[英]angular 2 import of component works in VS, but gives 404 in browser
I have a very simple app setup: 我有一个非常简单的应用设置:
Index.html: Index.html:
<!doctype html>
<html>
<head>
<title>Angular 2</title>
<!-- Libraries -->
<script src="/lib/js/es6-shim.js"></script>
<script src="/lib/js/angular2-polyfills.js"></script>
<script src="/lib/js/system.src.js"></script>
<script src="/lib/js/rxjs/bundles/Rx.js"></script>
<script src="/lib/js/angular2.dev.js"></script>
<!-- Stylesheet -->
<link rel="stylesheet" type="text/css" href="/app/reddit_v2/style/semantic/semantic.min.css">
<link rel="stylesheet" type="text/css" href="/app/reddit_v2/style/styles.css">
</head>
<body>
<!-- Configure System.js, our module loader -->
<script>
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('/lib/spa/app.js')
.then(null, console.error.bind(console));
</script>
<!-- Menu Bar -->
<div class="ui menu">
<div class="ui container">
<a href="#" class="header item">
header
</a>
<div class="header item borderless">
<h1 class="ui header">
Angular 2
</h1>
</div>
</div>
</div>
<div class="ui main text container">
<app></app>
</div>
</body>
</html>
app.ts Here I'm importing post.component and it seems to work well. app.ts在这里,我正在导入post.component,它似乎运行良好。
import { bootstrap } from 'angular2/platform/browser';
import { Component } from 'angular2/core';
import { Post } from './components/post.component';
@Component({
selector: 'app',
templateUrl: '/app/app.html',
directives: [Post]
})
class App {
constructor() {
}
ngOnInit() {
console.log('app');
}
addArticle(title: HTMLInputElement, link: HTMLInputElement): void {
console.log(`adding title: ${title.value} and link: ${link.value}`);
}
}
bootstrap(App);
post.component.ts post.component.ts
import { Component } from 'angular2/core';
@Component({
selector: 'post',
template: '<p>test</p>'
//templateUrl: '/app/component/post.component.html'
})
export class Post {
constructor() {
}
ngOnInit() {
console.log('post');
}
}
All very simple, but for some reason when I run it I get: 一切都很简单,但是由于某种原因,我得到了:
angular2-polyfills.js:127 GET http://localhost:5000/lib/spa/components/post.component 404 error angular2-polyfills.js:127 GET http:// localhost:5000 / lib / spa / components / post.component 404错误
angular2-polyfills.js:349 Error: XHR error (404 Not Found) loading http://localhost:5000/lib/spa/components/post.component (…) angular2-polyfills.js:349错误:加载http:// localhost:5000 / lib / spa / components / post.component (…)时出现XHR错误(找不到404)
Why do I get this? 为什么我得到这个? It seems it looks for the file http://localhost:5000/lib/spa/components/post.component
似乎正在寻找文件http:// localhost:5000 / lib / spa / components / post.component
when it should apply .js to the request and get http://localhost:5000/lib/spa/components/post.component.js ' 什么时候应该将.js应用于请求并获取http:// localhost:5000 / lib / spa / components / post.component.js '
EDIT: 编辑:
Solution was: 解决方案是:
<script>
System.config({
packages: {
'/lib/spa/': { defaultExtension: 'js' }
}
});
System.import('/lib/spa/app.js')
.then(null, console.error.bind(console));
</script>
The package loader system.js was not configured correctly.. 软件包加载程序system.js的配置不正确。
Your configuration is wrong. 您的配置错误。 You configured a package named
app
but your package is named lib
. 您配置了名为
app
的软件包,但将其命名为lib
。
Try: 尝试:
<script>
System.config({
packages: {
lib: {
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('lib/spa/app')
.then(null, console.error.bind(console));
</script>
