它在客户端渲染中工作正常。我可以看到有角的prod版本包含资产文件夹，但是Node server版本没有任何资产吗？节点服务器正在运行，并且能够呈现“索引”页面，但是未呈现图像。使用路由localhost：4000 / src / assets / image.jpg拍摄的照片更多，在“网络”标签中，状态为304。 请在下面找到我的代码：

看起来您正在混合预渲染和表达渲染代码。您需要替换：
import { renderModuleFactory } from '@angular/platform-server';
app.engine('html', (_, options, callback) => {
renderModuleFactory(AppServerModuleNgFactory, {
// Our index.html
document: template,
url: options.req.url,
// DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP)
]
}).then(html => {
callback(null, html);
});
});
使用
import { ngExpressEngine } from '@nguniversal/express-engine';
app.engine('html', ngExpressEngine({
bootstrap: AppServerModuleNgFactory,
providers: [
provideModuleMap(LAZY_MODULE_MAP)
]
}));
