篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Python实现翻译小工具相关的知识，希望对你有一定的参考价值。

一、背景

利用Requests模块获取有道词典web页面的post信息，BeautifulSoup来获取需要的内容，通过tkinter模块生成gui界面。

二、代码

fanyi.py代码如下：

#!/bin/env python
# -*- coding:utf-8 -*-
# _author:kaliarch
import requests
import urllib.parse
import time
import random
import hashlib
import json

class search(object):
    def __init__(self):
        self.url = ‘http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule‘

    def getData(self,search_name):
        # salt =i = "" + ((new Date).getTime() + parseInt(10 * Math.random(), 10)
        salt = ((time.time() * 1000) + random.randint(1,10))
        # sign = n.md5("fanyideskweb" + t + i + "ebSeFb%=XZ%T[KZ)c(sy!")
        sign_text = "fanyideskweb" + search_name + str(salt) + "ebSeFb%=XZ%T[KZ)c(sy!"
        sign = hashlib.md5((sign_text.encode(‘utf-8‘))).hexdigest()
        paydata = {
            ‘i‘: search_name,
            ‘from‘: ‘AUTO‘,
            ‘to‘: ‘AUTO‘,
            ‘smartresult‘: ‘dict‘,
            ‘client‘: ‘fanyideskweb‘,
            ‘salt‘: salt,
            ‘sign‘: sign,
            ‘doctype‘: ‘json‘,
            ‘version‘: ‘2.1‘,
            ‘keyfrom‘: ‘fanyi.web‘,
            ‘action‘: ‘FY_BY_CLICKBUTTION‘,
            ‘typoResult‘: ‘false‘
        }
        return paydata

    def getHeader(self):
        header = {
            ‘Host‘: ‘fanyi.youdao.com‘,
            ‘Referer‘: ‘http://fanyi.youdao.com/‘,
            ‘Content-Type‘: ‘application/x-www-form-urlencoded; charset=UTF-8‘,
            ‘User-Agent‘: ‘Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/55.0.2883.87 Safari/537.36‘,
            ‘Cookie‘: ‘OUTFOX_SEARCH_USER_ID=-846616837@1.80.219.201; OUTFOX_SEARCH_USER_ID_NCOO=129549097.60835753; UM_distinctid=15ff309f18ddc-094cb5494ad815-5d4e211f-1fa400-15ff309f18e449; _ga=GA1.2.184261795.1517119351; __guid=204659719.2556877880764680700.1518435624954.942; JSESSIONID=aaa3A5BLhtTrh4TPX_mgw; monitor_count=2; ___rl__test__cookies=1518488731567‘
        }
        return header

    def getRequest(self,paydata,header):
        _data = urllib.parse.urlencode(paydata).encode(‘utf-8‘)
        _header = header
        response = requests.post(self.url,data=_data,headers=_header)
        return response.text

    def getResult(self,response):
        result_text = json.loads(response)
        #src = result_text[‘translateResult‘][0][0][‘src‘]
        tgt = result_text[‘translateResult‘][0][0][‘tgt‘]
        return tgt

    def main(self,search_name):
        app = search()
        paydata = app.getData(search_name)
        header = app.getHeader()
        response = app.getRequest(paydata, header)
        tgt = app.getResult(response)
        return tgt

windows.py代码如下：

#!/bin/env python
# -*- coding:utf-8 -*-
# _author:kaliarch

import tkinter as tk
from fanyi import search

class application:
    def __init__(self):
        self.windows = tk.Tk()
        self.windows.title("翻译小工具")
        self.windows.geometry("280x350+700+300")

        #提交按钮
        self.submit_btn = tk.Button(self.windows, text="查询",command=self.submit)
        self.submit_btn.place(x=220, y=10, width=50, height=25)

        # 定义输入框
        self.entry = tk.Entry(self.windows)
        self.entry.place(x=10, y=10, width=200, height=40)

        #输出内容
        self.result_text = tk.Text(self.windows, background="#ccc")
        self.result_text.place(x=10, y=90, width=260, height=245)

        # 翻译结果标题
        self.title_label = tk.Label(self.windows, text="翻译结果：")
        self.title_label.place(x=10, y=65)
        self.search_result = search()

    def submit(self):
        #1.获取用户输入
        context = self.entry.get()

        #2.利用有道翻译
        result = self.search_result.main(context)
        #3.输出
        self.result_text.delete(1.0,tk.END)
        self.result_text.insert(tk.END,result)

    def run(self):
        self.windows.mainloop()

if __name__ == ‘__main__‘:
    winapp = application()
    winapp.run()

setup.py代码如下：

# -*- coding:utf-8 -*-
# _author:kaliarch

import sys
from cx_Freeze import setup,Executable

import os

os.environ[‘TCL_LIBRARY‘] = r"C:Program FilesPython36	cl	cl8.6"
os.environ[‘TK_LIBRARY‘] = r"C:Program FilesPython36	cl	k8.6"

include_files = [
    r"C:Program FilesPython36DLLs	cl86t.dll",
    r"C:Program FilesPython36DLLs	k86t.dll",
]

build_exe_options = {
    "packages":["os","tkinter","requests","idna"],
    "include_files":include_files
}

base = None

if sys.platform == "win32":
    base = "Win32GUI"

setup(name = "translate_tool",
    version = "0.1",
    description = "fanyitools!",
    options = {"build_exe":build_exe_options},
    executables = {Executable("windows.py",base=base,icon=‘img.ico‘)}
    )

三、效果展示

运行windows.py，输入想要翻译的内容，点击翻译即可查看翻译结果

可以利用cx_Freeze打包成windows的mis安装小程序，方便使用

切换到项目目录下执行python setup.py bdist_msi
待执行完毕，可以项目文件下生成两个文件夹dist中为msi安装文件，在其他windows服务器安装后就为build下的文件内容，在build下的exe.win-amd64-3.6下的windows.exe 就可打开小工具

进行安装测试

安装完成后可以运行安装目录下的windows.exe打开小工具
