Question

使用路由器时，我无法导航到带有ID参数的路由。

在我的组件中使用此代码

import { Router } from '@angular/router';
...
constructor(private router: Router) { }
...
public create() {
    ...
    this.router.navigate(['/category/edit', id]);
}

导致错误

Error: Cannot match any routes. URL Segment: 'category/edit;id=11'

如果在模板中使用它，它可以正常工作

<tbody>
    <tr *ngFor="let category of model">
        <td>{{category.name}}</td>
        <td>{{category.code}}</td>
        <td>
            <button type="button" class="btn btn-outline-primary" [routerLink]="['/category/edit', category.id]">Edit</button>
        </td>
    </tr>
</tbody>

这是我的路线定义

{
    path: 'category/edit/:id',
    component: EditComponent,
    resolve: {
        model: CategoryResolver
    }
}

尝试使用和不使用解析器，但无论如何都无法正常工作。

我正在使用 Angular 5.2.0 和 CLI 1.6.5

this.router.navigate(['/category/edit', id]);的结果是category/edit;id=11。当您传入对象而不是字符串时，将使用查询参数（如;id=11）。我想你的变量id是object类型而不是string。

id: Object = {id: '11'};

应改为

id: string = '11';

无法导航到Angular中具有ID的路由
