如何在Python（Flask Framework）中获取JSON对象。以下是我的代码段`

var hotel=$( "#listHotel option:selected" ).val();      
        if(hotel!="select")
        {       
        $.ajax({
            url: '/getHotels',
            data: {'hotel':hotel},          
            type: 'POST',
            success: function(response){
                alert(response);
                var r= JSON.parse(response);                
                var rating =r.message               
                $("#rate").html("Ratings : "+rating);
                $("#rate").show('slow');                
                console.log(response);
            },
            error: function(error){
                alert(response);
                console.log(error);
              }
          });
        }`
