使用了多进程，调用requests发送请求，报错递归超过最大深度

====================报错信息==========
File "D:\Python36\lib\ssl.py", line 465, in options
    super(SSLContext, SSLContext).options.__set__(self, value)
  [Previous line repeated 321 more times]
RecursionError: maximum recursion depth exceeded while calling a Python object



==================多进程============

p = Pool(4)
res_list = []
for i in token_list:
    res = p.apply_async(create_app_fun, args=(i,))
    res_list.append(res)
p.close()
p.join()

======================被掉函数=========

def create_app_fun(token):
    url = base_url + WebApi.create_app
    data = {}
    headers = {'token': token}
    res = requests.post(url=url, json=data, headers=headers)
    return taskno

解决办法：

import gevent        #在requests调用之前先导入gevent
import requests
