cpprestsdk https双向认证小测

概述

因项目需要在系统中引入https双向认证，由于程序使用C/C++和cpprestsdk库编写，从网上经过一顿检索折腾，总算测试通过，故而博文记录用以备忘。

系统环境

Ubuntu 22.04.3 LTS
libcpprest-dev（jammy,now 2.10.18-1build2 amd64)

步骤

参考自签名根证书、中间证书、服务器证书生成流程详解，生成根证书、服务器证书以及客户端证书，然后用根证书对服务器、客户端的证书进行签名
编写代码，具体代码看后面
测试
测试可以使用curl
curl命令

curl -v -k --cacert root_cert.pem --cert client_cert.pem --key client_key.pem https://ip:port/

注意：
使用自签名证书的时候，服务器端的证书Common Name字段一定要填写对应的IP，不然会出现SSL握手失败的情况。

服务端代码

}
