用tkinter制作签名设计窗口

效果如下：

from tkinter import *
from tkinter import messagebox
import requests
import re
from PIL import Image,ImageTk

def show(root,enter):
    start_url = 'http://www.uustv.com/'
    name = enter.get()
    if not name:
        messagebox.showinfo('警告：','请输入用户名')
    else:
        data = {
            'word': name,
            'sizes': 60,
            'fonts': 'jfcs.ttf',
            'fontcolor': '#000000'
        }
        result = requests.post(start_url,data=data)#给服务器发送post
        result.encoding = 'utf-8'
        html = result.text
        reg = '<div class="tu">.*?<img src="(.*?)"/>.*?</div>'
        img_path = re.findall(reg,html)
        img_url = start_url + img_path[0]

        response = requests.get(img_url).content
        f = open('{}.gif'.format(name),'wb')
        f.write(response)

        bm = ImageTk.PhotoImage(file='{}.gif'.format(name))
        lable2 = Label(root, image=bm)
        lable2.bm = bm
        lable2.grid(row=2,columnspan=2)

def main():
    root = Tk()#实例化一个对象
    root.title('签名设计')
    root.geometry('600x300')#长600，宽300

    lable =  Label(root,text='签名',font=('华文行楷',20),fg='red')
    lable.grid(row=0,column=0)

    enter = Entry(root,font=('微软雅黑',22),fg='black')
    enter.grid(row=0,column=1)

    button = Button(root,text='设计签名',font=('微软雅黑',22),command=lambda :show(root,enter))
    button.grid(row=1,column=0)

    root.mainloop()

if __name__ == '__main__':
    main()
