python实现在线翻译功能

对于需要大量翻译的数据，人工翻译太慢，此时需要使用软件进行批量翻译。

1.使用360的翻译

def fanyi_word_cn(string): url='https://fanyi.so.com/index/search' #db_path = ’./db/tasks.db’ Form_Data= {} #这里输入要翻译的英文 Form_Data[’query’]= string Form_Data[’eng’]= ’1’ #用urlencode把字典变成字符串，#服务器不接受字典，只接受字符串和二进制 data= parse.urlencode(Form_Data).encode(’utf-8’) #改成服务器可识别的数据后，请求，获取回应数据 response= request.urlopen(url, data) html= response.read().decode('utf-8')#解码方式 #java中的对象（集合）和数组（元素为集合）,loads可转Python字典 result= json.loads(html) #字典调取键名data下的键名fanyi,获取其值 translate_result= result['data']['fanyi'] #print(translate_result) return translate_result

2.使用Google自带的API来翻译

注意，需要安装API模块即可。

pip install translator

#google api, per 1000 words everydaydef translate_cn_api(content): translator= Translator(to_lang='zh') translation = translator.translate(content) return translation

3.使用Google翻译来做，是由于Google提供的API有字节限制，每天只能翻译1000字。

备注：环境准备

3.1 java环境

3.2 安装execjs模块

pip install PyExecJS

3.3 两个实现模块

HandleJs.py

#coding=utf-8import execjs class Py4Js(): def __init__(self): self.ctx = execjs.compile(''' function TL(a) { var k = ''; var b = 406644; var b1 = 3293161072; var jd = '.'; var $b = '+-a^+6'; var Zb = '+-3^+b+-f'; for (var e = [], f = 0, g = 0; g < a.length; g++) { var m = a.charCodeAt(g); 128 > m ? e[f++] = m : (2048 > m ? e[f++] = m >> 6 | 192 : (55296 == (m & 64512) && g + 1 < a.length && 56320 == (a.charCodeAt(g + 1) & 64512) ? (m = 65536 + ((m & 1023) << 10) + (a.charCodeAt(++g) & 1023), e[f++] = m >> 18 | 240, e[f++] = m >> 12 & 63 | 128) : e[f++] = m >> 12 | 224, e[f++] = m >> 6 & 63 | 128), e[f++] = m & 63 | 128) } a = b; for (f = 0; f < e.length; f++) a += e[f], a = RL(a, $b); a = RL(a, Zb); a ^= b1 || 0; 0 > a && (a = (a & 2147483647) + 2147483648); a %= 1E6; return a.toString() + jd + (a ^ b) }; function RL(a, b) { var t = 'a'; var Yb = '+'; for (var c = 0; c < b.length - 2; c += 3) { var d = b.charAt(c + 2), d = d >= t ? d.charCodeAt(0) - 87 : Number(d), d = b.charAt(c + 1) == Yb ? a >>> d: a << d; a = b.charAt(c) == Yb ? a + d & 4294967295 : a ^ d } return a } ''') def getTk(self,text): return self.ctx.call('TL',text)

此处实现了德语翻译成中文和英文翻译成中文。
