requests_html模块在HTML对象的基础上使用render()方法来重新加载js页面,它有以下几个参数: def render(self, retries: int = 8, script: str = None, wait: float = 0.2, scrolldown=False, sleep: int = 0, reload: bool = True, timeout: Union[float, int] = 8.0, keep_page: bool = False):...

同样是简短的几行代码,和之前的破解js相比,真是大大提升了我们的爬虫效率,这里主要是用了render函数,我们来一起看一下它的源代码 defrender(self,retries:int=8,script:str=None,wait:float=0.2,scrolldown=False,sleep:int=0,reload:bool=True,timeout:Union[float,int]=8.0,keep_page:bool=False):""" re...

render(retries: int = 8, script: str = None, wait: float = 0.2, scrolldown=False, sleep: int = 0, reload: bool = True, timeout: Union[float, int] = 8.0, keep_page: bool = False) 执行JavaScript,在Chromium里重新加载响应,并用最新获取到的HTML替换掉原来的HTML。
