Как исправить & ldquo; net :: ERR_CONNECTION_REFUSED и Ошибка: ошибка сети & rdquo; ошибка в рабочем проекте Reactjs, Django, Django Rest Frame

Я скопирую ваш код и сделал все, что мог, с этим кодом, он, вероятно, сработает, но если вы не с этим примером, вы поймете, как написать свой код для работы, как вы ожидаете.

getInfoDashBoard = () => {

let monthWiseAmountPayment = [];
let monthWiseAmountPaymentMonth = [];
let invPaid = 0;
let invUnpaid = 0;
let invOverdue = 0;
axios.get("http://localhost:5000/dashboard").then(response => {
let Mrr = response.data.payment.total_count * response.data.payment.total_payment_amount) / 1000;   

response.data.payment.month_wise.map(element => {
  let month = moment(element.month, "YYYY/MM").month();
  let formattedMonth = moment()
    .month(month)
    .format("MMMM")
    .toUpperCase();
  monthWiseAmountPayment.push(element.amount);
  monthWiseAmountPaymentMonth.push(formattedMonth);   
});

 this.setState({...this.state, monthlyRecurringRevenue: Mrr, 
    etRevenue: response.data.payment.total_payment_amount
    ,playerActive: response.data.organization.enrollments[1]
    ,playerEnded: response.data.organization.enrollments[3]
    ,playerInActive: response.data.organization.enrollments[5]
    ,monthWiseAmountPayment: monthWiseAmountPayment
    ,monthWiseAmountPaymentMonth: monthWiseAmountPaymentMonth
    ,monthWiseAmountPaymentMonthCopy: monthWiseAmountPaymentMonth
     });
});
}

componentDidMount() {
  this.getInfoDashBoard();
}

   handleMonth = (event) => {
   let month = event.target.value;     
   let monthWiseAmountPaymentMonth_ = [];
   let month = moment(month, "YYYY/MM").month();
   let formattedMonth = moment()
    .month(month)
    .format("MMMM")
    .toUpperCase();    

  monthWiseAmountPaymentMonth_ = monthWiseAmountPaymentMonthCopy.filter((item) => {
                                     if(item === formattedMonth) 
                                      {
                                          return item;
                                      }
                                    }
                                 );

     this.setState({selectedMonth: month, 
monthWiseAmountPaymentMonth: monthWiseAmountPaymentMonth_})
}
