Golang开发：跨域配置

跨域中间件

/lib/middleware/crossorigin_mv.go

package middleware

import (
	"github.com/gin-gonic/gin"
	"net/http"
)

/**
 * 跨域设置
 */
func CrossOriginMiddleware() gin.HandlerFunc {
	return func(context *gin.Context) {
		method := context.Request.Method
		context.Header("Access-Control-Allow-Origin", "*")
		context.Header("Access-Control-Allow-Headers", "Content-Type,AccessToken,X-CSRF-Token, Authorization, Token")
		context.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS")
		context.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Content-Type")
		context.Header("Access-Control-Allow-Credentials", "true")
		if method == "OPTIONS" {
			context.AbortWithStatus(http.StatusNoContent)
		}
		context.Next()
	}
}

使用中间件

ginServ := gin.Default()
ginServ.Use(middleware.CrossOriginMiddleware())
