在main.ts引入
import axios from 'axios';
axios.defaults.baseURL = process.env.VUE_APP_SERVER;/*** axios拦截器*/
axios.interceptors.request.use(function (config) {console.log('请求参数：', config);return config;
}, error => {return Promise.reject(error);
});
axios.interceptors.response.use(function (response) {console.log('返回结果：', response);return response;
}, error => {console.log('返回错误：', error);const response = error.response;return Promise.reject(error);
});
