前言
本篇博客是python開(kāi)發(fā)的使用案例博客，結(jié)合一些具體的案例進(jìn)行闡述，本篇博客主要內(nèi)容是使用Python發(fā)送Get請(qǐng)求，模擬http請(qǐng)求，后面可以搞個(gè)爬蟲(chóng)出來(lái)，另外就是如何使用Python進(jìn)行SSH連接服務(wù)器。
其他相關(guān)的博客文章如下：

1.使用Python發(fā)送Get請(qǐng)求，模擬http請(qǐng)求；
2.如何使用Python進(jìn)行SSH連接服務(wù)器；
python發(fā)送get請(qǐng)求
案例1：get請(qǐng)求，間隔1分鐘查詢，if語(yǔ)法打印
import requests
import time
from datetime import datetime
url=f'http://x.x.x.x:8082/sn' #格式化輸出拼接
snTarget = "S231012J0029"
while(True):
response = requests.get(url=url)
snList = response.json()
current_time = datetime.now()
if snTarget in snList:
print("%s 查詢到目標(biāo)sn" %current_time)
else:
print("%s 未查到設(shè)備sn" %current_time)
time.sleep(60)
案例2：間隔一定時(shí)間，輪流進(jìn)行g(shù)et請(qǐng)求，總共2個(gè)
# 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' # 格式化輸出拼接
snTarget = "S231012J0029"
while (True):
response = requests.get(url=url)
snList = response.json()
current_time = datetime.now()
if snTarget in snList:
print("%s 查詢到目標(biāo)sn" % current_time)
for ver, req in zip(vers, reqs):
print("{} 進(jìn)行版本升級(jí) {}".format(datetime.now(), ver))
# print("send request :", req)
resp = requests.get(url=req).json()
print(resp)
time.sleep(430)
else:
print("%s 未查到設(shè)備sn" % current_time)
time.sleep(60)
