英文:
Where does Go web server look for the files
问题
我有一个简单的网页应用程序，代码文件名为HttpServer.go：
package main
import (
"net/http"
)
func main() {
mux := http.NewServeMux()
files := http.FileServer(http.Dir("/public"))
mux.Handle("/static/", http.StripPrefix("/static/", files))
server := &http.Server{
Addr: "localhost:8080",
Handler: mux,
}
server.ListenAndServe()
}
我将这个代码文件放在%GOPATH%/src/first_app目录下，并使用go install命令安装了这个程序，first_app.exe出现在%GOPATH%/bin目录中。
当我启动web服务器后，我访问了http://localhost:8080/static/a.txt，但是出现了404（未找到）的错误，提示找不到a.txt文件。
我想问一下，我应该把public目录和a.txt文件放在哪里？
英文:
I have a simple web application, the code file which is named HttpServer.go is:
package main
import (
"net/http"
)
func main() {
mux := http.NewServeMux()
files := http.FileServer(http.Dir("/public"))
mux.Handle("/static/", http.StripPrefix("/static/", files))
server := &http.Server{
Addr: "localhost:8080",
Handler: mux,
}
server.ListenAndServe()
}
I have put the this code file under %GOPATH%/src/first_app, and I go install this program, the first_app.exe shows up in %GOPATH%/bin
When I startup the webserver,I accessed
http://localhost:8080/static/a.txt, but 404(NOT FOUND) complains that a.txt is not found.,
I would ask where should I put the directory public and a.txt

根据你在http.Dir表达式中指定的路径查找。在你的情况下是/public。
很可能你的系统上没有名为/public的路径（因为这是我熟悉的所有操作系统中的非标准目录路径，我猜你还没有创建它）。
将/public更改为与你放置文件的路径匹配。
英文:
It looks in the path you specify in your http.Dir expression. /public in your case.
Most likely you don't have a path called /public on your system (since this is a non-standard directory path on all OSes I'm familiar with, and I suspect you haven't created it).
Change /public to match the path where you put your files.
