免费翻译API破解(简易翻译工具)

思路：选取有道翻译，用fiddler抓取接口请求信息，提取相关请求参数，破解加密部分。

主要请求数据：

i  ：翻译文本

ts：时间戳

salt：ts +随机数

sign：加密信息，经过抓取信息，发现sign = md5（固定字符串1+ i + salt +固定字符串2）  固定字符串请百度方法。

数据经过urlencode后请求，获取到json数据后取出翻译文本。

下面直接上代码：

#coding = utf-8
import requests
from urllib import parse
from hashlib import md5
import hashlib
import time,random

class YouDaofanyi(object):

    def __init__(self,text):

        self.url = "http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule"
        self.method = "POST"
        self.headers = {
                        "Origin": "http://fanyi.youdao.com",
                        "Referer": "http://fanyi.youdao.com/",

                        "host" : "fanyi.youdao.com",
                        "Cookie": "xxxxxxxx"
                        }

        self.text = text
        utc =  int(time.time() * 1000)
        salt = utc*10 + random.randint(0,11)

        #print(utc,salt)
        signstr = ("fanyideskweb" + str(text) + str(salt) +"rY0D^0'nM0}g5Mm1z%1G4").encode("utf-8")
        md5 = hashlib.md5()
        md5.update(signstr)
        sign = md5.hexdigest()

        print("input text is       : %s" % text)
        post_data ={"i":text,
                   "smartresult":"dict",
                   "from":"AUTO",
                   "to":"AUTO",
                   "client":"fanyideskweb",
                   "salt":salt,

                   "typoResult":"false"
                   }
        self.data = parse.urlencode(post_data)

    def translate(self):
        test = requests.post(url = self.url,data= self.data,headers =self.headers)
        resultjson = test.json()

        if resultjson == {'errorCode': 50}:
            translate = ""
        else:
            try:
                translate = resultjson["translateResult"]
                translate = translate[0][0]["tgt"]
                print("translate result is : %s" % translate)
            except KeyError as f:
                translate =""

        return translate

　　

后面想到做一个小工具能翻译文本内容，又能翻译excel档文件，马上实现了，这里把翻译文本直接追加到对应的单元格。

#coding=utf-8

import xlrd,xlwt
from xlrd import *
import Translate
from xlutils.copy import copy

def TypeCheck(typename):
    flag = False
    if typename == 0:
        print("单元格内容为空")
    elif typename ==1:
        print("字符串，翻译中...")
        flag = True
    elif typename == 2:
        print("单元格为数字")
    elif typename ==3:
        print ("单元格为日期")
    elif typename == 4:
        print("单元格为布尔类型")
    else:
        print("格式获取错误")
    return flag

def Excelread(filename):
    rd = xlrd.open_workbook(filename)
    sheet = rd.sheet_by_index(0)
    readtext = []
    readalltext =[]
    for i in range(1000):
        for j in range(1000):
            try:
                valuetype = sheet.cell(i,j).ctype
                resulttype = TypeCheck(valuetype)
                if resulttype== False:
                    print("不需要进行翻译的内容")
                else:
                    value = sheet.cell_value(i, j)
                    translatevalue = Translate.translate(value)
                    newvalue = str(value) + translatevalue
                    ExcelWrite(filename,i,j,newvalue)
                    readtext.append(value)
            except IndexError as f:
                pass
        readalltext.append(readtext)
        readtext = []
    flag = False
    for i in range(len(readalltext)):
        if readalltext[i] != []:
            flag = True
            break
        else:
            pass
    return flag

def ExcelWrite(filename,raw,cow,value):
    rb = xlrd.open_workbook(filename)
    wt = copy(rb)
    s = wt.get_sheet(0)
    s.write(raw,cow,value)
    wt.save(filename)

　　

再加上tk部分代码：

    try:
        root = Tkinter.Tk()
        root.title("翻译工具")
        root.geometry("850x350")

        root.resizable(width=False, height=False)
        Tkinter.Label(root, text='有道翻译区域', fg='blue', font=("黑体", 20, "bold")).grid(row=0, column=2)
        Tkinter.Label(root, text='*Version: v0.1-20190329*', fg='blue', font=("黑体", 10)).grid(row=11, column=4)
        Tkinter.Label(root, text='*Design : Sandy1128*', fg='blue', font=("黑体", 10)).grid(row=12, column=4)

        Tkinter.Label(root,text='需要翻译的文本:',font=("黑体", 10)).grid(row=1,column=1)
        fanyitext_t=Tkinter.Text(root,height=5,width=60, fg='blue')
        fanyitext_t.grid(row=1,column=2)
        fanyitext_t.insert('0.0','123')

        Tkinter.Label(root, text='或需要翻译的文件路径:',font=("黑体", 10)).grid(row=2, column=1)
        fanyifname_t = Tkinter.Text(root, height=5, width=60, fg='blue')
        fanyifname_t.grid(row=2, column=2)

        fanyiinputfile =Tkinter.Button(root, text='浏览',activeforeground = "red",fg='blue',font=("黑体", 12, "bold"), height =2,command= selectfilefanyi)
        fanyiinputfile.grid(row = 2,column = 3)

        btn_fanyi=Tkinter.Button(root,text='开始翻译',activeforeground = "red",fg='black',font=("黑体", 12, "bold"),height = 2,command=qidongfanyiapp)
        btn_fanyi.grid(row=5,column=3)

        root.mainloop()

    except Exception as e:
        pass

视图：

可以将python代码打包成exe文件，方便使用。
