我正在尝试使用mime.MultipartEntityBuilder上传视频文件,但我在logcat中收到以下错误

这是我的代码库:
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.util.EntityUtils;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import android.os.AsyncTask;
import android.util.Log;
public class UploadVideoAsync extends AsyncTask<String, String, Object[]> {
@Override
protected Object[] doInBackground(String... params) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(params[0].toString());
final File video = new File(params[1].toString());
//String video = params[1].toString();
ContentBody cb = new FileBody(video);
try{
MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
//entityBuilder.addPart("video", cb);
entityBuilder.addBinaryBody("video", video);
entityBuilder.addTextBody("sid", params[2].toString());
HttpEntity entity = entityBuilder.build();
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
HttpEntity httpEntity = response.getEntity();
Log.v("result", EntityUtils.toString(httpEntity));
return new Object[]{response, new BasicResponseHandler().handleResponse(response)};
}catch (ClientProtocolException e) {
e.printStackTrace();
}
return new Object[0];
}
}
我无法找到确切的问题。有人能说出代码有什么问题吗?
