android - 将视频从 Android 上传到服务器？

Question

有人推荐一些将视频从 SD 卡上传到远程服务器的示例吗？

Answer 1

前段时间遇到过同样的问题。这是一个代码。

public static int upLoad2Server(String sourceFileUri) {
  String upLoadServerUri = "your remote server link";
  // String [] string = sourceFileUri;
  String fileName = sourceFileUri;

  HttpURLConnection conn = null;
  DataOutputStream dos = null;
  DataInputStream inStream = null;
  String lineEnd = "\r\n";
  String twoHyphens = "--";
  String boundary = "*****";
  int bytesRead, bytesAvailable, bufferSize;
  byte[] buffer;
  int maxBufferSize = 1 * 1024 * 1024;
  String responseFromServer = "";

  File sourceFile = new File(sourceFileUri);
  if (!sourceFile.isFile()) {
   Log.e("Huzza", "Source File Does not exist");
   return 0;
  }
  try { // open a URL connection to the Servlet
   FileInputStream fileInputStream = new FileInputStream(sourceFile);
   URL url = new URL(upLoadServerUri);
   conn = (HttpURLConnection) url.openConnection(); // Open a HTTP  connection to  the URL
   conn.setDoInput(true); // Allow Inputs
   conn.setDoOutput(true); // Allow Outputs
   conn.setUseCaches(false); // Don't use a Cached Copy
   conn.setRequestMethod("POST");
   conn.setRequestProperty("Connection", "Keep-Alive");
   conn.setRequestProperty("ENCTYPE", "multipart/form-data");
   conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
   conn.setRequestProperty("uploaded_file", fileName);
   dos = new DataOutputStream(conn.getOutputStream());

   dos.writeBytes(twoHyphens + boundary + lineEnd);
   dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ fileName + "\"" + lineEnd);
   dos.writeBytes(lineEnd);

   bytesAvailable = fileInputStream.available(); // create a buffer of  maximum size
   Log.i("Huzza", "Initial .available : " + bytesAvailable);

   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);

   // Responses from the server (code and message)
   serverResponseCode = conn.getResponseCode();
   String serverResponseMessage = conn.getResponseMessage();

   Log.i("Upload file to server", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode);
   // close streams
   Log.i("Upload file to server", fileName + " File is written");
   fileInputStream.close();
   dos.flush();
   dos.close();
  } catch (MalformedURLException ex) {
   ex.printStackTrace();
   Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
  } catch (Exception e) {
   e.printStackTrace();
  }
//this block will give the response of upload link
  try {
   BufferedReader rd = new BufferedReader(new InputStreamReader(conn
     .getInputStream()));
   String line;
   while ((line = rd.readLine()) != null) {
    Log.i("Huzza", "RES Message: " + line);
   }
   rd.close();
  } catch (IOException ioex) {
   Log.e("Huzza", "error: " + ioex.getMessage(), ioex);
  }
  return serverResponseCode;  // like 200 (Ok)

 } // end upLoad2Server

2) 用

调用它

int reponse=upLoad2Server(""+filepath);
