我正在尝试在录制视频时将视频文件上传到服务器。我开始录制和存储在SD卡内时，我将video.mp4设置为视频的默认文件名。录制完成按钮点击事件后，我正在重命名视频名称并尝试将其上传到我的服务器。
但不幸的是我收到了错误。我的应用程序不会停止不幸或任何东西，但当我检查服务器视频文件没有得到更新，在logcat我得到以下错误。

以下是我的java代码。
public class RecordVideo extends Activity {
Button saveVideo;
EditText videoName;
String myFilename = "";
@Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.record_video);
saveVideo = (Button) findViewById(R.id.saveVideo);
videoName = (EditText) findViewById(R.id.videoName);
saveVideo.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
if (videoName.length() <= 0) {
AlertDialog.Builder alert = new AlertDialog.Builder(
RecordVideo.this);
alert.setTitle("Alert");
alert.setMessage("Field can not be set empty")
.setCancelable(false)
.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog, int id) {
dialog.cancel();
}
});
alert.show();
} else {
getFilename();
myFilename = getFilename() + ".mp4";
System.out.println("myFilename===" + myFilename);
doAudioFileUpload(myFilename);
}
}
});
}
public String getFilename() {
String path = Environment.getExternalStorageDirectory()
+ "/filetoupload/video.mp4";
String videoNam = Environment.getExternalStorageDirectory()
+ "/filetoupload/" + videoName.getText().toString().trim();
File file = new File(path);
File file2 = new File(videoNam + ".mp4");
file.renameTo(file2);
Toast.makeText(getApplicationContext(),
"File Renamed and saved successfully", Toast.LENGTH_LONG)
.show();
return videoNam;
}
private void doAudioFileUpload(String path) {
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String existingFileName = path;
System.out.println("Inside of doAudioFileUpload and path is === "
+ path);
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024 * 1024;
String urlString = "server-link/folder-name/upload_video.php";
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
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=\"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(conn.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);
}
}
}
基本上你可以在logcat中看到它在第118行显示错误而我的第118行是dos = new DataOutputStream(conn.getOutputStream());
请帮我解决这个问题。任何帮助，将不胜感激。提前谢谢......

这就是我实现功能的方式。
private void doAudioFileUpload(String path) throws IOException {
String URL = "http://i-qualtech.com/skirr/upload_audio.php";
File file = new File(path);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(URL);
FileBody filebodyVideo = new FileBody(file);
StringBody fName = new StringBody(myFilename);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("videoFile", filebodyVideo);
reqEntity.addPart("filename", fName);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
if (response.getStatusLine().getStatusCode() != 201) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatusLine().getStatusCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(response.getEntity().getContent())));
String output;
while ((output = br.readLine()) != null) {
String out = output;
}
httpclient.getConnectionManager().shutdown();
}
答案 0 :(得分：3)
请尝试使用此代码，它对我有用 -
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(URL);
FileBody filebodyVideo = new FileBody(file);
StringBody fName = new StringBody("Filename: " + filename);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("videoFile", filebodyVideo);
reqEntity.addPart("filename", fName);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute( httppost );
if (response.getStatusLine().getStatusCode() != 201) {
if(response.getStatusLine().getStatusCode() != 200){
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatusLine().getStatusCode());
}
}
BufferedReader br = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));
String output;
while ((output = br.readLine()) != null){
out += output;
Log.i(TAG,"output " + out);
}
httpclient.getConnectionManager( ).shutdown( );
编辑：
使用以下代码使用后台主题上传视频 -
public class MyUploadTask extends AsyncTask<Void, Void, Boolean>{
File file;
String url;
public MyUploadTask(File f,String url){
this.file = f;
this.url = url;
}
@Override
protected Boolean doInBackground(Void... params) {
//call upload video method from here
return false;
}
}
使用doInBackground中的上传视频方法..
