Nestjs using axios
You have to make sure to handle your responses as a JSON you can return it as a promise and get the data, use one of both or HttpService or axios
import { Get, Controller, HttpService } from '@nestjs/common';
@Controller()
export class AppController {
constructor(private readonly http: HttpService) {}
@Get()
root(): {
return this.http.get('https://api.github.com/users/quen2404')
.toPromise()
.then(res => res.data)
.catch(err => /*handle error*/)
}
}
as you write in your example, get
method return AxiosResponse<>
and contains circular reference.
So if you want to proxify webservice https://api.github.com/users/januwA
, you should return AxiosResponse.data
:
import { Get, Controller, HttpService } from '@nestjs/common';
import { AxiosResponse } from 'axios'
import { Observable } from 'rxjs'
@Controller()
export class AppController {
constructor(private readonly http: HttpService) {}
@Get()
root(): Observable<any>{
return this.httpClient.get('https://api.github.com/users/quen2404')
.pipe(map(response => response.data));
}
}
You cannot just return the whole AxiosResponse
object because it cannot be serialized to JSON. You most likely want to get the response data
like this:
@Get()
root() {
return this.http.get('https://api.github.com/users/januwA').pipe(
map(response => response.data)
);
}
or alternatively using Promises
:
@Get()
async root() {
const response = await this.http.get('https://api.github.com/users/januwA').toPromise();
return response.data;
}
