 MonkeyPatchWarning: Monkey-patching ssl after

报错原因： 导入包的顺序不正确；

解决： 正确顺序如下：

import gevent
from gevent import monkey
monkey.patch_all()

import requests　　

完整示例：

import gevent
from gevent import monkey
monkey.patch_all()

import requests



def task(method, url, req_kwargs):
    print(method, url, req_kwargs)
    response = requests.request(method=method, url=url, **req_kwargs)
    print(response.url, response.content)

# ##### 发送请求 #####
gevent.joinall([
    gevent.spawn(task, method='get', url='https://www.python.org/', req_kwargs={}),
    gevent.spawn(task, method='get', url='https://www.yahoo.com/', req_kwargs={}),
    gevent.spawn(task, method='get', url='https://github.com/', req_kwargs={}),
])
# ##### 发送请求（协程池控制最大协程数量） #####
# from gevent.pool import Pool
# pool = Pool(5)
# gevent.joinall([
#     pool.spawn(task, method='get', url='https://www.python.org/', req_kwargs={}),
#     pool.spawn(task, method='get', url='https://www.yahoo.com/', req_kwargs={}),
#     pool.spawn(task, method='get', url='https://www.github.com/', req_kwargs={}),
# ])
