JSON valido in base a jQuery ma non JSONlint

Question

Ho un servizio Web .NET restituire il seguente JSON:

{"command":"getqcardjson","valuesets":[{"datatable":"eaa65990-8f88-45e0-966b-610858ad4cb6","values":[{"Id":"eaa65990-8f88-45e0-966b-610858ad4cb6","InternalName":"Alpha Profile","TableName":"Alpha Profile","OnMainMenu":"","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"100","IsChained":"","IncludeInGlobalSearch":"False","IsModelObject":"","IsSchemaObject":"","IsSecured":"False","IsFileNewMenu":"False","IsUpdateShouldRippleCache":"False","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"Information.png","DefaultObjectLayoutStyle":"980163c2-2688-465d-9383-e5ad4dbf631f","Notes":"This is a test Enquiry profile object called Alpha Profile","Caption":"Alpha Profile","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"","IsGeocodable":""},{"Id":"2cbc4bc4-7db0-4344-b49a-bbc8ed4e9e60","InternalName":"CompMP","TableName":"CompMP","OnMainMenu":"True","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"100","IsChained":"","IncludeInGlobalSearch":"False","IsModelObject":"False","IsSchemaObject":"False","IsSecured":"","IsFileNewMenu":"False","IsUpdateShouldRippleCache":"","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"profile.png","DefaultObjectLayoutStyle":"980163c2-2688-465d-9383-e5ad4dbf631f","Notes":"","Caption":"CompMP","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"","IsGeocodable":""},{"Id":"f33038ce-2a64-4e79-99fc-ad6aaf90c2bb","InternalName":"ContactProfile","TableName":"ContactProfile","OnMainMenu":"True","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"100","IsChained":"","IncludeInGlobalSearch":"False","IsModelObject":"False","IsSchemaObject":"False","IsSecured":"","IsFileNewMenu":"False","IsUpdateShouldRippleCache":"","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"profile.png","DefaultObjectLayoutStyle":"980163c2-2688-465d-9383-e5ad4dbf631f","Notes":"","Caption":"ContactProfile","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"","IsGeocodable":""},{"Id":"fbb39ed3-0409-4712-b6dd-f6853b079aa6","InternalName":"QCardInqMP","TableName":"QCardInqMP","OnMainMenu":"True","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"100","IsChained":"","IncludeInGlobalSearch":"False","IsModelObject":"False","IsSchemaObject":"False","IsSecured":"","IsFileNewMenu":"False","IsUpdateShouldRippleCache":"","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"profile.gif","DefaultObjectLayoutStyle":"980163c2-2688-465d-9383-e5ad4dbf631f","Notes":"","Caption":"QCardInqMP","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"","IsGeocodable":""},{"Id":"41db39fb-fda8-4c5c-adc4-6e6c1ba77b90","InternalName":"QCEventAttendance","TableName":"QCEventAttendance","OnMainMenu":"True","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"","IsChained":"","IncludeInGlobalSearch":"","IsModelObject":"","IsSchemaObject":"","IsSecured":"","IsFileNewMenu":"","IsUpdateShouldRippleCache":"","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"","DefaultObjectLayoutStyle":"","Notes":"","Caption":"Attendance details","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"","IsGeocodable":""},{"Id":"8f186be5-d0ec-4dc7-bfd5-9b9190644c1f","InternalName":"QCFilms","TableName":"QCFilms","OnMainMenu":"True","DefaultDataSourceId":"bb4d1622-2e48-40b6-bea7-6355d701445c","DefaultOrder":"","IsChained":"","IncludeInGlobalSearch":"False","IsModelObject":"","IsSchemaObject":"","IsSecured":"False","IsFileNewMenu":"False","IsUpdateShouldRippleCache":"False","AdvancedSearchQueryId":"","CompoundViewQueryId":"","GlobalSearchQueryId":"","Icon":"","DefaultObjectLayoutStyle":"2b69073c-4035-4597-acc0-4d8345ba9d1c","Notes":"","Caption":"QCFilms","IsProfileObject":"True","ShortCacheQueryId":"","WorkflowForCreation":"","IsAllowNewFromExisting":"False","IsGeocodable":"False"}]}]}

Il mio codice cliente è la seguente:

$('#panelMiddle').append('Getting Json');
    var url = "svc.asmx/GetJSONData?command=getqcardjson&qcardid=" + QCardId;
    $.ajax({
        url: url,
        dataType: 'json',
        success: function(data) {
            $('#panelMiddle').append('Success');
        },
        complete: function() {
            $('#panelMiddle').append('Completed');
        },
        error: function(XMLHttpRequest, textStatus, errorThrown) {
        $('#panelMiddle').append(' #ERROR:' + textStatus + '# ' + errorThrown + ' ');
        }

    });

Se incollo il JSON restituita in http://www.jsonlint.com/ allora convalida, ma gli errori di chiamata jQuery AJAX con textStatus = "ParserError" e errorThrown = "Invalid JSON". Il mio web SVC è definito come segue:

[WebMethod(EnableSession = true)] // Required to create web service, even when json decoration present
    [ScriptMethod(UseHttpGet = true,ResponseFormat = ResponseFormat.Json)] // Required decoration to ensure we can call using json
    public string GetJSONData(string command)
    { 

Qualcuno sa che cosa sta succedendo? Grazie.

Firefox spettacoli di risposta di console come segue:

quindi, presumibilmente, che è il problema. Qualcosa non va con le mie dichiarazioni di metodo web di cui sopra?

Server ora di fare questo: { "Messaggio": "non valido JSON primitivo:. Getqcardjson", "StackTrace":" a System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject () \ r \ n al System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal ( profondità Int32) \ r \ n al System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize (ingresso String, Int32 depthLimit, JavaScriptSerializer serializzatore) \ r \ n al System.Web.Script.Serialization.JavaScriptSerializer.Deserialize (JavaScriptSerializer serializzatore, String ingresso, tipo Type, Int32 depthLimit) \ r \ n al System.Web.Script.Services.RestHandler.GetRawParamsFromGetRequest (HttpContext contesto, JavaScriptSerializer serializzatore, WebServiceMethodData methodData) \ r \ n a System.Web.Script.Services.RestHandler.GetRawParams (WebServiceMethodData methodData, HttpContext contesto) \ r \ n al System.Web.Script.Services.RestHandler.ExecuteWebServiceCall (HttpContext contesto, WebServiceMethodData methodData) " "ExceptionType":" System.Argument Eccezione "}

Answer 1

In genere è necessario impostare la contentType quando si effettua una richiesta di JSON a un servizio web ASP.Net, in questo modo:

$.ajax({
  contentType: 'application/json; charset=utf-8',
  dataType: 'json',
  //rest of your current options..
});

In caso contrario, che la risposta JSON è avvolto in XML quando ritorna.
