在angular2中如何将id值分配给url

Question

这里我写了angular2 url部分为

  onselect(StateId: Country) {
        var GetstateValue = this.http.post("http://localhost:34339/Home/GetStateById/",+StateId)
 GetstateValue.subscribe(res => this.Success)

但它不是Binding StateId值（这里的id值是来的）

Answer 1

Angular GET和POST

获取方法：

＆＃13;

 onselect(StateId: Country) {
        var GetstateValue = this.http.get("http://localhost:34339/Home/GetStateById/"+StateId)
 GetstateValue.subscribe(res =>{ this.Success=res; console.log(res);)

＆＃13;

＆＃13;

＆＃13;

发布方法

＆＃13;

＆＃13;

 onselect(StateId: Country) {
  const header = new Headers();
      header.append('Content-Type', 'application/x-www-form-urlencoded');
      let data = StateId;
        var GetstateValue = this.http.post("http://localhost:34339/Home/GetStateById/", data, {headers: header}).map(res=>res.json());
 GetstateValue.subscribe(res => this.Success);
