首先,确保已经在项目中安装了@ngx-translate/core和@ngx-translate/http-loader依赖。然后,在AppComponent的构造函数中导入TranslateService并初始化它,以便在整个应用程序中使用翻译服务。
接下来,在authenticator组件的构造函数中导入TranslateService,并使用翻译服务的get方法将需要翻译的文本键传递给它。例如:
import { Component, OnInit } from '@angular/core'; import { TranslateService } from '@ngx-translate/core'; import { AmplifyService } from 'aws-amplify-angular';
@Component({ selector: 'app-authenticator', templateUrl: './authenticator.component.html', styleUrls: ['./authenticator.component.css'] }) export class AuthenticatorComponent implements OnInit {
constructor(private amplifyService: AmplifyService, private translateService: TranslateService) { }
ngOnInit() { this.amplifyService.auth().currentAuthenticatedUser().then(console.log).catch(console.error); this.translateService.get('CODE_INPUT').subscribe(data => { console.log(data); }); }
}
最后,确保在项目中正确地配置了TranslateLoader。在app.module.ts文件中,引入HttpClientModule并在imports数组中添加它。然后,导入TranslateLoader和HttpLoaderFactory函数,并将它们设置为providers数组中的提供程序。例如:
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { HttpClientModule, HttpClient } from '@angular/common/http'; import { TranslateModule, TranslateLoader } from '@ngx-translate/core'; import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { AppComponent } from './app.component';
export function HttpLoaderFactory(http: HttpClient) { return new TranslateHttpLoader(http); }
@NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, HttpClientModule, TranslateModule.forRoot({ loader: { provide: TranslateLoader, useFactory: HttpLoaderFactory, deps: [HttpClient] } }) ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
通过以上步骤,就能够正常使用Amplify UI Angular authenticator的翻译功能了。
