java - 在littleproxy中设置远程ip和端口

Question

在littleProxy中，如何设置远程IP和端口？他们网站上的示例:

HttpProxyServer server =
    DefaultHttpProxyServer.bootstrap()
        .withPort(8080)
        .start();

仅设置本地端口。

请求目标必须采用绝对形式(如 RFC 7230 第 5.3.2 节所指定)，才能由 LittleProxy 转发。以下代码适用于 LittleProxy v1.1.0beta1:

Pattern REQUEST_TARGET_ORIGIN_FORM_PREFIX = Pattern.compile("/[^/]");

@Override
public HttpResponse clientToProxyRequest(HttpObject httpObject) {
  if (httpObject instanceof HttpRequest) {
    HttpRequest httpRequest = (HttpRequest) httpObject;
    if (REQUEST_TARGET_ORIGIN_FORM_PREFIX.matcher(httpRequest.getUri()).lookingAt()) {
      String uriRemote = "http://myRemoteHost:myRemotePort" + httpRequest.getUri();
      httpRequest.setUri(uriRemote);
    }
  }
  return null;
}
