php - 从android上传大视频文件到服务器

Question

我知道如何从 android 上传文件，我可以使用以下代码来完成

private void doFileUpload(MessageModel model) {
    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;// 1 MB
    String responseFromServer = "";

    String imageName = null;
    try {
        // ------------------ CLIENT REQUEST
        File file = new File(model.getMessage());
        FileInputStream fileInputStream = new FileInputStream(file);
        AppLog.Log(TAG, "File Name :: " + file.getName());
        String[] temp = file.getName().split("\\.");
        AppLog.Log(TAG, "temp array ::" + temp);
        String extension = temp[temp.length - 1];
        imageName = model.getUserID() + "_" + System.currentTimeMillis()
                + "." + extension;

        // open a URL connection to the Servlet
        URL url = new URL(Urls.UPLOAD_VIDEO);
        // Open a HTTP connection to the URL
        conn = (HttpURLConnection) url.openConnection();
        // Allow Inputs
        conn.setDoInput(true);
        // Allow Outputs
        conn.setDoOutput(true);
        // Don't use a cached copy.
        conn.setUseCaches(false);
        // Use a post method.
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.setRequestProperty("Content-Type",
                "multipart/form-data;boundary=" + boundary);
        dos = new DataOutputStream(conn.getOutputStream());
        dos.writeBytes(twoHyphens + boundary + lineEnd);
        dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
                + imageName + "\"" + lineEnd);
        Log.i(TAG, "Uploading starts");
        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) {
            // Log.i(TAG, "Uploading");
            dos.write(buffer, 0, bufferSize);
            bytesAvailable = fileInputStream.available();
            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            AppLog.Log(TAG, "Uploading Vedio :: " + imageName);
        }
        // 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");
        Log.i(TAG, "Uploading ends");
        fileInputStream.close();
        dos.flush();
        dos.close();
    } catch (MalformedURLException ex) {
        ex.printStackTrace();
        Log.e("Debug", "error: " + ex.getMessage(), ex);
    } catch (IOException ioe) {
        ioe.printStackTrace();
        Log.e("Debug", "error: " + ioe.getMessage(), ioe);
    }
    // ------------------ read the SERVER RESPONSE ----------------
    try {
        inStream = new DataInputStream(conn.getInputStream());
        String str;

        while ((str = inStream.readLine()) != null) {
            Log.e("Debug", "Server Response " + str);
            try {
                final JSONObject jsonObject = new JSONObject(str);
                if (jsonObject.getBoolean("success")) {
                    handler.post(new Runnable() {
                        public void run() {
                            try {
                                Toast.makeText(getApplicationContext(),
                                        jsonObject.getString("message"),
                                        Toast.LENGTH_SHORT).show();
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }

                        }
                    });
                } else {
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            try {
                                Toast.makeText(getApplicationContext(),
                                        jsonObject.getString("message"),
                                        Toast.LENGTH_SHORT).show();
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                    });
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }

        }
        model.setMessage(imageName);
        onUploadComplete(model);
        inStream.close();

    } catch (IOException ioex) {
        ioex.printStackTrace();
        Log.e("Debug", "error: " + ioex.getMessage(), ioex);
    }
    manageQueue();
}

该代码非常适合短视频，但无法上传大文件，我也不知道为什么。:(

我知道只问为什么我的代码不起作用是一种不好的做法，但在这里我要问的是为什么代码对于大文件的行为不同。

我还在 StackOverFlow 上检查了其他答案，但没有发现我的代码有任何缺陷。

谢谢

你可以试试HttpClient jar下载最新的 HttpClient jar，将其添加到您的项目中，然后使用以下方法上传视频:

    private void uploadVideo(String videoPath) throws ParseException, IOException {

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(YOUR_URL);

FileBody filebodyVideo = new FileBody(new File(videoPath));
StringBody title = new StringBody("Filename: " + videoPath);
StringBody description = new StringBody("This is a video of the agent");
StringBody code = new StringBody(realtorCodeStr);

MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("videoFile", filebodyVideo);
reqEntity.addPart("title", title);
reqEntity.addPart("description", description);
reqEntity.addPart("code", code);
httppost.setEntity(reqEntity);

// DEBUG
System.out.println( "executing request " + httppost.getRequestLine( ) );
HttpResponse response = httpclient.execute( httppost );
HttpEntity resEntity = response.getEntity( );

// DEBUG
System.out.println( response.getStatusLine( ) );
if (resEntity != null) {
  System.out.println( EntityUtils.toString( resEntity ) );
} // end if

if (resEntity != null) {
  resEntity.consumeContent( );
} // end if

httpclient.getConnectionManager( ).shutdown( );
    } // end of uploadVideo( )
