跨域中间件
一般跨域不推荐写在程序里。应该配置在nginx里或网关里
如果你非要写 应该配置一个Gin 原始中间件
func cros() gin.HandlerFunc {
return func(c *gin.Context) {
method := c.Request.Method
if method != "" {
c.Header("Access-Control-Allow-Origin", "*") // 可将将 * 替换为指定的域名
c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, UPDATE")
c.Header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization,X-Token")
c.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Cache-Control, Content-Language, Content-Type")
c.Header("Access-Control-Allow-Credentials", "true")
}
if method == "OPTIONS" {
c.AbortWithStatus(http.StatusNoContent)
}
}
}
func main() {
//Ignite方法 支持 配置原始Gin 中间件,全局的
goft.Ignite(cros()).
Config(Configuration.NewMyConfig()).
Attach(fairing.NewGlobalFairing()).
Mount("", classes.NewIndexClass()). //控制器,挂载到v1
Launch()
}
OPTOINS这块 是不会执行的。就是个语法标记
