'NoneType' 对象在尝试检索 Table 数据时没有属性 'text'

Question

人们已经问过 100 次类似的问题，但 none 的解决方案正在解决我的问题！我创建了一个 html 文档，我正在托管 github，上面有一个 table！ table 将用于存储玩家用户名、密码和用户 ID。网络抓取在我正在处理的整个其他项目上进展顺利，但在这里不起作用！

下面我放了 Python 脚本，它正在抓取我创建的网站！

from bs4 import BeautifulSoup
import requests


def getData():
    url = 'https://galaxy-indie-studio.github.io/Galaxy-Indie-Studio-Website/database.html'
    html_url = requests.get(url).text
    soup = BeautifulSoup(html_url, "lxml")

    database = soup.find_all('tr', class_="Player")

    for Players in database:
        username = Players.find('td', class_="Username").text 
        password = Players.find('td', class_="Password").text
        userID = Players.find('td', class_="UserID").text

        print(f"Username in database {username}")
        print(f"Password in database {password}")
        print(f"UserID in database {userID}")

如果我将 .text 留在我收到的任何变量的末尾，我会收到 AttributeError: 'NoneType' object has no attribute。如果我删除 .text it returns 为 None，用户名、密码和用户 ID 相同

在下面，我输入了我目前用于存储 table 的网站的代码！

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>Player Database</title>
    </head>
    <body>
        <table border = 4px, bgcolor="black", width= 100%> 
            <tr>
                <th width="150" height="20" bgcolor="lightgray">Username</th>
                <th width="150" height="20" bgcolor="lightgray">Password</th>
                <th width="150" height="20" bgcolor="lightgray">UserID</th>
            </tr>
            <tr class="Player", width="150" height="20">
                <td align="center" bgcolor="lightgray",class="Username">BigTall12</td>
                <td align = "center" bgcolor="lightgray",class="Password"></td>
                <td align="center" bgcolor="lightgray",class="UserID"></td>
            </tr>

            <tr class="Player",width="150" height="20">
                <td align="center" bgcolor="lightgray",class="Username"></td>
                <td align = "center" bgcolor="lightgray",class="Password"></td>
                <td align = "center" bgcolor="lightgray",class="UserID"></td>
            </tr>

            <tr class="Player",width="150" height="20">
                <td align="center" bgcolor="lightgray",class="Username"></td>
                <td align="center" bgcolor="lightgray",class="Password"></td>
                <td align="center"bgcolor="lightgray",class="UserID"></td>
            </tr>

            <tr class="Player",width="150" height="20">
                <td align="center" bgcolor="lightgray",class="Username"></td>
                <td align="center" bgcolor="lightgray",class="Password"></td>
                <td align="center" bgcolor="lightgray",class="UserID"></td>
            </tr>

        </table>
    </body>
</html>

Answer 1

那是因为您在 <td> 标签中没有 class 属性。你确实有一个 ,class 属性，bs4 不会识别它。

所以我的意思是，您的 html 是错误的。去掉源 html.

中 class 属性前的那些逗号

例如：

`<td align="center" bgcolor="lightgray",class="Username">BigTall12</td>`

应该是

`<td align="center" bgcolor="lightgray" class="Username">BigTall12</td>`

或者，在阅读 html 后修复它：

import requests
from bs4 import BeautifulSoup

def getData():
    url = 'https://galaxy-indie-studio.github.io/Galaxy-Indie-Studio-Website/database.html'
    html_url = requests.get(url).text
    html_url = html_url.replace(',class', ' class')
    
    soup = BeautifulSoup(html_url, "lxml")

    database = soup.find_all('tr', class_="Player")

    for Players in database:
        username = Players.find('td', class_="Username").text 
        password = Players.find('td', class_="Password").text
        userID = Players.find('td', class_="UserID").text

        print(f"Username in database {username}")
        print(f"Password in database {password}")
        print(f"UserID in database {userID}")
        
        
getData()
