如何从摄像头采集图像并上传到Retrofit multipart？

// 1. 添加摄像头权限及逻辑处理

// 2. 打开摄像头并预览图像
Camera camera = Camera.open();
SurfaceTexture surfaceTexture = new SurfaceTexture(0);
camera.setPreviewTexture(surfaceTexture);
camera.startPreview();

// 3. 获取摄像头预览帧并转换为Bitmap
camera.setPreviewCallback(new Camera.PreviewCallback() {
    @Override
    public void onPreviewFrame(byte[] data, Camera camera) {
        Camera.Size size = camera.getParameters().getPreviewSize();
        YuvImage image = new YuvImage(data, ImageFormat.NV21, size.width, size.height, null);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        image.compressToJpeg(new Rect(0, 0, size.width, size.height), 80, stream);
        byte[] jpegData = stream.toByteArray();
        Bitmap bitmap = BitmapFactory.decodeByteArray(jpegData, 0, jpegData.length);

        // 4. 创建Retrofit接口
        Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("https://example.com/api/")
            .build();
        ImageUploadService service = retrofit.create(ImageUploadService.class);

        // 5. 将Bitmap转换为字节数组
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
        byte[] imageBytes = outputStream.toByteArray();

        // 6. 创建multipart请求体
        RequestBody requestBody = new MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("image", "image.jpg", RequestBody.create(MediaType.parse("image/jpeg"), imageBytes))
            .build();

        // 7. 发起网络请求
        Call<ResponseBody> call = service.uploadImage(requestBody);
        call.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                // 处理上传成功的响应
            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                // 处理上传失败的响应
            }
        });
    }
});

// Retrofit接口定义
interface ImageUploadService {
    @POST("upload")
    Call<ResponseBody> uploadImage(@Body RequestBody image);
}
