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 "Poco/Net/WebSocket.h"

#include "Poco/Net/HTTPClientSession.h"

#include "Poco/Net/HTTPRequest.h"
