使用 Python 提取 JSON 字符串中的 URL 使用 re.match() 或 split()

Question

使用我的 Python 代码，我提取了 JSON 文件的特殊部分（列表中的列表或字典的一部分）：

import json
import urllib

f = open('json-test-file-for-insta-url-snippet.json')
data = json.load(f)

print(json.dumps(data["event"]["attachments"][0]["text"]))

我得到了这个结果：

"\u201cUNLIMITED LIVE\u201d world tour moved to 2021!\nDue to the Covid-19 pandemic and the subsequent regulations and concert restrictions, the world tour, originally planned for the autumn of 2020, could not take place. \n\"\u201eI was very much looking forward to our tour in autumn 2020 all over the world, so I\u2019m deeply sorry that these concerts had to be rescheduled due to the Covid-19 pandemic. I\u2019m very happy that we have already found new dates for our tour in autumn 2021, because I cannot wait to return to get back on stage and to play for you guys.

现在我想最后提取 Insta-URL - 我如何在 Python 中做到这一点？ 只能使用正则表达式还是有更聪明的方法？ 我在 Stackoverflow 中读了很多，但对我没有任何作用。 请帮忙！
