// Note: read the following description before running this example
// 1. cmd into the "tls" folder, generate certificate by the following commands.
// (more details read the https://milvus.io/docs/tls.md)
//   chmod +x gen.sh
//   ./gen.sh
//
// 2. Configure the file paths of server.pem, server.key, and ca.pem for the server in config/milvus.yaml.
//    Set tlsMode to 1 for one-way authentication. Set tlsMode to 2 for two-way authentication.
// (read the doc to know how to config milvus: https://milvus.io/docs/configure-docker.md)
//    tls:
//        serverPemPath: [path_to_tls]/tls/server.pem
//        serverKeyPath: [path_to_tls]/tls/server.key
//        caPemPath: [path_to_tls]/tls/ca.pem
//
//    common:
//        security:
//            tlsMode: 2
//
// 3. Start milvus server
// 4. Run this example.
//    Connect server by oneWayAuth() if the server tlsMode=1, connect server by twoWayAuth() if the server tlsMode=2.
