爬虫系列更新-第二篇文章——《Python爬虫系列-有道批量翻译英文单词-注音标版》
之前发布计算机英文单词时研究了下,怎么把一个含有大量英文单词的txt文件翻译成如下格式：
如上图,左边图片是需要翻译的txt文本,右边图片是翻译后的txt文本。
运行的实际界面效果。
python代码参考了CSDN上的这个作者的帖子，他的分析博文很牛，但是没有批量翻译功能，所以我在他的代码的基础上添加了翻译中文、写入国际音标的功能，全部代码如下：
import hashlib
import base64
import requests
import json

from Crypto.Util.Padding import unpad, padclass AESCipher(object):key = b'ydsecret://query/key/B*RGygVywfNBwpmBaZg*WT7SIOUP2T0C9WHMZN39j^DAdaZhAnxvGcCY6VYFwnHl'iv = b'ydsecret://query/iv/C@lZe2YzHtZ2CYgaXKSVfsb7Y4QWHjITPPZ0nQp87fBeJ!Iv6v^6fvi2WN@bYpJ4'iv = hashlib.md5(iv).digest()key = hashlib.md5(key).digest()@staticmethoddef decrypt(data):# AES解密cipher = AES.new(AESCipher.key, AES.MODE_CBC, iv=AESCipher.iv)decrypted = cipher.decrypt(base64.b64decode(data, b'-_'))unpadded_message = unpad(decrypted, AES.block_size).decode()return unpadded_message@staticmethoddef encrypt(plaintext: str):# AES加密cipher = AES.new(AESCipher.key, AES.MODE_CBC, iv=AESCipher.iv)plaintext = plaintext.encode()padded_message = pad(plaintext, AES.block_size)encrypted = cipher.encrypt(padded_message)encrypted = base64.b64encode(encrypted, b'-_')return encrypteddef get_form_data(sentence, from_lang, to_lang):"""构建表单参数:param :sentence:翻译内容:param from_lang:源语言:param to_lang:目标语言:return:"""e = 'fsdsogkndfokasodnaso'd = 'fanyideskweb'u = 'webfanyi'm = 'client,mysticTime,product'p = '1.0.0'b = 'web'f = 'fanyi.web't = time.time()query = {'client': d,'mysticTime': t,'product': u,'key': e}# 获取sign值 - -密钥值h = hashlib.md5(urlencode(query).encode('utf-8')).hexdigest()form_data = {'i': sentence,'from': from_lang,'to': to_lang,'domain': 0,'dictResult': 'true','keyid': u,'sign': h,'client': d,'product': u,'appVersion': p,'vendor': b,'pointParam': m,'mysticTime': t,'keyfrom': f}return form_datadef translate(sentence, from_lang='auto', to_lang=''):""":param sentence:需翻译的句子:param from_lang:源语言:param to_lang:目标语言:return:"""# 有道翻译网页请求参数url = 'https://dict.youdao.com/webtranslate'headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36','referer': 'https://fanyi.youdao.com/','cookie': 'OUTFOX_SEARCH_USER_ID=-805044645@10.112.57.88; OUTFOX_SEARCH_USER_ID_NCOO=818822109.5585971;'}params = get_form_data(sentence, from_lang, to_lang)res = requests.post(url, headers=headers, data=params)# 翻译结果进行AES解密cipher = AESCipherret = json.loads(cipher.decrypt(res.text))#ret1 = json.dumps(ret,indent=4,ensure_ascii=False,sort_keys=False,separators=(",",";"))try:out = "英:[" + ret["dictResult"]["ec"]["word"]["ukphone"] + "] " + "美:[" + ret["dictResult"]["ec"]["word"]["usphone"] + "]"trans = ret["dictResult"]["ec"]["word"]["trs"]tgt = ret['translateResult'][0][0]['tgt']out = out + " 译:[" + tgt + "]"#for tran in trans:#if 'pos' in tran:#out = out + " " + tran['pos'] + " " + tran['tran']#print(out)return outexcept Exception as e:print('翻译失败：', e)return 0if __name__ == '__main__':path = input("请输入你要翻译的txt文档路径(E:\1.txt): ")# result = translate(word)out = ""with open(path,'r') as f:lines = f.readlines()for line in lines:print(line.replace("\n","").replace("\r",""))result = translate(line)#'zh-CHS', 'ja')if result:out = out + line.replace("\n","").replace("\r","") + " " + result + "\n"#print(out)#print('翻译结果：\n', result)f.close()with open(path[:-4] + "_已翻译.txt",'w',encoding='utf-8') as fout:fout.write(out)fout.close()print(out)print("已完成!")调用方法如下:
把代码保存到.py文件中,运行.py文件,输入需要翻译的txt文本路径地址,如下图所示:
然后翻译后的txt，也会出现在之前的文本文件目录里,如下图: 
上图中"1.txt"就是输入的英文文档,"1_已翻译.txt"就是翻译后的文档。
