在esp_tls_cfg_t结构体中,用于设置服务器验证选项的成员是.verify_peer。这个成员是一个布尔值,用于指定是否验证服务器的证书。 3. 理解服务器验证在TLS连接中的重要性 服务器验证是TLS连接中的一个重要环节。它确保客户端连接到的服务器是可信的,并且其身份已经通过证书链得到了验证。如果关闭了服务器验证,客户...
I have stumbled upon a problem in the last step of my esp32 project with this error. This error occurs when I am calling esp_http_client_perform(client) API. ESP-IDF monitor provides the following message: E (36765) esp-tls: couldn't get hostname for :example.com: getaddrinfo() ret...

答案是因为浏览器厂商已经帮助我们兼容好了,但当你要通过嵌入式IOT设备或者单片机实现https访问的时候,你就需要处理TLS证书的问题了。 因为ESP32的开源代码比较清晰简洁,所以我们今天的原理讲解,以ESP32为硬件平台,其他硬件也是类似的流程,你只要实现自己的过程,替换底层的socket等相关接口就可以实现类似的效果。
怎样在ESP8266上使用TLS V1.2 步骤1:安装Super House Esp-open-rtos 首先,按照SupeHouse Github上的说明安装SDK。 输入SDK根目录(我的目录为/opt/Espressif/esp-open-rtos)并测试安装通过刷新许多示例之一,我建议“闪烁”: $ make flash -j4 -C示例/闪烁ESPPORT =/dev/ttyUSB0...
