httpclient 4 how to get bytes

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);

this will get responseBody as "string" , how to get btye[] with httpclient.execute(..) ? the reason i want to get byte[] is because i want to write to some other outputstream

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();
}

Is it fine to leave baos not closed over here, or we need to explicitly close it by baos.close() ? – insanely_sin Mar 28 '17 at 18:20

You can use the responseBody.getBytes() to get byte[].

this appears to create a characterset conversion issue – Alex R Mar 31 '15 at 14:22

Try HttpResponse.getEntity().writeTo(OutputStream)
