我使用msal获取代币，如下所示：

const msal = require('@azure/msal-node');
const msalConfig = {
    auth: {
        clientId: config.MS_CLIENT_ID,
        authority: config.AAD_ENDPOINT + 'consumers', //config.TENANT_ID,
        clientSecret: config.MS_CLIENT_SECRET,
    }
};

const cca = new msal.ConfidentialClientApplication(msalConfig);

const authCodeUrlParameters = {
                        scopes: ["Mail.ReadWrite"],
                        redirectUri: config.MS_REDIRECT_URI,
                    };

   // get url to sign user in and consent to scopes needed for application
  cca.getAuthCodeUrl(authCodeUrlParameters);

  let tokenReq = {
                        code: ctx.params.Token,
                        scopes: ["Mail.ReadWrite"],
                        redirectUri: config.MS_REDIRECT_URI
                    }
                    const tokenRes = await cca.acquireTokenByCode(tokenReq);

我没有从acquiretokenbycode方法获取刷新令牌
