我是 Python 的新手,我一直在尝试使用 BeautifulSoup 从脚本元素中定义的变量中提取一个特定的数据行。
代码:
import requests
from bs4 import BeautifulSoup
import esprima
#----------------some comment'
URL = 'https://downdetector.com/status/facebook/'
browser = {'user-agent': 'my agent'}
#--------------some comment:
page = requests.get(URL, headers=browser)
soup = BeautifulSoup(page.content, 'html.parser')
#---------------some comment:
chart = soup.find("div",{"class":"popover-container justify-content-center p-relative"}).script.get_text()
print(chart)
输出:
var data = {
status: 'success',
baseline: 29,
communicate: null,
company: 'Facebook',
max: 66,
series: [
{ x: '2020-05-30T13:22:28.168484-04:00', y: 25 },
{ x: '2020-05-30T13:37:28.168484-04:00', y: 27 },
.....
{ x: '2020-05-31T13:07:28.168484-04:00', y: 30 },
]
}
$(function () {
chartThis(data, 'holder', 'line')
});
if (data.communicate && $('#dd-communicate').length) {
$('#dd-communicate').html('<div class="border text-left d-inline-block p-2"><i class="fa" aria-hidden="true" style="color: red; width:16px; height:12px; background:url(https://cdn2.downdetector.com/d328eb8cbe4e164/images/v2/message.svg) no-repeat"></i>'
+'<span class="d-inline-block px-1">'+ data.company+' • ' + moment.utc(data.communicate.created_at).fromNow()
+ '</span><p class="font-weight-bold my-0">'+ data.communicate.message + '</p></div>')
}
你知道从上面的 var 结果中提取“最大”值的简单方法吗?
我试过使用 esprima,但仍然没有成功,因为我遇到了错误:
追溯(最近一次调用最后一次):文件“c:/test.py,第 31 行,在 if token[”type“] == “Identifier” and token [“value”] == “max”: TypeError: 'BufferEntry ' 对象不可订阅
