python - python中的抓取表

Question

有人可以帮我从https://www.statsinsider.com.au/prediction-results?fbclid=IwAR18wxeCq_ygxLG1v2JEe3YqBNNS6krzNnOQULYp4IZihQY6JMgHwzpIl6o上的大表中抓取数据

我在这里有一些基础：

from bs4 import BeautifulSoup
from requests_html import HTMLSession
session = HTMLSession()
url = 'https://www.statsinsider.com.au/prediction-results?fbclid=IwAR18wxeCq_ygxLG1v2JEe3YqBNNS6krzNnOQULYp4IZihQY6JMgHwzpIl6o'
r = session.get(url)
soup=BeautifulSoup(r.html.html,'html.parser')
stat_table = soup.find('table')

这会输出以下内容，这似乎不是整个表格。帮助表示赞赏，谢谢！

<table>
<tbody>
<tr>
<th>Date</th>
<th class="to-hide">Sport</th>
<th>Team</th>
<th class="to-hide">Bet Type</th>
<th>Odds</th>
<th class="to-hide">Bet</th>
<th>Result</th>
<th>Profit/Loss</th>
</tr>
<tr ng-repeat="match in recentResults">
<td>{{match.Date}}</td>
<td class="to-hide">{{match.Sport}}</td>
<td>{{match.Team}}</td>
<td class="to-hide">{{match.Type}}</td>
<td>${{match.Odds}}</td>
<td class="to-hide">${{match.Bet}}</td>
<td>{{match.Result}}</td>
<td class="green" ng-if="match.Return &gt; 0">${{match.Return}}</td>
<td class="red" ng-if="match.Return &lt; 0">${{match.Return}}</td>
<td ng-if="match.Return == 0"></td>
</tr>
</tbody>
</table>

Answer 1

该表是使用 AJAX 调用动态创建的。

该页面正在获取 3 个 JSON 文档 - 其中之一是您要查找的文档。

1. https://gazza.statsinsider.com.au/results.json?sport=NFL
2. https://gazza.statsinsider.com.au/sportladder.json?sport=nba
3. https://gazza.statsinsider.com.au/upcoming.json

您需要做的就是对上面的每个 URL 进行 HTTP GET 并检查其中哪一个是表格模式。找到正确的 URL 后，使用请求并获取数据。

Answer 2

由于您已经在使用请求，您可能需要考虑使用Requests-HTML。尽管它的功能不如selenium先进，但在您只想呈现页面的情况下，它非常有用。

安装

pip install requests-html

您提供的链接中的表格可以使用 Requests-HTML轻松抓取

代码：

from bs4 import BeautifulSoup
from requests_html import HTMLSession
session = HTMLSession()
url = 'https://www.statsinsider.com.au/prediction-results?fbclid=IwAR18wxeCq_ygxLG1v2JEe3YqBNNS6krzNnOQULYp4IZihQY6JMgHwzpIl6o'
r = session.get(url)
r.html.render()
soup=BeautifulSoup(r.html.html,'html.parser')
stat_table = soup.find('table')
print(stat_table)

输出

<table>
<tbody>
<tr>
<th>Date</th>
<th class="to-hide">Sport</th>
<th>Team</th>
<th class="to-hide">Bet Type</th>
<th>Odds</th>
<th class="to-hide">Bet</th>
<th>Result</th>
<th>Profit/Loss</th>
</tr>

...

<tr class="ng-scope" ng-repeat="match in recentResults">
<td class="ng-binding">17/09</td>
<td class="to-hide ng-binding">NFL</td>
<td class="ng-binding">NO</td>
<td class="to-hide ng-binding">Line</td>
<td class="ng-binding">$1.91</td>
<td class="to-hide ng-binding">$25</td>
<td class="ng-binding">LOSE</td>
<!-- ngIf: match.Return > 0 -->
<!-- ngIf: match.Return < 0 --><td class="red ng-binding ng-scope" ng-if="match.Return &lt; 0">$-25.00</td><!-- end ngIf: match.Return < 0 -->
<!-- ngIf: match.Return == 0 -->
</tr><!-- end ngRepeat: match in recentResults -->
</tbody>
