message.url

• <string>

仅对从 http.Server 获得的请求有效。

¥Only valid for request obtained from http.Server.

请求的网址字符串。这仅包含实际 HTTP 请求中存在的网址。接受以下请求：

¥Request URL string. This contains only the URL that is present in the actual HTTP request. Take the following request:

GET /status?name=ryan HTTP/1.1
Accept: text/plain 拷贝

要将网址解析为它的部分：

¥To parse the URL into its parts:

new URL(`http://${process.env.HOST ?? 'localhost'}${request.url}`); 拷贝

当 request.url 为 '/status?name=ryan' 且 process.env.HOST 未定义时：

¥When request.url is '/status?name=ryan' and process.env.HOST is undefined:

$ node
> new URL(`http://${process.env.HOST ?? 'localhost'}${request.url}`);
URL {
  href: 'http://localhost/status?name=ryan',
  origin: 'http://localhost',
  protocol: 'http:',
  username: '',
  password: '',
  host: 'localhost',
  hostname: 'localhost',
  port: '',
  pathname: '/status',
  search: '?name=ryan',
  searchParams: URLSearchParams { 'name' => 'ryan' },
  hash: ''
} 拷贝

确保将 process.env.HOST 设置为服务器的主机名，或考虑完全替换这部分。如果使用 req.headers.host，请确保使用正确的验证，因为客户端可能会指定自定义 Host 标头。

¥Ensure that you set process.env.HOST to the server's host name, or consider replacing this part entirely. If using req.headers.host, ensure proper validation is used, as clients may specify a custom Host header.
