python3爬虫之设计签名小程序-创新互联

本文实例为大家分享了python3设计签名小程序的具体代码，供大家参考，具体内容如下

首先，上一下要做的效果图：

先是这样一个丑陋的界面（我尽力了的真的！）

然后随便输入名字

然后点击按钮会显示出对应的个性签名:

这个是怎么实现的呢？

其实这个是将一个签名网站http://www.uustv.com/的内容爬下来显示了而已：

源代码如下：

from tkinter import * 
import requests 
from tkinter import messagebox 
import re 
from PIL import Image,ImageTk 
def download(): 
  startUrl = 'http://www.uustv.com/' 
  name = entry.get() 
  if not name: 
    messagebox.showinfo('提示','请输入名字！') 
  else: 
    data = { 
      'word':name, 
      'sizes':'60', 
      'fonts':'jfcs.ttf', 
      'fontcolor':'#000000' 
    } 
 
    result = requests.post(startUrl,data = data) 
    result.encoding = 'utf-8' 
 
    req = '

' 
    imgUrl = startUrl+(re.findall(req,result.text)[0]) 
    response = requests.get(imgUrl).content 
    with open('{}.gif'.format(name),'wb') as f: 
      f.write(response) 
    #im = Image.open('{}.gif'.format(name)) 
    #im.show() 
    bm = ImageTk.PhotoImage(file = 'E:\py\{}.gif'.format(name)) 
    label2 = Label(root, image = bm) 
    label2.bm = bm 
    label2.grid(row = 2,columnspan = 2) 
 
 
root = Tk() 
root.title('GUI') 
root.geometry('600x300') 
root.geometry('+500+200') 
label = Label(root,text = '签名',font = ('华文行楷',20)) 
label.grid(row=0,column = 0) 
entry = Entry(root,font = ('微软雅黑',20)) 
entry.grid(row = 0,column = 1) 
 
 
Button(root,text = '设计签名',font = ('微软雅黑',20),command = download).grid(row = 1,column = 0) 
 
root.mainloop()
