当我尝试上传大小超过20MB的视频时，服务器无法获取正在发送的任何参数。我发送视频和jsonobject作为字符串到服务器。使用httpmime-4.1.1 jar.Below是我的代码。我是Android开发的新手，任何帮助都会很明显。我需要快速解决方案。请帮帮我
String s = json;
Log.d("message", "s==="+s);
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
StringBuilder sq = null; // Limit
String result = null;
String result1 = null;
try {
HttpPost post = new HttpPost(url);
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
Log.d("message","video"+ bin.getFilename());
reqEntity.addPart("video",bin);
reqEntity.addPart("arguments", new StringBody(s.toString()));
post.setEntity(reqEntity);
int timeoutConnection = 60000;
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters,
timeoutConnection);
int timeoutSocket = 60000;
HttpConnectionParams.setTcpNoDelay(httpParameters, true);
try {
HttpResponse response = client.execute(post);
Log.v("@WebSErvice:"+response, "Result0" + response);
if (response == null) {
result = null;
} else {
try {
TieWebServicesComponents BWSC = new TieWebServicesComponents(
TieWebServicesComponents.POST_TASK, mContext);
result = BWSC.inputStreamToString(response.getEntity()
.getContent());
Log.v("message:CommunityHome Response"+response, "Result1" + result);
} catch (IllegalStateException e) {
// Log.e(TAG, e.getLocalizedMessage(), e);
} catch (IOException e) {
// Log.e(TAG, e.getLocalizedMessage(), e);
}
}
}catch(NullPointerException ne){
}
}
catch(Exception e) {
e.printStackTrace();
}
//Log.v("@WebSErvice:", "REsult" + result);

之前我已经完成了此操作，我已经跟踪了最高可达80mb的内容，并使用MultiPartEntity尝试上传功能。
public class asyncUploadtrack extends AsyncTask<Void, Integer, Void>
{
HttpResponse response;
private android.app.ProgressDialog dialog;
long totalSize;
protected void onPostExecute(String result)
{
}
@Override
protected void onPreExecute()
{
}
@Override
protected void onProgressUpdate(Integer... values)
{
}
protected Void doInBackground(Void... params)
{
Log.i("Do in Backgtound", "Background");
String url =app.WEB_API_URL+"?op="+ Constant.METHOD_UPLOAD_TRACK;
File video = new File(trackPath); // path of file
Bitmap out = Constant.bitmapResize(TrackFragment.btmTrackImg,308, 296) ;//Bitmap.createScaledBitmap(TrackFragment.btmTrackImg, 408, 396,true);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
out.compress(CompressFormat.JPEG, 50, bos);
byte[] data = bos.toByteArray();
HttpClient httpclient = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
try
{
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("music", new FileBody(video));
multipartEntity.addPart("title",new StringBody(trackTitle));
multipartEntity.addPart("user", new StringBody(app.preferences.getStringPref("userId")));
multipartEntity.addPart("filename", new StringBody("song.mp3"));
multipartEntity.addPart("avatar",new ByteArrayBody(data, "trackImage"));
//After adding everything we get the content's lenght
totalSize = multipartEntity.getContentLength();
post.setEntity(multipartEntity);
response = httpclient.execute(post);
try
{
Log.i("Response is",response.getStatusLine().toString());
}
catch (Exception e)
{
e.printStackTrace();
}
}
catch (IOException e)
{
e.printStackTrace();
}
return null;
}
}

检查此代码会对您有所帮助。

String twoHyphens = "--";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"+imagepath);
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"+ imagepath);
}
});
return 0;
}
else
{
try {
// open a URL connection to the Servlet

Video Uploading not working in YII 这个链接帮助了我..代码中没有错误。这是服务器端的问题。
