vs2010下libevent的使用

下载最新的libevent，目前是

libevent-2.0.20-stable.tar.gz

修改“D:\libevent-2.0.10-stable\event_iocp.c”、“D:\libevent-2.0.10-stable \evthread_win32.c”、“D:\libevent-2.0.10-stable\listener.c”三个文件，在文件开头分别加上一 行：

#define _WIN32_WINNT 0x0500

在Makefile.nmake中的CFLAGS中加入/ZI选项,同时去掉/Ox优化选项，这样生成的lib库会带有调试信息 

进入VS2010命令提示

切换到libevent的所在目录

nmake /f Makefile.nmake

编译成功生成

libevent.lib、libevent_core.lib、libevent_extras.lib

复制include 和libs

mkdir D:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\include\* D:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\WIN32-Code\* D:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\*.h D:\libevent\include\
mkdir d:\libevent\libs
copy D:\libevent-2.0.16-stable\*.lib D:\libevent\libs\

 新建vs2010控制台项目并使用以下代码

#include <stdio.h>



#define WIN32_LEAN_AND_MEAN

#include <windows.h>

#include <winsock2.h>



#include <event.h>

#include <evhttp.h>



void root_handler(struct evhttp_request *req, void *arg)

{

    struct evbuffer *buf = evbuffer_new();

    if(!buf){

        puts("failed to create response buffer");

        return;

    }



    evbuffer_add_printf(buf, "Hello: %s\n", evhttp_request_uri(req));

    evhttp_send_reply(req, HTTP_OK, "OK", buf);

}



void generic_handler(struct evhttp_request *req, void *arg)

{

    struct evbuffer *buf = evbuffer_new();

    if(!buf){

        puts("failed to create response buffer");

        return;

    }



    evbuffer_add_printf(buf, "Requested: %s\n", evhttp_request_uri(req));

    evhttp_send_reply(req, HTTP_OK, "OK", buf);

}



int main(int argc, wchar_t* argv[])

{

 struct evhttp *httpd;



 WSADATA wsaData;

 DWORD Ret;

 if ((Ret = WSAStartup(MAKEWORD(2, 2), &wsaData)) != 0) {

  printf("WSAStartup failed with error %d\n", Ret);

  return -1;

 }



    event_init();



    httpd = evhttp_start("0.0.0.0", 18505);

    if(!httpd){

  return 1;

 }



    evhttp_set_cb(httpd, "/", root_handler, NULL);

    evhttp_set_gencb(httpd, generic_handler, NULL);



 printf("httpd server start OK!\n");



    event_dispatch();



    evhttp_free(httpd);



 WSACleanup();

    return 0;

}
