在不使用发现文档的情况下，你可以手动配置Angular OIDC库的代码流程。以下是一个简单的示例：

1. 安装angular-oidc库：

npm install angular-oidc-client

2. 在Angular应用的根模块中导入所需的模块：

import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { AuthModule, OidcConfigService, OidcSecurityService, OpenIDImplicitFlowConfiguration } from 'angular-oidc-client';

@NgModule({
  imports: [
    HttpClientModule,
    AuthModule.forRoot()
  ],
  providers: [
    OidcConfigService,
    OidcSecurityService,
    {
      provide: HTTP_INTERCEPTORS,
      useClass: AuthInterceptor,
      multi: true
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

3. 在应用的配置文件中手动配置OIDC：

import { OidcConfigService } from 'angular-oidc-client';

export function configureAuth(oidcConfigService: OidcConfigService) {
  return () => {
    oidcConfigService.withConfig({
      stsServer: 'https://your-auth-server.com',
      redirectUrl: window.location.origin,
      clientId: 'your-client-id',
      scope: 'openid profile',
      responseType: 'code',
      silentRenew: true,
      silentRenewUrl: `${window.location.origin}/silent-renew.html`,
      postLogoutRedirectUri: window.location.origin + '/index.html',
      forbiddenRoute: '/forbidden',
      unauthorizedRoute: '/unauthorized',
      autoUserinfo: true,
      logLevel: 0
    });
  };
}

4. 在应用的入口组件中加载配置：

import { Component, OnInit, APP_INITIALIZER } from '@angular/core';
import { OidcConfigService } from 'angular-oidc-client';

@Component({
  selector: 'app-root',
  template: ``
})
export class AppComponent implements OnInit {
  constructor(private oidcConfigService: OidcConfigService) { }

  ngOnInit() {
    this.oidcConfigService.onConfigurationLoaded()
      .subscribe(() => {
        // OIDC配置加载完成后执行其他初始化操作
      });
  }
}

@NgModule({
  declarations: [AppComponent],
  imports: [/* 其他模块 */],
  providers: [
    {
      provide: APP_INITIALIZER,
      useFactory: configureAuth,
      deps: [OidcConfigService],
      multi: true
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

通过以上步骤，你可以在不使用发现文档的情况下手动配置Angular OIDC库的代码流程。请确保根据你的实际情况修改配置。
