如何在Python中使用Regex从一行JSON文本文件中提取URL？

我一直在努力解决这个问题，但我似乎只能将一个 URL 导出到输出文件。

我目前使用的代码是...

import glob, re

with open('urls.txt', 'a') as output:
    for file in glob.glob('json.txt'):
        with open(file, 'r') as f:
            for line in f.readlines():
                pattern = r"(http|ftp|https):\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])"
                find = re.findall(pattern, line)
                if find:
                    try:
                        output.write(str(find[0]))
                    except UnicodeEncodeError:
                        pass

我已经测试了Regex代码，它能够匹配所有URL，只是不能将它们全部输出到文件中。

我一直试图提取URL的文件包含以下内容......
