Regex 使用python正则表达式分隔字符串

我试图从Amazon产品页面中获取一些图像，我能够在单个字符串中提取页面中的所有图像，但我对正则表达式的了解不足以将其与其他URL分开

我的目标是获得一个数组/列表，其中包含所有雇佣的图像，例如，这张

这是完整的字符串

所有图像都在“colorImage”细分下

P.when('A').register("ImageBlockATF", function(A){

    var data = {

                'colorImages': { 'initial':

如果您想坚持使用正则表达式解决方案，可以尝试如下匹配：r'\hiRes\：\https.*？\.jpg\'

快速解释：

匹配任何以hiRes:https开头，以.jpg结尾的字符串 使用捕获组获取实际的URL这假设所有URL都以https开头，以.jpg结尾

---

您可以将上面的正则表达式与re.match或re.search一起使用，希望得到您想要的。您应该能够从这里提取匹配组。请参阅id您需要更多详细信息。

也许您的示例中缺少了一些内容，但data是一个字典，您可以直接为图像引用，例如data['colorImages']['initial'][0]['hiRes']。没有要应用正则表达式的字符串。如果我不够清楚，很抱歉。这段代码本身就是一个字符串，我使用XPath//script[contains.，ImageBlockATF]/text从Amazon页面中提取了该代码。这个示例是我从该产品中提取的。很抱歉回答得这么晚，我忙了几天。这很有效！，最终使用了re.findall'\hiRes\：\https.*？\.jpg\'图像。谢谢你的帮助！
