Question

我想在Qt中编写一个简单的客户端服务器程序服务器是多线程的，但是因为我是Qt的新手，我在多线程中遇到问题而且我得到以下错误：没有＆＃39;使我的服务器无效：：传入连接＆＃34;（qintptr）＆＃34;在类＆＃34; myserver＆＃34;中声明的成员函数。能不能请你帮忙，如果有可能说你有更好的解决方案来编写多线程服务器吗？这是我的代码：

＆＃34; myserver.cpp：＆＃34;

#include "myserver.h"
#include "mythread.h"


myserver::myserver(QObject *parent) :

QObject(parent)
{
}

void myserver::startserver()
{

int port = 1234;

if(s_server.listen(QHostAddress::Any, port))
  {
    qDebug() << "Could not start server";
  }
else
  {
    qDebug() << "Listening to port " ;
  }

}

void myserver::incomingConnections(qintptr socketDescriptor)
{
  mythread *thread = new mythread(socketDescriptor,this);

  qDebug() << socketDescriptor << " Connecting...";

  connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));

  thread->start();
  }


 void myserver::acceptConnection()

 {

  c_client = s_server.nextPendingConnection();

  connect(c_client,SIGNAL(readyRead()),this, SLOT(startRead()));

  qDebug() << " Connecting...";


  }

＆＃34; mythread.cpp：＆＃34;

  #include "mythread.h"
  #include "myserver.h"

  mythread::mythread(qintptr ID, QObject *parent) :

  QThread(parent)
 {
 this->socketDescriptor = ID;
 }


void mythread::run()
  {

  qDebug() << " Thread started";

   socket = new QTcpSocket() ;

   if(!socket->setSocketDescriptor(this->socketDescriptor))

   emit error(socket->error());

   return;

connect(socket, SIGNAL(readyRead()), this, SLOT(readyRead()),   Qt::DirectConnection);

connect(socket, SIGNAL(disconnected()), this, SLOT(disconnected()));


    qDebug() << socketDescriptor << " Client connected";

     exec();
   }


void mythread::readyRead()

{
  QByteArray Data = socket->readAll();

  qDebug() << socketDescriptor << " Data in: " << Data;

  socket->write(Data);
}



void mythread::disconnected()
{
  qDebug() << socketDescriptor << " Disconnected";

  socket->deleteLater();

  exit(0);
}

Answer 1

您是否将实施方法拼错为：

incomingConnections

当您在标题中将其声明为：

时

incomingConnection

Answer 2

检查传入连接拼写和大写以及小写字母组合，如果声明incomingComing，那么它应该是incomingConnection或者如果是incomingconnection则是incomingconnection

错误：没有＆＃39;使我的服务器无效::传入连接（qintptr）＆＃39;在课程＆＃39; myserver＆＃39;中声明的成员函数
