给axios进行全局统一返回的定义

request.ts

import axios from 'axios';

// 创建请求实例
const instance = axios.create({
  baseURL: import.meta.env.VITE_BASE_URL,
  timeout: 300000, // 指定请求超时的毫秒数
  withCredentials: false, // 表示跨域请求时是否需要使用凭证
});

// 前置拦截器（发起请求之前的拦截）
instance.interceptors.request.use(
  (config) => {
    // const token = getToken()
    // if (token) {
    //  config.headers.token = token
    // }
    return config;
  },
  (error) => {
    return Promise.reject(error);
  }
);

// 后置拦截器（获取到响应时的拦截）
instance.interceptors.response.use(
  (response) => {
    // 根据你的项目实际情况来对 response 和 error 做处理
    // 这里对 response 和 error 不做任何处理，直接返回
    return response;
  },
  (error) => {
    const { response } = error;
    if (response && response.data) {
      return Promise.reject(error);
    }
    const { message } = error;
    console.error(message);
    return Promise.reject(error);
  }
);
