我正在尝试在每个响应上设置服务器标头。我正在尝试使用Gin的中间件来实现这一点。但是,由于某种原因,这不会设置标题。到目前为止,我已经尝试对此进行调试,但我不明白为什么这不起作用。可能我在这里遗漏了一些东西。这是代码package mainimport "fmt"import "github.com/gin-gonic/gin"const SERVER_INFO = "Some-Play-Server"type ServerHeader struct { gin.ResponseWriter ServerInfo string}func (w *ServerHeader) Write(data []byte) (int, error) { if w.Header().Get("Server") == "" { w.Header().Add("Server", w.ServerInfo) } return w.ResponseWriter.Write(data)}func InitServerHeader() gin.HandlerFunc { return func(c *gin.Context) { writer := &ServerHeader{c.Writer, SERVER_INFO} c.Writer = writer c.Next() }}func main() { mux := gin.Default() mux.Use(InitServerHeader()) mux.GET("/", func(c *gin.Context) { c.String(200, "OK") }) fmt.Println("Server Listening on 0.0.0.0:8080") mux.Run(":8080")}而且,这是测试输出❯ curl -v http://localhost:8080/* About to connect() to localhost port 8080 (#0)* Connected to localhost (::1) port 8080 (#0)> GET / HTTP/1.1> User-Agent: curl/7.30.0> Host: localhost:8080> Accept: */*> < HTTP/1.1 200 OK< Content-Type: text/plain< Date: Wed, 13 Aug 2014 16:54:21 GMT< Content-Length: 2< OK
