在 Docusing 中，我成功獲得了帶有演示帳戶的訪問令牌并創建了信封，當我移至生產帳戶時，我無法獲得訪問令牌并出現錯誤，因為“遠程服務器回傳錯誤：（400）錯誤請求。” 我成功地進行了 20 次 API 呼叫，并通過開發人員帳戶進行了審核并使其上線，API 密鑰詳細資訊也反映在生產登錄中。
舊代碼 這是我用來獲取訪問令牌的代碼。

我從 SQL 表中讀取并存盤在 DataTable 中的所有詳細資訊，從 DataTable 我傳遞該代碼中的所有詳細資訊。我在上面提到的生產環境中是否需要更改任何其他 URL？

現在我收到錯誤為“意外的 PEM 型別”，在生產帳戶中我使用 IK、UserID 并生成了新的 RSA 密鑰。
uj5u.com熱心網友回復：
首先，新應用程式不允許使用舊版身份驗證。您正在使用帶有明文密碼的 X-DocuSign-Authentication 標頭，這是一種傳統的身份驗證機制。它不安全，無法使用。
使用JWT 身份驗證并從開發環境更改為生產環境時，您必須執行以下操作：
- 通過上線并獲得批準以將您的 IK（應用程式）投入生產。
- 將您的 IK 提升到您的生產帳戶。
- 為生產帳戶中的新 IK 創建新的 RSA 密鑰。您不能使用開發者帳戶中的 RSA 密鑰。
- 身份驗證的 URL 從https://account-s.docusign.com更改為https://account.docusign.com
- 用戶的 userId 將是不同的 GUID - 需要更新
- 帳戶的 accountId 將是不同的 GUID - 需要更新
