## Config
Config will be generated automatically.
```ini
[CUSTOM]
uri_keywords = qian,dai,cf,wd,jin
text_keywords = 网贷
ad_filter = https://ss3.baidu.com/*,https://ss2.bdstatic.com/*
```

## ATTENTION!!!
调用is_finance(),判断链接是否是金融链接时,必须传入 href 超链接指向的target地址,且格式如同`{scheme}://{domain}/{path}`,其中`path`可以省略。
