C# 将带有POST的JSON发送到服务器进行解析-为什么此ajax调用失败？

因此，我向服务器发送一个JSON字符串，以便通过jQueryAjax进行解析。我从Glosbe字典的API中获取JSON。大多数情况下，它都能按预期工作，但某些JSON会失败。有趣的是，在这些情况下，我得到了一个“内部服务器错误”，但当我试图调试应用程序时，似乎控制器甚至没有被调用。我不知道这怎么可能

以下是我的看法：

        $.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);
        }
    });

控制器：

    [HttpPost]
    public JsonResult Parse(String ValueToParse)
    {

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

    }

失败的Json示例：

我也遇到过类似的问题。试试这个：

var ValueToSend = {'': jsonToSend };

$.ajax({
    url: '@Url.Action("Parse", "GetMeaning")',
    data: ValueToSend 
    type: 'POST',
    success:....

---

请注意，我删除了

contentType

和

dataType

，并且json字符串包含在一个属性名为空的对象中。本文提供了帮助：还可以确保在服务器上正确运行路由；我建议将URL保留为硬编码，直到您确定所有内容都正常工作为止，因此我将替换它

url:'@url.Action（“Parse”，“GetMeaning”）

与实际路由。

问题在于ASP.NET被阻止
