首先引用tkinter和pymysql库;
import tkinter import pymysql
构造一个格式化时间戳的类
#遇到日期特殊处理
class ComplexEncoder(json.JSONEncoder):
def default(self,obj):
if isinstance(obj,datetime):
return obj.strftime('%Y-%m-%d %H:%M:%S')
elif isinstance(obj,date):
return obj.strftime('%Y-%m-%d')
else:
return json.JSONEncoder.default(self,obj)
定义一个函数，实现sql查询的功能，使用entry和combobox获取用户的输入，使用open函数将查询结果导出并存储到D盘；
#定义查询函数
def interface_table_cx_sql():
try:
db = pymysql.connect(host=ip_down_menu.get(),port=int(port_down_menu.get()),user=user_down_menu.get(),password=pw_down_menu.get(),database=db_down_menu.get(), charset='utf8' )
tkinter.messagebox.showinfo('消息框', '数据库连接成功', parent=win)
except:
tkinter.messagebox.showerror('消息框', 'error 数据库连接失败', parent=win)
cursor = db.cursor() #创建一个游标
sql = "select * from " + interface_table_down_menu.get()
try:
# 执行SQL语句
cursor.execute(sql)
results = cursor.fetchall()
cols = cursor.description
data = format_data(results,cols)
cursor.close()
db.close()
data_json=json.dumps(data,cls=ComplexEncoder,indent=1,ensure_ascii=False)
with open('D:/接口库全表查询结果.txt','w') as file:
file.write(data_json)
tkinter.messagebox.showinfo('消息框', '数据已导入D盘 接口库全表查询结果.txt', parent=win)
except:
tkinter.messagebox.showerror('消息框', '错误！！请检查输入信息', parent=win)
定义一个format_data函数将导出的数据格式化为json格式;
def format_data(results,cols):
keys = []
for column in cols:
keys.append(column[0])
key_number = len(keys)
json_data = []
for row in results:
item = dict()
for q in range(key_number):
item[keys[q]] = row[q]
json_data.append(item)
return json_data
以下为主程序:
win = tkinter.Tk()
win.title(test')
# 设置窗口大小
winWidth = 800
winHeight = 600
# 获取屏幕分辨率
screenWidth = win.winfo_screenwidth()
screenHeight = win.winfo_screenheight()
x = int((screenWidth - winWidth) / 2)
y = int((screenHeight - winHeight) / 2)
# 设置窗口初始位置在屏幕居中
win.geometry("800x600")
# 设置窗口图标
win.iconbitmap("D:/ztshouhou for mysql/image/34.ico")
#p1 = PhotoImage(file = 'D:/project/34.jpg')
#win.iconphoto(False, '34.jpg')
# 设置窗口宽高固定
win.resizable(0, 0)
#创建一个菜单项，类似于导航栏
menubar = Menu(win)
#提示1
tishi1 = Label(win,text = '数据库IP和端口号',font = 16)
tishi1.grid(row=0)
