EdgeOne Pages Functions 中 Request Header Host 奇奇怪怪的问题 • Zinc233's Blog

如题，EdgeOne Pages 中 Edge 和 Node Functions 中 Request Header Host 并不一样，

Edge Functions: 指向的是自己的域名
Node Functions: 指向的是CDN的域名

因此，Node Functions 中使用相对路径导航大概率会出错，如 fetch('/xxx')

问题排查#

在 Edge Functions 和 Node Functions 均部署以下代码，

export async function onRequest({request}) {
  // 获取request的详细信息
  const requestInfo = {
    url: request.url,
    method: request.method,
    headers: {},
    redirect: request.redirect,
    referrer: request.referrer,
    referrerPolicy: request.referrerPolicy,
  };

  // 获取所有的请求头
  for (const [key, value] of request.headers.entries()) {
    requestInfo.headers[key] = value;
  }

  // 将request信息转换为格式化的JSON字符串
  const requestInfoString = JSON.stringify(requestInfo, null, 2);

  return new Response(
    `hi from <edge/node>\nRequest Info:\n${requestInfoString}`,
    {
      headers: {
        'content-type': 'application/json; charset=UTF-8',
        'Access-Control-Allow-Origin': '*',
      },
    }
  );
}

Deploy 环境#

Edge Functions#

在 Edge Functions ↗ 下访问，得到的结果如下，其 url 和 Host 都是指向访问的域名的。

Node Functions#

在 Node Functions 下访问，之前测试的结果 url 和 Host 似乎指向的是CDN的域名。

不知道为什么，后面再次部署这个函数生产环境一直超时崩溃，无法复现了😂

Dev 环境#

奇怪的是，在本地，结论和上面是相反的。

Edge Functions#

访问本地 http://localhost:8088/edge，这边的 url 和 Host 指向了一个临时的域名
