Mysql IBM Worklight-使用IP地址而不是本地主机时无法连接到数据库

我目前正在创建一个Worklight应用程序，从我的计算机的MySQL数据库中检索一些数据

当我尝试运行应用程序时，它无法连接到数据库。当我将数据库的URL更改为IP地址（192.168.6.1（我的计算机的本地主机））时，会发生错误

当我通过调用worklight过程（地址为localhost）从我的计算机上测试它时，它工作正常，但当我将URL更改为IP地址时，它显示一个错误：

我不知道您使用的是哪个数据库前端，但您需要转到“用户创建/权限”屏幕，确保您已授予用户“root”权限以连接到

localhost

和

%

（全部），以便IP地址也被接受

例如：

root@%

而不是

root@localhost

提到这一点

顺便说一句，您可以将其保留为本地主机而不是IP地址（只要您在本地网络中进行测试）。这对设备来说不重要。你试过了吗？

对不起，我不知道如何实现。我使用jdbc连接访问mysql数据库，并使用phpmyadmin管理数据库是的，我尝试使用localhost作为IP地址来测试它，但它不起作用，然后您需要找出它。阅读phpmyadmin文档。谷歌快速搜索会发现这个问题。运行谷歌搜索。太好了，在我改变特权后，它终于起作用了。谢谢！
