我为我的 angular2 组件开发了一个解析器，它将它们呈现在我的 HTML 文件中。到目前为止，我能够将它们以 HTML 格式呈现为
import {Component} from 'angular2/core';
import {NgSwitch, NgSwitchWhen, NgSwitchDefault,NgFor} from 'angular2/common';
import {Http, Response} from 'angular2/http';
import {Observable} from 'rxjs/Rx';
@Component({
selector: 'app',
template: `
<div>
<div>
<img src={{record}} class="pull-left image-responsive" style="width:50%;">
<img src={{record}} class="pull-right image-responsive" style="width:30%;">
</div>
<div>
<img src={{record}} class="pull-right image-responsive" style="width:100%;">
</div>
<br/><br/>
<div>
<table class="table-responsive" style="width:100%;border-collapse:separate;border:solid #D8D8D8 2px;border-radius:5px;">
<tr style="background-color: grey;">
<th style="text-align:center;">{{record}}</th>
<th style="border-left:2px solid #f5821f;text-align:center;">{{record}}</th>
</tr>
<tr style="text-align:center;">
<td > </td>
<td style="border-left:2px solid #f5821f;"> </td>
</tr>
</table>
</div>
<br/>
</div>
`
})
export class App{
public record;
constructor() {
this.record="angular2";
}
}
然后我的静态 HTML 会正确生成，但是如果我像这样使用我的组件：
import {Component} from 'angular2/core';
import {NgSwitch, NgSwitchWhen, NgSwitchDefault,NgFor} from 'angular2/common';
import {Http, Response} from 'angular2/http';
import {Observable} from 'rxjs/Rx';
import {Component1} from './component_1/component_1.component';
import {Component2} from './component_2/component_2.component';
@Component({
selector: 'app',
directives: [Component1,Component2],
template: `
<div class="container">
<div class="row">
<component_1>loading...</component_1>
</div>
<div class="row">
<component_2>loading...</component_2>
</div>
</div>
`
})
export class App{
public record;
constructor() {
this.record="angular2";
}
}
然后我的组件在 HTML 中正确加载，但我的静态 HTML 没有正确生成。见下图：
组件在浏览器中加载
但是静态 HTML 没有正确生成静态 HTML 的

import * as path from 'path';
import * as express from 'express';
import * as universal from 'angular2-universal-preview';
// Angular 2
import {App} from './app/app.component'
let app = express();
let root = path.join(path.resolve(__dirname, '..'));
// Express View
app.engine('.ng2.html', universal.ng2engine);
app.set('views', __dirname);
app.set('view engine', 'ng2.html');
// Serve static files
app.use(express.static(root));
var i = 0;
// Routes
app.use('/', (req, res) => {
res.render('index_new', {App}, function(err,html){
console.log("------------------My HTML ---------\n"+(i++));
console.log(html);
console.log("------------------My HTML ----------");
res.send(html);
});
});
// Server
app.listen(3000, () => {
console.log('Listen on http://localhost:3000');
});index_new.ng2.html
