如何重新创建html请求标头?

我正在编写一个远程控制我的Roku的Java应用程序。我找到了this网站并用它来控制我的Roku。从Chromes开发人员工具中,我观察了其数据流量,并找到了控制Roku的html请求。标题是这个。

POST /keydown/Play HTTP/1.1
Host: 192.xxx.x.82:8060
Connection: keep-alive
Content-Length: 0
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Origin: http://remoku.tv
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36
Content-Type: application/x-www-form-urlencoded
Referer: http://remoku.tv/
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.8

然后我尝试在Java中重新创建这个POST请求,结果看起来像这样:

HttpURLConnection urlConn;
URL url = new URL("html://192.xxx.x.82:8060/keydown/Play");
urlConn = (HttpURLConnection) url.openConnection();

urlConn.setRequestProperty("Connection", "keep-alive");
urlConn.setRequestProperty("Content-Length", "0");
urlConn.setRequestProperty("Cache-Control", "max-age=0");
urlConn.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
urlConn.setRequestProperty("Origin", "http://192.xxx.x.254");
urlConn.setRequestProperty("Upgrade-Insecure-Requests", "1");
urlConn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36");
urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
urlConn.setRequestProperty("Referer", "http://192.xxx.x.254");
urlConn.setRequestProperty("Accept-Encoding", "gzip, deflate");
urlConn.setRequestProperty("Accept-Language", "en-US,en;q=0.8");

我不是100%确定这是重新创建请求的正确方法,因为它与原始(工作)没有相同的效果。但是,这可能是因为我改变了一些可能实际上很重要的细节。所以我的问题是,如果这是重新创建请求的正确方法,如果这是为什么它不起作用?如果不是什么?任何帮助表示赞赏。

感谢tgkprog的评论我编辑了我的代码:

HttpURLConnection urlConn;
URL url = new URL("http://192.xxx.x.82:8060/keypress/Right");
urlConn = (HttpURLConnection) url.openConnection();
urlConn.setRequestMethod("POST");
urlConn.setDoOutput(true);

try(DataOutputStream wr = new DataOutputStream(urlConn.getOutputStream())) {
             wr.writeChars("");
}

System.out.println(urlConn.getResponseCode());

现在它完美无缺,我可以控制我的Roku问题是我没有在标题中使用正确的键,因为它们没有在Chrome中锁定大写(编辑:它们不是必需的)。
