NBA季后赛正在进行中,无奈要上班,不能看视频直播。而文字直播页面又有太多广告之类的东西,所以花半天时间,用Python 3搞一个基于命令行的文字直播,看着清爽,又不容易被领导发现。效果如图所示:
图1:程序启动时,列出当前所有比赛
图2:输入比赛ID后,文字直播来了
找了一圈NBA文字直播网站,发现手机版直播吧有现成的接口,直接返回json格式数据。那就是它了,听我慢慢道来。
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",
...
}
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
]
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.py
class 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)
再定义一个TextLiving
类,表示获取的每一条文字直播。
# text_living.py
class 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)
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_sid
Match_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 matches
def 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 texts
def 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_info
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 matches
def get_watch_match(matches):
match_id = input('请输入比赛ID:')
for match in matches:
if match.id == match_id:
return match
else:
print('输入的ID不正确')
return None
def 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()
程序中基本没做异常处理,还有很多需要改进的地方,欢迎大家指教。如果有朋友需要,我会把代码放在GitHub上。
