gin使用httputil.NewSingleHostReverseProxy
实现proxy服务代理。
代码示例
package main
import (
"net/http"
"net/http/httputil"
"net/url"
"github.com/gin-gonic/gin"
)
func proxy(c *gin.Context) {
remote, err := url.Parse("http://www.iarno.cn")
if err != nil {
panic(err)
}
proxy := httputil.NewSingleHostReverseProxy(remote)
proxy.Director = func(req *http.Request) {
req.Header = c.Request.Header
req.Host = remote.Host
req.URL.Scheme = remote.Scheme
req.URL.Host = remote.Host
req.URL.Path = c.Param("proxyPath")
}
proxy.ServeHTTP(c.Writer, c.Request)
}
func main() {
r := gin.Default()
//Create a catchall route
r.Any("/*proxyPath", proxy)
r.Run(":8080")
}
