前言
本篇博客是python开发的使用案例博客，结合一些具体的案例进行阐述，本篇博客主要内容是使用Python发送Get请求，模拟http请求，后面可以搞个爬虫出来，另外就是如何使用Python进行SSH连接服务器。
其他相关的博客文章如下：

引出
1.使用Python发送Get请求，模拟http请求；
2.如何使用Python进行SSH连接服务器；
python发送get请求
案例1：get请求，间隔1分钟查询，if语法打印
import requests
import time
from datetime import datetime
url=f'http://x.x.x.x:8082/sn' #格式化输出拼接
snTarget = "S231012J0029"
while(True):
response = requests.get(url=url)
snList = response.json()
current_time = datetime.now()
if snTarget in snList:
print("%s 查询到目标sn" %current_time)
else:
print("%s 未查到设备sn" %current_time)
time.sleep(60)
案例2：间隔一定时间，轮流进行get请求，总共2个
# encoding:utf-8
import requests
import time
from datetime import datetime
req3 = "http://xxxx"
req4 = "http://xxxx"
reqs = [req3, req4]
vers = ["2.0.3", "2.0.4"]
url = f'http://x.x.x.x:8082/sn' # 格式化输出拼接
snTarget = "S231012J0029"
while (True):
response = requests.get(url=url)
snList = response.json()
current_time = datetime.now()
if snTarget in snList:
print("%s 查询到目标sn" % current_time)
for ver, req in zip(vers, reqs):
print("{} 进行版本升级 {}".format(datetime.now(), ver))
# print("send request :", req)
resp = requests.get(url=req).json()
print(resp)
time.sleep(430)
else:
print("%s 未查到设备sn" % current_time)
time.sleep(60)
python进行SSH链接
