Provisional headers are shown错误

使用chrome谷歌浏览器前后端接口调试的时候遇到了这个问题:
network

Provisional headers are shown

console

Cross-Origin Read Blocking (CORB) blocked cross-origin response http://xxx:180/test?id=1035 with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.

如果使用其它浏览器或者postman等测试工具测试的话又可以调用。

错误原因其实是跨域的问题,后端需要设置允许跨域就可以了。

我的项目是spring boot项目,配置跨域如下:

@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig() {
        org.springframework.web.cors.CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("http://127.0.0.1:800"); // 1这就是前端调用放的origin,可以在network中查看
        corsConfiguration.addAllowedHeader("*"); // 2允许任何头
        corsConfiguration.addAllowedMethod("*"); // 3允许任何方法(post、get等)
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig()); // 4
        return new CorsFilter(source);
    }
}
