在Angular 8中,可以通过使用Angular的RouterModule来将配置传递给延迟加载的模块。下面是一个示例解决方案:
export const config = {
apiUrl: 'https://api.example.com',
apiKey: 'abc123'
};
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule } from '@angular/router';
import { config } from './config';
@NgModule({
declarations: [],
imports: [
CommonModule,
RouterModule.forChild([
{
path: '',
component: LazyComponent,
data: config // 传递配置
}
])
]
})
export class LazyModule { }
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule } from '@angular/router';
import { config } from './config';
@NgModule({
declarations: [],
imports: [
BrowserModule,
RouterModule.forRoot([
{
path: 'lazy',
loadChildren: './lazy/lazy.module#LazyModule',
data: config // 传递配置
}
])
],
bootstrap: [AppComponent]
})
export class AppModule { }
现在,当延迟加载模块被加载时,配置将传递给该模块。在延迟加载模块中,可以通过在路由数据中访问配置来使用它。例如,lazy.component.ts文件:
import { Component } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
@Component({
selector: 'app-lazy',
template: `
Lazy Component
API URL: {{ apiUrl }}
API Key: {{ apiKey }}
`
})
export class LazyComponent {
apiUrl: string;
apiKey: string;
constructor(private route: ActivatedRoute) {
this.apiUrl = this.route.snapshot.data.apiUrl;
this.apiKey = this.route.snapshot.data.apiKey;
}
}
这样,延迟加载模块中的LazyComponent组件将使用配置中的值进行渲染。
