1为用户创建JWT RSA256证书 利用postman工具发送restfull请求
请求地址：http://${konghost}:8001/consumers/${consumerId}/jwt
1.1添加header内容
[{"key":"Content-Type","value":"application/x-www-form-urlencoded"}]
1.2利用openssl命令生成RSA私钥和公钥 1.2.1生成私钥 ssh-keygen -t rsa -b 4096 -f jwtRS256.key
# Don't add passphrase,无需设置密码
1.2.2用私钥生成公钥 openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
1.2.3检查私钥是否成功生成 cat jwtRS256.key
检查公钥是否成功
cat jwtRS256.key.pub
1.2.4粘贴并复制公钥 以下是我复制的:
