理多线程问题

monkey解决方案

开多线程时monkey会阻塞住线程的继续执行，需要对monkey.patch_all进行处理，解决方案有2种：
1. monkey.patch_all(thread=False)
2. 直接用gevent.sleep()

from bs4 import BeautifulSoupimport requestsimport geventimport timefrom gevent import monkey, poolfrom threading import Threadmonkey.patch_all()jobs = []links = []p = pool.Pool(10)url = [    'http://www.baidu.com',]def get_links(url):    # time.sleep(2)    r = requests.get(url)    if r.status_code == 200:        soup = BeautifulSoup(r.text, 'lxml')        print('>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>')        links + soup.find_all('a')def start_process():    time.sleep(2)    # for url in urls:    #     jobs.append(p.spawn(get_links, url))    # gevent.joinall(jobs)if __name__ == '__main__':    t = Thread(target=start_process, )    t.start()    t.join()

上面的例子会卡住，具体解释见StackOverflow链接~
