重要代码：

一.下载代码重要片段：

from urllib import request

resp = request.urlopen(url)
request.urlretrieve(url,ip+'.json')  # 用‘urllib’模块下载数据到本地为ret.json，里面

上述代码，把文件下载在本地‘ip.json’文件

二.读取代码，读取代码结合下载的接送数据内容进行分析，进行打印

with open(jsonpath,"r",encoding='utf-8')as fp:
    data=json.load(fp)
    # print(data)
    # print(type(data))  #dic字典类型
    arraydata=data["ListStream"]["lives"]    #列表数据
    # print(arrydata)
    # print(type(arrydata))

    for dicitem in arraydata:
        print(dicitem["channel"]["name"],"\t",dicitem["channel"]["id"],"\t",dicitem["client"]["host"])
