前端請(qǐng)求報(bào)錯(cuò)：Access to XMLHttpRequest at 'http://xxx.xx.xx.xx:xx/api/*?param=' from origin 'http://xxx:xxx' 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.
解決方案：在SpringBoot中添加以下 配置：
@Configuration
public class GlobalCorsConfig {
@Bean
public CorsFilter corsFilter() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.setAllowCredentials(true);
corsConfiguration.addAllowedOrigin("*");
corsConfiguration.addAllowedHeader("*");
corsConfiguration.addAllowedMethod("*");
UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
return new CorsFilter(urlBasedCorsConfigurationSource);
}
}
