C++ WinSock2误差

Question

昨天，我尝试在C++中创建一个套接字服务器，但是编译时会出现错误。错误：

错误6错误LNK2019:函数"public:静态无符号长__cdecl Env：：GetSocket(__cdecl)“中引用的未解析外部符号_imp_socket@12 (?GetSocket@Env@@SAKXZ) C:\Users\JoshuaTha\Documents\Visual 2010\Projects\HabboV5\HabboV5\Network.obj HabboV5

错误5错误LNK2019:函数"public: void __thiscall Network：：Start(__thiscall)“中引用的未解析外部符号_imp_listen@8 (?Start@Network@@QAEXXZ) C:\Users\JoshuaTha\Documents\Visual 2010\Projects\HabboV5\HabboV5\Network.obj HabboV5

错误3错误LNK2019:函数"public: void __thiscall Network：：Start(__thiscall)“中引用的未解析外部符号_imp_bind@12 (?Start@Network@@QAEXXZ) C:\Users\JoshuaTha\Documents\Visual 2010\Projects\HabboV5\HabboV5\Network.obj HabboV5

错误2错误LNK2001:未解决的外部符号"public:静态类网络* Env:: Network“(网络@Env@@2PAV0@A)C：\User\JoshuaTha\Documents\Visual 2010\Projects\ HabboV5 5\HabboV5 5\HabboV5.obj HabboV5

错误7错误LNK1120: 5个未解决的外部文件C：\User\JoshuaTha\Documents\Visual 2010\Projects\ HabboV5 5\Debug\HabboV5.exe HabboV5

我的主要.cpp课程：

// HabboV5.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include "Env.h"

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
cout.write("hi", 2);
cout << "Hello World!" << endl;

Env::Network = new Network();
Env::Network->Start();

while (1)
{
    char input[256];
    cin.getline(input, 256);
}
}

网络.h：

#pragma once
#include <WinSock2.h>

class Network
{
private:
    SOCKET socket;
public:
    Network(void);
    void Start();
};

Network.cpp：

#include "StdAfx.h"
#include "Network.h"
#include <WinSock2.h>
#include "Env.h"

Network::Network(void)
{
}

void Network::Start()
{
    this->socket = Env::GetSocket();

    SOCKADDR_IN sInformation;

    sInformation.sin_family = AF_INET;
    sInformation.sin_addr.s_addr = INADDR_ANY;
    sInformation.sin_port = htons(30000);

    bind(this->socket, (SOCKADDR*) (&sInformation), sizeof(sInformation));
    listen(this->socket, 10);
}

环境h：

#include "stdafx.h"
#include "Network.h"
#include <WinSock2.h>

class Env
{
public:
    static Network* Network;

    static DWORD GetSocket()
    {
        return socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    }
};

在链接器选项(在项目右击、链接器、输入)中，您需要将wsock32.lib或ws2_32.lib添加到输入文件列表中。
