Question: How to catch and handle "Network Error" in Vue Axios?

Answer:

step:

1. Define an error handling function:

    <code class="js">const errorHandler = (e) => { // 处理错误};</code>

2. Use the response interceptor to add an error handler:

    <code class="js">axios.interceptors.response.use( (response) => response, (error) => errorHandler(error) );</code>

Example:

 <code class="js">const errorHandler = (e) => { if (e.response) { // 请求已发送，服务器响应了状态代码console.error(e.response.data); console.error(e.response.status); console.error(e.response.headers); } else if (e.request) { // 请求已被发送，但没有收到服务器响应console.error(e.request); } else { // 发生了其他错误，可能是由于设置请求时出错console.error(e.message); } console.error(e.config); }; axios.interceptors.response.use( (response) => response, (error) => errorHandler(error) );</code>
