Xampp 拒绝与XMAPP localhost进行nodeMCU连接

我的项目是使用来自传感器DHT11的nodeMCU测量值，并将值发送到数据库Mysql。我使用xampp作为服务器。我无法将值发送到数据库。 nodeMCU可以读取值和发送值。但HTTP GET失败。返回connect REJECTED。我想可能在监听端口方面有问题

这是我的密码

#包括

这是串行端口造成的。
String url=“localhost
应替换为
String url=“
，因为Web服务器显然没有在ESP8266上运行。
您是否可以将此错误添加为问题的一部分，以便将来图像不再可用，我们仍然可以知道错误？谢谢！你认为localhost指向哪里？@c-preaw你还在坚持吗？
