我可以使用來自 agora.io 的臨時(shí)令牌進(jìn)行基本視頻通話，但是當(dāng)我從我的服務(wù)器創(chuàng)建令牌時(shí)，出現(xiàn)此錯(cuò)誤。我正在使用 NgxAgora 數(shù)據(jù)包。我嘗試設(shè)置區(qū)號，但在 NgxAgora 中沒有此選項(xiàng)。這是我的角度代碼： this.api.getmethod("appointment/gettoken/" + atob(this.acRouter.snapshot.params.id)).subscribe((data) => {    this.token = data['token']    this.client = this.ngxAgoraService.createClient({ mode: 'rtc', codec: 'h264' });           this.assignClientHandlers();      this.localStream = this.ngxAgoraService.createStream({ streamID: this.uid, audio: true, video: true, screen: false });    this.assignLocalStreamHandlers();    // Join and publish methods added in this step    this.initLocalStream(() => this.join(uid => this.publish(), error => console.error(error)));  })我使用 C# 在 web api 端使用這個(gè)函數(shù)： public string createagoratoken(string appointmentUid,DateTime appointmentDate,int appointmentId)    {        var tokenbuilder = new AgoraEntegration.Media.AccessToken(AgoraEntegration.AgoraEnums.AppEnums.appId, AgoraEntegration.AgoraEnums.AppEnums.appCertificate, appointmentUid, appointmentId.ToString());        appointmentDate = appointmentDate.AddMinutes(20);                            Int32 unixTimestamp = (Int32)(appointmentDate.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;        tokenbuilder.addPrivilege(AgoraEntegration.Media.Privileges.kJoinChannel, (uint)unixTimestamp);        tokenbuilder.addPrivilege(AgoraEntegration.Media.Privileges.kInvitePublishAudioStream, (uint)unixTimestamp);        tokenbuilder.addPrivilege(AgoraEntegration.Media.Privileges.kInvitePublishVideoStream,(uint)unixTimestamp);        string token = tokenbuilder.build();        return token;    }我還使用這個(gè)庫作為 C# 的訪問令牌 Github 訪問令牌
