一、python获取json数据
import urllib.request
def get_exchange_list():
exchanges_list = json.loads(urllib.request.urlopen('http://q.botvs.net/api/symbols').read())
return exchanges_list
报错：TypeError: the JSON object must be str, not 'bytes'，意思为json对象必须为字符串类型，而不是字节类型
def get_exchange_list():
exchanges_list = json.loads(urllib.request.urlopen('http://q.botvs.net/api/symbols').read().decode("utf-8"))
return exchanges_list
问题解决
二、python ping ip
import os,datetime,time
def run():
ip1 = "www.baidu.com"
backinfo = os.system("ping -w 1 %s" % ip1)
if backinfo != 0:
with open("app.txt", "a") as f:
f.write(str(datetime.datetime.now()) + "--" + str(ip1) + "--" + str(backinfo) + "\n")
f.close()
if __name__ == '__main__':
while True:
run()
time.sleep(60)
