我需要创建效果，它将在时间间隔内使用 refresh-token 刷新访问令牌

Question

我想创建在用户成功登录后按时间间隔刷新令牌的效果，我还需要 select 来自商店的 refreshToken，这对我来说开始太复杂了，我想不通弄清楚怎么做。

到目前为止的效果

  @Effect()
  refreshAccessToken$ =
    this.actions$.pipe(
      ofType(AccountActionsTypes.AccountLoginSuccess),
      map(() => {
        interval(5000)
          .pipe(
            mapTo(() => this.store
              .pipe(
                select(selectRefreshToken),
                map(refreshToken => {
                  if (refreshToken != '' && refreshToken != undefined) {
                    this.accountService.refreshToken(refreshToken)
                      .pipe(
                        map((response: { token: string }) => {
                          return {type: AccountActionsTypes.RefreshTokenSuccess, token: response.token};
                        })
                      );
                  } else {
                    return {type: AccountActionsTypes.RefreshTokenSuccess, token: ''};
                  }
                })
              )));
      }));

但是我得到这个错误

也许有人会觉得这有帮助，这是建议修复的效果：

@Effect()
  refreshAccessToken$ =
    this.actions$.pipe(
      ofType(AccountActionsTypes.AccountLoginSuccess),
      switchMap(() => {
        return interval(5000)
          .pipe(
            switchMap(() => this.store
              .pipe(
                select(selectRefreshToken),
                switchMap((refreshToken) => this.accountService.refreshToken(refreshToken)
                  .pipe(
                    map((response: { token: string, status: string }) => {
                      if (response.token !== undefined) {
                        return {
                          type: AccountActionsTypes.RefreshTokenSuccess,
                          token: response.token,
                        };
                      } else {
                        return {type: AccountActionsTypes.RefreshTokenWrong, status: response.status};
                      }
                    })
                  ))
              )));
      }));

如果你想 return 一个内部可观察对象，你必须使用展平运算符：

 @Effect()
  refreshAccessToken$ =
    this.actions$.pipe(
      ofType(AccountActionsTypes.AccountLoginSuccess),
      // 
      switchMap(() => { ... })

我需要创建效果，它将在时间间隔内使用 refresh-token 刷新访问令牌

I need to create effect which will in time intervals refresh access token with refresh-token

ngrx

refresh-token
