成功解决:python爬虫http.client.RemoteDisconnected: Remote end closed connection without response

参考:Python爬虫:http.client.RemoteDisconnected:Remoteendclosedconnectionwithoutresponse问题解决使用python爬虫中的urllib或者requests库获取数据时出现报错:http.client.RemoteDisconnected:Remoteendclosedconnectionwithoutresponse原因:大多数网站都会对用户请求中的User-Agent进行检测,如果没有在请求头中设置User-Agent,那么就会抛出异常改进方法:在headers中添加:User-Agentimporturllib.r
