golang的指针到string，string到指针的转换

func (this *Server) socketParserHandler(client *genTcpServer.Client, fullData []byte) {

    fmt.Println("original data is", client)
    strPointerHex := fmt.Sprintf("%p", unsafe.Pointer(client))
    fmt.Println("connection is", strPointerHex)

    strPointerInt := fmt.Sprintf("%d", unsafe.Pointer(client))
    fmt.Println("connection is", strPointerInt)

    i, _ := strconv.ParseInt(strPointerInt, 10, 0)

    var pointer *genTcpServer.Client
    pointer = *(**genTcpServer.Client)(unsafe.Pointer(&i))
    fmt.Println("connection pointer is", pointer)

    debugMsg := fmt.Sprintf("%p", unsafe.Pointer(pointer))
    fmt.Println("debugMsg is", debugMsg)
