跨域配置

Jsonp

#允许跨域请求的域，*代表所有
response.setHeader("Access-Control-Allow-Origin", "*");
// 指定特定域名可以访问
response.setHeader("Access-Control-Allow-Origin", "http:localhost:8080/");
#允许带上cookie请求
response.setHeader("Access-Control-Allow-Credentials","true");
#允许请求的方法，比如 GET/POST/PUT/DELETE
response.setHeader("Access-Control-Allow-Methods","*");
#允许请求的header
response.setHeader("Access-Control-Allow-Headers","*");

SpringBoot Cors

@Configuration
public class CorsConfig {
    public CorsConfig() {
    }
    @Bean
    public CorsFilter corsFilter() {
        // 1. 添加cors配置信息
        CorsConfiguration config = new CorsConfiguration();
        config.addAllowedOrigin("http://localhost:8080");
        config.addAllowedOrigin("http://shop.z.mukewang.com:8080");
        config.addAllowedOrigin("http://center.z.mukewang.com:8080");
        config.addAllowedOrigin("http://shop.z.mukewang.com");
        config.addAllowedOrigin("http://center.z.mukewang.com");
        config.addAllowedOrigin("*");
        // 设置是否发送cookie信息
        config.setAllowCredentials(true);
        // 设置允许请求的方式
        config.addAllowedMethod("*");
        // 设置允许的header
        config.addAllowedHeader("*");
        // 2. 为url添加映射路径
        UrlBasedCorsConfigurationSource corsSource = new UrlBasedCorsConfigurationSource();
        corsSource.registerCorsConfiguration("/**", config);
        // 3. 返回重新定义好的corsSource
        return new CorsFilter(corsSource);
    }
}
