进程和线程的任务切换由操作系统完成

协程任务之间的切换由程序(代码)完成,只有遇到协程模块能识别的IO操作的时候,程序才会进行任务切换,实现并发的效果

实例实现：

from gevent import monkey;

monkey.patch_all()
import requests

import time
import gevent

data = {'type': 'log', 'status': 'info', 'project_name': 'Project_0309_141331', 'project_desc': 'nan',
        'mac_addr': '70-B5-E8-2A-4C-B0', 'license_code': 'E9pO5YUqy5tCMfHcUkWc/A==',
        'studio_version': '2021/01/27 16:16:27 Build', 'case_name': 'TEST1.py', 'case_result': 'FAIL',
        'case_cost_time': '2', 'api_name': 'sleep', 'api_result': 'PASS', 'api_cost_time': '0.401',
        'create_time': '20210316103249'}


def task(n):
    # time.sleep(1)
    res = requests.post(url="https://www.baidu.com", json=data, timeout=1)
    if res.status_code != 200:
        # do_bak()
        print("失败，备份数据")

def asyncc():
    g_lst = []
    for i in range(10):
        g = gevent.spawn(task, i)
        g_lst.append(g)
    gevent.joinall(g_lst)  # for g in g_lst:g.join()
