我之前报的错误:
When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.
网上有很多解决手法,都差不多,只需加这段代码:
List<String> allowedOriginPatterns = new ArrayList<>(); allowedOriginPatterns.add("*"); corsConfiguration.setAllowedOriginPatterns(allowedOriginPatterns);
没有用,我仔细阅读报的错误,其实已经告诉我了,是要这样改:
corsConfiguration.setAllowCredentials ( true );
改:
corsConfiguration.setAllowCredentials ( false );
完整的代理是这样的:
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.reactive.CorsWebFilter; import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource; import java.util.ArrayList; import java.util.List;
@Configuration public class GlobalCorsConfig {
@Bean public CorsWebFilter CorsWebFilter(){ UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); CorsConfiguration corsConfiguration = new CorsConfiguration (); corsConfiguration.addAllowedHeader ( "*" ); corsConfiguration.addAllowedMethod ( "*" ); corsConfiguration.addAllowedOrigin ( "*" ); corsConfiguration.setAllowCredentials ( false ); corsConfiguration.addAllowedOriginPattern("*"); // 允许访问的客户端域名 List<String> allowedOriginPatterns = new ArrayList<>(); allowedOriginPatterns.add("*"); corsConfiguration.setAllowedOriginPatterns(allowedOriginPatterns); corsConfiguration.setMaxAge(18000L);// 预检请求的缓存时间(秒),即在这个时间段里,对于相同的跨域请求不会再预检了 source.registerCorsConfiguration ( "/**" ,corsConfiguration); return new CorsWebFilter ( source ); }
}
