Python和Haskell联合开发一个聊天机器人

Python和Haskell是两种不同的编程语言，可以在联合开发中实现聊天机器人。下面是一个使用Python和Haskell开发的聊天机器人的示例，以展示如何使用这两种语言合作开发。

Python部分:

import requests

def get_response(message):
    url = 'https://api.openai.com/v1/engines/davinci-codex/completions'
    headers = {
        'Authorization': 'Bearer YOUR_OPENAI_API_KEY',
        'Content-Type': 'application/json'
    }
    data = {
        'prompt': message,
        'max_tokens': 50
    }
    response = requests.post(url, headers=headers, json=data)
    result = response.json()
    return result['choices'][0]['text']

while True:
    message = input('You: ')
    response = get_response(message)
    print('ChatBot:', response)

Haskell部分:

import Data.Aeson (Value, eitherDecode, decode)
import Network.HTTP.Simple (httpJSON, parseRequest, setRequestBodyJSON, setRequestHeader)
import Data.ByteString.Lazy.Char8 (pack)

getResponse :: String -> IO (Maybe String)
getResponse message = do
  request <- parseRequest "POST https://api.openai.com/v1/engines/davinci-codex/completions"
  let headers = [("Authorization", "Bearer YOUR_OPENAI_API_KEY"), ("Content-Type", "application/json")]
      body = "{\"prompt\": \"" ++ message ++ "\", \"max_tokens\": 50}"
      requestWithHeaders = setRequestBodyJSON (eitherDecode (pack body) :: Either String Value) $ setRequestHeader headers request
  response <- httpJSON requestWithHeaders
  let result = getResponseText $ responseBody response
  return result

getResponseText :: JsonResponse -> Maybe String
getResponseText response =
  case eitherDecode response :: Either String Response of
    Left _ -> Nothing
    Right res -> Just (getText res)

data JsonResponse = JsonResponse {
  responseData :: Response
}

instance FromJSON JsonResponse where
  parseJSON = withObject "Response" $ \v -> JsonResponse <$> v .: "choices"

data Response = Response {
  responseText :: String
}

instance FromJSON Response where
  parseJSON = withObject "Message" $ \v -> Response <$> v .: "text"

getText :: Response -> String
getText (Response response) = response

main :: IO ()
main = do
  putStrLn "ChatBot: Hello! How can I help you?"
  loop

loop :: IO ()
loop = do
  putStr "You: "
  message <- getLine
  response <- getResponse message
  case response of
    Just text -> do
      putStrLn $ "ChatBot: " ++ text
      loop
    Nothing -> do
      putStrLn "An error occurred. Please try again."
      loop

以上代码分别展示了Python和Haskell两种编程语言的聊天机器人实现方式。两种语言都使用了OpenAI的API来生成机器人的回复。你可以使用自己的OpenAI API密钥替换代码中的YOUR_OPENAI_API_KEY。

在聊天机器人的主循环中，用户输入一条消息，然后通过API调用发送到OpenAI服务器以获取机器人的回复。Python部分使用requests库来发送HTTP请求，而Haskell部分使用了http-simple库。在得到机器人的回复后，回复消息将被打印到控制台。
