最簡單的例子：

 $.ajax({
        url:"/api/workflow/task!cancelAndAgreeOrDisagreeStep.do",
        dataType: ‘json‘,
        type: ‘post‘,
        data: {
            task_id: task_id
        },
        success: function success(data) {
            //成功後執行的動作
             
        },
        error: function error() {
            //alert(‘獲取信息失敗‘);
        }
    });
