Angular 编译过程中最新rxjs出错

我是angular的新手，我正在尝试将angular 4升级为最新的angular， 我试图使可重用的类方法，在许多服务和组件上使用它

假设此文件名为：

./base-services.services.ts：

我使用这些基本服务来扩展我提供的所有服务

./getData.services.ts：

在组件上：

updateValue() {
    this.legalOrderService.getCart().subscribe(response => {
      if (response.message != "ERROR") {
        this.localStorageService.store("legalOrder", response.result);
        this.localStorageService.store(
          "cartItems",
          response.result.order_details
        );
        this.cartTotal = this.localStorageService.retrieve("cartItems");
      }
    });
  }

在服务的组件上使用subscribe是否有错

在这之后，我得到如下错误：

    node_modules/rxjs/internal/Subscription.d.ts(17,3): error TS2393: Duplicate function implementation.

我在代码中看到的一个问题是，您不需要多次订阅，只需从getDataParam方法中删除订阅，因为您已经在组件中订阅了

getDataParam(url: any, params: any) {
    return this.http
      .get(url, { params: params })
      .pipe(catchError(this.handleError));
  }

您正在尝试订阅以下订阅：

首先尝试在getDataParam中订阅 然后尝试在updateValue中再次订阅 从getDataParam中删除订阅：

所以我不应该订阅那个可重用类？然后把它订阅到一个组件中？@ZumDummi不。只要订阅你的组件就行了component@ZumDummi您可以在可重用类上应用其他操作符，如map，而不是subscribe，您可以给我一个在可恢复类上使用map的示例吗？@ZumDummi like this return this.http.posturl，data.pipemapres=>res，catchErrorthis.HandleErrors我不应该订阅那个可重用类吗？然后把它订阅到一个组件中？是的。为组件获取数据时，订阅组件是一个很好的经验法则。我们是否也应该使用map？您希望映射什么？以获得json结果
