如何从相机到服务器而不是图像选择器上传图像

Question

如何将图像从相机上传到Web服务器，

我可以使用此tuto中的图像选择器进行上传

https://www.simplifiedcoding.net/android-upload-image-to-server/

，但是我想从相机和图库中选择图像

    public void uploadMultipart() {


        //getting the actual path of the image
        String path = getPath(filePath);

        //Uploading code
        try {
            String uploadId = UUID.randomUUID().toString();

            //Creating a multi part request
            new MultipartUploadRequest(this, uploadId, Constants.UPLOAD_URL)
                    .addFileToUpload(path, "image") //Adding file
                    .addParameter("name", name) //Adding text parameter to the request
                    .setNotificationConfig(new UploadNotificationConfig())
                    .setMaxRetries(2)
                    .startUpload(); //Starting the upload

        } catch (Exception exc) {
            Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show();
        }
    }


    //method to show file chooser
    private void showFileChooser() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
    }

    //handling the image chooser activity result
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
            filePath = data.getData();
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
                imageView.setImageBitmap(bitmap);

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

我也找到了这种方法，但是对我不起作用

如何正确替换上面代码中的文件选择器方法以获取图像路径和名称，然后像在tuto中一样将其上传

private void selectImage() {
        final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
        android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(UploadImageTest.this);
        builder.setTitle("Add Photo!");
        builder.setItems(options, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                if (options[item].equals("Take Photo"))
                {
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                    startActivityForResult(intent, 1);
                }
                else if (options[item].equals("Choose from Gallery"))
                {
                    Intent intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                    startActivityForResult(intent, 2);
                }
                else if (options[item].equals("Cancel")) {
                    dialog.dismiss();
                }
            }
        });
        builder.show();
    }

Answer 1

为了将捕获的图像上传到服务器，整个代码保持不变，只需要将捕获的图像文件路径传递到uploadMultipart函数中。

您将在onActivityResult中获得捕获的图像文件路径。
