我有一个.NET网络服务返回以下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"}]}]}

我的客户端代码，如下所示：

$('#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 + ' ');
        }

    });

如果我返回的JSON粘贴到 http://www.jsonlint.com/ 然后它验证，但textStatus = “parsererror” 和errorThrown = “无效的JSON” jQuery的AJAX调用错误。我的网页SVC定义如下：

[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)
    {

谁知道怎么回事？感谢。

火狐控制台响应显示如下：

所以推测这就是问题所在。有毛病我的Web方法声明上面？

服务器现在正在做这样的： { “消息”： “无效JSON原始：getqcardjson”， “堆栈跟踪”：”在System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject（个）\ r \ n在System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal（深度Int个）\ r \ n在System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize（字符串输入，INT32 depthLimit，JavaScriptSerializer串行个）\ r \ n在System.Web.Script.Serialization.JavaScriptSerializer.Deserialize（JavaScriptSerializer串行器，字符串输入，类型类型，的Int32 depthLimit）\在System.Web.Script.Services.RestHandler.GetRawParamsFromGetRequest r \ N（HttpContext的上下文中，JavaScriptSerializer串行器，WebServiceMethodData methodData个）\ r \ n在System.Web.Script.Services.RestHandler.GetRawParams （WebServiceMethodData methodData，HttpContext的上下文）\ r \ n在System.Web.Script.Services.RestHandler.ExecuteWebServiceCall（HttpContext的上下文中，WebServiceMethodData methodData） “ ”ExceptionType“：” System.Argument异常“}

有帮助吗？

解决方案

通常你具有使JSON请求到一个ASP.Net Web服务时，这样来设置contentType：

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

否则该JSON响应被包裹在XML当它回来。
