在python中从文本文件中提取所有缩略图URL？

我有一个充满不同URL的文本文件，例如Web URL、图像URL和其他单词，我只想提取python语言中的缩略图URL

文本文件数据看起来像

 {\"pageLoadPingUrl\": \"https:\\/\\/www.bingapis.com\\/api\\/ping\\/pageload?IG=70DEC9E74D99437586013A62D392EB6E&CID=1923A11AB20A622F3EF3AB0AB33B63A7&Type=Event.CPT&DATA=0\"}, \"readLink\": \"https:\\/\\/api.cognitive.microsoft.com\\/api\\/v5\\/images\\/search?q=football\", \"webSearchUrl\": \"https:\\/\\/www.bing.com\\/cr?IG=70DEC9E74D99437586013A62D392EB6E&CID=1923A11AB20A622F3EF3AB0AB33B63A7&rd=1&h=DguPUeDUYz2pg6YQ4vb7fHcxaHr5_zxsw_96_Rf4uJY&v=1&r=https%3a%2f%2fwww.bing.com%2fimages%2fsearch%3fq%3dfootball%26FORM%3dOIIARP&p=DevEx,5226.1\", \"totalEstimatedMatches\": 984, \"value\": [{\"name\": \"... Sallis, \\\"Moving the Movement Football\\\" | Counter-Currents Publishing\", \"webSearchUrl\": \"https:\\/\\/www.bing.com\\/cr?IG=70DEC9E74D99437586013A62D392EB6E&CID=1923A11AB20A622F3EF3AB0AB33B63A7&rd=1&h=DxYxhRhR_W5Ww0BYlGqMNvRtnSpmF6AKMXkf6NmsymM&v=1&r=https%3a%2f%2fwww.bing.com%2fimages%2fsearch%3fview%3ddetailv2%26FORM%3dOIIRPO%26q%3dfootball%26id%3dDCE3B4704C97EC1064A12E7D693389AD809DA302%26simid%3d608014267730954997&p=DevEx,5006.1\", \"thumbnailUrl\": \"https:\\/\\/tse3.mm.bing.net\\/th?id=OIP.Mf0c3eb142508ab40b0a7680f777f452fo0&pid=Api\"

预期产量为

https:\\/\\/tse3.mm.bing.net\\/th?id=OIP.Mf0c3eb142508ab40b0a7680f777f452fo0&pid=Api
https:\\/\\/tse3.mm.bing.net\\/th?id=OIP.Mf0c3eb142508ab40b0a73432f777f452fo0&pid=Api

这是我所做的代码

def get_net_target(page):    start_link=page.find("thumbnailUrl\"" )
 start_quote=page.find('"',start_link) 
 end_quote=page.find('"',start_quote+1)
 url=page[start_quote+1:end_quote]
 print url

您确定它不是包含json的文本文件吗？。。。你尝试了什么再次看到问题我编辑了代码文本文件数据看起来仍然非常像json。是的，它是json对象我制作了一个文件并将该对象保存在文本文件中
