Ionic 3 CORS not working on device

Hi,

I have an api and I installed CORS plugin in chrome. my problem is my api is not working on ionic build or rather in device. but in my ionic serve and I enabled CORS plugin extension it’s working. Can you help me with my problem.

here’s my function

 getMatches(){
  
    this.http.get('https://api.wh.geniussports.com/v1/basketball/competitions/19816/matcheslive?ak=eebd8ae256142ac3fd24bd2003d28782&fromDate=2017-11-17&toDate=2017-12-17&teamId=88261&limit=1')
    .map(res => res.json())
    .subscribe(data => {
      this.dataMatches = data.response.data;
      console.log(this.dataMatches);
    }, err => {
      console.log(err);
    });
  }

here’s my device inspector result for ios

You need to allow Access-Control-Allow-Origin in your server side script

@avishai_peretz_dev is there’s any other option rather than access-control-allow-origin in server side?

What language your server script?
