处理特定网站时,有时我会收到状态码为403的http响应.我想在这种情况下重新执行请求(因为,在我的特定情况下,此服务器在实际超载时会抛出403).我试图和a ResponseHandler一起使用StandardHttpRequestRetryHandler,但它没有按照我希望的方式工作; 我期望在ResponseHandler触发器中抛出异常会触发StandardHttpRequestRetryHandler,但似乎并非如此.如何实现所需的功能？

这是一个示例代码,说明了我的情况:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.client.methods.RequestBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.impl.client.StandardHttpRequestRetryHandler;
import org.apache.http.protocol.HttpContext;
import org.apache.http.util.EntityUtils;


public class Main {

  public static void main(String[] args) throws Exception {

    // a response handler that throws an exception if status is not 200
    ResponseHandler<String> responseHandler = new ResponseHandler<String> () {

      @Override
      public String handleResponse(HttpResponse response) throws
        ClientProtocolException, IOException
      {
        System.out.println("-> Handling response");

        if (response.getStatusLine().getStatusCode() != …
