.NET Webサービスが次のJSONを返しています。

{"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"}]}]}

私のクライアントコードは次のとおりです。

$('#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 + ' ');
        }

    });

返されたjsonを貼り付けた場合 http://www.jsonlint.com/ 次に、検証しますが、jquery ajaxはtextStatus = "parsererror"およびerrorthrown = "invalid json"を使用してエラーを呼び出します。私のWeb SVCは次のように定義されています。

[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)
    {

誰もが何が起こっているのか知っていますか？ありがとう。

Firefoxコンソールの応答は次のように表示されます。

おそらくそれが問題です。上記の私のWebメソッド宣言に何か問題がありますか？

{"Message"： "invalid json Primitive：getqcardjson。"、 "stacktrace"： "at System.web.script.serialization.javascriptobjectdeserializer.deserializeprimitiviteObject（） r n at System.Web.scripiation。 .javascriptobjectdeserializer.deserializeinternal（int32深さ） r n at System.web.script.serialization.javascriptobjectdeserialize.basicdeserialize（string input、int32 depthlimit、javascriptserializer serializer） （javascriptserializer serializer、string input、type type、int32 depthlimit） r n at system.web.script.services.resthandler.getrawparamsfromgetRequest（httpcontextコンテキスト、javascriptserializer serializer、webservicemethoddata methatdata aT services.resthandler.getrawparams（webservicemethoddata methoddata、httpcontext context） r n at System.web.script.services.services.executewebservicecall（httpcontextコンテキスト、webservicemethoddata methatdata） " .argumentexception "}

役に立ちましたか？

解決

通常、設定する必要があります contentType このようなASP.NET WebサービスにJSONリクエストを行うとき：

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

それ以外の場合、JSON応答が戻ってきたときにXMLに包まれています。
