在 Node.js 的 HTTP 服务器开发中，ERR_HTTP_HEADERS_SENT: Cannot set headers after they are sent to the client at...如果在响应头发送后尝试再次设置响应头，Node.js 会抛出 ERR_HTTP_HEADERS_SENT 错误。...该错误的完整信息为：Cannot set headers after they are sent to the client at ServerResponse.setHeader，即在响应头已发送给客户端后...然而，代码在此之后没有终止函数的执行，继续执行 res.send()，这会导致尝试再次发送响应，从而引发 ERR_HTTP_HEADERS_SENT 错误。...总结ERR_HTTP_HEADERS_SENT 错误通常是由于在响应头已发送后再次尝试设置响应头引起的。为避免该错误，需要确保在发送响应后终止函数的执行，防止后续代码再次发送响应。
