选用get读取本地json
1.安装@angular/http
npm install @angular/http@latest
2.app.module.ts中引入
import { HttpModule, JsonpModule } from '@angular/http';
imports: [
HttpModule,
JsonpModule,
],
3.使用的ts文件中
引入
import { Http, Jsonp } from "@angular/http";
constructor(private http: Http, private jsonp: Jsonp){
}
getJson(){
let url = "/assets/json/setting.json";
this.http.get(url).subscribe(
function (res) {
let data = res.json();
console.log(data);
}, function (err) {
var errdata = err.json();
console.log("信息：" + errdata.message);
});
}
