## python之批量翻译

#### 一、有道翻译接口

**以该demo为例,调用接口用不用加密、headers传不传都可以,等访问次数达到一定量就不行了了(目前我试过的都是,更换ip访问也是不行),如果数据量不大,可以用此方法**

```python

from openpyxl import load_workbook

import requests

import hashlib

import time

import urllib.parse

#创建md5对象

def nmd5(str):

m = hashlib.md5()

# Tips

# 此处必须encode

# 若写法为m.update(str) 报错为： Unicode-objects must be encoded before hashing

# 因为python3里默认的str是unicode

# 或者 b = bytes(str, encoding='utf-8')，作用相同，都是encode为bytes

b = str.encode(encoding='utf-8')

m.update(b)

str_md5 = m.hexdigest()

return str_md5

def formdata(transtr):

# 待加密信息

headerstr = '5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36'

#print(round(time.time()*1000))

bv=nmd5(headerstr)

ts=str(round(time.time()*1000))

salt=ts+'90'

strexample='fanyideskweb'+transtr+salt+'n%A-rKaT5fb[Gy?;N5@Tj'

sign=nmd5(strexample)

#print(sign)

i=len(transtr)

#print(i)

# print('MD5加密前为 ：' + headerstr)

# print('MD5加密后为 ：' + bv)

dict={'i':transtr,'from':'AUTO','TO':'AUTO','smartresult': 'dict',

'client':'fanyideskweb',

'salt':salt,

'sign':sign,

'ts':ts,

'bv':bv,

'doctype':'json',

'version':'2.1',

'keyfrom':'fanyi.web',

'action':'FY_BY_REALTlME'

}

return dict

workbook = load_workbook(r'xxxxx')

sheet = workbook['Sheet1']

for row in range(1146, 1600):

s = ''

name = sheet.cell(row=row, column=6).value

url='http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule'

header={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36',

'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8',

}

dict=formdata(name)

dict=urllib.parse.urlencode(dict)

dict=str(dict)

#dict=urllib.parse.urlencode(dict).encode('utf-8')

try:

req = requests.post(url, data=dict, headers=header)

val = req.json()

translate_result = val['translateResult'][0]

except Exception as e:

print(e)

else:

if len(translate_result) > 1:

# print(len(translate_result))

for i in range(len(translate_result)):

s = s + translate_result[i]["tgt"]

sheet.cell(row=row, column=7, value=s)

print(row)

else:

translate = translate_result[0]["tgt"]

sheet.cell(row=row, column=7, value=translate)

print(row)

time.sleep(1)

workbook.save('xxxxx')

print('翻译结束')

```

#### 二、python的第三方库(from translate import Translator)

**下载: pip install translate (该库下载比较慢,耐心等待)**

**该方法也是有字符限制 , 翻译到一定字符就开始返回,意思就是说翻译达到了上限

MYMEMORY WARNING: YOU USED ALL AVAILABLE FREE TRANSLATIONS FOR TODAY. NEXT AVAILABLE IN 15 HOURS 22 MINUTES 17 SECONDSVISIT HTTPS://MYMEMORY.TRANSLATED.NET/DOC/USAGELIMITS.PHP TO TRANSLATE MORE**

```python

from openpyxl import load_workbook

from translate import Translator

workbook = load_workbook(r'xxxx.xlsx')

sheet = workbook['Sheet1']

translator = Translator(to_lang='zh')

for row in range(2167, 3000):

key = sheet.cell(row=row, column=6).value

if len(key) > 500:

a = key[:500]

b = key[500:]

sheet.cell(row=row, column=7, value=translator.translate(a)+translator.translate(b))

else:

sheet.cell(row=row, column=7, value=translator.translate(key))

# print(translator.translate(key))

print(row)

workbook.save('xzxxx.xlsx')

print('翻译结束')

```

#### 三、百度翻译接口

**百度翻译接口免费版的可以的, 就是限制访问时间, 平均每秒访问一次, 数据量大的话, 速度稍微有点慢

当然你有富裕的可以开通豪华版**

**百度接口就不做过多介绍了, 百度翻译开放平台介绍的很详细:

大佬如果有更好的方法,请多多赐教, 谢谢!
