使用Angular 2 http操作将数字传递给MVC控制器

import { HttpModule } from '@angular/http';

@NgModule({
  imports: [
    // Other imports...
    HttpModule
  ],
  // Other configurations...
})
export class AppModule { }

import { Http } from '@angular/http';

@Component({
  // Component configurations...
})
export class YourComponent {
  constructor(private http: Http) { }
  
  // Other component methods...
}

import { Headers, RequestOptions } from '@angular/http';

// ...

sendNumberToController(number: number) {
  const url = '/api/your-controller';
  const headers = new Headers({ 'Content-Type': 'application/json' });
  const options = new RequestOptions({ headers: headers });
  const body = { number: number };

  this.http.post(url, body, options)
    .subscribe(
      response => {
        // Handle response from the controller...
      },
      error => {
        // Handle error...
      }
    );
}
