How to fix TypeError: Cannot read property 'post' of undefined on Axios with Nestjs cronjob

Question

我尝试使用 cron 调度程序每 15 秒获取一次身份验证令牌（测试目的）cron 应该调用 auth 端点但我得到 Exception has occurred: TypeError: Cannot read property 'post' of undefined

 @Cron(CronExpression.EVERY_15_SECONDS)
    async handleCron() {
        //const Primetimeauth = this.PrimetimeAuth()

        const primeAuth = await this.httpService.post('https://clients.com/api/auth', {
            "username": process.env.username,
            "password": process.env.password
        }).toPromise();

        if (primeAuth.status != 200) {
            throw new HttpException({
                message: `Vending Authentication Failed`,
                statusCode: primeAuth.status
            }, HttpStatus.BAD_REQUEST);
        }

        const data = primeAuth.data;

        await this.PrimetimeAuthToken.updateOne({ "_id": "3dtgf1341662c133f0db71412drt" }, {
            "$set":
            {
                token: data.token,
                tokenExpirationTime: data.expires,
                timeTokenReceived: new Date
            }
        });

        return data;
    }

Cron 表达式不适用于请求范围的提供程序，因为可能运行在请求的上下文之外。因此，所有依赖项都以 undefined 的形式出现。要解决此问题，您需要一个非请求范围的提供程序。
