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？

Question

因此，我将JSON字符串发送到服务器以通过jQuery ajax进行解析。 我从Glosbe字典的API获取JSON。 在大多数情况下，它可以按预期运行，但是某些JSON会失败。 有趣的是，在这些情况下，我会收到“内部服务器错误”，但是当我尝试调试应用程序时，似乎甚至没有调用控制器。 我不知道那怎么可能。

这是我的观点：

        $.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());

    }

失败的示例Json：

Answer 1

我也为类似的事情而苦恼。 尝试这个：

var ValueToSend = {'': jsonToSend };

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

注意，我删除了contentType和dataType ，并且json字符串包含在具有空属性名称的对象中。 本文对您有所帮助： http : //encosia.com/using-jquery-to-post-frombody-parameters-to-web-api/还请确保您的路由在服务器上正确运行； 我建议您对URL进行硬编码，直到您确定一切正常为止，因此我将url: '@Url.Action("Parse", "GetMeaning")'替换为实际路由。

问题是ASP.NET阻止了Json，因为它由于<b></b>标记而将其视为安全隐患。
