QT windows与linux之间sokcet通信中文乱码问题解决方法

linux发送与接收都转码utf-8:

tcpClient ->write( send_msg.toUtf8());//解决乱码，发送转码

 

 

接收：

QByteArray buffer = tcpClient->readAll();
if(!buffer.isEmpty())
{
// ui->plainTextEdit_Recv_Msg->appendPlainText(str_time+" "+QString::fromLocal8Bit(buffer));
ui->plainTextEdit_Recv_Msg->appendPlainText(str_time+" "+QString::fromUtf8(buffer)); //linux 读取数据，接收转码

}

windows发送与接收都转码utf-8:

 

linux接收：

void Dialog_debug::slot_readData()
{
    QDateTime current_time=QDateTime::currentDateTime();
   // QString str_time=current_time.toString("yyyy-MM-dd hh:mm:ss.zzz ddd");//ddd--周五，zzz毫秒
    QString str_time=current_time.toString("yyyy-MM-dd hh:mm:ss");//ddd--周五，zzz毫秒
    QByteArray buffer = tcpClient->readAll();
    if(!buffer.isEmpty())
    {
       // ui->plainTextEdit_Recv_Msg->appendPlainText(str_time+" "+QString::fromLocal8Bit(buffer));
        ui->plainTextEdit_Recv_Msg->appendPlainText(str_time+" "+QString::fromUtf8(buffer)); //linux 读取数据

    }
}

 

windows发送：

void Server::on_pushButton_Send_clicked()
{
    if(ui->listWidget_IP->selectedItems().length()>0)
    {
        foreach(QListWidgetItem* item, ui->listWidget_IP->selectedItems())
        {
            QString clientIP=item->text().split(":")[0];
            int clientPort=item->text().split(":")[1].toInt();
            for(int i=0;i<tcpClients.length();i++)
            {
                if(tcpClients[i]->peerAddress().toString()==clientIP &&tcpClients[i]->peerPort()==clientPort)
                {
                    tcpClients[i]->write(ui->plainTextEdit_Send_Msg->toPlainText().toUtf8());//windows与linux之间数据传送
                   //  tcpClients[i]->write(ui->plainTextEdit_Send_Msg->toPlainText().toLocal8Bit());////fromLocal8Bit显示中文，解决乱码,windows之间
                     ui->plainTextEdit_Recv_Msg->appendPlainText(GetCurrentTimeStr()+" 发送："+ui->plainTextEdit_Send_Msg->toPlainText());
                }
            }

        }
    }
    else
    {
        QMessageBox::information(this,"提示","IP列表未选择");
    }



}
