本文介绍了从使用EXCEL进行用户名密码验证及数据管理转向MySQL的过程。通过对比展示了MySQL在数据处理上的优势，并提供了具体的代码实现，包括前端界面设计与后端数据交互。

之前通过 EXCEL读写实现用户名密码校验，新增，修改，工单发起，显示。受到很多局限性影响，还是转回mysql操作便捷些。

不过前端显示不受影响，只是调整 socketserver服务端代码。

代码如下：

import socketserver
import json
import xlrd
import xlwt
from xlutils.copy import copy

class MyServer(socketserver.BaseRequestHandler):
    def handle(self):
        print('conn is:',self.request)
        print('addr is:',self.client_address)
        while True:
            try:
                data = self.request.recv(102400)
                if not data:break
                data = data.decode('utf-8')
                print('收到客户端的消息是：',data,self.client_address)
                js_data = json.loads(data)

                #类型1登录
                if str(js_data['leixing'])=='1':
                    #关联Excel表里 用户名密码 是否存在
                    ws = xlrd.open_workbook('./images/数据存储表.xls').sheet_by_name('用户名密码')
                    crow=ws.nrows
                    for i in range(crow):
                        if ws.cell_value(i, 0) == js_data['ziduan1']:

                            if str(ws.cell_value(i,1))==js_data['ziduan2']:
                                data='{"leixing":"%s","ziduan1":"%s","ziduan2":"%s","ziduan3":"%s","ziduan4":"%s","ziduan5":"%s","ziduan6":"%s" }' %(
                                '类型1',js_data['ziduan1'],js_data['ziduan2'],'用户名密码正确',ws.cell_value(i,2),ws.cell_value(i,3),ws.cell_value(i,4))

                                break
                            elif str(ws.cell_value(i,1))!=js_data['ziduan2']:
                                data = '{"leixing":"%s","ziduan1":"%s","ziduan2":"%s","ziduan3":"%s" }' % (
                            '类型1', js_data['ziduan1'], js_data['ziduan2'], '用户名密码错误')

                                break

                    else:
                        data = '{"leixing":"%s","ziduan1":"%s","ziduan2":"%s","ziduan3":"%s" }' % (
