Socket编程+Google Protocol搭建简单的客户端服务器方式1

来源：互联网发布：mac os x 原版dmg 编辑：程序博客网时间：2024/06/07 20:11

一种比较搓的方式利用Google Protoco来进行客户端服务器数据通信

A客户端模块：

1.新建一个win32控制台应用程序,是空项目,名字为MyCient

2. Google Protocol环境配置(详细配置看我文章http://blog.csdn.net/dugaoda/article/details/50342449)

2.1.

2.2.添加lib文件到项目Debug下面

3.生成协议person. proto

内容为

package tutorial;

message Person {

required string name = 1;

required int32 age = 2;

optional string email = 3;

}

message msg

{

required int32 id = 1; // message ID

required int32 len = 2; //message Length

required bytes info = 3; //message content = 二进制方式.

}

得到person.pb.h和person.pb.cc

4.新建文件MyClient.cpp

同时添加文件person.pb.h和person.pb.cc

项目文件结构如下

5.编写MyClient.cpp文件内容

先直接贴上代码

// MyClient.cpp : 定义控制台应用程序的入口点。

#include "winsock2.h"

#include <iostream>

#include <fstream>

#include "person.pb.h"

#include "TCPPakDef.hpp"

#pragma comment(lib, "ws2_32.lib")

using namespace std;

using namespace tutorial;

BOOL RecvLine(SOCKET s, char *buf);

int main()

{

tutorial::Person PERSON;

const int BUF_SIZE = 1024;

WSADATA wsd;

SOCKET sHost;

SOCKADDR_IN servAddr;

char buf[BUF_SIZE]="";//接收数据缓冲区

char bufRecv[BUF_SIZE]="";

//截断后面的乱码输出

cout << endl << "1从服务器接受数据:" << buf;

cout << endl << "2从服务器接受数据:" << bufRecv;

int retVal;

//初始化套结字动态库

if (WSAStartup(MAKEWORD(2, 2), &wsd) != 0)

{

cout << "WSAStartup failded!" << endl;

return 1;

}

//创建套接字

sHost = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

if (INVALID_SOCKET == sHost)

{

WSACleanup();//释放套接字资源

return -1;

}

//设置服务器地址

servAddr.sin_family = AF_INET;

servAddr.sin_addr.s_addr = inet_addr("127.0.0.1");

servAddr.sin_port = htons((short)123);

int nServAddlen = sizeof(servAddr);

//连接服务器

retVal = connect(sHost, (LPSOCKADDR)&servAddr, sizeof(servAddr));

if (SOCKET_ERROR == retVal)

{

cout << "connect failed" <<endl;

closesocket(sHost);

WSACleanup();

return -1;

}

while (true)

{

//向服务器发送数据

ZeroMemory(buf, BUF_SIZE);

cout << "向服务器发送数据:";

char buf123[BUF_SIZE]="";

cin >> buf123;

//使用google protobuf 将数据发送出去

//其实在每个MSG的头上面加上ID 在服务器上面解析出来就可以用了

PERSON.set_name("dugoada");

PERSON.set_age(123);

string data;

PERSON.SerializeToString(&data);

char dst[BUF_SIZE];

strcpy(dst, data.c_str());

retVal = send(sHost, dst, sizeof(dst), 0);

if (SOCKET_ERROR == retVal)

{

cout << "send failed!" << endl;

closesocket(sHost);//关闭套接字

WSACleanup();

return -1;

}

// 接收服务器端的数据

ZeroMemory(buf, BUF_SIZE);

recv(sHost, bufRecv, BUF_SIZE, 0);

cout << endl << "从服务器接受数据:" << bufRecv;

}

closesocket(sHost);//关闭套接字

WSACleanup();

return 0;

}

6.关键代码说明

//使用google protobuf 将数据发送出去

//其实在每个MSG的头上面加上ID 在服务器上面解析出来就可以用了

PERSON.set_name("dugoada");

PERSON.set_age(123);

//将PERSON的数据内容序列化到data中

string data;

PERSON.SerializeToString(&data);

//将data数据copy到dst中发送的时候需要用到的是char类型的字符

char dst[BUF_SIZE];

strcpy(dst, data.c_str());

B 服务器模块：

环境配置部分跟客户端一样，代码不一样（注意）

1.编写MyServer.cpp文件内容

先直接贴上代码

// MyServer.cpp : 定义控制台应用程序的入口点。

//#include "stdafx.h"

#include "winsock2.h"

#pragma comment(lib, "ws2_32.lib")

#include <iostream>

using namespace std;

#include <iostream>

#include<fstream>

#include "TCPPakDef.hpp"

#include "person.pb.h"

using namespace tutorial;

int main()

{

tutorial::Person PERSON;

const int BUF_SIZE = 1024;

WSADATA wsd;

SOCKET sServer;

SOCKET sClient;

SOCKADDR_IN addrServ;

char buf[BUF_SIZE];

char sendBuf[BUF_SIZE];

int retVal;

//初始化套结字动态库

if (WSAStartup(MAKEWORD(2, 2), &wsd) != 0)

{

cout << "WSAStartup failded!" << endl;

return 1;

}

//创建套接字

sServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

if (INVALID_SOCKET == sServer)

{

cout << "socket failed!" << endl;

WSACleanup();

return -1;

}

//服务器套接字地址信息设置

addrServ.sin_family = AF_INET;

addrServ.sin_port = htons(123);

addrServ.sin_addr.s_addr = INADDR_ANY;

//绑定

retVal = bind(sServer, (LPSOCKADDR)&addrServ, sizeof(SOCKADDR_IN));

if (SOCKET_ERROR == retVal)

{

cout << "bind failed!" << endl;

closesocket(sServer);

WSACleanup();

return -1;

}

//开始监听

retVal = listen(sServer, 1);

if (SOCKET_ERROR == retVal)

{

cout << "listen failed!" << endl;

closesocket(sServer);

WSACleanup();

return -1;

}

//接受客户端请求

sockaddr_in addrClient;

int addrClientlen = sizeof(addrClient);

sClient = accept(sServer, (sockaddr FAR *)&addrClient, &addrClientlen);

if (INVALID_SOCKET == sClient)

{

cout << "accept failed!" << endl;

closesocket(sServer);

WSACleanup();

return -1;

}

//数据处理

while (true)

{

//接受客户端数据

ZeroMemory(buf, BUF_SIZE);

retVal = recv(sClient, buf, BUF_SIZE, 0);

//方法1 解析google protobuf

string data = buf;

PERSON.ParseFromString(data);

cout << "Name: " << PERSON.name() << endl;

cout << "Age: " << PERSON.age() << endl;

if (SOCKET_ERROR == retVal)

{

cout << "recv, failed!" << endl;

closesocket(sClient);

closesocket(sServer);

WSACleanup();

return -1;

}

if (buf[0] == '0')

break;

cout << "客户端发送的数据:" << buf << endl;

cout << "向客户端发送数据:";

cin >> sendBuf;

send(sClient, sendBuf, strlen(sendBuf), 0);

}

closesocket(sClient);

closesocket(sServer);

WSACleanup();

return 0;

}

6.关键代码说明

//方法1 解析google protobuf

//将数据从data解析到PERSON中

string data = buf;

PERSON.ParseFromString(data);

//得到自己想要的数据

cout << "Name: " << PERSON.name() << endl;

cout << "Age: " << PERSON.age() << endl;
