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");}}
