Angular4 wait for callback to API without timeout

If you can help me, please.

I need to make a call in the API but there are a lot of data and I want Angular to wait for this term, at that moment I put a promise but it does not wait and as long as the API is handling the data on the NodeJS side the Angular makes a second call in the API by running over and creating two calls at the command line. My service code:

buscarConsumo(dadosConsumo): Promise<any> {
return this.http.post('${API_AZURE}/buscarconsumoperiodo', dadosConsumo)
  .toPromise()
  .then((data) => data)
  .catch((e) => console.log('Erro na Service', e));
}

My API takes 3 to 4 minutes to finish, I'll handle this in a future bank, but at the moment I need to bring the data to the client side, I tried to put timeout more unsuccessfully.

api javascript promises angular

With Eduardo's advice it worked, putting then on the component it waits for the end of the request on the server until the end:

buscarConsumoTotalResourceGroup(f) {

this.loading = true;
this.consumoService.buscarConsumoTotalResourceGroup(this.consumo)
.toPromise()
.then((consumoResourceG: any) => {
  this.consumoResourceG = consumoResourceG;
  this.loading = false;
  console.log('Retorno de Consumo Total por ResourceGroup: ', consumoResourceG);
});

}
