NBA球员信息获取

昨天介绍了一个不用写代码的web项目，今天说一下数据的获取。

球员信息​网站：https://nba.hupu.com/players/

 

​首先进行页面的分析：

此图片的url：https://nba.hupu.com/players/

 

点击左边的球队url会根据球队的不同进行相应的变化：

因此，我们只需要获取到所有的球队名称就能获取到所有的url信息了。

此时查看一下球队信息，对页面进行分析：

此处有球队详情的url：https://nba.hupu.com/teams/pelicans和球员信息的url比对https://nba.hupu.com/players/pelicans

发现只要将teams替换为players就获取到所有的url了

 

第二步：代码实现

import requests
from lxml import etree

def get_url(url):
    response = requests.get(url, headers).text
    dom = etree.HTML(response)
    player_urls = dom.xpath('//*[@class="team"]//a/@href')
    for player_url in player_urls:
        player_url = "".join(player_url).replace("teams","players")
        get_player(player_url)

def get_player(url):
    response = requests.get(url,headers).text
    dom = etree.HTML(response)
    players = dom.xpath('//*[@class="players_table"]/tbody//tr')
    for player in players[1:]:
        cname = player.xpath('./td/b/a/text()')
        ename = player.xpath('./td/p/b/text()')
        num = player.xpath('./td[3]/text()')
        place = player.xpath('./td[4]/text()')
        height = player.xpath('./td[5]/text()')
        weight = player.xpath('./td[6]/text()')
        birth = player.xpath('./td[7]/text()')
        ht = player.xpath('./td/b/text()')
        print(cname,ename,num,place,height,weight,birth,ht)


if __name__ == '__main__':
    url = 'https://nba.hupu.com/teams'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.193 Safari/537.36 Edg/86.0.622.68',
    }
    get_url(url)

　　结果展示：

一共获取了500名球员信息。
