response.addTrailers(headers)

• headers <Object>

此方法向响应添加 HTTP 尾随标头（标头，但位于消息末尾）。

尝试设置包含无效字符的标头字段名称或值将导致抛出 TypeError。

• headers <Object>

This method adds HTTP trailing headers (a header but at the end of the message) to the response.

Attempting to set a header field name or value that contains invalid characters will result in a TypeError being thrown.
