微信請掃描下方二維碼

代碼僅供學習交流，請勿用於非法用途

一、準備數據庫（sqlserver）

create table  notify_list(
    id INT NOT NULL identity(1,1),
    openid VARCHAR(40) not null,
    templateid VARCHAR(50) not null,
    toUrl VARCHAR(200) default null,
    mpappid VARCHAR(60) default null,
    mppath VARCHAR(200) default null,
    sendstatus VARCHAR(20) default null,
    sendres VARCHAR(20) default null,
    flag VARCHAR(1) default null,
    f1 varchar(100) default null,
    f2 varchar(100) default null,
    f3 varchar(100) default null,
    f4 varchar(100) default null,
    f5 varchar(100) default null,
    f6 varchar(100) default null,
    f7 varchar(100) default null,
    f8 varchar(100) default null,
    f9 varchar(100) default null,
    f10 varchar(100) default null,
    f11 varchar(100) default null,
    f12 varchar(100) default null,
    PRIMARY KEY(id)
)

二、代碼實現

dao.py

# -*- coding:utf-8 -*-
import pymssql
import configparser
import os

cf = configparser.ConfigParser()
try:
    cf.read(os.getcwd() + "/conf.ini", encoding="utf-8-sig")
except Exception as e:
    print("程序目錄下不存在conf.ini配置文件~")
    exit(0)


def getConf(sec, key):
    try:
        return cf.get(sec, key)
    except Exception as e:
        print(e)
        print("未得到以下配置：" + sec + " - " + key)
        exit(0)

#####################################################
# 配置段

user = getConf("Mysql-Database", "user")
password = getConf("Mysql-Database", "password")
port = getConf("Mysql-Database", "port")
database = getConf("Mysql-Database", "database")


def execSql(sql):
    try:
        conn = pymssql.connect(host=host, user=user, password=password, port=port, database=database)
        cur = conn.cursor()
        cur.execute(sql)
        conn.commit()
        return True
    except Exception as e:
        pass
    return False


def querySql(sql):
    try:
        conn = pymssql.connect(host=host, user=user, password=password, port=port, database=database)
        cur = conn.cursor()
        cur.execute(sql)
        return cur.fetchall()
    except Exception as e:
        pass
    return
