VC - vs2017里poco的websocket使用netssl

1. 首先下载openssl库

http://slproweb.com/products/Win32OpenSSL.html

2. Install OpenSSL (we assume you install to d:\OpenSSL32)
3. 编辑buildwin.cmd，添加如下内容：

set OPENSSL_DIR=d:\OpenSSL32
set OPENSSL_INCLUDE=%OPENSSL_DIR%\include
set OPENSSL_LIB=%OPENSSL_DIR%\lib;%OPENSSL_DIR%\lib\VC
set INCLUDE=%INCLUDE%;%OPENSSL_INCLUDE%
set LIB=%LIB%;%OPENSSL_LIB%

然后使用git bash命令

mkdir cmake_build_x86
cd cmake_build_x86
cmake -G "Visual Studio 15 2017" ..

 

打开工程，看到netssl模块，开始编译即可

 

其他工程使用的时候，在工程里添加

d:\OpenSSL32\include

d:\OpenSSL32\lib\VC

 

代码例子

Poco websocket库特点:

1,使用http/https ClientSession创建websocket client

2,是同步的,这对C++桌面编程来说应该是够用的.

3,依赖openssl.

代码如下:

#include "stdafx.h"

#include 

#include 

#include "Poco/Net/WebSocket.h"

#include "Poco/Net/HTTPClientSession.h"

#include "Poco/Net/HTTPRequest.h"

#include "Poco/Net/ServerSocket.h"

#include "Poco/Net/NetException.h"

#include "Poco/Exception.h"

#include "Poco/Net/HTTPSClientSession.h"

#include "Poco/URIStreamOpener.h"

#include "Poco/StreamCopier.h"

#include "Poco/Path.h"

#include "Poco/URI.h"

#include "Poco/SharedPtr.h"

#include "Poco/Exception.h"

#include "Poco/Net/HTTPStreamFactory.h"

#include "Poco/Net/HTTPSStreamFactory.h"

#include "Poco/Net/FTPStreamFactory.h"
