是否有一个Javascript库来解析和打印作为JSON返回的.NET异常?

web-services asp.net javascript

如果调用ASMX web服务时发生异常,web服务将返回如下内容:

{"Message":"Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).","StackTrace":"   at System.Guid.TryParseGuidWithNoStyle(String guidString, GuidResult& result)\r\n   at System.Guid.TryParseGuid(String g, GuidStyles flags, GuidResult& result)\r\n   at System.Guid..ctor(String g)\r\n   at System.ComponentModel.GuidConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.FormatException"}

我想在alert或jQuery对话框中显示此消息,但为了做到这一点,我想将其打印出来。有没有一个JS库是为这个目的而构建的?

您不需要任何库,只需要jqueryui对话框。而且它真的很漂亮(有空间和入口)

function show_error(json) {
   $('.error').remove();
   $(document.documentElement).append('<div class="error"><h1><b>' + json['ExceptionType'] + 
      '</b>: ' + json['Message'] + '</h1><pre class="trace">' + json['StackTrace'] + 
      '</pre></div>');
   $('.error').dialog();
}

它会将堆栈跟踪放在pre-tag中。
