雪球网爬取数据并存入数据库

创建数据库连接

from urllib import request
import json
import pymysql

class mysql_connect(object):
    # 初始化的构造函数
    def __init__(self):
        self.db = pymysql.connect(host='127.0.0.1',user='root',password='yao123',port=3306,database='pachong')
        self.cursor = self.db.cursor()
    # 执行修改操作
    def mysql_do(self,sql):
        self.cursor.execute(sql)
        self.db.commit()

    # 结束函数
    def __del__(self):
        self.cursor.close()
        self.db.close()
