如何订阅 angular js2 中的后端数据

how to subscribe to back end data in angular js2

导出 class 搜索 {

data: string;
prop: string = 'connenct';
details: ISearch[];
constructor(public http: Http,public _profileservice: GetSocietyList) {
    this.http = http;
      this._profileservice.getSocietyList()
              .subscribe(
               response => {
                    this.details = response;

            })
        })

}

我在这里订阅了对细节的全部回复,但我只想要我的细节的一部分,即 connection_status = 3 和 4.Can 有人请提供帮助。

只筛选你需要的

response => {
  this.details = response.filter(
    r => r.connection_status === 3 || r.connnection_status === 4);
