class WiFiSSLClient
成员
公共构造函数 | | |
构建 WiFiSSLClient 实例，该实例始终以 SSL 方式连接指定的 IP 地址和端口。 | ||
公共方法 | | |
连接到 IP 地址和端口。 | ||
向服务器写入数据（单字节）。 | ||
读取 Wi-Fi SSL 插口的可用性。 | ||
从服务器读取输入的字节。 | ||
从当前数据包中获取下一个字节，而不转到下一个字节。 | ||
清除所有已写入客户端但尚未读取的字节。 | ||
断开与服务器的连接。 | ||
检查 SSL 客户端是否已连接。 | ||
为身份验证设置 CA 根证书。 | ||
设置客户端证书。 | ||
设置接收超时。 | ||
设置用于身份验证的预共享密钥 （PSK）。 | ||
