这里我们首先新建了一个RequestCookieJar对象,然后将复制下来的cookies利用split() 方法分剖,接着利用 set()方法设置好每个Cookie的key和value,然后通过调用 requests的get()方 法并传递给cookies参数即可。 当然,由于知乎本身的限制, headers参数也不能少,只不过不需要在原来的 headers 参数里面设置 cookie 字段了。
如果HTTP请求返回了不成功的状态码,Response.raise_for_status()将引发一个HTTPError异常。 如果请求超时,将引发一个Timeout异常。 如果请求超出了配置的最大重定向次数,将引发TooManyRedirects异常。 Requests显式引发的所有异常都继承自requests.exceptions.RequestException。 参考链接 ...
