ESP32S NodeMCU HTTP页面无法连接问题排查求助

• 硬件：ESP32S NodeMCU
• 开发环境：VSCode with PlatformIO

本人首次接触ESP32与Web服务器开发，若术语使用有误敬请谅解。当前正在开发业余ESP32项目，核心功能涉及HTTP页面交互：已编写if-else逻辑读取Web服务器URL后缀，以此设置waterState变量。目前ESP32可正常连接WiFi网络，但电脑端始终无法访问对应URL地址。预期效果为页面返回所选浇水时段（如morning），同时串口终端输出函数执行完成的提示。

已尝试调整WiFiClient与WiFiServer实例的位置，但未解决问题。此前将ScheduleProt相关代码放在WiFi连接逻辑内时程序可正常运行，现在复现该写法仍无法生效。

以下为项目各模块代码（代码、技术术语、标识符均保持原样）：

WiFiConnect.h #

#include <WiFiClient.h>

    #define WIFI_PASSWORD "Password"
    #define WIFI_TIMEOUT 20000
       
    public:
    void wifiConnect();
    void wifiDisconnect();

};

#endif

void WiFiConnect::wifiConnect() {

    WiFiServer server(80);

    Serial.print("Connecting to WiFi");
    WiFi.mode(WIFI_AP);
    WiFi.begin(WIFI_NETWORK, WIFI_PASSWORD);

    unsigned long startAttemptTime = millis();

    //Connection Protocol
    while(WiFi.status() != WL_CONNECTED && (millis() - startAttemptTime) < WIFI_TIMEOUT) {
        Serial.println("...");
        delay(100);
    }
    if(WiFi.status() != WL_CONNECTED) {
        Serial.println("Failed, attempting again...");
        delay(5000); 
        }
    else{
        Serial.print("Connected: ");
        Serial.println(WiFi.localIP());
        server.begin();
        }
    

}

  WiFi.disconnect();
}
