### 一、爬虫遇到的问题 1. 需要下载付费部分，因此需要登录。否则无法获取链接。 2. 链接`token`有时限，需要即时下载，否则会过期。 `https://vb1.ating.info/fiction/wuxia/feitian/3euezgrd.mp3?token=oS8IWpFYAUnP1SZKF6GjFg**_6J_cScZL-7S3cfeRCJbWVt6GkPEtL-0_&e=1587737779216&t=2&res=970411484&sign=76e85feabf8878bf935a64e41344b7c7`  3. 文件名具有特殊符号，无法保存。 ### 二、爬虫实现 1. 用`requests`的模块保持链接`.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 =='账号或密码错误': print('帐号或密码错误，仅下载免费部分') else: print('登录成功，下载该帐号免费部分及购买部分') ``` 2. 即时调用下载软件下载。 ```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**替换**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、爬虫实现。 `https://github.com/yoval/lrts`（需设定好time.sleep）
