推荐答案
我使用此自定义过滤器取得了成功:
I had success with this custom filter:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.web.cors.reactive.CorsUtils;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;
@Configuration
public class CorsConfiguration {
private static final String ALLOWED_HEADERS = "x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN";
private static final String ALLOWED_METHODS = "GET, PUT, POST, DELETE, OPTIONS";
private static final String ALLOWED_ORIGIN = "*";
private static final String MAX_AGE = "3600";
@Bean
public WebFilter corsFilter() {
return (ServerWebExchange ctx, WebFilterChain chain) -> {
ServerHttpRequest request = ctx.getRequest();
if (CorsUtils.isCorsRequest(request)) {
ServerHttpResponse response = ctx.getResponse();
HttpHeaders headers = response.getHeaders();
headers.add("Access-Control-Allow-Origin", ALLOWED_ORIGIN);
headers.add("Access-Control-Allow-Methods", ALLOWED_METHODS);
headers.add("Access-Control-Max-Age", MAX_AGE);
headers.add("Access-Control-Allow-Headers",ALLOWED_HEADERS);
if (request.getMethod() == HttpMethod.OPTIONS) {
response.setStatusCode(HttpStatus.OK);
return Mono.empty();
}
}
return chain.filter(ctx);
};
}
}
和 org.springframework.boot:spring-boot-starter-web
不应包含在依赖项中 - 过滤器不能用于它。
and org.springframework.boot:spring-boot-starter-web
should not be included as dependency - filter does not work with it.
