java - 使用从 ESP32 到 Spring Boot 安全 API 的预共享密钥

问题描述

我正在尝试将一些数据从 ESP32 设备发送到安全的 Spring Boot API。我正在尝试使用 Github WiFiClientPSK上提供的简单 WiFiClientPSK.ino 草图

它正在使用 client.setPreSharedKey(pskIdent, psKey); 设置预共享密钥

在服务器端，我已经设置了 Spring Boot 应用程序以接受 SSL 连接，并且我正在尝试在标头中获取 PSK。下面是代码

@RestController
public class WebController {
    @RequestMapping(value="/", method = {RequestMethod.GET,RequestMethod.POST})
    public String check(@RequestHeader HttpHeaders headers) {
        System.out.println("Header = "+headers.toString());
        return "";
    }
}

这是 SSL 配置

server.ssl.key-store-type=PKCS12
server.ssl.key-store=classpath:springboot.p12
server.ssl.key-store-password=password
server.ssl.key-alias=springboot
server.port=8443

当我在 DEVKIT 中安装草图后尝试从 SPE32 建立连接时，我在串行监视器上收到此错误

在 Spring Boot 应用程序上，我没有任何流量。有没有人这样做过或知道如何解决这个问题？
