typescript - 错误 TS2339 : Property 'do' does not exist on type 'Observable

Question

我使用的是 angular-5.x，一旦升级到 angular-6.x 及其对等依赖项(zone、rxjs 等)。

我开始面临以下错误

ERROR in src/app/xxx/apiConnection/auth.interceptor.ts(25,33): error TS2339: Property 'do' does not exist on type 'Observable>'. src/app/xxx/apiConnection/auth.interceptor.ts(30,31): error TS2339: Property 'do' does not exist on type 'Observable>'.

我的代码如下:

intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    console.log(req)
    if(!req.headers.has('skip-interceptors')) {
      let card = localStorage.getItem(LocalStoregeIdems.oAUTH_ACCESS_CARD)
        , headers;
      if (card) {
        headers = req.headers.set('Authorization', card);
      }

      let clone = req.clone({
            withCredentials: true,
            headers
          });
      return next.handle(clone).do(event => {
        console.log(event);
      });
    } else {
      req.headers.delete('skip-interceptors');
      return next.handle(req).do(event => {
        console.log(event);
      });
    }
  }

do 运算符在 rxjs6 中已重命名为 tap 运算符。

希望对你有帮助
