下载安装 go-sciter 包

go get github.com/sciter-sdk/go-sciter

修改 sciter-x-api.c ，添加如下代码：

HSARCHIVE SCAPI SciterOpenArchive (LPCBYTE archiveData, UINT archiveDataLength) { return SAPI(NULL)->SciterOpenArchive (archiveData,archiveDataLength); }


 BOOL SCAPI SciterGetArchiveItem (HSARCHIVE harc, LPCWSTR path, LPCBYTE* pdata, UINT* pdataLength){return SAPI(NULL)->SciterGetArchiveItem (harc,path,pdata,pdataLength); }

修改 sciter.go，添加如下代码：

func (s *Sciter) OpenArchive(data []byte) {
    s.har = C.SciterOpenArchive((*C.BYTE)(&data[0]), C.UINT(len(data)))
}
func (s *Sciter) GetArchiveItem(uri string) []byte {
    var pv uintptr = 0
    var length uint = 0
    pBytes := (*C.LPCBYTE)(unsafe.Pointer(&pv))
    pnBytes := (*C.UINT)(unsafe.Pointer(&length))
    r := C.SciterGetArchiveItem(s.har, StringToWcharPtr(uri), pBytes, pnBytes)
    if r == 0 {
        return nil
    }
    ret := []byte{}
    for i := 0; i < int(length); i++ {
        b := *(*byte)(unsafe.Pointer(pv + uintptr(i)))
        ret = append(ret, b)
    }
    return ret
}

打包资源：

packfolder.exe res resources.cpp -v "res"

//packfolder.exe “资源文件夹”,“输出cpp文件名” -v "变量名"

拷贝cpp内容存为res.go：

// res.go
package main


var res = []byte{
...

编写main.go

package main


import (
    "log"
    "strings"
    "github.com/oskca/sciter"
    "github.com/oskca/sciter/window"
)





func OnLoadData(s *sciter.Sciter) func(ld *sciter.ScnLoadData) int {
    return func(ld *sciter.ScnLoadData) int {
        uri := ld.Uri()
        log.Println("loading:", uri)
        if strings.HasPrefix(uri, "this://app/") {
            path := uri[11:]
            log.Println("path:", path)
            data := s.GetArchiveItem(path)
            if data == nil {
                log.Println("GetArchiveItem:False")
                return sciter.LOAD_OK
            }
            s.DataReady(uri, data)
        }
        return sciter.LOAD_OK
    }
}





func newHandler(s *sciter.Sciter) *sciter.CallbackHandler {
    return &sciter.CallbackHandler{
        OnLoadData: OnLoadData(s),
    }
}





func main() {
    w, err := window.New(sciter.SW_TITLEBAR|sciter.SW_RESIZEABLE|sciter.SW_CONTROLS|sciter.SW_MAIN, sciter.NewRect(300, 300, 600, 400))
    if err != nil {
        log.Fatal("Create Window Error: ", err)
    }
    w.SetCallback(newHandler(w.Sciter))
    w.OpenArchive(res)
    w.LoadFile("app/main.htm")
    w.Show()
    w.Run()


}
