我正在服务器上渲染一个有角度的应用程序,并且试图将字符串值注入到我的服务中,它在服务器上可以正常工作,但在浏览器上该值为null。有什么想法可以做到这一点吗?
server.ts:
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),
{provide: "clientIp", useValue: "129.112.28.171", deps: []}
]
})
服务:
@Injectable({
providedIn: 'root'
})
export class GeoService {
constructor(@Inject("clientIp") @Optional() protected clientIp: string) {
// clientIp is "129.112.28.171" on the server but null on the client/browser
}
}
如何在浏览器中访问值?
