message.headersDistinct

• <Object>

类似于 message.headers，但没有连接逻辑，并且值始终是字符串数组，即使对于仅收到一次的标头也是如此。

// 打印如下内容：
//
// { 'user-agent': ['curl/7.22.0'],
//   host: ['127.0.0.1:8000'],
//   accept: ['*/*'] }
console.log(request.headersDistinct);

• <Object>

Similar to message.headers, but there is no join logic and the values are always arrays of strings, even for headers received just once.

// Prints something like:
//
// { 'user-agent': ['curl/7.22.0'],
//   host: ['127.0.0.1:8000'],
//   accept: ['*/*'] }
console.log(request.headersDistinct);
