跟潭州學院的強子老師學習網絡爬蟲---爬取全書網

真是太白了，python之路還有很長，今天我從這裏開始，留做本身備忘。2018-04-05

花了一個下午學習個爬小說的，總的來講是由於本身沒什麼基礎，哪裏不會補哪裏，磕磕絆絆的，總算是能運行，先把代碼放這裏，之後請教高手幫助解決一下。

        print('問題緣由是%s'%str(reason))

沒解決的問題：

一、問題緣由：('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

      本身分析：多是由於反覆訪問服務器，服務器認爲我是機器人，被反爬了，文件頭也有換，爬個幾本小說就會出錯。

      解決結果：沒有解決。
