与后向服务器发送解析JSON - 为什么会发生这种Ajax调用失败？ [英] Sending JSON with a POST to server for parsing - why does this ajax call fail?

问题描述

所以，我送一个JSON字符串到我的服务器通过jQuery的AJAX解析。我从glosbe字典的API的JSON。它的大部分工作正常，但也有失败的某些JSONs的时间。有趣的是，在这些情况下，我得到一个内部服务器错误，但是当我试图调试应用程序，这似乎是控制器甚至没有叫。我不知道怎么说甚至有可能。

下面是我的看法：

  $。阿贾克斯（{
        网址：@ Url.Action（解析，GetMeaning），
        数据类型：JSON，
        数据：ValueToParse =+ jsonToSend，//也许是更好地发送一个字符串的JSON而不是
        键入：POST，
        异步：假的，
        的contentType：应用/ JSON的;字符集= UTF-8，
        成功：功能（数据）{
            //将数据传递到服务器进行解析

            //警报（sendJsonToServer成功sended+ JSON.stringify（json1）+回来：+数据）;
            setMeaningofEx pression（如pression，数据）;
            $（'＃EX pressionTranslations）HTML（如pressionsAsString（））。
        }，
        错误：函数（XHR，状态，错误）{
            警报（'sendJsonToServer错误，试图向其发送+ JSON.stringify（jsonToSend）+'的问题：+状态++误差）;
        }
    }）;
 

控制器：

  [HttpPost]
    公共JsonResult解析（字符串ValueToParse）
    {

            返回JSON（Parser.Parse（ValueToParse）.ToArray（））;

    }
 

这是失败的一个例子的Json：

解决方案

但问题是，ASP.NET阻止JSON的，因为它认为这是因为存在安全隐患的＆LT; B＆GT;＆LT; / B＆GT; 标签

So, I send a JSON string to my server for parsing via jQuery ajax. I get the JSON from the Glosbe dictionary's API. Most of the time it works as expected, but there are certain JSONs that fail. What is interesting is that in those cases I get an "Internal server error", but when I tried to debug the application, it seemed like the controller wasn't even called. I don't know how that's even possible.

Here's my View:

        $.ajax({
        url: '@Url.Action("Parse", "GetMeaning")',
        dataType: "json",
        data: "ValueToParse=" + jsonToSend, //maybe it's better to send a json instead of a string
        type: 'POST',
        async: false,
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            //pass the data to the server for parsing

            //alert("sendJsonToServer successful, sended " + JSON.stringify(json1) + "got back: " + data);
            setMeaningofExpression(expression, data);
            $('#expressionTranslations').html(expressionsAsString());
        },
        error: function (xhr, status, error) {
            alert('sendJsonToServer error, tried to send ' + JSON.stringify(jsonToSend) + 'problem: ' + status + " " + error);
        }
    });

Controller:

    [HttpPost]
    public JsonResult Parse(String ValueToParse)
    {

            return Json(Parser.Parse(ValueToParse).ToArray());

    }

An example Json that fails:

解决方案

The problem was that ASP.NET blocked the Json because it considered it a security risk because of the <b></b> tags.
