HTTP Get请求(Wordpress网站Rest API调用)在iOS应用程序(Ionic4和angular)中不起作用

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

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule, HttpClientModule],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

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

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {

  constructor(private http: HttpClient) {}

  ngOnInit() {
    this.sendGetRequest();
  }

  sendGetRequest() {
    this.http.get('https://your-wordpress-api-endpoint')
      .subscribe((response) => {
        console.log(response);
        // 处理返回的数据
      }, (error) => {
        console.error(error);
      });
  }

}
