如何在Angular 7应用中传递Django变量

# views.py
from rest_framework.views import APIView
from rest_framework.response import Response

class DjangoVariableView(APIView):
    def get(self, request):
        variable = "Hello from Django"
        return Response(variable)

// django.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class DjangoService {
  private apiUrl = 'http://your-django-api-url';

  constructor(private http: HttpClient) { }

  getDjangoVariable(): Observable<string> {
    return this.http.get<string>(`${this.apiUrl}/django-variable/`);
  }
}

// component.ts
import { Component, OnInit } from '@angular/core';
import { DjangoService } from './django.service';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  djangoVariable: string;

  constructor(private djangoService: DjangoService) { }

  ngOnInit() {
    this.djangoService.getDjangoVariable().subscribe(variable => {
      this.djangoVariable = variable;
    });
  }
}

<!-- component.html -->
<p>{{ djangoVariable }}</p>
