英文:
Updating go websocket library to latest version
问题
我正在Ubuntu上运行Go编译器，使用sudo apt-get install golang进行安装。
我已经成功编译并执行了一个“微不足道的示例服务器”代码（请参阅http://golang.org/pkg/websocket/#Handler）
package main
import (
"http"
"io"
"websocket"
)
// Echo the data received on the Web Socket.
func EchoServer(ws *websocket.Conn) {
io.Copy(ws, ws);
}
func main() {
http.Handle("/echo", websocket.Handler(EchoServer));
err := http.ListenAndServe(":12345", nil);
if err != nil {
panic("ListenAndServe: " + err.String())
}
}
然而，我无法使用我的版本的Chromium（16.0.912.77）连接到服务器。我假设Chrome已经实现了RFC 6455 Websocket（版本13），但是Ubuntu的_golang_软件包中的go websocket库已经过时了。
所以，我的问题是：如何仅更新websocket包到最新版本？
英文:
I am running the Go compiler on Ubuntu, installed using sudo apt-get install golang
I've successfully compiled and executed the code for a Trivial example server (See http://golang.org/pkg/websocket/#Handler )
package main
import (
"http"
"io"
"websocket"
)
// Echo the data received on the Web Socket.
func EchoServer(ws *websocket.Conn) {
io.Copy(ws, ws);
}
func main() {
http.Handle("/echo", websocket.Handler(EchoServer));
err := http.ListenAndServe(":12345", nil);
if err != nil {
panic("ListenAndServe: " + err.String())
}
}
However, I fail to connect to the server with my version of Chromium (16.0.912.77). I assume Chrome has implemented the RFC 6455 Websocket (version 13), but that the go websocket library in the Ubuntu golang package is out of date.
So, my question is: How can I update only the websocket package to the latest version?

Go websocket包的最新版本是net/websocket，位于code.google.com/p/go.net/websocket，需要Go 1周开发版本。
对于Ubuntu golang-weekly：Ubuntu PPA Go软件包。
对于周开发版本的文档：Go编程语言。
英文:
The latest version of the Go websocket package is net/websocket at code.google.com/p/go.net/websocket, which requires the Go 1 weekly development release.
For Ubuntu golang-weekly: Ubuntu PPA packages for Go.
For weekly development release documentation: Go Programming Language.

我猜Ubuntu软件包仓库中的Go版本可能是r60.3（或者类似的版本），现在有点过时了。使用最新的每周版本，将代码更改为：
package main
import (
"code.google.com/p/go.net/websocket"
"io"
"net/http"
)
// Echo the data received on the Web Socket.
func EchoServer(ws *websocket.Conn) {
io.Copy(ws, ws)
}
func main() {
http.Handle("/echo", websocket.Handler(EchoServer))
err := http.ListenAndServe(":12345", nil)
if err != nil {
panic("ListenAndServe: " + err.Error())
}
}
此外，在websocket包中将s/ParseRequestURI/ParseRequest/，然后它似乎在这里工作。（1）
更新：对不起，我写/读得太快了，它似乎不起作用，页面显示：“不是websocket协议”（这里是Chrome 18.0.1025.33 beta在64位Ubuntu 10.04上）
更新2012-08-22：上述（1）关于编辑websocket包的注释不再适用。websocket包已经更新，上面的示例（main）代码现在可以编译而无需任何问题。无论如何，我没有测试它是否按照预期工作，对不起。
英文:
I guess the version of Go in Ubuntu package repository is probably r60.3 (or so), which is a bit old now. Use latest weekly, change the code to:
package main
import (
"code.google.com/p/go.net/websocket"
"io"
"net/http"
)
// Echo the data received on the Web Socket.
func EchoServer(ws *websocket.Conn) {
io.Copy(ws, ws)
}
func main() {
http.Handle("/echo", websocket.Handler(EchoServer))
err := http.ListenAndServe(":12345", nil)
if err != nil {
panic("ListenAndServe: " + err.Error())
}
}
Moreover in the websocket package s/ParseRequestURI/ParseRequest/, then it seems to work here.(1)
Update: Sorry, I wrote/read too fast, it doesn't seem to work, the page shows: "not websocket protocol" (here is Chrome 18.0.1025.33 beta on 64b Ubuntu 10.04)
Update 2012-08-22: The above (1) note about editing the websocket package doesn't hold anymore. The websocket package has been meanwhile updated and the example (main) code above now compiles w/o problems. Anyway, I haven't tested if it afterwards does what is should or not, sorry.
