7- http请求

angular 中自带的有http请求

//app.module.ts中去注册
+import {HttpClientModule} from '@angular/common/http'
@NgModule({
  ...
  imports: [
    BrowserModule,
    + HttpClientModule
  ]
  ...
})

//app.component.ts配置
+ import {HttpClient} from '@angular/common/http'
export class AppComponent {
 + movies:any = [];
 + constructor(public http:HttpClient){}
 + ngOnInit(){
 +    var url:string = "http://localhost:8000/top250";
 +       this.http.get(url).subscribe((res:any)=>{
 +      this.movies = res.result;  //设置data中的数据
     })
  }
}
