Angular asp.net中Okta的SSO。获取此错误时（IDX10501:签名验证失败。无法匹配密钥）

嗨，我已经实现了angular端代码，如

---

--类登录组件--

--类登录服务--

---

在服务器代码中，我把这个代码- ，但在代码中--

OpenIdConnectAuthProviderApi>>ValidateToken>>var principal=new JwtSecurityTokenHandler（）.ValidateToken（令牌、validationParameters、out var rawValidateToken）； 我犯了这个错误--

async OktaLogin(){
    let res =await this.oktaAuth.token.getWithPopup(this.tokenParams);
    this.loginService.oktaLoginStatusChangeCallback(res);
    }
    

 public oktaLoginStatusChangeCallback(resp){
        const model = new ExternalAuthenticateModel();
        model.authProvider = ExternalLoginProvider.OPENID;
        model.providerAccessCode = resp.tokens.accessToken.value;
        model.providerKey = resp.code;
        model.singleSignIn = UrlHelper.getSingleSignIn();
        model.returnUrl = UrlHelper.getReturnUrl();
 
        this._tokenAuthService.externalAuthenticate(model)
                .subscribe((result: ExternalAuthenticateResultModel) => {
                    if (result.waitingForActivation) {
                        this._messageService.info('You have successfully registered. Waiting for activation!');
                        return;
                    }
 
                    this.login(result.accessToken,
                        result.encryptedAccessToken,
                        result.expireInSeconds,
                        result.refreshToken,
                        result.refreshTokenExpireInSeconds,
                        false,
                        '',
                        result.returnUrl);
                });
 
    }
