英文:
Making a Simple FileServer with Go and Localhost Refused to Connect
问题
现在我有从一本书中提取的以下代码。
package main
import (
"net/http"
)
func main() {
h := http.FileServer(http.Dir("."))
http.ListenAndServeTLS(":8001", "rui.crt", "rui.key", h)
}
我期望它可以列出main.go文件夹中的所有文件，但是当我浏览到 https://localhost:8001 时，我只能看到：
This site can’t be reached.
localhost refused to connect.
我使用LiteIDE构建和运行程序。点击BuildAndRun后，显示以下消息。
F:/Go/bin/go.exe build -i [E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server]
Success: process exited with code 0.
E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server/server.exe [E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server]
Success: process exited with code 0.
为什么会这样，我该如何修复它？
英文:
Now I have the following code extracted from a book.
package main
import (
"net/http"
)
func main() {
h := http.FileServer(http.Dir("."))
http.ListenAndServeTLS(":8001", "rui.crt", "rui.key", h)
}
I expect it can list all the file in the folder of main.go but when I browse to:
https://localhost:8001
I can only see:
This site can’t be reached.
localhost refused to connect.
I use LiteIDE to build and run the program. After <kbd>BuildAndRun</kbd> clicked, the following messages are shown.
F:/Go/bin/go.exe build -i [E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server]
Success: process exited with code 0.
E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server/server.exe [E:/Users/User/Desktop/codespace_v2.6.6/dev/server_side/golang/go_codespace_v2.1/server]
Success: process exited with code 0.
Why and how can I fix it?

你的系统找不到证书文件。这个错误意味着你需要在主二进制文件旁边有一个名为"rui.crt"的文件。如果你没有证书，请参考：https://stackoverflow.com/questions/10175812/how-to-create-a-self-signed-certificate-with-openssl
然后将"server.pem"和"server.key"文件复制到你的二进制(.exe)文件目录中，并运行以下示例代码进行测试：
package main
import (
"fmt"
"log"
"net/http"
)
type server struct {
}
func (s server) ServeHTTP(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "*Hello World\n*")
}
func main() {
if err := http.ListenAndServeTLS(":443", "server.pem", "server.key", server{}); err != nil {
log.Fatal(err)
}
}
然后打开网页：https://127.0.0.1/，如果防火墙弹出提示，请选择允许，如果看到"There is a problem with this website’s security certificate."，请点击继续（高级）。
输出结果为：
*Hello World
*
英文:
your system cannot find the certificate file.:
this error means you need "rui.crt" file alongside with your main binary file.
if you do not have certificate see: https://stackoverflow.com/questions/10175812/how-to-create-a-self-signed-certificate-with-openssl
then copy "server.pem", "server.key" files to your binary(.exe) file directory
and run this sample code (for test):
package main
import (
"fmt"
"log"
"net/http"
)
type server struct {
}
func (s server) ServeHTTP(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "*Hello World\n*")
}
func main() {
if err := http.ListenAndServeTLS(":443", "server.pem", "server.key", server{}); err != nil {
log.Fatal(err)
}
}
then open web page: https://127.0.0.1/
if firewall poped up say yes,
if you see There is a problem with this website’s security certificate. say continue (advance).
output:
*Hello World
*
