嘗試從共享庫運行 servr，所以我做了以下操作：將shahred圖書館寫成：// server.gopackage mainimport ( "fmt" "net/http")import "C"func hello(w http.ResponseWriter, req *http.Request) { fmt.Fprintf(w, "hello\n")}func headers(w http.ResponseWriter, req *http.Request) { for name, headers := range req.Header { for _, h := range headers { fmt.Fprintf(w, "%v: %v\n", name, h) } }}func main() {}// export Run serverfunc Run(port string) { http.HandleFunc("/hello", hello) http.HandleFunc("/headers", headers) if err := http.ListenAndServe("localhost:"+port, nil); err == nil { fmt.Println("listening to 8090") } else { fmt.Println("ListenAndServe: ", err) }}將共享庫編譯為：$ go build -buildmode c-shared -o server.so server.go將調用共享庫中的函數的主文件寫入為：Run//main.gopackage main/*#cgo LDFLAGS: -ldl#include <dlfcn.h>void Run(char* port){}*/import "C"func main() { // handle := C.dlopen(C.CString("server.so"), C.RTLD_LAZY) // C.dlsym(handle, C.CString("8090")) C.dlopen(C.CString("server.so"), C.RTLD_LAZY) C.run(C.CString("8090"))}將主文件運行為：$ go run main.go主功能已直接終止，并且 srver 尚未在http://localhost:8090/hello

你為什么不把它分成一個go包（例如：包服務器）和導入這個包的主應用程序：
yourproject/cmd/server/main.go
package main
import (
"yourproject/internal/server"
)
func main() {
srv := server.New()
// ...
port := "8443"
// do some logic here
srv.Run(port)
}
和 yourproject/internal/server/server.go
package server
import (
"fmt"
"net/http"
)
import "C"
type Server struct{}
func New() *Server {
return &Server{}
}
func hello(w http.ResponseWriter, req *http.Request) {
fmt.Fprintf(w, "hello\n")
}
func headers(w http.ResponseWriter, req *http.Request) {
for name, headers := range req.Header {
for _, h := range headers {
fmt.Fprintf(w, "%v: %v\n", name, h)
}
}
}
// export Run server
func (s *Server) Run(port string) {
http.HandleFunc("/hello", hello)
http.HandleFunc("/headers", headers)
if err := http.ListenAndServe("localhost:"+port, nil); err == nil {
fmt.Println("listening to 8090")
} else {
fmt.Println("ListenAndServe: ", err)
}
}
