I am trying to query some data in my data. But when I send get request to my server, It's not returning anything. But when I console log my data is printed on the console. I handle all promises and other stuff. But the results are the same.

Controller method: -

  @Get('order/:state')
  async getOrderByStatus(
    @Res() response: Response,
    @Param('state') state: number,
  ): Promise<OrderService[]> {
    try {
      const orderStatus = await this.orderServiceService.getOrderByStatus(
        state,
      );
      if (orderStatus) {
        console.log(orderStatus);
        return orderStatus;
      }
    } catch (error) {
      console.log(error);
      response.status(401).send(error);
    }
  }

Service method: -

  async getOrderByStatus(state: number): Promise<OrderService[]> {
    try {
      const orderState = await this.orderModel.find({ orderStatus: state });
      if (orderState) {
        return orderState;
      }
      throw new HttpException('Order not found', HttpStatus.NOT_FOUND);
    } catch (error) {
      console.log(error);
      throw error;
    }
  }

Client-side:- (Request data is still sending.Not returning data from my controller)

I really need your help... Thank you..❤️

CodePudding user response：

When you add @Res() to the route handler, you are telling Nest that you want to use the library-specific approach and you'll handle sending the response on your own. If you don't need any underlying engine specific methods, I'd suggest not using @Res() in the route handler, and if you do need some method, but still want Nest to send the response you can end up using @Res({ passthrough: true }), just make sure that you don't end up calling res.send yourself.

For handling the error, you can catch the error and re-throw it as an HttpException, that way Nest's built-in exception filter will send the proper response code and message for you
