Angular2-找不到名称-构造函数、公用、路由器

我正在尝试配置auth0 API。最后我做到了，昨天它成功了。今天不是，但我没有改变任何代码，我在WebStorm中有文件历史记录

看来问题出在你身上

构造函数（公共路由器：路由器）

这是我的配置：

@angular/cli: 1.0.0
node: 7.7.3
os: win32 x64
@angular/common: 2.4.10
@angular/compiler: 2.4.10
@angular/core: 2.4.10
@angular/forms: 2.4.10
@angular/http: 2.4.10
@angular/platform-browser: 2.4.10
@angular/platform-browser-dynamic: 2.4.10
@angular/router: 3.4.10
@angular/cli: 1.0.0
@angular/compiler-cli: 2.4.10

auth.service.ts

import { Injectable }      from '@angular/core';
import { tokenNotExpired } from 'angular2-jwt';
import { myConfig }        from './auth.config';

// Avoid name not found warnings
declare var Auth0Lock: any;

@Injectable()
export class Auth {
  // Configure Auth0
  lock = new Auth0Lock(myConfig.clientID, myConfig.domain, {});

  constructor() {
    // Add callback for lock `authenticated` event
    this.lock.on("authenticated", (authResult) => {
      localStorage.setItem('id_token', authResult.idToken);
    });
  }

  public login() {
    // Call the show method to display the widget.
    this.lock.show();
  }

  public authenticated() {
    // Check if there's an unexpired JWT
    // This searches for an item in localStorage with key == 'id_token'
    return tokenNotExpired('id_token');
  }

  public logout() {
    // Remove token from localStorage
    localStorage.removeItem('id_token');
  }
}

import { Router, NavigationStart } from '@angular/router';
import 'rxjs/add/operator/filter';

constructor(public router: Router) {
  this
    .router
    .events
    .filter(event => event instanceof NavigationStart)
    .filter((event: NavigationStart) => (/access_token|id_token|error/).test(event.url))
    .subscribe(() => {
      this.lock.resumeAuth(window.location.hash, (error, authResult) => {
        if (error) return console.log(error);
        localStorage.setItem('id_token', authResult.idToken);
        this.router.navigate(['/']);
      });
    });
}

这是console抛出的内容：

ERROR in C:/xampp/htdocs/untitled/SmartHome/src/app/auth.service.ts (40,20): ',' expected.
C:/xampp/htdocs/untitled/SmartHome/src/app/auth.service.ts (40,26): ',' expected.

You may need an appropriate loader to handle this file type.

有人能帮忙吗？

此代码错误：

import { Router, NavigationStart } from '@angular/router';
import 'rxjs/add/operator/filter';

constructor(public router: Router) {
  this
    .router
    .events
    .filter(event => event instanceof NavigationStart)
    .filter((event: NavigationStart) => (/access_token|id_token|error/).test(event.url))
    .subscribe(() => {
      this.lock.resumeAuth(window.location.hash, (error, authResult) => {
        if (error) return console.log(error);
        localStorage.setItem('id_token', authResult.idToken);
        this.router.navigate(['/']);
      });
    });
}

错误消息：

| import { Router, NavigationStart } from '@angular/router';
| import 'rxjs/add/operator/filter';
| constructor(public, router, Router);
| {
|     this

所以构造函数必须属于一个类，而不是独立类

例如：

export class YouClassService {
  constructor(public router: Router) {}
}

此代码错误：

import { Router, NavigationStart } from '@angular/router';
import 'rxjs/add/operator/filter';

constructor(public router: Router) {
  this
    .router
    .events
    .filter(event => event instanceof NavigationStart)
    .filter((event: NavigationStart) => (/access_token|id_token|error/).test(event.url))
    .subscribe(() => {
      this.lock.resumeAuth(window.location.hash, (error, authResult) => {
        if (error) return console.log(error);
        localStorage.setItem('id_token', authResult.idToken);
        this.router.navigate(['/']);
      });
    });
}

错误消息：

| import { Router, NavigationStart } from '@angular/router';
| import 'rxjs/add/operator/filter';
| constructor(public, router, Router);
| {
|     this

所以构造函数必须属于一个类，而不是独立类

例如：

export class YouClassService {
  constructor(public router: Router) {}
}

如果将类构造函数和属性分离到

public router:router；构造函数（_router:router）{this.router=_router；}

？未更改：找不到名称“_router”。如果将类构造函数和属性分离到

公共路由器：router；构造函数（_router:router）{this.router=_router；}

？未更改：找不到名称“_router”。
