go、spring boot、vert.x 用CORS解决跨域

go gin 使用github.com/gin-contrib/cors

package main

import "github.com/gin-gonic/gin"
import "github.com/gin-contrib/cors"

func main() {

    r := gin.Default()

    //cors
	r.Use(cors.New(cors.Config{
        AllowOrigins:  []string{"*"},
        AllowMethods:  []string{"PUT", "PATCH", "GET", "POST", "DELETE"},
        AllowHeaders:  []string{"content-type"},
        ExposeHeaders: []string{"X-Total-Count"},
    }))

    r.GET("/test", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "test": success,
        })
    })

    r.Run() // listen on 0.0.0.0:8080
}

Spring Boot 使用配置类

@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }

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

    @Bean
    public MultipartResolver multipartResolver() {
        return new CommonsMultipartResolver();
    }
}

Vert.x 使用 CorsHandler

//cors
router.route().handler(CorsHandler.create("*").allowedMethod(HttpMethod.POST));
