### 一、爬蟲遇到的問題 1. 需要下載付費部分，因此需要登錄。否則無法獲取鏈接。 2. 鏈接`token`有時限，需要即時下載，否則會過期。 `https://vb1.ating.info/fiction/wuxia/feitian/3euezgrd.mp3?token=oS8IWpFYAUnP1SZKF6GjFg**_6J_cScZL-7S3cfeRCJbWVt6GkPEtL-0_&e=1587737779216&t=2&res=970411484&sign=76e85feabf8878bf935a64e41344b7c7`  3. 文件名具有特殊符號，無法保存。 ### 二、爬蟲實現 1. 用`requests`的模塊保持鏈接`.session()`。 ```python LoginUrl = 'https://m.lrts.me/ajax/logon' conn = requests.session() PostData = {"account":account,"pwd":ba_password} rep = conn.post(LoginUrl, data=PostData) repJson = json.loads(rep.text) msg = repJson['msg'] if msg =='賬號或密碼錯誤': print('帳號或密碼錯誤，僅下載免費部分') else: print('登錄成功，下載該帳號免費部分及購買部分') ``` 2. 即時調用下載軟件下載。 ```python IdmPath = 'C:\Program Files (x86)\Internet Download Manager\IDMan.exe' def IdmDownLoad(DownloadUrl, Mp3Name): call([IdmPath, '/d',DownloadUrl,'/p',FilePath,'/f',Mp3Name,'/n']) ``` 3. replace**替換**所有特殊字符。 def ChangeFileName(filename): ```python def ChangeFileName(filename): filename = filename.replace('\\','') filename = filename.replace('/','') filename = filename.replace('：','') filename = filename.replace('*','') filename = filename.replace('“','') filename = filename.replace('”','') filename = filename.replace('<','') filename = filename.replace('>','') filename = filename.replace('|','') filename = filename.replace('?','？') filename = filename.replace('（','(') filename = filename.replace(chr(65279),'') # UTF-8+BOM filename = filename.split('(')[0] return filename ``` ### 三、爬蟲實現。 `https://github.com/yoval/lrts`（需設定好time.sleep）
