Go gin framework CORS

Question

I\'m using Go gin framework gin

func CORSMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {
        c.Writer.Header().Set(\"Content-Type\", \"a         


        

Answer 1

This worked for me - NOTE: the setting of header directly.

func CORSMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {

        c.Header("Access-Control-Allow-Origin", "*")
        c.Header("Access-Control-Allow-Headers", "*")
        /*
            c.Writer.Header().Set("Access-Control-Allow-Origin", "*")
            c.Writer.Header().Set("Access-Control-Allow-Credentials", "true")
            c.Writer.Header().Set("Access-Control-Allow-Headers", "access-control-allow-origin, access-control-allow-headers")
            c.Writer.Header().Set("Access-Control-Allow-Methods", "GET, HEAD, POST, PUT, DELETE, OPTIONS, PATCH")
        */

        if c.Request.Method == "OPTIONS" {
            c.AbortWithStatus(204)
            return
        }

        c.Next()
    }
}
