Building a Python GUI Translator with Tkinter and Web Requests

The article introduces a Python project that implements a personal translator with a graphical user interface built on Tkinter. It explains that the program sends translation requests to Youdao's online API by constructing the required parameters, generating a security sign, and handling the JSON response.

Key components include importing necessary modules (tkinter, random, requests, urllib, time, json, hashlib), setting up the main window, and defining two functions: pachong() for performing the HTTP request and parsing the result, and eBtn(event) for handling button clicks, retrieving user input, and displaying the translated text.

The provided source code is presented in a pre block to preserve formatting:

<code>import tkinter
import random
import requests
import request
import urllib
from urllib import request,parse
import time,json,random,hashlib
win = tkinter.Tk()

def pachong():
    try:
        url = "http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"
        data = {}
        u = 'fanyideskweb'
        d = content
        f = str(int(time.time() * 1000) + random.randint(1, 10))
        c = 'rY0D^0\'nM0}g5Mm1z%1G4'
        sign = hashlib.md5((u + d + f + c).encode('utf-8')).hexdigest()
        data['i'] = content  # 需要翻译的内容
        data['from'] = 'AUTO'
        data['to'] = 'AUTO'
        data['smartresult'] = 'dict'
        data['client'] = 'fanyideskweb'
        data['salt'] = f
        data['sign'] = sign
        data['doctype'] = 'json'
        data['version'] = '2.1'
        data['keyfrom'] = 'fanyi.web'
        data['action'] = 'FY_BY_CL1CKBUTTON'
        data['typoResult'] = 'true'
        data = parse.urlencode(data).encode('utf-8')
        req = request.Request(url, data=data)
        response = request.urlopen(req)
        res = response.read().decode('utf-8')
        res = json.loads(res)
        res = res["translateResult"]
        return res[0][0]['tgt']
    except:
        print("cuowu")

def eBtn(event):
    global content
    content = entry_w.get()
    entry_r.config(entry_r,text = content)
    entry_r.delete(0,80)
    entry_r.insert(0,str(pachong()))
    # pachong()

if __name__ == "__main__":
    label_val_q = tkinter.Label(win,width = "80")
    label_val_q.pack(side = "top")
    label_val_q.config(label_val_q,text = "请输入要翻译的文本")
    entry_w = tkinter.Entry(win,width = "80")
    entry_w.pack(side = "top")
    btn = tkinter.Button(win, text="翻译")
    btn.pack(side = "top")
    btn.bind('<Button-1>',eBtn)
    label_val_q = tkinter.Label(win,width = "80")
    label_val_q.pack(side = "top")
    label_val_q.config(label_val_q,text = "翻译为:")
    entry_r = tkinter.Entry(win,width = "80")
    entry_r.pack(side = "top")
    entry_r.bind('<Return>',eBtn)
    win.mainloop()
</code>

Running the script opens a window where users can input text, click the "翻译" button, and see the translated result displayed in a second entry field. The article concludes with a disclaimer that the content is collected from the internet and credits the original author.
