重试示例

基础重试

import { Request } from '@ureq/core';
import { FetchRequestor } from '@ureq/impl-fetch';

const request = new Request(
  new FetchRequestor(),
  {
    retry: {
      maxRetries: 3,
      retryDelay: 1000
    }
  }
);

const data = await request.get('/api/users');

自定义重试条件

const request = new Request(
  new FetchRequestor(),
  {
    retry: {
      maxRetries: 3,
      shouldRetry: (error) => {
        // 只重试 5xx 错误
        return error.status >= 500 && error.status < 600;
      }
    }
  }
);

指数退避

let retryCount = 0;

const request = new Request(
  new FetchRequestor(),
  {
    retry: {
      maxRetries: 5,
      shouldRetry: (error) => {
        if (error.status >= 500) {
          retryCount++;
          const delay = Math.pow(2, retryCount - 1) * 1000;
          return new Promise(resolve => {
            setTimeout(() => resolve(true), delay);
          });
        }
        return false;
      }
    }
  }
);
