🔗 API调用最佳实践

1. 使用适当的请求头

curl -X GET http://localhost:3000/api/v1/cluster/status \ -H "Authorization: Bearer your_token_here" \ -H "Content-Type: application/json" \ -H "Accept: application/json"

2. 实现重试机制

import requests from requests.adapters import HTTPAdapter from urllib3.util.retry import Retry session = requests.Session() retry_strategy = Retry( total=3, backoff_factor=1, status_forcelist=[429, 500, 502, 503, 504] ) session.mount("http://", HTTPAdapter(max_retries=retry_strategy))

3. 处理分页数据

async function fetchAllVolumes() { let allVolumes = []; let page = 1; let hasMore = true; while (hasMore) { const response = await fetch(`/api/v1/volumes?page=${page}&limit=100`); const data = await response.json(); allVolumes = allVolumes.concat(data.volumes); hasMore = page < data.pagination.pages; page++; } return allVolumes; }
