:params retry_num 重试次数
:return response对象/False
如果options中有定义了headers参数,则使用定义的;否则使用init中初始化的headers
下面这行列表推导式作用在于：
添加referer时,referer需要是上一个页面的url,比如:画师/作品页面的url时,则可以自定义请求头
demo如下:
demo_headers = headers.copy()
demo_headers['referer'] = 'www.example.com'
options ={
"method":"get",
"url":"origin_url",
"headers":demo_headers
}
baseRequest(options=options)
这样baseRequest中使用的headers则是定制化的headers,而非init中初始化的默认headers了

# log_str(options["url"])

options["headers"] if "headers" in options.keys() else self.headers
][0]
