@correctness/listen-default-network-change

建议应用监听默认网络的变化，关闭原有网络的数据传输，并使用新网络建立数据传输。

该规则仅在联网类应用检查整个工程时才生效。

规则配置

// code-linter.json5
{
  "rules": {
    "@correctness/listen-default-network-change": "suggestion"
  }
}

选项

该规则无需配置额外选项。

正例

// With the ohos.permission.GET_NETWORK_INFO permission configured
import connection from '@ohos.net.connection';
export function test() {
  const defaultNet = connection.getDefaultNetSync();
  const netCapabilities = connection.getNetCapabilitiesSync(defaultNet);
  let bearerTypes = netCapabilities.bearerTypes;
  const netConnection = connection.createNetConnection();
  netConnection.on('netCapabilitiesChange', (netCap: connection.NetCapabilityInfo) => {
    const newBearTypes = netCap.netCap.bearerTypes;
    if (newBearTypes !== bearerTypes) {
      bearerTypes = newBearTypes;
    }
  });
}

反例

// With the ohos.permission.GET_NETWORK_INFO permission configured
// import connection from '@ohos.net.connection';
// The `on(type: 'netCapabilitiesChange', callback: Callback<connection.NetCapabilityInfo>)`, `getDefaultNet`/`getDefaultNetSync` and `getNetCapabilities`/`getNetCapabilitiesSync` functions are not called.
