AngularJS 2 错误未定义索引 1

Question

我正在尝试实现一个 MeanStack 项目，当我尝试点击更新按钮时出现此错误：错误：请求的路径在索引 1

处包含未定义的段

有更新服务

 updateLocation(id, data) {
    return new Promise((resolve, reject) => {
        this.http.put('https://exemple.herokuapp.com/api/A/'+id, data)
          .map(res => res.json())
          .subscribe(res => {
            resolve(res);
          }, (err) => {
            reject(err);
          });
    });
  }

html

<form (submit)="onEditSubmit()">

和 component.ts

  onEditSubmit() {
    this.locationService.updateLocation(this.id,this.location).then((result) => {
      let id = result['_id'];
      this.router.navigate(['locations/', id]);
    }, (err) => {
      console.log(err);
    });
  }

Answer 1

将this.router.navigate(['locations/', id]);替换为this.router.navigate(['/locations', id]);
