好的伙计这是我的最后一招，我正在尝试发送一个视频文件保存在服务器上，但不知道如何这样做。这是我到目前为止用于发布帖子请求的代码：
private class DownloadWebpageTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... urls) {
HttpURLConnection conn = null;
BufferedReader reader = null;
try{
String query = urls[0];
URL url = new URL(getData);
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
Writer writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(query);
writer.flush();
writer.close();
conn.connect();
InputStream is = conn.getInputStream();
reader = new BufferedReader(new InputStreamReader(is));
StringBuffer sb = new StringBuffer();
String line = "";
while((line = reader.readLine()) != null){
sb.append(line);
}
return sb.toString();
}catch (MalformedURLException e){
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result){
try{
JSONObject results = new JSONObject(result);
JSONArray jr = results.getJSONArray("info");
....................
}catch(JSONException e){
e.printStackTrace();
}
}
}
请你帮我定制这个脚本来发送一个大的mp4文件，如果可能的话加上它的php对应物。我在网上发现了一些类似问题的在线脚本，但它对我不起作用而是在这里给出了一个outOfMemory异常
private class VidUploadWebpageTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... urls) {
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
File cheak = new File(Environment.getExternalStorageDirectory().getPath() + "/Movies/ReallyChat/Lamlam.mp4");
String pathOfYourFile = "android.resource://" + getPackageName() + "/" + R.raw.countdown;
String urlServer = "http://www.gogodis.comxa.com/vid.php?";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
BufferedReader reader = null;
try{

URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();
// Allow Inputs & Outputs

outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathOfYourFile );
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// Read file
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while(bytesRead > 0){
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
int serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
Log.d("ServerCode", "" + serverResponseCode);
Log.d("serverResponseMessage",""+serverResponseMessage);
fileInputStream.close();
outputStream.flush();
outputStream.close();
}
catch(Exception ex){
ex.printStackTrace();
}
return null;
}
@Override

System.out.println("ok "+result);
try{

非常感谢你，我知道这很多，但我很绝望
答案 0 :(得分：0)
我建议你使用Koush / Ion库。
用这个我轻松实现上传图片到服务器，视频应该不会有很大差异你应该做多部分/文件请求
Ion.with(YourActivity.this)
.load(getString(R.string.uploadURL))
.uploadProgressHandler(new ProgressCallback() {
@Override
public void onProgress(long uploaded, long total) {
// Displays the progress bar for the first time.
}
})
.addHeader("Authorization","bearer "+bearer)
.setTimeout(60 * 60 * 1000)
.setMultipartFile("upload", "image/jpeg", file)
.asJsonObject()
// run a callback on completion
.setCallback(new FutureCallback<JsonObject>() {
@Override
public void onCompleted(Exception e, JsonObject result) {
// When the loop is finished, updates the notification
if (e != null) {
Log.d("ImageUpload",result.toString());
Toast.makeText(CreateViolation.this, "Error uploading file", Toast.LENGTH_LONG).show();
return;
}
imageURL =result.get("files").getAsJsonArray().get(0).getAsJsonObject().get("url").getAsString();
Toast.makeText(CreateViolation.this, "File upload complete", Toast.LENGTH_LONG).show();
}
});

尝试使用此 Link上传图片以及视频到服务器。你也可以得到PHP代码......
