如何在多网络情况下，强制使用某一个网络，例如在wifi的连接状态下，强制使用移动网络上网？

Android原生的代码中是可以将手机在wifi的情况下强制使用移动网络，
Android中原生代码：

private void forceSendRequestByMobileData() {
ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkRequest.Builder builder = new NetworkRequest.Builder();
builder.addCapability(NET_CAPABILITY_INTERNET);
//强制使用蜂窝数据网络-移动数据
builder.addTransportType(TRANSPORT_CELLULAR);
NetworkRequest build = builder.build();
connectivityManager.requestNetwork(build, new ConnectivityManager.NetworkCallback() {
@Override
public void onAvailable(Network network) {
super.onAvailable(network);
try {
URL url = new URL("");
HttpURLConnection connection = (HttpURLConnection)network.openConnection(url);
/省略参数配置/
connection.connect();
/数据流处理/
} catch (Exception e) {

            }  

        }  
    });

在mui中应该如何写呢？ios又该怎么处理？

                var MainActivity = plus.android.runtimeMainActivity();  
                var Context = plus.android.importClass('android.content.Context');  
                var ConnectivityManager = plus.android.importClass("android.net.ConnectivityManager");  
                var NetworkRequest = plus.android.importClass("android.net.NetworkRequest");  
                var NetWork = plus.android.importClass('android.net.Network');  
                var connectivityManager = MainActivity.getSystemService(Context.CONNECTIVITY_SERVICE);  
                var NetworkCapabilities = plus.android.importClass("android.net.NetworkCapabilities");  
                var builder = new NetworkRequest.Builder();  
                builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);  
                //强制使用蜂窝数据网络-移动数据  
                builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);  
                var networkRequest = builder.build();  
                var myCallback = plus.android.newObject("android.net.ConnectivityManager$NetworkCallback");  

                console.log(JSON.stringify(myCallback));  
                myCallback.onAvailable = function(network) {  
                    console.log("onAvailable:  ");  
//                  connectivityManager.bindProcessToNetwork(network);  
                }     

回调方法我就不知道怎么写了？主要是那个network对象拿不到？怎么处理呢
