我尝试从客户机通过行foreach循环发送字符串服务器产品线:如何通过QTcpSocket发送和读取字符串行?
foreach(QString s, stringlist)
client.sendMessage(s);
但客户只收到第一个字符串。当我从字符串中删除“\ n”时,服务器接收到一串合并成一个大字符串的字符串。我认为添加“\ n”会将数据分成字符串,我可以用readLine()
来阅读。我错过了什么?
我的客户
class cClient:public QTcpSocket
{
public:
void sendMessage(QString text)
{
text = text + "\n";
write(text.toUtf8());
}
};
和服务器:
class pServer:public QTcpServer
{
Q_OBJECT
public:
pServer()
{
connect(this,SIGNAL(newConnection()),SLOT(slotNewConnection()));
}
public slots:
void slotNewConnection()
{
QTcpSocket* c = nextPendingConnection();
connect(c,SIGNAL(readyRead()),this, SLOT(readData()));
}
void readData()
{
QTcpSocket* conn = qobject_cast<QTcpSocket*>(sender());
QString data = QString(conn->readLine());
}
};
谢谢!这正是我错过的。现在一切正常! – lena
