英文:
Golang write net.Dial response to the browser
问题
我正在使用net包进行编程，并且想要创建一个简单的代理。首先，在本地创建一个监听器，然后拨号远程地址。
remote, err := net.Dial("tcp", "google.com:80")
if err != nil {
log.Fatal(err)
}
defer remote.Close()
fmt.Fprint(remote, "GET / HTTP/1.0\r\n\r\n")
你想要如何将响应传输到浏览器？或者我需要使用默认的Web服务器并复制响应主体吗？我真的想尝试使用net包或其他方法。
谢谢。

I am playing with the net package, and i want to make a simple proxy.
First i make a listener on localhost, then i dial the remote address
remote, err := net.Dial("tcp", "google.com:80")
if err != nil {
log.Fatal(err)
}
defer remote.Close()
fmt.Fprint(remote, "GET / HTTP/1.0\r\n\r\n")
How can i pipe the response to the browser? Or do i need to work with the default webserver and copy the response body? I really want to try it with net package or something
thx

将远程连接复制使用2个goroutine和io.Copy函数。
func copyContent(from, to net.Conn, done chan bool) {
_, err := io.Copy(from, to)
if err != nil {
done <- true
}
done <- true
}
// 在主函数中
done := make(chan bool, 2)
go copyContent(conn, remote, done)
go copyContent(remote, conn, done)
<-done
<-done
以上是要翻译的内容。
英文:
To copy the connection from the remote is used 2 goroutines with io.Copy
func copyContent(from, to net.Conn, done chan bool) {
_, err := io.Copy(from, to)
if err != nil {
done <- true
}
done <- true
}
// in the main func
done := make(chan bool, 2)
go copyContent(conn, remote, done)
go copyContent(remote, conn, done)
<-done
<-done
