如何使用 Android 录制视频并上传到服务器？

Question

我正在制作一个 Android 应用程序，用户将在其中录制一段短视频，当他们完成录制后，视频会自动上传到服务器。我找到了一个完全符合我要求的教程，但使用的是图片而不是视频。我会以同样的方式处理视频吗？或者如何更改教程中的代码以使其用于视频而不是图片？

我已使用以下代码成功将视频从 Android 上传到网络服务器。

请注意，Android 中有多个用于 HTTP 通信的替代库 - 对于视频，您需要确保选择的任何一个（如果您不想使用下面的那个）支持 Multipart 消息。 Android 中 HTTP 的一个很好的概述在这里：https://packetzoom.com/blog/which-android-http-library-to-use.html

public class VideoUploadTask extends AsyncTask<String, String, Integer> {
    /* This Class is an AsynchTask to upload a video to a server on a background thread
     * 
     */

    private VideoUploadTaskListener thisTaskListener;
    private String serverURL;
    private String videoPath;

    public VideoUploadTask(VideoUploadTaskListener ourListener) {
        //Constructor
        Log.d("VideoUploadTask","constructor");

        //Set the listener
        thisTaskListener = ourListener;
    }

    @Override
    protected Integer doInBackground(String... params) {
        //Upload the video in the background
        Log.d("VideoUploadTask","doInBackground");

        //Get the Server URL and the local video path from the parameters
        if (params.length == 2) {
            serverURL = params[0];
            videoPath = params[1];
        } else {
            //One or all of the params are not present - log an error and return
            Log.d("VideoUploadTask doInBackground","One or all of the params are not present");
            return -1;
        }


        //Create a new Multipart HTTP request to upload the video
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(serverURL);

        //Create a Multipart entity and add the parts to it
        try {

            FileBody filebodyVideo = new FileBody(new File(videoPath));
            StringBody title = new StringBody("Filename:" + videoPath);
            StringBody description = new StringBody("Test Video");
            MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            reqEntity.addPart("videoFile", filebodyVideo);
            reqEntity.addPart("title", title);
            reqEntity.addPart("description", description);
            httppost.setEntity(reqEntity);

            //Log the error
            Log.d("VideoUploadTask doInBackground","UnsupportedEncodingException error when setting StringBody for title or description");
            e1.printStackTrace();

        //Send the request to the server
        HttpResponse serverResponse = null;
        try {

            serverResponse = httpclient.execute( httppost );
        } catch (ClientProtocolException e) {
            //Log the error
            Log.d("VideoUploadTask doInBackground","ClientProtocolException");
            e.printStackTrace();
        } catch (IOException e) {
            //Log the error
            Log.d("VideoUploadTask doInBackground","IOException");
            e.printStackTrace();
        }

        //Check the response code
        Log.d("VideoUploadTask doInBackground","Checking the response code");
        if (serverResponse != null) {
            Log.d("VideoUploadTask doInBackground","ServerRespone" + serverResponse.getStatusLine());
            HttpEntity responseEntity = serverResponse.getEntity( );
            if (responseEntity != null) {
                //log the response code and consume the content
                Log.d("VideoUploadTask doInBackground","responseEntity is not null");
                try {
                    responseEntity.consumeContent( );
                } catch (IOException e) {
                    //Log the (further...) error...
                    Log.d("VideoUploadTask doInBackground","IOexception consuming content");
                    e.printStackTrace();
                }
            } 
        } else {
            //Log that response code was null
            Log.d("VideoUploadTask doInBackground","serverResponse = null");
            return -1;
        }

        //Shut down the connection manager
        httpclient.getConnectionManager( ).shutdown( ); 
        return 1;
    }

    @Override
    protected void onPostExecute(Integer result) {
        //Check the return code and update the listener
        Log.d("VideoUploadTask onPostExecute","updating listener after execution");
        thisTaskListener.onUploadFinished(result);
    }

}

This is 在应用程序中实现此功能的更好教程。但是在 API 级别 24 之后现在不允许使用文件// 方案。因此，您需要 look here ,我希望通过这 2 个链接，您可以轻松实现这一点。
