class Crawler:

    @staticmethod
    def get_images_url(word: str, num: int, original: bool = True,
                       timeout: int = __CONCURRENT_TIMEOUT) -> (bool, bool, list):

参数

• word:str:搜索关键词
• num:int:搜索数量
• original:bool, optional:是否下载原图，默认为False
• timeout:int, optional:请求timeout，默认为60s

返回

• net:bool:网络连接状态
• num:bool:图片数量是否足够
• urls:list:获取的urls，每项为一个dict，

class Crawler:

    @staticmethod
    def download_images(urls: list, rule: tuple = ('.png', '.jpg'),
                        path: str = 'download', timeout: int = __CONCURRENT_TIMEOUT,
                        concurrent: int = __CONCURRENT_NUM, command: bool = True) -> (int, int):

参数

• urls: list: 需要爬的图片列表，格式与get_images_url返回的相同
• rule: tuple, optional: 允许下载的格式，默认为('.png', '.jpg')
• path: str, optional: 图片下载的路径，默认为'download'
• timeout: int, optional: 请求 timeout, 默认为60(s)
• concurrent: int, optional: 并行下载的数量，默认为100
• command: bool, optional: 是否在控制台显示进度条，默认为True

返回

• success: int: 下载成功的数量
• failed: int: 下载失败的数量
