Question

我不知道我做错了什么。我试图解析JavaScript中的特定内容。在

这是“s”的输出（对于下面的代码）：

这就是我要执行的代码。在

^{pr2}$

运行此程序时，系统将提示我以下错误：

json.decoder.JSONDecodeError: Extra data: line 1 column 12215 (char 12214)

我完全迷路了，不知道哪里出了问题。所有的帮助都是感激和感谢所有那些提前作出贡献的人！在

Answer 1

我认为您可以通过将regex添加到肯定的lookahead (?=;</script>):来更新正则表达式，使其与末尾不带分号的json相匹配

^{}

在给定示例的第一行中，如果没有[3]，代码可能会如下所示：

s = str(soup.find_all("script", type="text/javascript"))
m = re.search(r"(?<=window\._sharedData = )(?P<json>.*)(?=;</script>)", s)
if m:
    data = json.loads(m.group('json'))
    for i in data['entry_data']["ProfilePage"]:
        for j in i['graphql']['user']['edge_owner_to_timeline_media']['edges']:
            print(j['node']["id"])

Answer 2

这里没有足够的调试，您为s提供的不包括</script>，因此当我在本地运行模式时，它永远不会匹配，但是当我附加它时，它似乎工作正常

从错误中可以清楚地看出，m.group('json')的内容实际上不是一个有效的JSON字符串，因此我怀疑您需要处理正则表达式。尝试打印出m.group('json')的值（在尝试解析它之前），并将其输入到一个json验证器中，例如https://jsonlint.com/，它将指导您找到错误所在，也许该行以需要去掉的;结尾，或者出现其他问题
