Angular 9 - 打字稿 - headers.set - 不添加 header

Angular 9 - typescript - headers.set - not adding header

我尝试使用 angular 注入器来添加不记名令牌

虽然代码执行了,但是header没有添加

那里有很多不同的代码,我尝试了其中一些,它们都导致了同样的问题

请求

没有发送者

在下图中,我在 clone/headers.set 处停了下来,但是 即使在那一步之后,headers 地图是还是空的

@Injectable()
export class JwtInterceptor implements HttpInterceptor {
  constructor(
    private appService: AppService
  ) { }

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // add auth header with jwt if user is logged in and request is to the api url
    let authentication: Authentication = this.appService.getUserSession();

    const isLoggedIn = authentication && authentication.token;
    const isApiUrl = request.url.startsWith(environment.apiUrl);

    //------------------------------------- add id's
    let body = request.body;
    if(!body)
    {
        body={};
    }
    body['clientId'] = environment.clientId;
    body['clientSecret'] = environment.clientSecret;

    request = request.clone({
        body: body
    });

    //--------------------------------------- add jwt

    if(authentication)
    {
        request = request.clone(
            {
                headers: request.headers.set('Bearer', authentication.token)
            }
        );
    }

    return next.handle(request);
  }
}

感谢你在这方面帮助我

根据 clone() 方法原型,你得到了一个 object 属性 来设置 headers (名为 setHeaders)

setHeaders?: {
            [name: string]: string | string[];
        };

您应该按照以下步骤进行

 request = request.clone(
         {
            setHeaders: {
                Authorization: `Bearer ${authentication.token}`
            }
         }
    );
