我试图将服务器和客户端证书以及私钥加载到运行但它没有连接到服务器我还附加了 BEARSSL 的日志。

日志： Wifi连接IP地址： 192.168.34.12

等待 NTP 时间同步：当前时间：10 月 27 日星期二 04:06:24 2020

正在连接到 192.168.15.123（服务器 ip）连接失败

错误code:56

Answer 1

您正在将 IP 地址作为 const char* 传递给 client.connect()，但该函数需要一个 4 字节的 IP 地址数组；它现在认为它正在获取一个 URL，它将尝试解析为一个 IP 地址（但失败）。

如果您声明任一

IPAddress host(192, 168, 15, 123); 或 const char* host = "hostname";

那么 client.connect(host, httpsPort); 就可以了；它不会理解这一点：

const char* host = "192.168.15.123";

I am trying to connect ESP8266 with HTTPS python server but ESP is not connecting with server and giving bearssl error code that server name is bad
