Angular Http拦截器不'；不要记录任何信息

我已经创建了一个

CustomHttpInterceptor

，现在我只想记录一些信息，例如：

@Injectable()
export class CustomHttpInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    console.log('http intercpeotr', req, next)
    return next.handle(req);
  }

问题是，您需要使用新的（Angular 4.3）来执行请求（从

@Angular/common/http

导入），而不是从

@Angular/http

导入的旧请求

import { HttpClient, HttpParams } from '@angular/common/http';

@Injectable()
export class MyService {
  constructor(private httpClient: HttpClient) {}

  getAllWithPaging(params: HttpParams) {
    return this.httpClient.get(this.url + '/withPaging?' + params.toString());
  }
}

有关详细指南，请参阅

import { HttpClient, HttpParams } from '@angular/common/http';

@Injectable()
export class MyService {
  constructor(private httpClient: HttpClient) {}

  getAllWithPaging(params: HttpParams) {
    return this.httpClient.get(this.url + '/withPaging?' + params.toString());
  }
}
