renren开源里跨域出现access control Allow Origin的问题

本文主要是介绍renren开源里跨域出现access control Allow Origin的问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

人人开源的文件中已经有了一个跨域

自己重新搞一个跨域要把这个删掉or注释

package io.renren.config;import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class CorsConfig implements WebMvcConfigurer {
//
//    @Override
//    public void addCorsMappings(CorsRegistry registry) {
//        registry.addMapping("/**")
//            .allowedHeaders("access control Allow Origin")
//            .allowedOrigins("http://localhost:8001")
//            .allowCredentials(true)
//            .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
//            .maxAge(3600);
//    }
}

重新搞一个跨域

package com.rod.bishe.bishegateway.config;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;@Configuration
public class BisheCorsConfiguration {@Beanpublic CorsWebFilter corsWebFilter() {UrlBasedCorsConfigurationSource source =new UrlBasedCorsConfigurationSource();CorsConfiguration configuration = new CorsConfiguration();//配置跨域 Access-Control-Allow-Originconfiguration.addAllowedHeader("*");//这里要写具体的跨域的前端url不要写*configuration.addAllowedOrigin("http://localhost:8001");configuration.addAllowedMethod("*");configuration.setAllowCredentials(true);source.registerCorsConfiguration("/**", configuration);return new CorsWebFilter(source);}
}
