Angular2 路由 - 使用 LocationStrategy 添加主题标签不起作用? [英] Angular2 routing - adding the hashtag using LocationStrategy not working?
问题描述
我正在关注 Angular2 文档中的简单快速入门应用程序，并且我正在使用 spring 后端来运行它.我的问题是角度路由器从 URL 中删除了主题标签，所以应该是 example.com/#/dashboard 现在是 example.com/dashboard.
I'm following the simple quickstart app from the Angular2 docs and I'm using a spring backend to run it. My problem is that the angular router ditched the hashtag from the URL so what should have been example.com/#/dashboard is now example.com/dashboard.
我正在使用 StackOverflow 上的一堆帖子中指定的 LocationStrategy 方法.下面是我的简单例子:
I am using the LocationStrategy method specified in a bunch of posts on StackOverflow. Below is my simple example:
文件:main.ts
///<reference path="../node_modules/angular2/typings/browser.d.ts"/>
import {bootstrap} from 'angular2/platform/browser'
import {provide} from 'angular2/core';
import {LocationStrategy, HashLocationStrategy} from 'angular2/router';
import {TestComponent} from './simple/test.component'
bootstrap(
TestComponent,
[
provide(LocationStrategy, { useClass: HashLocationStrategy })
]
);
文件:test.component.ts
import {Component} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS } from 'angular2/router';
@Component({
selector: 'test1',
template: "<h1>This is test1 component</h1>"
})
export class Test1 { };
@Component({
selector: 'test2',
template: "<h1>This is test2 component</h1>"
})
export class Test2 { };
@Component({
selector: 'my-app',
template: `
<h1>This is my test app</h1>
<nav>
<a [routerLink]="['Test1']">Test1</a>
<a [routerLink]="['Test2']">Test2</a>
</nav>
<router-outlet></router-outlet>
`,
directives: [ROUTER_DIRECTIVES],
providers: [ROUTER_PROVIDERS]
})
@RouteConfig([
{
path: '/test1',
name: 'Test1',
component: Test1
},
{
path: '/test2',
name: 'Test2',
component: Test2
}
])
export class TestComponent { }
文件:index.html
<html>
<head>
<base href="/">
<title>This is an Angular 2 test</title>

}
});
System.import('app/main').then(null, console.error.bind(console));
</script>

<body>

</html>
我正在使用 Angular2 2.0.0-beta.9，这是我看到的行为.请注意，@RouteConfig 中的 2 个路径都没有标记为 useAsDefault: true.
I'm using Angular2 2.0.0-beta.9 and this is the behavior that I see. Note that none of the 2 paths in the @RouteConfig are marked with useAsDefault: true.
当我尝试打开 http://localhost:8080/#/test1 页面打开正常，但是当我单击 TestComponent 模板中的 2 个锚点之一时，主题标签获取掉线了.
When I try to open up http://localhost:8080/#/test1 the page opens fine, but when I click on one of the 2 anchors in the TestComponent template, the hashtag gets dropped.
然后，如果我将 path1 设置为 useAsDefault: true，即使我尝试访问 http://localhost:8080/，主题标签也会立即删除#/test1.
Then if I set path1 to be useAsDefault: true, the hashtag gets dropped immediately even when I try to visit http://localhost:8080/#/test1.
有人可以告诉我是我做错了什么还是错误?我只想在 URL 中取回主题标签.
Can someone please tell me if I'm doing something wrong or if that's a bug? I just want to get the hashtag back in the URL.
推荐答案
Angular2 <= RC.5
ROUTER_PROVIDERS 需要在 LocationStrategy 之前添加，否则您之前添加的 LocationStrategy 会被覆盖.
The ROUTER_PROVIDERS need to be added before LocationStrategy otherwise your previously added LocationStrategy gets overridden.
bootstrap(
TestComponent,
[
ROUTER_PROVIDERS,
// must be listed after `ROUTER_PROVIDERS`
provide(LocationStrategy, { useClass: HashLocationStrategy })
]
);
删除这一行
providers: [ROUTER_PROVIDERS]
来自 TestComponent
