无效的JSON格式

我正在构建JSON对象，并使用JQuery ajax将其传递到服务器。

data: "{'authorID' : '" + authorID +
      "', 'title' : '" + encodeURIComponent(blogTitle) +
      "', 'msg' : '" + encodeURIComponent(blogBody) +
      "', 'preview' : '" + encodeURIComponent(mediaContent) +
      "', 'layoutID' : '" + previewLayoutId +
      "', 'threadID' : '" + threadID + "'}"

但是，当我的blogBody变量包含'代码时，将失败并显示错误消息：

{"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected. (107): {\u0027authorID\u0027 : \u0027148385\u0027, \u0027title\u0027 : \u0027123213\u0027, \u0027msg\u0027 : \u0027%3Cp%3Eqqq%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3E\u0027\u0027\u0027\u0027%3C%2Fp%3E\u0027, \u0027preview\u0027 : \u0027\u0027, \u0027layoutID\u0027 : \u00271\u0027, \u0027threadID\u0027 : \u00270\u0027}","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(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n   at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n   at System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext context, JavaScriptSerializer serializer)\r\n   at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

有人可以说错误在哪里以及如何解决？

回答：

在JSON中，键必须用双引号（"）而不是单引号（'）引起。同样，字符串值必须用双引号而不是单引号引起来。您正在使用单引号。例如，authorId标题文字前后。

因此，至少，您需要交换这些引号，例如：

data: '{"authorID" : "' + authorID +
      '", "title" : "' + encodeURIComponent(blogTitle) +
      '", "msg" : "' + encodeURIComponent(blogBody) +
      '", "preview" : "' + encodeURIComponent(mediaContent) +
      '", "layoutID" : "' + previewLayoutId +
      '", "threadID" : "' + threadID + '"}'
