HttpComponents在調用HttpResponse時凍結response2 = conn.receiveResponseHeader（）;

Question

我正在嘗試一些基本的東西HttpComponents。

我收到一個奇怪的問題conn.receiveResponseHeader();。也許我沒有正確使用它，但我看不到它是什麼。

當程序到達這一行時，它會無限期地暫停。當我調試，並評估表達它永遠說「（待定）」。

public class Test2 { 

    public static void main(String[] args) throws IOException, HttpException { 

     Socket socket = new Socket("www.booya.com", 80); 
     DefaultBHttpClientConnection conn = new DefaultBHttpClientConnection(8 * 1024); 
     HttpRequest request2 = new BasicHttpRequest("GET", "/"); 
     conn.bind(socket); 
     conn.sendRequestHeader(request2); 
     HttpResponse response2 = conn.receiveResponseHeader(); 
     System.out.println(response2.getAllHeaders()); 
     System.out.println(conn.isOpen()); 
     HttpConnectionMetrics metrics = conn.getMetrics(); 
     System.out.println(metrics.getRequestCount()); 
     System.out.println(metrics.getResponseCount()); 
     System.out.println(metrics.getReceivedBytesCount()); 
     System.out.println(metrics.getSentBytesCount()); 
     conn.close(); 

    } 

}

不要忘了刷新內部會話緩衝

conn.bind(socket); 
conn.sendRequestHeader(request2); 
conn.flush();
