如何從Apache httpclient錯誤獲取html內容？

Question

我在java中使用Apache http客戶端，但我注意到它拒絕在非200結果中獲取內容......我如何覆蓋它？

我已經試過這樣：

import org.apache.commons.httpclient.*; 
import org.apache.commons.httpclient.methods.*; 
import org.apache.commons.httpclient.params.HttpMethodParams; 

import java.io.*; 

public class HttpClientTutorial { 

    private static String url = "http://www.apache.org/"; 

    public static void main(String[] args) { 
    // Create an instance of HttpClient. 
    HttpClient client = new HttpClient(); 

    // Create a method instance. 
    GetMethod method = new GetMethod(url); 

    // Provide custom retry handler is necessary 
    method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, 
      new DefaultHttpMethodRetryHandler(3, false)); 

    try { 
     // Execute the method. 
     int statusCode = client.executeMethod(method); 

     if (statusCode != HttpStatus.SC_OK) { 
     System.err.println("Method failed: " + method.getStatusLine()); 
     } 

     // Read the response body. 
     byte[] responseBody = method.getResponseBody(); 

     // Deal with the response. 
     // Use caution: ensure correct character encoding and is not binary data 
     System.out.println(new String(responseBody)); 

    } catch (HttpException e) { 
     System.err.println("Fatal protocol violation: " + e.getMessage()); 
     e.printStackTrace(); 
    } catch (IOException e) { 
     System.err.println("Fatal transport error: " + e.getMessage()); 
     e.printStackTrace(); 
    } finally { 
     // Release the connection. 
     method.releaseConnection(); 
    } 
    } 
} 

在200和404

，它按預期工作（錯誤代碼+內容）。代碼來自apache網站本身：http://hc.apache.org/httpclient-3.x/tutorial.html
