HTML：

public class MainActivity extends AppCompatActivity {

private BluetoothAdapter mBluetoothAdapter;
private BluetoothDevice mDevice;
private ConnectThread mConnectThread;
private String MAC = "30:14:10:17:06:93";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    TextView supportsBTorNot = (TextView) findViewById(R.id.supportsBTorNot);
    TextView listPairedDevices = (TextView) findViewById(R.id.listPairedDevices);

    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

    if (mBluetoothAdapter == null) {
        supportsBTorNot.setText("The device does not support bluetooth.");
    }
    else{
        if (!mBluetoothAdapter.isEnabled()) {
            Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableBtIntent, 1);
        }
        else{
            supportsBTorNot.setText("The device supports bluetooth.");
        }
    }

    Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
    listPairedDevices.setText(pairedDevices.toString());
    if (pairedDevices.size() > 0) {
        for (BluetoothDevice device : pairedDevices) {
            if(device.getAddress().equals(MAC)) {
                mDevice = device;
                break;
            }
        }
    }
    if (mDevice == null) {
        //Device is not paired yet
        //Need to initiate a connection request
    }

    mConnectThread = new ConnectThread(mDevice);
    mConnectThread.start();
}


private class ConnectThread extends Thread {

    private final BluetoothSocket mmSocket;
    private ConnectedThread mConnectedThread;
    private final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");

    TextView socketConnected = (TextView) findViewById(R.id.socketConnected);

    public ConnectThread(BluetoothDevice device) {
        BluetoothSocket tmp = null;
        try {
            tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
        } catch (IOException e) { }
        mmSocket = tmp;
    }

    public void run() {
        mBluetoothAdapter.cancelDiscovery();
        try {
            mmSocket.connect();
        } catch (IOException connectException) {
            try {
                mmSocket.close();
            } catch (IOException closeException) { }
            return;
        }
        if (mmSocket.isConnected()) {
            socketConnected.setText("The socket is established successfully.");
        }
        else {
            socketConnected.setText("The socket could not be stablished.");
        }

        mConnectedThread = new ConnectedThread(mmSocket);
        mConnectedThread.start();
    }
}

JS：

<html>
<head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
    <script src="myapp.js"></script>
</head>
<body ng-app="myapp">
    <div ng-controller="mainctrl">
      {{query}}
      <iframe ng-src="https://www.google.be/search?q={{query}}"></iframe>
    </div>
</body>
</html>

当在小提琴之外做以上操作时，我在控制台中得到以下js错误：

var app = angular.module('myapp', []);

app.config(function($sceDelegateProvider) {
  $sceDelegateProvider.resourceUrlWhitelist([
    'self',
    'https://www.google.be/**'
  ]);
});

app.controller('mainctrl', function MainController($scope) {
  $scope.query = "javascript";
});

这很奇怪，因为我是白名单＆＃34; https://www.google.be/ **＆＃34;正如我的小提琴所证明的那样。

为什么白名单没有任何影响？

Answer 1

我认为ng-src不适用于$ sce。在小提琴中将ng-src更改为ng-bind-html。

  <iframe ng-bind-html="https://www.google.be/search?q={{query}}"></iframe>

$ sceDelegateProvider资源网址白名单无效
