Angular 4.2.4：无法检索JSON

Question

I'm struggling to retrieve JSON from a Rest API. Here is my code

 getSports(): void { this.http.get(this.url, { headers: new HttpHeaders().set('Content-Type', 'application/json').set('Accept', 'application/json') }).subscribe(data => { console.log(data); }); } 

null is printed to console. What am I'm doing wrong?

Answer 1

响应返回状态为200。我遇到的问题是json格式错误
