我能够做一个参数字符串的POST。我用下面的code：

I am able to do a POST of a parameters string. I use the following code:

String parameters = "firstname=john&lastname=doe";
URL url = new URL("http://www.mywebsite.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
connection.setRequestMethod("POST");

OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(parameters);
out.flush();
out.close();
connection.disconnect();

不过，我需要做的二进制数据的POST（这是byte []的形式）。

However, I need to do a POST of binary data (which is in form of byte[]).

不知道如何改变上述code来实现它。 任何人都可以请帮我这个？

Not sure how to change the above code to implement it. Could anyone please help me with this?
