无法从AWS Lambda @ Edge检索正确的uri

Question

我想从我的lambda @ edge函数中检索当前URI，但是event.Records[0].cf.request对象太奇怪了。

当我从如下卷曲中触发我的lambda时： curl -H 'user-agent: googlebot' https://example.com/en/test

然后我console.log无法检索/en/test的事件对象。

另一个奇怪的是，我无法在事件对象中看到标头“ user-agent：googlebot”。

基础结构：

Cloudfront->（查看者请求）lambda edge（console.log（event））-> S3存储桶（通过VueJS网站）

Lambda @ edge：

// viewer-request
exports.handler = (event, context, callback) => {
  console.log(JSON.stringify(event));
  const request = event.Records[0].cf.request;
  const headers = request.headers;
  const user_agent = headers['user-agent'];
  const host = headers['host'];
  if (user_agent && host) {
    let prerender = /googlebot|adsbot\-google|Feedfetcher\-Google|bingbot|yandex|baiduspider|Facebot|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora link preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator/i.test(user_agent[0].value);
    prerender = prerender || /_escaped_fragment_/.test(request.querystring);
    prerender = prerender && ! /\.(js|css|xml|less|png|jpg|jpeg|gif|pdf|doc|txt|ico|rss|zip|mp3|rar|exe|wmv|doc|avi|ppt|mpg|mpeg|tif|wav|mov|psd|ai|xls|mp4|m4a|swf|dat|dmg|iso|flv|m4v|torrent|ttf|woff|svg|eot)$/i.test(request.uri);
    if (prerender) {
      headers['x-prerender-token'] = [{ key: 'X-Prerender-Token', value: 'token'}];
      headers['x-prerender-host'] = [{ key: 'X-Prerender-Host', value: host[0].value}];
      headers['x-prerender-cachebuster'] = [{ key: 'X-Prerender-Cachebuster', value: Date.now().toString()}];
    }
  }
  callback(null, request);
};

console.log（JSON.stringify（event））
