当我使用 HttpInterceptor 添加标头时，它们会添加到lazyUpdate，而不是标头数组

Question

我已经通过 Angular 中的 HttpInterceptor 添加了授权标头，但输出似乎不正确。根据添加标头后的 JSON 输出，这感觉太笨拙而无法正确。我是否错误地添加了标头，或者我访问它们是否错误？：

headers["lazyUpdate"].forEach(x=>{x.name=='Authorization'}).value

目标是回归Bearer mystring

拦截器调用：

{"url":" https://myurl ","body:{}, "reportProgress":false, "withCredentials":false, "responseType":"json", "method":"POST", "headers" :{"normalizedNames":{},"lazyUpdate":null,"headers":{}},"params":{"updates":null,"cloneFrom":null,"encoder":{},"map" :null},"urlWithParams":"myurl"}

token.interceptor.ts:13拦截器添加token:

{"url":"myurl", "body":{}, "reportProgress":false, "withCredentials":false, "responseType":"json", "method":"POST", "headers":{" NormalizedNames":{},"lazyUpdate":[ {"name":"Authorization","value":"Bearer mystring","op":"s"} ], "headers":{},"lazyInit": {"normalizedNames":{},"lazyUpdate":null,"headers":{}}},"params":{"updates":null,"cloneFrom":null,"encoder":{},"map" :{}},"urlWithParams":"myurl"}

我的 TokenInterceptor 类：

@Injectable()
export class TokenInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {   
    console.log('interceptor called: '+JSON.stringify(request))

    let r = request.clone({
      headers: request.headers.set('Authorization', `Bearer ${localStorage.getItem("id_token")}`)
    });
    console.log('interceptor added token: '+JSON.stringify(r))
    return next.handle(r);
  }
}
