webflux开启CORS的样例代码

在Spring WebFlux中，可以使用WebFilter来开启CORS，样例代码如下：@Bean
public WebFilter corsFilter() {
return (ServerWebExchange ctx, WebFilterChain chain) -> {
ServerHttpRequest request = ctx.getRequest();
if (CorsUtils.isCorsRequest(request)) {
HttpHeaders requestHeaders = request.getHeaders();
ServerHttpResponse response = ctx.getResponse();
HttpMethod requestMethod = requestHeaders.getAccessControlRequestMethod();
HttpHeaders headers = response.getHeaders();
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_ORIGIN, requestHeaders.getOrigin());
headers.addAll(HttpHeaders.ACCESS_CONTROL_ALLOW_HEADERS, requestHeaders.getAccessControlRequestHeaders());
if (requestMethod != null) {
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_METHODS, requestMethod.name());
}
headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_CREDENTIALS, "true");
headers.add(HttpHeaders.ACCESS_CONTROL_EXPOSE_HEADERS, "all");
headers.add(HttpHeaders.ACCESS_CONTROL_MAX_AGE, "3600");
if (request.getMethod() == HttpMethod.OPTIONS) {
response.setStatusCode(HttpStatus.OK);
return Mono.empty();
}
}
return chain.filter(ctx);
};
}
