python調用有道翻譯api實現翻譯

通過調用有道翻譯的api,實現中譯英、其他語言譯中文

代碼:

# coding=utf-8
import urllib
import urllib2
import json
import time
import hashlib


class YouDaoFanyi:
    def __init__(self, appKey, appSecret):
        self.url = 'https://openapi.youdao.com/api/'

        }
        self.appKey = appKey  # 應用id
        self.appSecret = appSecret  # 應用密鑰
        self.langFrom = 'auto'   # 翻譯前文字語言,auto為自動檢查
        self.langTo = 'auto'     # 翻譯后文字語言,auto為自動檢查

    def getUrlEncodedData(self, queryText):
        '''
        將數據url編碼
        :param queryText: 待翻譯的文字
        :return: 返回url編碼過的數據
        '''
        salt = str(int(round(time.time() * 1000)))  # 產生隨機數 ,其實固定值也可以,不如"2"
        sign_str = self.appKey + queryText + salt + self.appSecret
        sign = hashlib.md5(sign_str).hexdigest()
        payload = {
            'q': queryText,
            'from': self.langFrom,
            'to': self.langTo,
            'appKey': self.appKey,
            'salt': salt,
            'sign': sign
        }

        # 注意是get請求，不是請求
        data = urllib.urlencode(payload)
        return data

    def parseHtml(self, html):
        '''
        解析頁面，輸出翻譯結果
        :param html: 翻譯返回的頁面內容
        :return: None
        '''
        data = json.loads(html)
        print '-' * 10
        translationResult = data['translation']
        if isinstance(translationResult, list):
            translationResult = translationResult[0]
        print translationResult
        if "basic" in data:
            youdaoResult = "\n".join(data['basic']['explains'])
            print '有道詞典結果'
            print youdaoResult
        print '-' * 10

    def translate(self, queryText):
        data = self.getUrlEncodedData(queryText)  # 獲取url編碼過的數據
        target_url = self.url + '?' + data    # 構造目標url
        request = urllib2.Request(target_url, headers=self.headers)  # 構造請求
        response = urllib2.urlopen(request)  # 發送請求
        self.parseHtml(response.read())    # 解析，顯示翻譯結果


if __name__ == "__main__":
    appKey = '應用id'  # 應用id
    appSecret = '應用密鑰'  # 應用密鑰
    fanyi = YouDaoFanyi(appKey, appSecret)
    while True:
        queryText = raw_input("請輸入你好翻譯的文字[Q|quit退出]: ").strip()
        if queryText in ['Q', 'quit']:
            break
        fanyi.translate(queryText)
