在Ruby on Rails中旋转图像,类似于AJAX

brew install imagemagick

gem 'mini_magick'

require 'mini_magick'

def rotate_image
  image_path = params[:image_path]
  angle = params[:angle].to_i

  image = MiniMagick::Image.open(image_path)
  image.rotate(angle)
  image.write(image_path)

  render json: { status: 'success' }
end

$("#rotate-button").click(function() {
  var image_path = $("#image_path").val();
  var angle = $("#angle").val();

  $.ajax({
    url: "/rotate_image",
    type: "POST",
    data: { image_path: image_path, angle: angle },
    success: function(response) {
      if (response.status === "success") {
        alert("图像已成功旋转！");
      } else {
        alert("旋转图像时出错！");
      }
    }
  });
});
