我有一个文本字符串/脚本，我从网页中取出。我想清理/结构的文本字符串/脚本，这样我只能得到JSON出来。但它很长，我失去了找到JSON的开始和结束的文本。有没有人帮助我或建议一个在线网站，可以帮助找到JSON的开始和结束的文本。多谢

您可以使用RegEx从字符串中获取json。
我使用了这个模式:{(?:[^{}]*{[^{]*})*[^{}]*}
上面的正则表达式只检查一层深度的Json。
代码:
import re
import json
input_data = """window.__NUXT__=funct ... A","100553115",void 0)"""
def json_validate(input_str):
founds = re.findall(r"{(?:[^{}]*{[^{]*})*[^{}]*}", input_str)
valid_jsons = []
for x in founds:
try:
valid_jsons.append(json.loads(x))
except json.JSONDecodeError:
continue
return valid_jsons
getting_jsons = json_validate(input_data)
for one_json in getting_jsons:
print(one_json)
print(len(getting_jsons))
它可以在你的字符串中找到几个(32)个有效的json:
>>> python3 test.py
{'features': [{'code': 'text-TvMemory', 'label': 'Tekst TV hukommelse', 'value': '1000'}], 'label': 'Tekst TV hukommelse'}

我找到了另一个解决方案，从完全不同的角度来解决这个问题:https://stackoverflow.com/a/54235803/11502612
我已经从上面的答案测试了代码，我得到了相同的输出。这意味着结果是正确的(可能)。这样做不是更容易吗?
import json
data = json.dumps(your_string)
然后遍历它以查找值。或者，您可以使用
查找值位置。find("{")
不知道这是不是你想要的，但我想它可能会激发一个想法/替代视图
