import urllib.request
import urllib.parse
import json
from tkinter import *


x, y = 0, 0
tk = Tk()


tk.title("网易有道翻译")
tk.geometry("840x400")
tk.maxsize(840, 600)
Label(tk, text="有道翻译", font=("微软雅黑", 16)).place(x=100, y=80, anchor="w")

left = Entry(tk)
left.place(x=200, y=160, anchor="n")
var = left.get()

right = Entry(tk)
right.place(x=600, y=160, anchor="n")




url = "http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"
data = {}
data['type'] = " AUTO'"
data['i'] =var
data['doctype'] = 'json'
data[' xmlVersion'] = '1.6'
data['keyfrom'] = " fanyi.web"
data['ue'] = 'UTF-8'
data['typoResult'] = ' true'

data = urllib.parse.urlencode(data).encode("utf-8")

reponse = urllib.request.urlopen(url, data)
html = reponse.read().decode("utf-8")

target = json.loads(html)
fanyi = target["translateResult"][0][0]["tgt"]


right.insert(0,fanyi)
mainloop()


错误异常
Traceback (most recent call last):
  File "D:/python/untitled/youdao.py", line 41, in <module>
    target = json.loads(html)
    raise JSONDecodeError("Expecting value", s, err.value) from None

代码中的youdao_translate 模块拷贝代码
使用自动下载代理，爬取有道词典
保存为youdao_translate.py, 和下面的文件放在同一个目录下，proxypool.py也放在同一个目录下。

1. import youdao_translate as yd
   
2. from tkinter import *
   
3. 
   
4. root = Tk()
   
5. 
   
6. root.title("网易有道翻译")
   
7. root.geometry("840x400")
   
8. root.maxsize(840, 600)
   
9. 
   
10. name = Label(root, text="有道翻译", font=("微软雅黑", 16))
    
11. name.place(x=100, y=80, anchor="w")
    
12. 
    
13. left = Entry(root)
    
14. left.place(x=200, y=160, anchor="n")
    
15. 
    
16. right = Entry(root)
    
17. right.place(x=600, y=160, anchor="n")
    
18. 
    
19. def translate():
    
20.     content = left.get()
    
21.     trans = yd.YoudaoTran()
    
22.     result = trans.translate(content)   
    
23.     right.insert(0,result)   
    
24. 
    
25. btn_translate = Button(text='翻译', command=translate)
    
26. btn_translate.place(x=600, y=200, anchor="w")
    
27. 
    
28. mainloop()
