2.pymongo的简单用法：

# /usr/bin/env python3
import pymongo


class Mymongo(object): def __init__(self, host, port=27017): try: self.conn = pymongo.MongoClient(host=host, port=port) except Exception as e: print("连接失败", e) else: print('连接成功') def add(self, p_dict): res = self.conn.testdb.testcol.insert(p_dict) # insert需要传入字典 if res: print('插入成功') def show(self): res = self.conn.testdb.testcol.find() # find()返回一个可迭代对象 for i in res: print(i) def mod(self, before, after): # 需要传入字典 res = self.conn.testdb.testcol.update(before, after) if res: print("修改成功", res) def rem(self, p_dict): res = self.conn.testdb.testcol.delete_one(p_dict) if res: print('删除成功') if __name__ == "__main__": mymongo = Mymongo('192.168.26.135') mymongo.add({"name": 'Tom'}) mymongo.show() mymongo.mod({"name": 'Tom'}, {"name": 'Jerry'}) mymongo.show() mymongo.rem({"name": 'Jerry'}) mymongo.show()
