首先在电脑浏览器打开手机版直播吧,我用的是chrome浏览器,在Network中可以看到,它不停地用GET方式请求http://bifen4m.qiumibao.com/json/list.htm,这个地址会返回当前正在进行的所有类型比赛的基本情况,根据其中的type字段过滤掉非NBA比赛就OK了。其中最重要的是ID字段,之后的所有操作都需要用到。返回的数据如下所示:
{
"code": "2760624",
"second": "10",
"list": [
{
"id": "96233",
"sdate": "2017-04-20",
"time": "10:30",
"url": "/zhibo/nba/2017/042096233.htm",
"type": "basketball",
"start": "2017-04-20 10:30",
"home_team": "勇士",
"visit_team": "开拓者",
"home_score": "106",
"visit_score": "81",
"period_cn": "第4节\n01:30",
"from": "dc.live",
"code": "373",
"update": "13:13:37",
"big_score_1": "",
"big_score_2": ""
},
... # 省略了其它比赛的信息

获得所有正在进行的比赛ID后,点击某一场比赛,进入文字直播页面。首先请求http://dingshi4pc.qiumibao.com/livetext/data/cache/max_sid/XXXX/0.htm页面,其中XXXX是上一步获取的id,它会返回一个数字,即max_sid。然后判断该max_sid是否大于上次获取的该值,如果大于,表示有新的直播文字,否则表示没有。
如果max_sid大于上一次的值,通过请求http://bifen4pc2.qiumibao.com/json/XXXX/YYYY.htm(其中XXXX是今天的日期,格式为2017-04-20,YYYY是第一步中获取的id),返回这场比赛的基本情况,比如比分,是第几节等,如下所示:
{"id": "96233","home_team": "勇士","visit_team": "开拓者","home_score": "110","visit_score": "81","period_cn": "第4节结束",...}123456789
最后,就可以获取直播的文字了。请求http://dingshi4pc.qiumibao.com/livetext/data/cache/livetext/XXXX/0/lit_page_2/YYYY.htm(其中XXXX是比赛id,YYYY是max_sid),它会返回最新的直播文字,其中包括一条或多条直播文字,如下所示:
[
{"live_id": "8769977","live_text": "@仙女最库阿-:库里正负值最高32我去!!!!","home_score": "110","visit_score": "81","pid_text": "比赛结束",...
},... # 可能有多条直播文字]1234567891011
可以看到,该请求返回的信息中没有比赛剩余时间、主队和客队等信息,所以每次获取直播文字之前,需要多一次请求,获得比赛的基本信息。
基本流程就是这样,非常简单,一共就四个GET请求,返回四串json,用requests库请求,然后解析搞定。
先定义一个Match类,表示当前正在进行的每一场比赛。
# match.pyclass Match:
def __init__(self, **kwargs):
self.id = kwargs['id']
self.home_team = kwargs['home_team']
self.visit_team = kwargs['visit_team']
self.home_score = kwargs['home_score']
self.visit_score = kwargs['visit_score']
self.period_cn = kwargs['period_cn'].replace('\n', ' ')def __repr__(self):
return '{self.id} {self.home_team} {self.home_score} - {self.visit_score} {self.visit_team} {self.period_cn}'.format(self=self)12345678910111213
再定义一个TextLiving类,表示获取的每一条文字直播。
# text_living.pyclass TextLiving:
def __init__(self, match_info, **kwargs):
self.home_team = match_info['home_team']
self.visit_team = match_info['visit_team']
self.period_cn = match_info['period_cn']
self.live_text = kwargs['live_text']
self.home_score = kwargs['home_score']
self.visit_score = kwargs['visit_score']def __repr__(self):
return '{self.home_team} {self.home_score} - {self.visit_score} {self.visit_team} {self.period_cn}\n{self.live_text}\n{sep}'.format(self=self, sep='*'*60)12345678910111213
接着创建zhibo8_api.py模块,用于获取相关数据。
# 当前正在进行的比赛Living_Matches_Url = 'http://bifen4m.qiumibao.com/json/list.htm'# 某一场比赛当前的max_sidMatch_Max_Sid_Url = 'http://dingshi4pc.qiumibao.com/livetext/data/cache/max_sid/%s/0.htm'# 某一场比赛最新文字直播Match_Living_Text_Url = 'http://dingshi4pc.qiumibao.com/livetext/data/cache/livetext/%s/0/lit_page_2/%d.htm'# 某一场比赛当前的基本情况Match_Info_Url = 'http://bifen4pc2.qiumibao.com/json/%s/%s.htm'def get_living_matches():
response = requests.get(Living_Matches_Url)
result = json.loads(response.text)
matches = [Match(**match) for match in result['list'] if match['type'] == 'basketball' and match['period_cn'] != '完赛']return matchesdef get_match_max_sid(match_id):
response = requests.get(Match_Max_Sid_Url % match_id)if response.status_code == requests.codes.ok:return int(response.text)def get_match_living(match_id, max_sid):
# 先获取比赛的当前情况,再获取最新文字直播
match_info = get_match_info(match_id)
response = requests.get(Match_Living_Text_Url % (match_id, max_sid))
texts = []if response.status_code == requests.codes.ok:
result = json.loads(response.text)
texts = [TextLiving(match_info, **living) for living in result]return textsdef get_match_info(match_id):
today = datetime.now().strftime('%Y-%m-%d')
response = requests.get(Match_Info_Url % (today, match_id))
match_info = json.loads(response.text)return match_info123456789101112131415161718192021222324252627282930313233343536373839404142
最后,在main.py模块中启动程序,开始直播!
def get_living_matches():
matches = zhibo8_api.get_living_matches()for match in matches:
print(match)return matchesdef get_watch_match(matches):
match_id = input('请输入比赛ID:')for match in matches:if match.id == match_id:return matchelse:
print('输入的ID不正确')return Nonedef main_loop():
matches = get_living_matches()if len(matches) == 0:
print('当前没有比赛!!!')return
match = get_watch_match(matches)if not match:
print('没去找到该比赛')return
current_match_max_sid = -1
while True:
match_max_sid = zhibo8_api.get_match_max_sid(match.id)if not match_max_sid:
print('没有直播数据')return
if current_match_max_sid == match_max_sid:continue
current_match_max_sid = match_max_sid
text_livings = zhibo8_api.get_match_living(match.id, current_match_max_sid)for text in text_livings:
print(text)if __name__ == '__main__':
main_loop()
零基础学习python的时间分为两种情况,一种是自学,自学一般周期时间比较长,差不多需要一年左右,当然也是因人而异的,接受能力强,自控能力好,有计划和规划,学习起来自然短一些,不过自学python的人,半途而废的人比较多,这点需要考虑清楚。第二种情况就是报名培训机构进行学习,这种学习一般都是比较系统化的,而且更加贴合企业的需求,学习过程也简单一些,有学习环境和氛围,学习周期在5-6个月。
