python篇—base64码流转成图片保存

import osimport base64from io import BytesIOfrom PIL import Imagefrom faker import Fakerfak = Faker() # 输入为base64格式字符串，输出为PIL格式图片def base64_to_image(base64_str):  # 用 b.show()可以展示    image = base64.b64decode(base64_str, altchars=None, validate=False)    image = BytesIO(image)    image = Image.open(image)    return imageif __name__ == '__main__':    file_path = "/app/yyq/dataset/1putuo_waste_project/important_real_data/log_results"    file_sum = os.listdir(file_path)    # 图片保存路径    save_img = "/app/yyq/dataset/1putuo_waste_project/important_real_data/bs64_img/"    if not os.path.exists(save_img):        os.makedirs(save_img)    for fi in file_sum:        file = open(os.path.join(file_path, fi), "r")        print(fi)        try:            while True:                line = file.readline()                if line:                    img = base64_to_image(eval(line)["pic"])                    # 随机生成时间用于保存图片                    date_ = fi.split("_")[0] + "-" + fak.date(pattern='%H:%M:%S').replace(":", "-")                    img_name = save_img + date_ + ".jpeg"                    img.save(img_name)                    print(eval(line)["processdate"], eval(line)["result"])                else:                    break        except:            pass        finally:            print("{}文件处理完成".fORMat(file))            file.close()

这里分享个比较好玩的，随机生成时间

from faker import Fakerfak = Faker()print('日期：', fak.date(pattern = '%H:%M:%S'))print(type(fak.date(pattern = '%H:%M:%S')))print('年：', fak.year())print('月：',fak.month())print('日：', fak.day_of_month())print('星期：', fak.day_of_week())
