将令牌从Angular2发送到java筛选器时出现问题

我正在尝试通过服务HTTP的GET方法发送令牌，但请求头中没有auth令牌的值（存储在浏览器localStorage中用于身份验证控制的令牌）

以下是请求的标题：

Accept:*/* Accept-Encoding:gzip, deflate, sdch, br Accept-Language:pt-BR,pt;q=0.8,en-US;q=0.6,en;q=0.4 Access-Control-Request-Headers:auth-token, content-type Access-Control-Request-Method:GET Connection:keep-alive Host:localhost:7005 Origin:http://localhost:4200 Referer:http://localhost:4200/ User-Agent:Mozilla/5.0 (Windows NT
6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

我需要在Access Control Request Headers参数之外对令牌进行身份验证，才能访问身份验证令牌值：

下面是我的代码（2）

代码：

    export class BaseProvider {
        protected static HOST: string = 'http://localhost:7005/'
        protected static BASE_API: string = 'context';

         protected headers = new Headers({
            'Content-Type': 'application/json',
            'auth-token': localStorage.getItem('user-token')
        });

     protected options = new RequestOptions({ headers: this.headers });

     protected static getBaseAPI(): string {
        return this.HOST + this.BASE_API;
    }
}

@Injectable()
export class MyService extends BaseProvider {

  constructor(private http: Http) {
    super();
  }

  public findByName(obj: MyModel): Observable<Array<MyModel>> {
    let params: URLSearchParams = new URLSearchParams();
    params.set('name', obj.name);
    this.options.search = params;

    return this.http.get(BaseProvider.getBaseAPI() + myUrl, this.options)
      .map((res: Response) => res.json()
      ).catch((error: any) => Observable.throw(error.json().error || 'Error!'));
  }
}

Java代码的“authHeaderVal”变量没有使用令牌填充，因为“auth令牌”为空

如果没有LoginFilter类，请求将按如下方式到达：

Accept:application/json, text/plain, */*
Accept-Encoding:gzip, deflate, sdch, br
Accept-Language:pt-BR,pt;q=0.8,en-US;q=0.6,en;q=0.4

我需要请求在启动时到达筛选器。

在引发异常之前，是否可以打印请求的所有标头？是，但身份验证令牌密钥位于访问控制请求标头内，我无法获取值。

Accept:application/json, text/plain, */*
Accept-Encoding:gzip, deflate, sdch, br
