Вопрос

У меня есть веб-сервис .NET, возвращая следующие 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"}]}]}

Мой клиентский код выглядит следующим образом:

$('#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 + ' ');
        }

    });

Если я вставил возвращенную JSON в http://www.jsonlint.com/ Затем он подтверждает, но jQuery ajax вызывает ошибки с TextStatus = «ParserError» и erlorthrown = "Invalid json". Мой Web SVC определяется следующим образом:

[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)
    {

Кто-нибудь знает, что происходит? Спасибо.

Так предположительно это проблема. Что-то не так с моими объявлениями веб-метода выше?

Сервер сейчас делает это: {«сообщение»: «Неверный примитив JSON: getqcardjson»., «Stacktrace»: «В System.Web.script.Serialization.javascriptbejectedeserializer.deserializePrimiteObjectedObject () r n на системе. .JavasprctobjectDeserializer.deserializeInternal (int32 глубина) r n на system.web.script.serialization.javascriptobjectDeserializer.basicdeserialize (строковый ввод, int32 multlimlimit, javascripterializer serializer) r n на system.web.scrize.serialization.javascripterializ (JavaScripterializer Serializer, вход строки, тип типа, INT32 Mediclimit) R N на System.Web.script.Services.resthandler.getRawparamsfromgetlerquest (контекст httpContext, javascripterializer serializer, webservicddata modeldata) r n на system.web.script.

Это было полезно?

Решение

Как правило, вы должны установить contentType При создании запроса JSON к веб-сервису ASP.NET, как это:

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

В противном случае, что ответ JSON завернут в XML, когда он возвращается.
