Javascript 部署到Google App Engine时未找到Express可选路由

我在Express服务中为路线添加了一个新的可选参数。所有东西都在本地工作，但是当部署到Google App Engine时，当提供可选参数时，我的服务将返回not found

主服务器启动：

const indexRouter: express.Router = cradle.indexRouter; // from dependency injection
const server = express();
server.disable("x-powered-by");
server.use(responseTime(responseTimeLogger(logger)));
const port = process.env.PORT || 3000;
server.listen(port, () => {
      logger.info(`Express server has started on port ${port}`);
      server.use("/api/v1/", indexRouter);
      resolve();
});

bradle.indexRouter

->

createIndexRouter

：

function createIndexRouter(services: IIndexRouterArgs) {
  const indexRouter = Router();

  indexRouter.use("/weather", services.weatherRouter);
  indexRouter.use("/health", services.healthRouter);
  indexRouter.use("*", notFoundMiddleware);

  return indexRouter;
}

function createWeatherRouter(services: IWeatherRouterArgs) {
  const weatherRouter = Router();

  weatherRouter.get(
    "/:latitude/:longitude/:postalCode?",
    services.weatherController.reportWeather
  );

  return weatherRouter;
}

services.weatherRouter

->

createWeatherRouter

：

function createIndexRouter(services: IIndexRouterArgs) {
  const indexRouter = Router();

  indexRouter.use("/weather", services.weatherRouter);
  indexRouter.use("/health", services.healthRouter);
  indexRouter.use("*", notFoundMiddleware);

  return indexRouter;
}

function createWeatherRouter(services: IWeatherRouterArgs) {
  const weatherRouter = Router();

  weatherRouter.get(
    "/:latitude/:longitude/:postalCode?",
    services.weatherController.reportWeather
  );

  return weatherRouter;
}

请求

https://{service}.com/api/v1/weather/50/50/10001

时，我希望点击

services.weatherController.reportWeather

，但由于10001（postalCode）参数，我将被路由到

notFoundMiddleware

。删除它会返回成功的响应。

您请求的url是什么？https://{service}.com/api/v1/weather/50/50/10001/api/v1来自哪里？您需要发布刚刚更新的完整设置和一些附加信息如果您使用console.log

req.params
