下载MongoDB数据库

首先，需要下载MongoDB数据库，下载的话比较简单，直接去官网找到想要的版本下载即可，具体安装过程可以看这里。

pycharm下载pymongo库

pip install pymongo

然后在在python程序中我们可以这样连接MongoDB数据库：

import pymongo

#指定数据库与表
# client = pymongo.MongoClient(host='127.0.0.1', port=27017)
# connect = client['table']

client = pymongo.MongoClient(host='127.0.0.1', port=27017)
connect = client['table']['table_info']
# 插入一条数据
info = {'name': 'python', 'age': 18}
result = connect.insert_one(info)
print(result)
# 查询数据
res = connect.find()
print(res)

# 插入多条数据
info_1 = {'name': 'python', 'age': 18}
info_2 = {'name': 'spider', 'age': 18}
result = connect.insert_many([info_1, info_2])
print(result)
res = connect.find()
print(list(res))

了解pymongo的常用语法后，我们来练习爬取爱奇艺的视频数据信息：标题、播放地址、简介并存入MongoDB数据库。

    def insert_in_mongo(self):

        connect.insert_many(insertLists)
        # time.sleep(1)
        print('插入完成！')

    def main(self):
        self.insert_in_mongo()


if __name__ == '__main__':
    aiqiyi = AiQiYi()
    aiqiyi.main()

最终结果如图：
