GoldenDict调用百度领域翻译api

百度领域翻译API文档

前言

收到一封百度的推广邮件，升级针对行业领域翻译的API，浅浅尝试一下

思路

通过 Goldendict 调用 python脚本 发送 get 请求，并显示

完整的 get 请求是这样的，只需要将要查询的内容拼接进去，然后调用就好了

http://api.fanyi.baidu.com/api/trans/vip/translate?q=apple&from=en&to=zh&appid=2015063000000001&salt=1435660288&sign=f89f9594663708c1605f3d736d01d2d4

• appid 和 key需要通过注册开发者，填写身份信息后才能获取

代码实现

import hashlib
import json
import urllib
import random

import re

#main
def baidu_translate_goldendict(content):
    """

def target_language(content):
    targetLanguage = "zh"
    zhPattern = re.compile(u'^[\u4e00-\u9fa5]')
    match = zhPattern.search(content)
    if match:
        targetLanguage = "en"

    content_baidu_translate(content,targetLanguage)
    pass

    # Step1 拼接字符串
    sign = appid + q + str(salt) + domain + secretKey

    # Step2 对字符串1做md5，得到32位小写sign
    sign = hashlib.md5(sign.encode()).hexdigest()
