HarmonyOS 真机运行socket.UDPSocket.send 报没有权限，但是ability这边已经配置了网络权限

操作步骤：

1、入口模块配置权限如下：

"requestPermissions": [
  {
    "name": "ohos.permission.INTERNET",
    "reason": "$string:internet_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "inuse"
    }
  },
  {
    "name": "ohos.permission.GET_NETWORK_INFO",
    "reason": "$string:network_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "inuse"
    }
  }
]

2、并在自建feature下面的一个子模块引用common下的connection模块，发送广播步骤如下：

a. 先绑定，并且返回成功：

const udp = socket.constructUDPSocketInstance()
udp.bind({
  address: '0.0.0.0'
}

b. 然后发广播失败：

const address: socket.NetAddress = {
  address: "192.168.1.255",
  port: 9010
}

const sendOptions: socket.UDPSendOptions = {
  data: "discover mote._tcp 9010",
  address: address
}

udp.send(sendOptions, (err: BusinessError) => {
  if (err) {
    // 来到这里，报无权限
    Logger.error(`send fail: ${err.message}`);
    return;
  }
}
