Python爬虫爬取王者荣耀英雄信息并保存到图数据库

爬取信息说明

1. 英雄名称
2. 英雄类型
3. 英雄包含的所有皮肤名称

创建英雄类型节点

王者荣耀官方给出的英雄类型是以下几种：

直接准备好英雄类型词典

hero_type_dict = [
    '战士', '法师', '坦克', '刺客', '射手', '辅助'
]

添加到图数据库中

def create_hero_type_node():
    for hero_type in hero_type_dict:
        cypher = "MERGE (n:HeroType{label: '" + hero_type + "'})"
        graph.run(cypher).data()
    print('创建英雄类型节点成功')

创建英雄信息节点

获取英雄信息

def get_hero_info_list():
    # 英雄的全部信息的url
    hero_info = 'https://pvp.qq.com/web201605/js/herolist.json'
    # 获取英雄的全部信息
    response = requests.get(hero_info)
    # 转为字典格式
    hero_info_dict = json.loads(response.text)
    return hero_info_dict

打印的内容如下：

这里需要注意的是，部分英雄包含两个英雄类别。

保存英雄信息

def create_hero_node():
    hero_info_dict = get_hero_info_list()
    # 1战士 2法师 3坦克 4刺客 5射手 6辅助
    for hero in hero_info_dict:
        # print(hero)
        # print(str(hero.get('cname')) + '===' + str(hero_type[hero.get('hero_type')-1]) + '===' + str(hero.get('skin_name')))
        hero_type_list = [str(hero_type_dict[hero.get('hero_type') - 1])]
        if '|' in str(hero.get('skin_name')):
            skin_name_list = hero.get('skin_name').split('|')
        else:
            skin_name_list = [hero.get('skin_name')]
        if 'hero_type2' in str(hero):
            hero_type_list.append(str(hero_type_dict[hero.get('hero_type2') - 1]))
        # 创建英雄信息节点
        hero_cypher = "MERGE (n:Hero{label: '" + str(hero.get('cname')) + "'})"
        graph.run(hero_cypher).data()
        # 创建英雄->类型关系
        for hero_type in hero_type_list:
            cypher_rel = "MATCH(h:Hero{label:'" + str(
                hero.get('cname')) + "'}),(t:HeroType{label:'" + hero_type + "'}) MERGE (h)-[r:类型]->(t) RETURN h,r,t"
            graph.run(cypher_rel).data()

        for skin_name in skin_name_list:
            # 创建英雄皮肤节点
            cypher = "MERGE (n:Skin{label:'" + skin_name + "'})"
            graph.run(cypher).data()
            # 创建英雄->皮肤关系
            cypher_rel = "MATCH(h:Hero{label:'" + str(
                hero.get('cname')) + "'}),(s:Skin{label:'" + skin_name + "'}) MERGE (h)-[r:皮肤]->(s) RETURN h,r,s"
            graph.run(cypher_rel).data()
        print(str(hero.get('cname')) + '===' + str(hero_type_list) + '===' + str(skin_name_list))
