Android Studio错误Okhttp3单击按钮后未上传音频文件

Question

你好昨天我看到一个使用 okhtpp3 上传文件到服务器的教程 (https://www.youtube.com/watch?v=K48jnbM8yS4) 我按照教程进行操作，它运行良好，但现在我正在尝试开发一个应用程序，它有一个录制按钮来录制音频并保存到内部存储和另一个按钮来上传音频文件。

但它没有上传文件。

我的应用代码：

        public class MainActivity extends AppCompatActivity{


        private String n="";

        private Button mRecordBtn,uploadBtn;
        private TextView mRecordLabel;
        private MediaRecorder mRecorder;

        private String mFileName = null;
        private static final String LOG_TAG = "Record_log";

        final int REQUEST_PERMISSION_CODE =1000;

        private ProgressDialog progress;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);


            if(!checkPermissionFromDevice()){
                requestPermission();

            }

            mRecordLabel =(TextView) findViewById(R.id.recordLbl);
            mRecordBtn =(Button)findViewById(R.id.recordBtn);


            mFileName = Environment.getExternalStorageDirectory() + "/file.3gp";



            mRecordBtn.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {

                    if (checkPermissionFromDevice()) {




                    if (event.getAction() == MotionEvent.ACTION_DOWN) {
                        startRecording();
                        mRecordLabel.setText("Recording Started...");

                    } else if (event.getAction() == MotionEvent.ACTION_UP) {

                        stopRecording();
                        mRecordLabel.setText("Recording Stoped...");
                    }

                }
                else{
                        requestPermission();
                    }
                    return false;
                }
            });


                uploadBtn =(Button)findViewById(R.id.uplaodBtn);
                uploadBtn.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        sendFile();

                    }
                });


        }

        private void startRecording() {
            mRecorder = new MediaRecorder();
            mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
            mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
            mRecorder.setOutputFile(mFileName);
            mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);


            try {
                mRecorder.prepare();
            } catch (IOException e) {
                Log.e(LOG_TAG, "prepare() failed");
            }

            mRecorder.start();
        }

        private void stopRecording() {
            mRecorder.stop();
            mRecorder.release();
            mRecorder = null;





        }

        private void requestPermission(){

            ActivityCompat.requestPermissions(this,new String[]{

                    Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    Manifest.permission.RECORD_AUDIO,
                    Manifest.permission.READ_EXTERNAL_STORAGE
            },REQUEST_PERMISSION_CODE);
        }

        @Override
        public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
            switch(requestCode) {
                case REQUEST_PERMISSION_CODE: {
                    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
                        Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
                    else{
                        Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show();
                    }

                }


                break;
            }


        }

        private boolean checkPermissionFromDevice(){

            int write_internal_storage_result = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
            int record_audio_result =ContextCompat.checkSelfPermission(this,Manifest.permission.RECORD_AUDIO);
            int read_internal_storage_result =ContextCompat.checkSelfPermission(this,Manifest.permission.READ_EXTERNAL_STORAGE);

            return  write_internal_storage_result == PackageManager.PERMISSION_GRANTED && record_audio_result == PackageManager.PERMISSION_GRANTED && read_internal_storage_result == PackageManager.PERMISSION_GRANTED;


        }



        private void sendFile() {



            OkHttpClient client = new OkHttpClient();
            File f = new File(mFileName);
            String content_type  = getMimeType(f.getPath());
            String file_path = f.getAbsolutePath();

            RequestBody file_body = RequestBody.create(MediaType.parse(content_type),f);
            RequestBody requestBody = new MultipartBody.Builder()
                    .setType(MultipartBody.FORM)
                    .addFormDataPart("title", content_type)
                    .addFormDataPart("uploaded_file",file_path.substring(file_path.lastIndexOf("/")+1), file_body)
                    .build();

            Request request = new Request.Builder()
                    .url("http://192.168.8.100/etrack/save_audio.php")
                    .post(requestBody)
                    .build();

            client.newCall(request).enqueue(new Callback() {
                @Override
                public void onFailure(Call call, IOException e) {
    //                Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_LONG).show();
                }

                @Override
                public void onResponse(Call call, final Response response) throws IOException {
    //                if (!response.isSuccessful()) {
    //                    Toast.makeText(MainActivity.this, "Response error", Toast.LENGTH_LONG).show();
    //                }
                }
            });
        }

    private String getMimeType(String path){

        String extension = MimeTypeMap.getFileExtensionFromUrl(path);
        return MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);


    }
}

这是我的 php 代码：

    <?php

$file_path = "images/";

$file_path = $file_path . basename($_FILES['uploaded_file']['name']);

if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$file_path)) {
    echo "success";
}else {
    echo "error";
}

?>

我的构建：gradle 代码：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    defaultConfig {
        applicationId "www.teamruby.com.samplerecord"

Answer 1

File f = new File(mFileName);
MultipartBody.Builder data = new MultipartBody.Builder();
                data.setType(MultipartBody.FORM);
                data.addFormDataPart("uploaded_file", "file.3gp", RequestBody.create(MediaType.parse("media/type"), f));
                RequestBody requestBody = data.build();

                Request request = new Request.Builder()
                        .url("192.168.8.100/etrack/save_audio.php").post(requestBody)
                        .build();
