Spring webflux：将 http 重定向到 https

Question

如何在 spring webflux 中配置 http->https 重定向？我需要将所有 http 请求重定向到 https（据我所知，任何 http 请求都应具有 301 http 状态响应并更改 http->https）。在 documentation 中未找到有关它的任何信息。我找到了这个 answer，但它与 tomcat 有关。我有网络

找到方法了，希望对大家有帮助：

@Bean
public WebFilter httpsRedirectFilter() {
    return new WebFilter() {
        @Override
        public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
            URI originalUri = exchange.getRequest().getURI();

            //here set your condition to http->https redirect
            List<String> forwardedValues = exchange.getRequest().getHeaders().get("x-forwarded-proto");
            if (forwardedValues != null && forwardedValues.contains("http")) {
                try {
                    URI mutatedUri = new URI("https",
                            originalUri.getUserInfo(),
                            originalUri.getHost(),
                            originalUri.getPort(),
                            originalUri.getPath(),
                            originalUri.getQuery(),
                            originalUri.getFragment());
                    ServerHttpResponse response = exchange.getResponse();
                    response.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
                    response.getHeaders().setLocation(mutatedUri);
                    return Mono.empty();
                } catch (URISyntaxException e) {
                    throw new IllegalStateException(e.getMessage(), e);
                }
            }
            return chain.filter(exchange);
        }
    };
}

我设法让它与以下内容一起使用。但是，我怀疑这是否受支持，将来可能会导致问题。

@Configuration
public class HttpToHttpsRedirectConfig {

    @PostConstruct
    public void startRedirectServer() {
        NettyReactiveWebServerFactory httpNettyReactiveWebServerFactory = new NettyReactiveWebServerFactory(8080);
        httpNettyReactiveWebServerFactory.getWebServer((request, response) -> {
            URI uri = request.getURI();
            URI httpsUri;
            try {
                httpsUri = new URI("https", uri.getUserInfo(), uri.getHost(), 8443, uri.getPath(), uri.getQuery(), uri.getFragment());
            } catch (URISyntaxException e) {
                return Mono.error(e);
            }
            response.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
            response.getHeaders().setLocation(httpsUri);
            return response.setComplete();
        }).start();
    }

}
