我认为您的问题在于dbHost变量，对于设备的连接，它需要有一个IP地址，我估计您以前在dbHost上有LocalHost，这就是它工作的原因，因此解决方案是获取应用程序使用的数据库的IP地址，并将其放在代码上。当然，不建议您在主机上使用静态IP，因为如果数据库的IP发生变化，您将不得不用新的IP重新写入dbHost值，这是什么错误？注册用户和身份验证用户并返回0Hi kiren siva help Me当您连接到网络时，您的意思是localhost不起作用，是吗？不是，它在localhost中起作用。主主机进入服务器时，它不起作用，可以吗请给出一些示例$dbHost=“192.168.1.101”$dbUsername=“user”$dbPassword=“”$dbName=“dbChat”；
