如何正确地从angular向python发送http请求

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    HttpClientModule
  ]
})
export class AppModule { }

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) { }

this.http.get('http://your-python-api-url').subscribe((response) => {
  console.log(response);
}, (error) => {
  console.error(error);
});

const requestBody = { key: 'value' };

this.http.post('http://your-python-api-url', requestBody).subscribe((response) => {
  console.log(response);
}, (error) => {
  console.error(error);
});
