我正在尝试创建一个将mp3文件发送到服务器并将其保存在磁盘中的应用程序。但是我无法找到有关如何执行此操作的信息，我只是发现了此客户端代码，现在我需要实现服务器，我需要使用Play Framework来执行Web服务，任何人都可以帮我一个这样做。
我的客户：
public class Client extends AsyncTask<Void, Void, Void> {
private static final int BUFFER_SIZE = 1 * 1024 * 1024;
private String SongPath;
@Override
protected Void doInBackground(Void... params) {
HttpURLConnection connection = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String existingFileName = SongPath;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String responseFromServer = "";
String urlString = "http://177.105.46.89:9000/uploadSong";
try {
//------------------ CLIENT REQUEST
FileInputStream fileInputStream = new FileInputStream(new File(existingFileName));
// open a URL connection to the Servlet
URL url = new URL(urlString);
// Open a HTTP connection to the URL
connection = (HttpURLConnection) url.openConnection();
// Allow Inputs
connection.setDoInput(true);
// Allow Outputs
connection.setDoOutput(true);
// Don't use a cached copy.
connection.setUseCaches(false);
// Use a post method.
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(connection.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
// dos.writeBytes("Content-Disposition: form-data; name=song" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// close streams
Log.e("Debug", "File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
Log.e("Debug", "error: " + ex.getMessage(), ex);
} catch (IOException ioe) {
Log.e("Debug", "error: " + ioe.getMessage(), ioe);
}
//------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream(connection.getInputStream());
String str;
while ((str = inStream.readLine()) != null) {
Log.e("Debug", "Server Response " + str);
}
inStream.close();
} catch (IOException ioex) {
Log.e("Debug", "error: " + ioex.getMessage(), ioex);
}
return null;
}
public String getSongPath() {
return SongPath;
}
public void setSongPath(String songPath) {
SongPath = songPath;
}
}
