httpclient不能访问 HttpURLConnection可以访问

Question

用HttpURLConnection能够把内容打印出来
public static void main(String[] args) {
try{
HttpURLConnection conn = (HttpURLConnection) new URL("http", "www.s1188.com", 80, "/app/member/index.php").openConnection(); BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sbInfo = new StringBuffer();
if(br.ready()){
    String newLine = "\r\n";
    String readInfo = null;
    while((readInfo=br.readLine())!=null) {
        sbInfo.append(readInfo);
        sbInfo.append(newLine);
    }
}
System.out.println("Response message: \r\n" + sbInfo.toString());

}catch(Exception e){
e.printStackTrace();
} }
而用httpclient        HttpClient client = new HttpClient();    
        client.getHostConfiguration().setHost("www.s1188.com", 80, "http");
        client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
        GetMethod authget = new GetMethod(loginurl);
        
        //使用系统提供的默认的恢复策略
        authget.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,new DefaultHttpMethodRetryHandler());
        
        client.executeMethod(authget);
        System.out.println("Login form get: " + authget.getStatusLine().toString()); 
        String tmp = authget.getResponseBodyAsString();
        System.out.println(tmp);
