我正在尝试使用多种方法将视频文件从Android手机上传到服务器。他们似乎都没有像现在一样工作。
首先，我尝试使用正常的多部分上传，我上传图像并运行良好。
代码段
public int uploadFileVideo(String sourceFileUri) {
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(GcmActivity.this, "File not found", Toast.LENGTH_LONG).show();
}
});
return 0;
}
else
{
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL("http://example.com/ccs-business/upload.php");
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setChunkedStreamingMode(0);
conn.setUseCaches(false);
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_video", 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("Content-Disposition: form-data; name=\"uploaded_video\";filename=\"" + fileName +"\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
/* bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize); */
//bufferSize = Math.min(bytesAvailable, maxBufferSize);
//buffer = new byte[bufferSize];
//byte byt[]=new byte[bufferSize];
byte[] buf = new byte[ 4096 ];
int read = 0;
while( ( read = fileInputStream.read( buf ) ) != -1 ) {
dos.write( buf, 0, read );
}
// 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("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(GcmActivity.this, "File Upload Complete.",
Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
}
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
dialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(GcmActivity.this, "MalformedURLException",
Toast.LENGTH_SHORT).show();
}
});
Log.v("ONMESSAGE", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
dialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(GcmActivity.this, "This file can not be uploaded ",
Toast.LENGTH_SHORT).show();
}
});
Log.v("ONMESSAGE", "Exception : " + e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
} // End else block
}
它不起作用，所以我尝试了下一个程序
代码段
public void uploadWithHttpClient(String uri)
{
File myFile = new File(uri);
try{
AsyncHttpClient client = new AsyncHttpClient();
RequestParams params = new RequestParams();
params.put("uploaded_video", myFile);
client.post(this, "http://example.com/ccs-business/upload.php", params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
dialog.dismiss();
Log.v("ONMESSAGE", "Success");
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
Log.v("ONMESSAGE", "Failure");
dialog.dismiss();
}
});
}
catch(Exception e)
{
dialog.dismiss();
Log.v("ONMESSAGE", "Exception is " + e.toString());
}
}
然后我写了一个扩展 MultipartEntity 的类然后在我尝试上传的AsyncTask中。有些文件上传，有些则没有。
代码段
public class CustomMultiPartEntity extends MultipartEntity
{
private final ProgressListener listener;
public CustomMultiPartEntity(final ProgressListener listener)
{
super();
this.listener = listener;
}
public CustomMultiPartEntity(final HttpMultipartMode mode, final ProgressListener listener)
{
super(mode);
this.listener = listener;
}
public CustomMultiPartEntity(HttpMultipartMode mode, final String boundary, final Charset charset, final ProgressListener listener)
{
super(mode, boundary, charset);
this.listener = listener;
}
@Override
public void writeTo(final OutputStream outstream) throws IOException
{
super.writeTo(new CountingOutputStream(outstream, this.listener));
}
public static interface ProgressListener
{
void transferred(long num);
}
public static class CountingOutputStream extends FilterOutputStream
{
private final ProgressListener listener;
private long transferred;
public CountingOutputStream(final OutputStream out, final ProgressListener listener)
{
super(out);
this.listener = listener;
this.transferred = 0;
}
public void write(byte[] b, int off, int len) throws IOException
{
out.write(b, off, len);
this.transferred += len;
this.listener.transferred(this.transferred);
}
public void write(int b) throws IOException
{
out.write(b);
this.transferred++;
this.listener.transferred(this.transferred);
}
}
}
AysncTask CLass
private class HttpMultipartPost extends AsyncTask<String, Integer, String>
{
ProgressDialog pd;
long totalSize;
@Override
protected void onPreExecute()
{
pd = new ProgressDialog(GcmActivity.this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setMessage("Uploading Video...");
pd.setCancelable(false);
pd.show();
}
@Override
protected String doInBackground(String... arg0)
{
HttpClient httpClient = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost("http://example.com/ccs-business/upload.php");
try
{
CustomMultiPartEntity multipartContent = new CustomMultiPartEntity(new ProgressListener()
{
@Override
public void transferred(long num)
{
publishProgress((int) ((num / (float) totalSize) * 100));
}
});
// We use FileBody to transfer an image
multipartContent.addPart("uploaded_video", new FileBody(new File(pathOfpictoUpload)));
//multipartContent.addPart(name, contentBody)d
totalSize = multipartContent.getContentLength();
// Send it
httpPost.setEntity(multipartContent);
HttpResponse response = httpClient.execute(httpPost, httpContext);
String serverResponse = EntityUtils.toString(response.getEntity());
return serverResponse;
}
catch (Exception e)
{
System.out.println(e);
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress)
{
pd.setProgress((int) (progress[0]));
}
@Override
protected void onPostExecute(String ui)
{
pd.dismiss();
Log.v("ONMESSAGE", "SERVER RESPONSE IS " + ui);
}
}
