使用 JAVA/Android 和 Http 的 Chromecast 通信
Chromecast communication using JAVA/Android and Http
我正在尝试使用 Http 与 Chromecast 通信。我正在使用 this documentation about API methods and trying to execute an Youtube video on it. Following this 答案来执行 post 调用,现在我有:
@Override
public void run() {
try {
String urlParameters = "v=oHg5SJYRHA0";
byte[] postData = urlParameters.getBytes();
int postLenght = postData.length;
//url is: new URL("http://192.168.25.99:8008/apps/YouTube")
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setInstanceFollowRedirects(true);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.setRequestProperty("Content-Length", Integer.toString(postLenght));
urlConnection.setUseCaches(false);
DataOutputStream wr = new DataOutputStream(urlConnection.getOutputStream());
wr.write(postData);
wr.flush();
wr.close();
} catch (IOException e) {
e.printStackTrace();
}
}
此命令正确执行,但在 Chromecast 中没有任何反应。
我做错了什么?
有效,我只是忘了调用响应:
String responseMessage = urlConnection.getResponseMessage();
当我调用这个方法时,视频就会执行。
