Question

在我的应用程序中，我需要以较小的尺寸录制音频或视频，并需要将其保存到媒体并发送到服务器。这样做的最佳方法是什么？不使用任何第三方库。请指导我。谢谢。

Answer 1

最好的方法是在服务器上创建API，然后将参数传递给该API。主要功能将由API执行。

Answer 2

将文件发送到服务器，您需要一个上传URL和录音的文件名，这里是代码

代码说明

打开网址连接，获取要写入数据的信息流。
指定一个包含流信息的最大缓冲区。

3.从文件中读取字节并将其写入输出流。

4.获得回复并相应地采取必要的行动。

public boolean uploadFileNew(String sourceFileUri) {
        HttpURLConnection connection = null;
        DataOutputStream outputStream = null;
        DataInputStream inputStream = null;

        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";

        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1 * 1024 * 1024;
        File upFile=null;       

        try {
            final File root = new File((Environment.getExternalStorageDirectory() + File.separator + "DIR_NAME"));


            root.mkdirs();
            final String tmp[] = sourceFileUri.split(File.separator);
            final String fname = tmp[tmp.length-1];
            upFile = new File(root, fname);



                FileInputStream fileInputStream = new FileInputStream(upFile);


                URL url = new URL("YOUR_URL");
                connection = (HttpURLConnection) url.openConnection();

                // Allow Inputs & Outputs.
                connection.setDoInput(true);
                connection.setDoOutput(true);
                connection.setUseCaches(false);

                // Set HTTP method to POST.
                connection.setReadTimeout(10000);
                connection.setConnectTimeout(15000);
                connection.setRequestMethod("POST");

                connection.setRequestProperty("Connection", "Keep-Alive");

                connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);

                outputStream = new DataOutputStream(connection.getOutputStream());
                outputStream.writeBytes(twoHyphens + boundary + lineEnd);

                outputStream.writeBytes("Content-Disposition: form-data; typ=\""+1+"\"; name=\""+fname+"\";filename=\"" + fname + "\"" + lineEnd);
                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();
                InputStream in = connection.getInputStream();

                byte data[] = new byte[1024];
                int counter = -1;

                in.close();


                if (serverResponseCode == 200) {
                    Log.d("uploadFile", "File Upload Complete.");
                }

                fileInputStream.close();
                outputStream.flush();
                outputStream.close();

            }
        } catch (Exception ex) {
            Log.d("uploadFile", "File Upload Error:" + ex.toString());

            return false;

        }


        return true;
    }
