鉻標記簽署擴展

我正在嘗試做一個擴展，將與本機通訊主機chrome-token-signing溝通。我使用金雅拓智能卡讀卡器。我安裝了擴展，當我退出或放入任何字符串時，它會返回一個cmd窗口。我有消息日誌TEST: ERROR {"message":"Error when communicating with the native messaging host."} 我需要做一些事情我已經安裝在註冊表中的主機像HKEY_LOCAL_MACHINE\software\Google\Chrome\NativeMessagingHosts\ee.ria.esteid和價值C:\Users\dev\Desktop\chrome-token-signing\host-windows\ee.ria.esteid.json鉻標記簽署擴展
