Angular 4:Build to prod:属性是私有的,只能在类中访问

Question

我正在使用Angular 4,我正在运行: ng build --prod

我抓住了这个:

ng build --prod
Your global Angular CLI version (1.2.2) is greater than your local
version (1.0.0). The local Angular CLI version is used.

To disable this warning use "ng set --global warnings.versionMismatch=false".

Component'.

ERROR in ng:///D:/Sources/DotNet/NextGCClientWeb/src/app/login/login.component.html (11,3): Property 'activatedRoute' is private and only accessible within class 'Login

这个错误似乎很奇怪:

ERROR in 
    ng:///D:/Sources/DotNet/NextGCClientWeb/src/app/login/login.component.html (11,3): Property 'activatedRoute' is private and only accessible within class 'Login Component

错误中指示的组件如下:

import { Component } from '@angular/core';
import { Router, ActivatedRoute, Params } from '@angular/router';
import { Http, Response } from '@angular/http';
import { SessionService } from './../../shared/service';

import { User } from './../../model';

@Component({
  selector: 'login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})
export class LoginComponent {
  error: string;
  email: string;
  password: string;
  stayConnected: Boolean;

  constructor (
    private sessionService: SessionService,
    private router: Router,
    private activatedRoute: ActivatedRoute
  ) {
    if (activatedRoute.snapshot.params['keyWording']) {
      this.sessionService.logInWithFinalization(activatedRoute.snapshot.params['keyWording']);
    }
  }

  logIn() {
    this.sessionService.logIn(this.email, this.password, this.stayConnected).subscribe(
      () => {
        if (this.sessionService.pageRequestedInUnauthenticated == null) {
          this.router.navigate(['/welcome']);
        } else {
          this.router.navigate([this.sessionService.pageRequestedInUnauthenticated]);
        }
      },
      (error: Response) => this.error = error.json()
    );
  }
}

html视图:

<div id="divLogin">
  <h1>Se connecter</h1><br>
  <i class="fa fa-envelope-o fa-lg" id="iconEmail"></i>
  <input type="text" id="email" [(ngModel)]="email" (keyup.enter)="logIn()" class="form-control" placeholder="Adresse email" autofocus />
  <i class="fa fa-lock fa-lg" id="iconPassword"></i>
  <input type="password" id="password" [(ngModel)]="password" (keyup.enter)="logIn()" class="form-control" placeholder="Mot de passe" />
  <button (click)="logIn()" class="btn btn-primary btn-block btn-lg">Connexion</button>
  <span id="containerStayConnected" title="Non implémenté"><input type="checkbox" id="stayConnected" [(ngModel)]="stayConnected" /><label for="stayConnected">Restez connecté</label></span>
  <a id="forgetPassword" title="Non implémenté">Mot de passe oublié</a><br><br><br>
  <a routerLink="/inscription">S'inscrire</a><br>
  {{ error }}
</div>

<div class="confirmationMessage" *ngIf="activatedRoute.snapshot.params['keyWording'] == 'validateInscription'"><br>Un lien de confirmation vous a été envoyé sur votre boîte email afin de valider votre compte. Merci.</div>

<div id="piedDePage"></div>

当运行服务时,我没有抓住它.

任何命题？

Answer 1

更改为public activatedRoute

你需要制作你的activatedRoute public.这是在使用aot进行生产时的清单.(取自这个github项目https://github.com/asadsahi/AspNetCoreSpa,虽然它适用于任何其他角度项目.)

AOT - 提前编译不要

• 不要对模板或样式使用require语句,使用styleUrls和templateUrls,angular2-template-loader插件会在构建时将其更改为require.

• 不要使用默认导出.

• 不要使用form.controls.controlName,使用form.get('controlName')

• 不要使用control.errors？.someError,使用control.hasError('someError')

• 不要在提供者,路由或声明中使用函数,导出函数然后引用函数名称输入,输出,视图或内容子(ren),Hostbindings,以及您在模板中使用的任何字段或Angular的注释应该是上市

保持activatedRoute私密

要将您的activatedRoute保密,您可以执行以下操作

theData:any;
constructor (
private sessionService: SessionService,
private router: Router,
private activatedRoute: ActivatedRoute
 ) {
     this.activatedRoute.params.subscribe(
      params => {
        this.theData= params['keyWorking']; 
        //you will bind the theData instead of the activatedROute
      }
    );
}

}

并在您的模板中

<div class="confirmationMessage" *ngIf="theData == 'validateInscription'">
<br>Un lien de confirmation vous a été envoyé sur votre boîte email afin de 
 valider votre compte. Merci.</div>
