POST 请求的请求资源上不存在“Access-Control-Allow-Origin”header

Question

我有一个基于 Typescript 的 React 应用程序，它托管在我的 PC 上。 我使用 Spring 网关将请求转发到另一个微服务。 GET 请求工作正常，但对于 POST 请求，我得到：

Access to XMLHttpRequest at 'http://1.1.1.1:8080/api/support/tickets/create' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Spring云配置：

@Bean
public RouteLocator routes(RouteLocatorBuilder builder, LoggingGatewayFilterFactory loggingFactory) {

    return builder.routes()
            .route("route_id",
                    route -> route
                            .path("/api/support/tickets/**")
                            .filters(f -> f.rewritePath("/api/support/tickets/(?<RID>.*)", "/support/tickets/${RID}"))
                            .uri("lb://merchant-hub-admin-service")
            )
            .build();
}

反应代码：

export async function getTicket(id: string) {
  return await axios.get(`${baseUrl}/support/tickets/ticket/${id}`);
}

export async function postTicket(
    data: TicketFullDTO
): Promise<AxiosResponse<TicketFullDTO>> {
  return await axios.post<TicketFullDTO>(
      `${baseUrl}/support/tickets/create`, data);
}

你知道我收到异常的 POST 请求可能是什么原因吗？
