C++网络库cpp-netlib的安装
简单介绍
cpp-netlib是基于asio库的http网络库, 包含了HTTP/HTTPS客户端、服务端的接口支持
cpp-netlib安装位置
头文件一般安装在
1
| ${CMAKE_INSTALL_PREFIX}/include/boost/network
|
库文件(.a, .so)一般在
1
| ${CMAKE_INSTALL_PREFIX}/lib/
|
其中CMAKE_INSTALL_PREFIX是执行安装脚本时候设定的路径， 比如 CMAKE_INSTALL_PREFIX=/usr/local时, 以上的目录则变为
1
2
| /usr/local/include/boost/network
/usr/local/lib
|
写服务端程序时
需要包含的头文件
1
2
| #include <network/uri.hpp>
#include <boost/network/protocol/http/server.hpp>
|
需要引入的库
1

4
5
| target_link_libraries(app
boost_system
network-uri
cppnetlib-server-parsers
)
|
其中cppnetlib-server-parsers时服务端解析请求时所需要的库
network-uri是我们自己在解析请求参数的path、query、host、port、protocol等参数需要用到的库
boost_system是cppnetlib-server-parsers以及我们在使用cpp-netlib是调用的一些借口内部依赖的库
示例代码(C++11, cpp-netlib 版本: 0.12.0)
