java - httpclient 4 如何获取字节

Question

    HttpGet httpget = new HttpGet("http://www.google.com/"); 

    System.out.println("executing request " + httpget.getURI());

    // Create a response handler
    ResponseHandler<String> responseHandler = new BasicResponseHandler();
    String responseBody = httpclient.execute(httpget, responseHandler);  

这会得到 responseBody 作为“string”，如何用 httpclient.execute(..) 得到 btye[]？我想得到 byte[] 的原因是因为我想写入其他一些输出流

Answer 1

public byte[] executeBinary(URI uri) throws IOException, ClientProtocolException {
    HttpGet httpget = new HttpGet(uri);
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();
    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    entity.writeTo(baos);
    return baos.toByteArray();
}
