axios-retry

Axios 插件 重试失败的请求



安装

npm install axios-retry

使用

// CommonJS
// const axiosRetry = require('axios-retry');

// ES6
import axiosRetry from 'axios-retry';

axiosRetry(axios, { retries: 3 });

axios.get('http://example.com/test') // The first request fails and the second returns 'ok'
  .then(result => {
    result.data; // 'ok'
  });

// Exponential back-off retry delay between requests
axiosRetry(axios, { retryDelay: axiosRetry.exponentialDelay});

// Custom retry delay
axiosRetry(axios, { retryDelay: (retryCount) => {
  return retryCount * 1000;
}});

// 自定义 axios 实例
const client = axios.create({ baseURL: 'http://example.com' });
axiosRetry(client, { retries: 3 });

client.get('/test') // 第一次请求失败，第二次成功
  .then(result => {
    result.data; // 'ok'
  });

// 允许 request-specific 配置
client
  .get('/test', {
    'axios-retry': {
      retries: 0
    }
  })
  .catch(error => { // The first request fails
    error !== undefined
  });

备注: 除非 shouldResetTimeout被设置, 这个插件
将请求超时解释为全局值, 不是针对每一个请求，二是全局的设置

配置

Name Type Default Description
retries Number 3 The number of times to retry before failing.
retryCondition Function isNetworkOrIdempotentRequestError 如果应该重试请求，则进一步控制的回调。默认情况下，如果是幂等请求的网络错误或5xx错误，它会重试(GET, HEAD, OPTIONS, PUT or DELETE).
shouldResetTimeout Boolean false Defines if the timeout should be reset between retries
retryDelay Function function noDelay() { return 0; } 控制重试请求之间的延迟。默认情况下，重试之间没有延迟。另一个选项是exponentialDelay (Exponential Backoff). The function is passed retryCount and error.
