在Angular中使用来自observable的数据进行http post

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

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

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

constructor(private http: HttpClient) { }

postData(data: any): Observable<any> {
  const url = 'http://example.com/api/post'; // 替换为实际的API端点

  return this.http.post(url, data);
}

this.postData({ name: 'John', age: 25 }).subscribe(
  response => {
    console.log(response); // 处理响应数据
  },
  error => {
    console.error(error); // 处理错误
  }
);
