错误 DOMException：无法在 'Document' 上执行 'querySelector'

Question

我正在尝试使用 Angular 6 应用程序设置 Adal。我遵循这些说明：

错误 DOMException：无法在 'Document' 上执行 'querySelector'：'#id_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1....

在我的重定向页面中，Azure AD 回调似乎有效：

 ngOnInit() {
   console.log("AuthRedirect: calling handle window");
   this.adal.handleWindowCallback();
   console.log("AuthRedirect: calling handle window ended");
   console.log(this.adal.userInfo.token);
   console.log(this.adal.userInfo.authenticated);
 }

我不确定这是 ADAL 异常还是路由器对回调中处理的参数不满意。欢迎所有建议。

--------------------回答------------------ 我不记得我是如何解决这个问题的，但这是一个可行的解决方案。

身份验证拦截器：

import { Injectable } from '@angular/core';
import { HttpEvent,HttpHandler,HttpRequest,HttpInterceptor } from '@angular/common/http';
import { AdalService } from 'adal-angular4';
import { Observable } from 'rxjs';


@Injectable()
export class AuthenticationInterceptor implements HttpInterceptor {
    constructor(private adalService: AdalService) { }

    intercept(req: HttpRequest<any>, next:HttpHandler): Observable<HttpEvent<any>>{
        const authHeader = this.adalService.userInfo.token;
        var header = 'Bearer ' + authHeader;
        const authReq = req.clone({headers: req.headers.set('Authorization', header)});
        return next.handle(authReq);
    }

}

AuthenticationGuard：

import { Injectable } from '@angular/core';
import { Router, CanActivate,  ActivatedRoute, RouterStateSnapshot, ActivatedRouteSnapshot} from '@angular/router';
import { AdalService } from 'adal-angular4';

@Injectable()
export class AuthenticationGuard implements CanActivate {
  constructor(private adal: AdalService, private route: ActivatedRoute) { }

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {

    if (this.adal.userInfo.authenticated) {
      return true;
    }

    console.log("Adal Login");
    var url = state.url;
    console.log(url);
    sessionStorage.setItem("adal.return.url",url);
    this.adal.login();

    return false;
  }

我的 Azure AD B2C 设置遇到了这个问题。如果有人遇到这个问题，请尝试将 response_mode=query 添加到您的 oauth url.

示例url 生成器函数

export function b2cLoginUrl() {
    return `https://${appConfig.directory}.b2clogin.com/${appConfig.directory}.onmicrosoft.com/oauth2/v2.0/authorize?p=${appConfig.signin_signup_userflow}&client_id=${appConfig.client_id}&nonce=${appConfig.nonce}&redirect_uri=${appConfig.redirect_uri}&scope=${appConfig.scope}&response_type=${appConfig.response_type}&prompt=${appConfig.prompt}&response_mode=${appConfig.response_mode}`
}
