我是Java的新手,我希望Apache HttpCore库有一些方向。
我编写了一个简单的服务器,并希望实现一些自定义HTTP方法。我已经阅读了几次文档,但还是没能弄明白。
看起来在HttpService.doService()中引发了501 Not Implemented,但是覆盖该方法不起作用。我的请求处理程序没有被调用。
任何帮助将不胜感激。
感谢。
以下是我所得到的要点:
ServerSocket serverSocket;
HttpParams params;
HttpService httpService;
serverSocket = new ServerSocket(8000);
params = new BasicHttpParams();
params.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 5000);
params.setIntParameter(CoreConnectionPNames.SOCKET_BUFFER_SIZE, 8 * 1024);
params.setBooleanParameter(CoreConnectionPNames.STALE_CONNECTION_CHECK, false);
params.setBooleanParameter(CoreConnectionPNames.TCP_NODELAY, true);
params.setParameter(CoreProtocolPNames.ORIGIN_SERVER, "?");
BasicHttpProcessor httpproc = new BasicHttpProcessor();
httpproc.addInterceptor(new ResponseDate());
httpproc.addInterceptor(new ResponseServer());
httpproc.addInterceptor(new ResponseContent());
httpproc.addInterceptor(new ResponseConnControl());
HttpRequestHandlerRegistry registry = new HttpRequestHandlerRegistry();
registry.register("*", new HttpRequestHandler() {
public void handle(HttpRequest request, HttpResponse response,
HttpContext context) throws HttpException, IOException {
System.out.println(request.getRequestLine().toString());
}
});
httpService = new HttpService(httpproc, new DefaultConnectionReuseStrategy(), new DefaultHttpResponseFactory());
httpService.setParams(params);
httpService.setHandlerResolver(registry);
Socket socket = serverSocket.accept();
DefaultHttpServerConnection conn = new DefaultHttpServerConnection();
conn.bind(socket, params);
HttpContext context = new BasicHttpContext();
httpService.handleRequest(conn, context);
socket.close();
conn.shutdown();
serverSocket.close();
响应:
# curl -X FOO -i http://127.0.0.1:8000
HTTP/1.0 501 Not Implemented
Content-Length: 26
Content-Type: text/plain; charset=US-ASCII
Connection: Close
FOO method not supported
请求行不会写入System.out,除非方法是GET,POST等。
解决方案:我需要实现一个HttpRequestFactory。 e.g:
DefaultHttpServerConnection conn = new DefaultHttpServerConnection() {
@Override
public DefaultHttpRequestFactory createHttpRequestFactory() {
return new DefaultHttpRequestFactory() {
@Override
public HttpRequest newHttpRequest(final RequestLine requestline) {
return new BasicHttpRequest(requestline);
}
@Override
public HttpRequest newHttpRequest(final String method, final String uri) {
return new BasicHttpRequest(method, uri);
}
};
}
};

看起来你不需要覆盖doService()。您需要为您的方法实现处理程序并确保
handler = this.handlerResolver.lookup(requestURI);
返回你的处理程序。我带你做到了,但由于某种原因,找不到你的处理程序。我打赌你没有正确注册。
