Serve a mp3 file with golang through websocket
问题
我想用Golang从WebSocket连接中提供一个文件。我可以像这样发送文件吗：
{type:"file_manage",information:"file.mp3"}？

只需读取文件并通过 WebSocket 发送。
package main
import (
"fmt"
"net/http"
"os"
"golang.org/x/net/websocket"
)
func EchoServer(ws *websocket.Conn) {
file, _ := os.ReadFile("a.txt")
n, err := ws.Write(file)
if err != nil {
fmt.Println(err)
}
fmt.Println(n, "字节已写入")
}
func main() {
http.Handle("/ws", websocket.Handler(EchoServer))
err := http.ListenAndServe(":12345", nil)
if err != nil {
panic("ListenAndServe: " + err.Error())
}
}
英文:
Just read file, and send by websocket.
package main
import (
"fmt"
"net/http"
"os"
"golang.org/x/net/websocket"
)
func EchoServer(ws *websocket.Conn) {
file, _ := os.ReadFile("a.txt")
n, err := ws.Write(file)
if err != nil {
fmt.Println(err)
}
fmt.Println(n, "bytes written")
}
func main() {
http.Handle("/ws", websocket.Handler(EchoServer))
err := http.ListenAndServe(":12345", nil)
if err != nil {
panic("ListenAndServe: " + err.Error())
}
}
