Question

我可以单独发送图像和文字，但我想将图像和文本一起发送请帮助我任何人

Answer 1

使用multipart。使用multipart，您可以使用文本数据发送图像视频和其他文件。各种库可用于以多部分发送数据。离子就是其中之一

Answer 2

一种方法是你可以在web api中将图像转换为Base64字符串

First way
 $("#txtQuantity").on('click', function () {
                     alert('testing');
                 });

Second Way
     var recipient = $("#txtQuantity")
             $("#<%=recipient.ClientID%>").on('change', function () {
                alert('testing');
             });

你可以在上面的函数中将位图图像转换为Base64字符串并在api中传递字符串参数并在服务器端解码这些字符串

非常感谢Bhupat Bheda。我完成了我的完整项目。现在我想分享我的研究。

private void saveText() {

    String image= getStringImage(rotatedBMP);
    ImageCapture imageCapture = new ImageCapture();

    imageCapture.Name = prescriptionName.getText().toString();
    imageCapture.Remarks = remarks.getText().toString();
    imageCapture.ImageURL=mCurrentPhotoPath;
    imageCapture.PhotoName=photoName;
    imageCapture.Image=image;

    imageCapture.Id = _ImageId_Id;
    if (_ImageId_Id == 0) {
        restService.getService().InsertPrescription(imageCapture, new Callback<ImageCapture>() {
            @Override
            public void success(ImageCapture imageCapture, Response response) {
                Toast.makeText(Prescription.this, "New Record Inserted.", Toast.LENGTH_LONG).show();

                Intent intent=new Intent(getApplicationContext(),Home.class);
                startActivity(intent);
            }

            @Override
            public void failure(RetrofitError error) {
                Toast.makeText(Prescription.this, error.getMessage().toString(), Toast.LENGTH_LONG).show();

            }
        });
    }

}

private void takePhoto() {
    dispatchTakePictureIntent();
}





@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    Log.i(TAG, "onActivityResult: " + this);
    if (requestCode == REQUEST_TAKE_PHOTO && resultCode == Activity.RESULT_OK) {
        setPic();
    }
}

String mCurrentPhotoPath;
String photoName;

static final int REQUEST_TAKE_PHOTO = 1;
File photoFile = null;

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File

        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    Uri.fromFile(photoFile));
            startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
        }
    }
}



public String getStringImage(Bitmap bmp) {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] imageBytes = baos.toByteArray();
    String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
    return encodedImage;
}
