jquery - 通过 AJAX 将引号传递到 Web 服务时出错

Question

我使用 .ajax 传递数据，以下是我的数据和 contentType 属性:

data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}',
contentType: 'application/json; charset=utf-8',

服务器端我的代码如下所示:

<WebMethod()> _
Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String

用户输入很明显，但Options结构如下:

Public Structure Options
    Dim Foo1 As Boolean
    Dim Foo2 As Boolean
    Dim Flags As String
    Dim Immunity As Integer
End Structure

当 $('#txtInput') 不包含双引号时，一切正常，但如果存在双引号，我会收到错误(对于 asd"的输入):

{"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected. (22): { \"UserInput\" : \"asd\"\",\"Options\" : { \"Foo1\":false, \"Foo2\":false, \"Flags\":\"\", \"Immunity\":0}}","StackTrace":"   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n   at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

知道如何避免此错误吗？另外，当我直接传递带有引号的相同输入时，它工作得很好。

您是否尝试过转义文本，或者将双引号替换为单引号，或者将双引号替换为转义字符:\"
