我喜歡能夠做非常簡單的事情，等待客戶端連接到 dlv 調試器，然后再繼續代碼但沒有成功。我有簡單的 go 服務器：package mainimport (    "fmt"    "net/http")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() {    fmt.Println("server started now!")    http.HandleFunc("/hello", hello)    http.HandleFunc("/headers", headers)    http.ListenAndServe(":8090", nil)}我像這樣在 linux 機器上啟動服務器：vagrant@vagrant:~/go_dev/very_simple_server_dir$ dlv debug /home/vagrant/go_dev/very_simple_server_dir/very_simple_server.go --headless --listen=:3000  --logAPI server listening at: [::]:30002022-10-31T06:18:47Z warning layer=rpc Listening for remote connections (connections are not authenticated nor encrypted)2022-10-31T06:18:47Z info layer=debugger launching process with args: [/home/vagrant/go_dev/very_simple_server_dir/__debug_bin]2022-10-31T06:18:47Z warning layer=debugger can't find build-id note on binary在 visual studio 代碼中，launch.json 如下所示："version": "0.2.0",    "configurations": [        {            "name": "Connect to server",            "type": "go",            "request": "attach",            "mode": "remote",            "remotePath": "/home/vagrant/go_dev/very_simple_server_dir/",            "cwd" : "${workspaceFolder}",            "port": 3000,            "host": "127.0.0.1",            "trace": "verbose",            "asRoot": true,        }    ]它可以很好地連接到遠程服務器問題是我喜歡 dlv 調試服務器在執行 go 代碼之前等待客戶端連接。我希望能夠在 func main() 第二行中設置斷點我怎樣才能做到這一點 ？
