Python获取Javascript变量的值

我正在抓取instagram页面（）并获取脚本（HTML和一些javascript）。结果是这样的

<script>some script</script>
<script>some script</script>
<script>some script</script>
<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>

import urllib.request
import json
import re
from bs4 import BeautifulSoup

web = urllib.request.urlopen("https://instagram.com/celmirashop")
soup = BeautifulSoup(web.read(), 'lxml')
pattern = re.compile(r"window._sharedData = .")
script = soup.find("script",text=pattern)
print(script)

<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>

给我一个结果，一个我想要的特定javascript。像这样

<script>some script</script>
<script>some script</script>
<script>some script</script>
<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>

import urllib.request
import json
import re
from bs4 import BeautifulSoup

web = urllib.request.urlopen("https://instagram.com/celmirashop")
soup = BeautifulSoup(web.read(), 'lxml')
pattern = re.compile(r"window._sharedData = .")
script = soup.find("script",text=pattern)
print(script)

<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>

window._sharedData={“config”：{“csrf_令牌”：“ssqrj6c8tfn1hwoilwmpqont2baptnu”，“查看器”：null等。。。。

如何获取window.\u sharedData？的值并循环它。因为我想在mysql中保存，假设以；结束，并且只发生一次，您可以在response.text上使用以下正则表达式模式

import re

s = '''<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null"};</script>'''
p = re.compile(r'window\._sharedData = (.*);')
print(p.findall(s)[0])

重新导入
s=''window.\u sharedData={“配置”：{“csrf_令牌”：“SSQRJ6C8TFN1HWOILWMPQONT2BAPTNU”，“查看器”：null”}；''
p=re.compile（r'window\.\u sharedData=（.*）；）
印刷品（p.findall[0]）

假设以；结束，并且仅在您可以在response.text上使用以下正则表达式模式时发生

import re

s = '''<script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null"};</script>'''
p = re.compile(r'window\._sharedData = (.*);')
print(p.findall(s)[0])

重新导入
s=''window.\u sharedData={“配置”：{“csrf_令牌”：“SSQRJ6C8TFN1HWOILWMPQONT2BAPTNU”，“查看器”：null”}；''
p=re.compile（r'window\.\u sharedData=（.*）；）
印刷品（p.findall[0]）

以下是一种方法：

>>> xxx = '''
... <script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>
... '''

这里有一个方法：

>>> xxx = '''
... <script>window._sharedData = {"config":{"csrf_token":"sSqrj6c8tfN1HwOIlwmpqONT2bAPhtNu","viewer":null etc....</script>
... '''

return JSON.stringify（window.\u sharedData）nice+return JSON.stringify（window.\u sharedData）nice+
