Javascript 使用响应JSON.parse

我的错误是：

Uncaught SyntaxError: Unexpected token H in JSON at position 0

我试图在laravel 5.3中制作一个日历，但是控制台中出现了这个错误，有一个json响应，在json和javascript中我是新的，日历就是一个例子，我正在尝试修改laravel。如果出现此错误，则在本部分中：

$('#calendar').fullCalendar({
        events: JSON.parse(json_events),
        //events: [{"id":"14","title":"New Event","start":"2015-01-24T16:00:00+04:00","allDay":false}],
        utc: true,
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month,agendaWeek,agendaDay'
        },

如果有人能给我一个严肃的回复或者很多帮助，我是javascript的新手，请查看您的开发者控制台/网络选项卡以查看实际的响应。然后复制并验证它。我很确定服务器的响应不是您想象的那样。

您能显示实际的AJAX响应吗。您似乎没有获得有效的JSON。这些行是问题的根源

success:function（response）{event.id=response.eventid；

…可能来自url的响应不是有效的ajax响应这不是真正的答案。最好将其添加为注释。答案是我期望的答案托马斯，你能显示响应吗？它是有效的JSON吗？斯科特，我没有足够的声誉来评论。
