1.curl是什么
cURL（客户端URL）是一个开放源代码的命令行工具，用来请求 Web和其他各种类型的服务器。curl有着大量的参数，常用来测试/调试服务器的开发和排查等，堪称一个网络“神器”。
2.国密curl是什么
curl自身不支持国密SSL协议（TLCP）。程序员说：要有国密版curl，于是就有了国密版curl，哈哈，程序员就是软件世界的上帝啊。国密版curl，简称gmcurl，由国密SSL实验室（www.gmssl.cn）移植，并提供免费下载和使用。
3.国密curl使用（单向国密SSL）
3.1 简单执行
[root@206test ~]# ./gmcurl
GM Version: 1.0.0 Ported by www.gmssl.cn
Options:
--gmssl, use TLCP protocol
--cert, use sm2 sig pem cert
--key, use sm2 sig pem key
--cert2, use sm2 enc pem cert
--key2, use sm2 enc pem key
curl: try 'curl --help' or 'curl --manual' for more information3.2 简单访问
[root@206test ~]# ./gmcurl --gmssl -k https://ebssec.boc.cn
GM Version: 1.0.0 Ported by www.gmssl.cn
Options:
--gmssl, use TLCP protocol
--cert, use sm2 sig pem cert
--key, use sm2 sig pem key
--cert2, use sm2 enc pem cert
--key2, use sm2 enc pem key注释：
1）--gmssl表示启用国密SSL
2）-k表示不验证服务端证书
3.3 验证证书
[root@206test ~]# ./gmcurl --gmssl --cacert boc.ca.pem https://ebssec.boc.cn
GM Version: 1.0.0 Ported by www.gmssl.cn
Options:
--gmssl, use TLCP protocol
--cert, use sm2 sig pem cert
--key, use sm2 sig pem key
--cert2, use sm2 enc pem cert
--key2, use sm2 enc pem key注释：
1）--cacert表示加载本地可信证书链
2）boc.ca.pem下载地址为https://www.gmssl.cn/gmssl/down/boc.ca.pem
3.4 简单调试
[root@206test ~]# ./gmcurl --gmssl -k --verbose https://ebssec.boc.cn
GM Version: 1.0.0 Ported by www.gmssl.cn
Options:
--gmssl, use TLCP protocol
--cert, use sm2 sig pem cert
--key, use sm2 sig pem key
--cert2, use sm2 enc pem cert
--key2, use sm2 enc pem key

1）可以看到国密SSL国产的完整数据
2）可以把日志输出到文件
即./gmcurl --gmssl -k --trace ssl.log https://ebssec.boc.cn
4.国密curl使用（双向国密SSL）
4.1 生成用户国密双证书
4.2 使用用户国密双证书访问
[root@206test ~]# ./gmcurl --gmssl -k --cert ./sm2.user1.sig.crt.pem --key ./sm2.user1.sig.key.pem --cert2 ./sm2.user1.enc.crt.pem --key2 ./sm2.user1.enc.key.pem https://demo.gmssl.cn:1443
GM Version: 1.0.0 Ported by www.gmssl.cn
Options:
--gmssl, use TLCP protocol
--cert, use sm2 sig pem cert
--key, use sm2 sig pem key
--cert2, use sm2 enc pem cert
--key2, use sm2 enc pem key
