连接数据库

　　连接数据库进行增删改查

import pymysql

# 配置数据库相关信息
dbinfo = {
    "host": "127.0.0.1",
    "user": "root",
    "password": "123456",
    "port": 8080
}

class DbConnect(object):
    def __init__(self, db_cof, database=""):
        # 打开数据库连接
        self.db = pymysql.connect(database=database, cursorclass=pymysql.cursors.DictCursor, **db_cof)
        # 使用cursor()方法获取操作游标
        self.cursor = self.db.cursor()
        print("连接成功")

    def select(self, sql):
        # sql查询语句
        # sql = 'select * from table where name="张三"'
        self.cursor.execute(sql)
        results = self.cursor.fetchall()
        print("查询成功")
        return results

    def execute(self, sql):
        # sql删除、提交、修改语句
        print("删除成功")
        try:
            self.cursor.execute(sql)  # 执行sql语句
            self.db.commit()  # 提交修改
        except:
            # 发生错误时回滚
            self.db.rollback()

    def close(self):
        # 关闭连接
        self.db.close()

if __name__ == "__main__":
    db = DbConnect(dbinfo, database='info')
    sql = 'select * from info where id=1;'
    res = db.select(sql)
    print(res)

    sql1 = 'delete from info where id =2;'
    res1 = db.execute(sql)
    print(res1)

　　测试结果校验数据库状态

from utils.connect_mysql import DbConnect, dbinfo

def get_db_info(user_id,key='id'):
    db = DbConnect(dbinfo, database='info')
    sql = 'select * from info where id=%s;' % user_id
    res = db.select(sql)
    print(res)
    if len(res) == 0:
        result = '空'
    else:
        result = res[0][key]
    return result
if __name__ == "__main__":
    r = get_db_info(user_id=1)
    print(r)

　　　　update_info.py

config:
    name: 修改用户信息用例
    base_url: http://127.0.0.1:8080
    variables:
        user_id: 1
        username: "zhangsan"
        usertel: 13333333333
        usersex: "m"
        birthaddress: "羊村"
        birthday: 2000-01-01
        schoolname: "蓝翔技校"
