if (! response.data.hasError) { this .$message.success("数据获取成功!" ); const results = response.data.result; } else { this .$message.error("数据获取失败!" ); . catch ((error) => { clearTimeout(timer); if (error.response) { this .$message.error("数据获取失败!" );

注意: 可以使用同一个 cancel token 取消多个请求

二、设置超时时间,超时重新请求

配置axios拦截器

axios.interceptors.response.use(undefined, function axiosRetryInterceptor(err) {
    var config = err.config;
    // If config does not exist or the retry option is not set, reject
    if(!config || !config.retry) return Promise.reject(err);
    // Set the variable for keeping track of the retry count
    config.__retryCount = config.__retryCount || 0;
    // Check if we've maxed out the total number of retries
    if(config.__retryCount >= config.retry) {
        // Reject with the error
        return Promise.reject(err);
    // Increase the retry count
    config.__retryCount += 1;
    // Create new promise to handle exponential backoff
    var backoff = new Promise(function(resolve) {
        setTimeout(function() {
            resolve();
        }, config.retryDelay || 1);
    // Return the promise in which recalls axios to retry the request
    return backoff.then(function() {
        return axios(config);

参数说明:

1.retry - 第一次请求失败后重试请求的次数。
2.retryDelay -在失败请求之间等待的毫秒数(默认为1)。

axios.get('/some/endpoint', { retry: 5, retryDelay: 1000 })
    .then(function(res) {
        console.log('success', res.data);
    .catch(function(err) {
        console.log('failed', err);
