2020-07-26调用百度API应用——小小翻译器

  urllib是Python标准库中最常用的python网页访问模块，它可以让用户像访问文本一样读取网页的内容

```

from tkinter import *

from urllib import request

from urllib import parse

import json

import hashlib

def translate_Word(en_str):

    URL = 'http://api.fanyi.baidu.com/api/trans/vip/translate'

    Form_Data = {}      #创建From_Data字典，存储向服务器发送的Data

    Form_Data['from'] = 'en'      #译前---英文

    Form_Data['to'] = 'zh'        #译后---中文

    Form_Data['q'] = en_str

    Form_Data['appid'] = '2015063000000001'    #自己申请的app id

    Form_Data['salt'] = '1435660288'         

    Key = "12345678"                          #平台分配的密钥

    m = Form_Data['appid'] + en_str + Form_Data['salt'] + Key

    m_MD5 = hashlib.md5(m.encode('utf8'))

    Form_Data['sign'] = m_MD5.hexdigest()

    data = parse.urlencode(Form_Data).encode('utf-8') #使用urlencode()方法转换为标准格式

    response = request.urlopen(URL,data)

    html = response.read().decode('utf-8')            #读取信息并解码

    translate_results = json.loads(html)

    print(translate_results)

    translate_results = translate_results['trans_result'][0]['dst']  #找到翻译结果

    print("翻译的结果是：%s" % translate_results)

    return translate_results

def leftClick(event):

    en_str = Entry1.get()

    print(en_str)

    vText = translate_Word(en_str)

    Entry2.config(Entry2,text = vText)

    s.set("")

    Entry2.insert(0,vText)

def leftClick2(event):

    s.set("")

    Entry2.insert(0,"")

if __name__ == "__main__":

    root = Tk()

    root.title("单词翻译器")

    root['width'] = 250;root['height'] = 130

    Label(root,text = '输入要翻译的内容：',width = 15).place(x = 1,y = 1)    #绝对坐标

    Entry1 = Entry(root,width = 20)

    Entry1.place(x = 110,y = 1)

    Label(root,text = '翻译的结果：',width = 18).place(x = 1,y = 20)

    s = StringVar()

    s.set("大家好，这是测试")

    Entry2 = Entry(root,width = 20,textvariable = s)

    Entry2.place(x = 110,y = 20)

    Button1 = Button(root,text = '翻译',width = 8)

    Button1.place(x = 40,y = 80)

    Button2 = Button(root,text = '清空',width = 8)

    Button2.place(x = 110,y = 80)

    Button1.bind("",leftClick)

    Button2.bind("",leftClick2)

    root.mainloop()

```

结果：
