私はJSONを初めて使用しており、データソースから返されたJSON形式の文字列を読み込もうとしています。私は古典的なASPを使用して、私はVbsJsonのクラスコードから次のエラーを取得しています。VbsJsonが解析エラーのためオブジェクトを返す
マイクロソフトのVBScript実行時エラー '800A01A8'
オブジェクトは、エラーが発生しているところ、私はコメント
/MyTestPage.asp、行のコードで以下83
を必要としていました。私の望みは、コードが解析し、並べ替えるためのデータのキー/値のペアを提供することです。ここで
は、ここでJSON文字列

がVbsJsonを呼び出す私のコードです：
Dim simonResponseArray
Dim jsonClsUser, jsonParsedUser
Dim fso, json
Set json = New VbsJson
Set fso = server.CreateObject("Scripting.Filesystemobject")
simonXmlResponse = fso.OpenTextFile("C:\Temp\users_small.json").ReadAll
Set jsonClsUser = New VbsJson
Set jsonParsedUser = jsonClsUser.Decode(simonXmlResponse) 'This is where the error occurs
また、以下VbsJsonのクラスコードです：

がある場合誰かに必要な情報があれば、私に知らせてください。古典的なASPのJSONを消費することは、私にとっては難しいことです。
MyTestPage.aspの行は行83ですか？ –
これはなぜオフトピックですか？ OPは十分な情報を提供しました – SearchAndResQ
私は喜んでこの質問をon-topicに編集しますので、誰かが私がこの質問を終了させた理由を教えてください。 – EddieAzul
