Ren'Py游戏 机器翻译实现

完成了Ren'Py的机器翻译

这里写一下主要部分

建立中文滤器

def chinese_filter(s):
    return generic_filter(s, chinese_transform)

判断字符串是否含有英文，含有的需要翻译，
如 (have)，纯其他字符不需要，如()，不然传到百度API会返回
{u'error_code': u'54001', u'error_msg': u'Invalid Sign'}
相当于一层简单过滤

def isWords(s):
    for letter in s:
      if letter.isalpha():
          return True
    return False

这里是修改的transform

def chinese_transform(s):
    """
    here is my add.  use baidu API to translate english/or other language to chinese.
    """
    print("---------------------------------------------------------------------")
    try:
        print("sentence:  " + s)
    except Exception, e:
        print("*********Exception***********")
        print(e)
        return s

    if isWords(s):        
        appid = "你的百度翻译APPID"
        apiSecretKey = '你的百度翻译KEY'

        httpClient = None
        myurl = '/api/trans/vip/translate'
        q = s
        fromLang = 'en'
        toLang = 'zh'
        salt = random.randint(32768, 65536)

        # print("sentence:  " + q)
        apiSign = appid+q+str(salt)+apiSecretKey
        m1 = md5.new()
        m1.update(apiSign)
        apiSign = m1.hexdigest()
        myurl = myurl+'?appid='+appid+'&q='+urllib.quote(q.encode('utf-8'))+'&from='+fromLang+'&to='+toLang+'&salt='+str(salt)+'&sign='+apiSign
        try:
            httpClient = httplib.HTTPConnection('api.fanyi.baidu.com')
            httpClient.request('GET', myurl)

            response = httpClient.getresponse()
            result_all = response.read()
            result = json.loads(result_all)
            print(result)
            # real_s = result["trans_result"][0]["dst"]
            return result["trans_result"][0]["dst"]
        except Exception, e:
            print("*********Exception***********")
            print(e)
        finally:
            if httpClient:
                httpClient.close()
        return s
        # print("sentence:  " + s)

    else:
        # print("--------------------------------------------------")
        return s

class Logger(object):
    def __init__(self, fileN="Default.log"):
        self.terminal = sys.stdout
        self.log = open(fileN, "a")
        # self.log = open(fileN, "a")

    def write(self, message):
        self.terminal.write(message)
        self.log.write(message)

    def flush(self):
        pass


sys.stdout = Logger("D:\\12345.txt")

主要是

urllib.quote(q.encode('utf-8'))
注意这里q的编码
其次，注意异常捕获之后的处理
还有Logger类的使用，方便调试
