zeromq的使用（windows）

注：本文说的是windows平台的使用

1.官网下载源码：http://zeromq.org/intro:get-the-software

下载stable release is v4.1.6

 2.vs2013进行编译lib库和dll（只编译libzmq工程即可）

找到路径：zeromq-4.1.6\builds\msvc\vs2013，用vs2013打开libzmq.sln。

直接编译libzmq会报错：

LINK : fatal error LNK1104: cannot open file 'libsodium.lib'

将libsodium设置为不链接：

 编译成功，编译后的文件（以win32 Releasewei）在zeromq-4.1.6\bin\Win32\Release\v120\dynamic下：

3.实战

将lib文件和头文件zmq.h、zmq_utils.h引入工程

（1）发布

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

#include "stdafx.h"
#include
#include"zmq.h"
#include"zmq_utils.h"

int main() {
	void *context = zmq_ctx_new();
	void *publisher = zmq_socket(context, ZMQ_PUB);
	zmq_bind(publisher, "tcp://*:9998");
	char sendbuf[64] = {0};
	int cnt = 0;
	while (cnt < 1000)
	{
		sprintf_s(sendbuf, "msg消息----%d", cnt++);
		std::cout << "msg消息----" << cnt << std::endl;
		zmq_send(publisher, sendbuf, strlen(sendbuf), 0);
		Sleep(1000);
		
	}
	std::cout << "publisher over!" << std::endl;
	zmq_close(publisher);
	zmq_ctx_destroy(context);
	getchar();
	return 0;
}

（2）订阅

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

#include "stdafx.h"
#include
#include"zmq.h"
#include"zmq_utils.h"

int main(void)
{
	void *context = zmq_ctx_new();
	void *subscriber = zmq_socket(context, ZMQ_SUB);

	zmq_setsockopt(subscriber, ZMQ_SUBSCRIBE, "", 0);
	zmq_connect(subscriber, "tcp://127.0.0.1:9998");
	while(1)
	{
		char recvbuf[64] = {0};
		int ret = zmq_recv(subscriber, recvbuf, 64, ZMQ_DONTWAIT);//ZMQ_DONTWAIT表示zmq_recv设置为非阻塞
		if (ret == -1)
		{
			if (errno == EAGAIN) continue;
			else
			{
				std::cout << "接收错误"<< std::endl;
				break;
			}
		}
			std::cout << recvbuf << std::endl;
	}
	zmq_close(subscriber);
	zmq_ctx_destroy(context);
	getchar();
	return 0;
}
