1、提示

由于国内注册 https://api.openai.com 比较麻烦，直接购买的第三方接口和key
淘宝购买，几块钱1个月
3、自己娱乐够用

2、前端框架

Vant 移动端使用
axios

3、创建拦截器，api/request.js

/*

 */
import axios from 'axios'
// 创建axios实例
const service = axios.create({
  timeout: 300 * 1000, // ms请求超时时间
})

// request拦截器
service.interceptors.request.use(
  (config) => {
    return config
  },
  (error) => {
    // Do something with request error
    Promise.reject(error)
  }
)

// respone拦截器
service.interceptors.response.use(
  (response) => {
    const res = response
    if (res.status !== 200) {
      return Promise.reject(response)
    } else {
      if (res.status === 200) {
        return res.data
      } else {
        return Promise.reject(res.data.message)
      }
    }
  },
  (error) => {
    return Promise.reject(error)
  }
)

export default service

4、创建接口 api/index.js

import service from './request'
// 访问接口地址
const baseUrl = window.configUrl.openApi
const openAi = (data) =>
  service({
    url: baseUrl + '/v1/chat/completions',
    method: 'post',
    headers: {
      'content-type': 'application/json',
      Authorization:
        'Bearer YOU-KEY-63D8A64444655655C56a0838490e',
    },
    data,
  })
export default { openAi }
