Python自动刷新ajax?

Question

我刮了cricbuzz网站查看分数和其他细节..它将显示分数与一些细节每30秒…如何自动更新，如果分数在cricbuzz网站通过ajax的变化。。。有模块吗？你知道吗

    from urllib.request import urlopen
from bs4 import BeautifulSoup
import re
import time
while True:


    html = urlopen("http://www.cricbuzz.com/live-cricket-scores/16478/aus-vs-nz-1st-odi-new-zealand-tour-of-australia-2016")
    bsObj= BeautifulSoup(html,"html5lib")
#print(bsObj.prettify())
    players=[]
    detail=[]
    scores =bsObj.find("span",{"class":"cb-font-20 text-bold"})
    print(scores.get_text())
    detail.append(scores.get_text())
    status=bsObj.find("div",{"class":{"cb-text-inprogress","cb-text-lunch","cb-text-stump","cb-text-innings break","cb-text-tea"}})
    print("Status: ")
    print(status.get_text())
    detail.append(status.get_text())
    for link in bsObj.find('div', {"class":"cb-min-inf cb-col-100"}).find("div").next_siblings:
        if link.a.get_text() not in players:
            players.append(link.a.get_text())
            players.append(link.find('div',{"class":"cb-col cb-col-10 ab text-right"}).string)
    print("Players: ")                    
    for i in players:
        print(i)
    detail.append(players)
    print(detail)

    print("-----------------------------------------------------------------------------------")
    time.sleep(30)

因此，如果您愿意从http://www.cricbuzz.com/live-cricket-scores/16478/aus-vs-nz-1st-odi-new-zealand-tour-of-australia-2016获取实时游戏信息，那么该url就不是您想要一直请求的确切页面。你知道吗

基本上如您所说，该页面是由ajax请求更新的，所以您希望遵循特定的ajax url，在本例中是http://push.cricbuzz.com/match-push?id=16478，它是一个JSON就绪的对象，这有多好？你知道吗

现在只需使用json模块来解析它并提取您想要的任何内容。你知道吗
