chatGPT官网经常会因为系统升级等情况而不能用, 有时候响应也特别慢, 于是API排上用场. 

之前写了一个简易的命令窗式的问答, 能多轮对话, 还能保存对话, 但是输入很不方便. 

 回头一看额度才用了4毛钱, 于是在api免费期限还剩一个一个月的时候写了一个对话界面, 目前只是单轮对话,后期将加入更多功能, 尽最大努力用完剩下余额. 

API接口

首先是chatGPT的接口, 这个网上例程很多, 主要是返回消息和所耗费的taken.

import os
import openai
import json
# from main_window import *
if os.getenv('chatgpt_key'):openai.api_key = os.getenv('chatgpt_key')
else:openai.api_key_path = "E:\chatgpt\key.txt"def connect(message):response = openai.ChatCompletion.create(model="gpt-3.5-turbo",messages=message)message = response["choices"][0]["message"]token = int(response["usage"]["total_tokens"])return token, message

主界面

主界面采用tkinter, 利用chatGPT先生成一个简单示例, 然后在此基础上不断优化界面, 在不拥专门学习这个库的情况下就能写出外观不错的界面, 可以很容易修改输入内容. 同时能够显示对话耗费了多少taken, 换算的多少刀.

 

代码如下, 没太注意格式风格, 只为快速迭代

后续有空了再加人更多功能, 例如对本地数据库文献库的管理, 还可以结合单机的本地模型. 实现高效学习和工作
