Question

在我的“开始”视图中，我有一些按钮，客户需要选择他们的答案。它得到了一个叫做'＃down;＆＃39;显示他们已经按下了什么。之后他们可以按下一个按钮。它调用一个JQuery函数来获取类向下的按钮，用户ID和问题ID。

在此我调用一个ajax帖子，该帖子转到了值postcontroller到该post方法。

这是JQuery函数：

jQuery(function ($) {
var count = 0;
var answers;
var buttons = new Array();
var id = $(document.getElementsByName('id').valueOf());
var user = $(document.getElementsByName('user').valueOf());

$('#nextBtn').click(function ()
{
    $('.buttons').find('input[type="button"]').each(function ()
    {
        count++;
        buttons.push($(this).valueOf());
    });
    answers.push(id.attr('value'));
    answers.push(user.attr('value'));
    for (var i = 0; i < count; i++)
    {
        if (buttons[i].hasClass('down'))
        {
            answers.push(buttons[i].attr('value'));
        }
    }

    for (var i = 0; i < answers.length; i++) {
        console.log(answers[i]);
    }

       $.ajax({
                url: '/Home/Start/api/Values',
                type: 'POST',
        data: JSON.stringify(answers),
        contentType: "application/json;charset=utf-8",
        succes: function (data) {
            alert("worked!");
        },
        error: function (data) {
            alert("failed!");
        }
       });
    });
});

在valuescontroller中发布方法

 [HttpPost]
    [Route("Home/Start/api/values")]
    public void Post([FromBody]Object[] value)
    {

        convertToAnswer(value);

        //answerLength = _db.Answers.Count();

        //get last id in answers
        answerLength = (from a in _db.Answers
                    select a.Id).Max();

        saveAnswer(value.Length);

        finish(questionId);


      }

在当地一切正常，但现在它是在azure上发布的。我无法在数据库中向表中写入新条目。如果我回到之前填写的问题。它确实有效，我可以在数据库中覆盖它，这也适用于post方法。

这是我在浏览器中获得的错误消息（chrome）

POST http://hostingwebsite/Home/Start/api/Values 500 (Internal Server Error)
n.ajaxTransport.k.cors.a.crossDomain.send @ jquery-2.1.1.min.js:4
n.extend.ajax @ jquery-2.1.1.min.js:4

n.event.dispatch @ jquery-2.1.1.min.js:3
n.event.add.r.handle @ jquery-2.1.1.min.js:3

我希望这是关于我的问题的足够信息，这是我第一次在这里提问。
