Angular2 RxJS 5.01升级TimeoutSubscriber报错

Question

当我将 RxJS 从 5.0.0-rc.4 升级到 5.0.1 时，我的 HTTP 单元测试失败并显示 ..

TimeoutSubscriber

代码适用于 5.0.0-rc.4

这是失败的代码。任何想法表示赞赏。

  private getHttpStream$(emit: any, url: string, httpResponseMapCallback: any, method: string) {
    return this.http[method](url, emit, this.options)
      .timeout(Config.http.timeout, new Error('timeout'))

      .map((response: any) => {
        if (response.status && !response.status.toString().startsWith(2)) {
          return response;
        }
        // within the callback, emit provides access to the data emitted
        return httpResponseMapCallback({emit, response});
      })

      .catch((err: any) => {
        // Different code flow in real code v unit test code
        /* istanbul ignore next */
        if (err.status && err.statusText) {
          return Observable.from([err]);
        }

        return Observable.from([err.message]);
      });
  }

从 beta/rc 到最终版本

的 .timeout(timeout, customErr, scheduler) 重载和自定义错误 has been removed. It was one of the last changes

将您的代码更改为：

return this.http[method](url, emit, this.options)
  .timeout(Config.http.timeout)

或者如果您需要自定义错误：

return this.http[method](url, emit, this.options)
  .timeout(Config.http.timeout)
  .catch(err => err instanceof Rx.TimeoutError ? Rx.Observable.throw(new MyCustomError()) : Rx.Observable.throw(err))
