For loop an HTTP request logical error

Ionic Framework ionic-v3

Hi @dmlkl :wave:

It’s a common async problem: all the calls made to this.requestService are asynchronous, but the loop keeps executing. In my experience, the cleanest way to make this async loop synchronous is by using async/await and waiting for the promises to resolve:

async function GetGeneralInfo() {
  for (let i = 0; i < deviceData.length; i++) {
    console.log('Loop Start')
    const telemetryData = await this.requestService.GetTelemetryData(loginAcc.token, deviceData[i].id.id);

    console.log('After GetTelemetryData()');
    const status = JSON.parse(telemetryData.status);

    if (status === 401) {
      console.log('Token Expired...');
      const refreshTokenResponse = await this.requestService.RefreshToken(loginAcc.token, loginAcc.refreshToken);

      //i need to terminated the for loop and recall this method with new token
      return this.GetGeneralInfo();
    } else if (status === 200) {
      console.log('Token is valid and data is given....');
      const data = JSON.parse(telemetryData.data);
    }
  }
}

Hope it helps,
Rodrigo
