代码解释

• https://pvp.qq.com/web201605/js/herolist.json是官方的英雄信息数据，格式如下
• 
• 从中先获取英雄都是有哪些皮肤，并且获取皮肤的名称
• 根据英雄的ename获取英雄的唯一标识符，进一步获取皮肤的图片地址

hero_skin_url = 'http://game.gtimg.cn/images/yxzj/img201606/skin/hero-info/' + str(
                       hero_num) + '/' + str(hero_num) + '-bigskin-' + str(hero_skin_num + 1) + '.jpg'
