Question

在所有过程之后，我都得到了预期的响应，但是失败了，错误为cant set header after they are sent

main.ts

export class GetAccountBalanceController extends Controller {
    public static async process(@Request() request: ExpressRequest,
                                response: ExpressResponse): Promise<any> {
        try {
            const instance = new GetAccountBalanceController();
            const data = await instance.execute(request, response);
            response.status(200);
            response.send(data);
        } catch (err) {
            response.status(200);
            response.send(err.message);
        }

    }
}

您将要在“发送”后面附加状态，并且应该为您清除该状态！我也将状态更改为400 ：)希望这会有所帮助！

        try {
            const instance = new GetAccountBalanceController();
            const data = await instance.execute(request, response);
            response.status(200).send(data);
        } catch (err) {
            response.status(400).send(err.message);
        }

在使用快递发送标题后，是否收到无法发送标题的错误？
