C++ winsock服务器接受函数返回10022错误
C++ winsock服务器接受函数返回10022错误
提问于 2019-06-06 02:09:37
我摆脱了这个错误，现在我似乎被其他东西卡住了。
我在Code：：块上有单独的Winsock客户端和服务器程序。我试图从客户机向服务器发送一条消息，但是服务器程序似乎在accept()函数之前就冻结了，除了“侦听传入的连接”之外什么也没做。输出。客户端缓冲区中的消息永远不会出现在服务器控制台中。
看起来肯定是服务器程序中的accept函数出了问题。这似乎是服务器程序冻结的地方。在那之后，我尝试输入一个随机的cout行，但是没有输出。
在“消息发送”之后，客户端似乎也冻结了。但几分钟后，我看到"recv失败“，然后是”回复已收到“，然后是一行类似于表情符号的文字。我想我有下面链接的图片。
下面是我的客户端代码：
#include <iostream>
#include <winsock2.h>
#include <windows.h>
#include <ws2tcpip.h>
#include <stdio.h>
#pragma comment(lib, "ws2_32.lib")
using namespace std;
int main()
{
WSADATA wsaData;
SOCKET sock;
sockaddr_in server;
char *buffer, server_reply[2000];
int recv_size;
int iResult;
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != 0) {
printf("WSAStartup failed: %d\n", iResult);
} else {
printf("WSAStartup successful!: %d\n", iResult);
}
sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (sock == INVALID_SOCKET){
printf("Socket not created.\n");
} else {
printf("Socket created.\n");
}
server.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
server.sin_family = AF_INET;
server.sin_port = htons(80);
if(connect(sock, (SOCKADDR *)&server, sizeof(server)) != 0){
printf("Connect Error : %d" , WSAGetLastError());
} else {
printf("Connected\n");
};
buffer = "Hello there!";
send(sock, buffer, sizeof(buffer), 0);
printf("Message Sent.\n");
if((recv_size = recv(sock , server_reply , 2000 , 0)) == SOCKET_ERROR)
{
puts("recv failed");
}
puts("Reply received\n");
//Add a NULL terminating character to make it a proper string before printing
server_reply[recv_size] = '\0';
puts(server_reply);
closesocket(sock);
WSACleanup();
return 0;
}下面是我的服务器代码：
#include <iostream>
#include <winsock2.h>
#include <windows.h>
#include <ws2tcpip.h>
#include <stdio.h>
#pragma comment(lib, "ws2_32.lib")
using namespace std;
int main()
{
WSADATA wsaData;
SOCKET server1, client;
sockaddr_in serverAddr, clientAddr;
int iResult;
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != 0) {
printf("WSAStartup failed: %d\n", iResult);
} else {
printf("WSAStartup successful!: %d\n", iResult);
}
server1 = socket(AF_INET, SOCK_STREAM, 0);
if (server1 == INVALID_SOCKET){
printf("Socket not created.\n");
} else {
printf("Socket created.\n");
}
serverAddr.sin_addr.S_un.S_addr = INADDR_ANY;
serverAddr.sin_family = AF_INET;
serverAddr.sin_port = htons(8888);
if(bind(server1, (SOCKADDR *)&serverAddr, sizeof(serverAddr)) == SOCKET_ERROR){
printf("Bind failed. : %d" , WSAGetLastError());
} else {
printf("Bind successful.\n");
}
if(listen(server1, SOMAXCONN) != 0){
printf("Server not listening. : %d" , WSAGetLastError());
} else {
cout << "Listening for incoming connections..." << endl;
}
char buffer[1024];
int clientAddrSize = sizeof(clientAddr);
if((client = accept(server1, (SOCKADDR *)&clientAddr, &clientAddrSize)) == INVALID_SOCKET)
{
printf("Connect Error : %d" , WSAGetLastError());
} else {
cout << "Client connected!" << endl;
recv(client, buffer, sizeof(buffer), 0);
cout << "Client says: " << buffer << endl;
memset(buffer, 0, sizeof(buffer));
closesocket(client);
closesocket(server1);
cout << "Client disconnected." << endl;
}
WSACleanup();
return 0;
}我正在尝试使用CodeBlocks中的C++构建一个Winsock服务器程序，以便与我的客户机程序一起使用。但是，accept函数返回错误代码10022，据我所知，这意味着无效参数。我不认为我在accept函数中的任何参数都是无效的。谢谢你的帮助！

只需从您的代码中删除这一行：
using namespace std;一切都会好起来的。
之所以会出现这个错误，是因为std包具有类似的bind函数，所以当您调用bind时，它会调用std::bind，而不是socket的bind。
