我已经使用Service Worker来拦截对安全资源的HTTP请求，并向该请求添加授权标头（如果用户已经登录）。现在，我有一个场景，服务工作人员拦截POST请求以注入授权标头。但是，服务工作者未在请求有效负载中接收数据，因此没有请求有效负载（请参见屏幕截图2）。结果，nodejs中的后端验证逻辑失败，因为没有收到有效载荷数据。理想情况下，除了授权标头之外，后端代码还应该接收有效载荷数据以保留在DB中。有指导吗？

下面的第一个屏幕截图是带有有效负载的原始请求。第二个服务工作人员没有任何请求有效负载。

这是我的服务人员代码，用于拦截提取请求：

self.addEventListener('fetch',(event) => {
  const fetchEvent = event;
  const requestProcessor = (idToken) => {
    console.log('idToken in fetch '+idToken);
    let req = event.request;
    // For same origin https requests,append idToken to header.
    if (self.location.origin == getOriginFromUrl(event.request.url) &&
        (self.location.protocol == 'https:' ||
         self.location.hostname == 'localhost') &&
        idToken) {
      // Clone headers as request headers are immutable.
      const headers = new Headers();
      for (let entry of req.headers.entries()) {
        headers.append(entry[0],entry[1]);
      }
      // Add ID token to header. We can't add to Authentication header as it
      // will break HTTP basic authentication.
      headers.append('Authorization','Bearer ' + idToken);
      try {
        req = new Request(req.url,{
          method: req.method,headers: headers,mode: 'same-origin',credentials: req.credentials,cache: req.cache,redirect: req.redirect,referrer: req.referrer,body: req.body,bodyUsed: req.bodyUsed,context: req.context
        });
      } catch (e) {
        console.error('failed to prepare new header '+ e);
        // This will fail for CORS requests. We just continue with the
        // fetch caching logic below and do not pass the ID token.
      }
    }

    return fetch(req);

  };
  // Try to fetch the resource first after checking for the ID token.
// getIdToken() returns valid idtoken for logged in user.
  event.respondWith(getIdToken().then(requestProcessor,requestProcessor));
});
