Android Volley Https SSL 自签名和 Google Maps API

我们正在使用 Android Volley 并使用可以正常工作的自认证 SSL，但现在我们想要实现 Google 地图，但它不起作用；它只是不会抛出任何错误，它只是显示一个灰色的屏幕

This is our implementation of Volley:

public class AppSingleton {
private static AppSingleton mAppSingletonInstance;
private RequestQueue mRequestQueue;
private static Context mContext;

private AppSingleton(Context context) {
    mContext = context;
    mRequestQueue = getRequestQueue();
}

public static synchronized AppSingleton getInstance(Context context) {
    if (mAppSingletonInstance == null) {
        mAppSingletonInstance = new AppSingleton(context);
    }
    return mAppSingletonInstance;
}

private RequestQueue getRequestQueue() {
    if (mRequestQueue == null) {
        mRequestQueue = Volley.newRequestQueue(mContext.getApplicationContext(), new HurlStack(null, getSocketFactory()));
    }
    return mRequestQueue;
}

public <T> void addToRequestQueue(Request<T> req, String tag) {
    req.setTag(tag);
    getRequestQueue().add(req);
}

这是我们的 getSocketFactory：

private SSLSocketFactory getSocketFactory() {

CertificateFactory cf = null;
try {
    cf = CertificateFactory.getInstance("X.509");
    InputStream caInput = mContext.getResources().openRawResource(OUR_CERT);
    Certificate ca;
    try {
        ca = cf.generateCertificate(caInput);
        Log.e("CERT", "ca=" + ((X509Certificate) ca).getSubjectDN());
    } finally {
        caInput.close();
    }


    String keyStoreType = KeyStore.getDefaultType();
    KeyStore keyStore = KeyStore.getInstance(keyStoreType);
    keyStore.load(null, null);
    keyStore.setCertificateEntry("ca", ca);


    String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
    TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
    tmf.init(keyStore);


    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {

            Log.e("CipherUsed", session.getCipherSuite());
            return hostname.compareTo("OUR_SERVER_HOSTNAME")==0;

        }
    };


    HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);
    SSLContext context = null;
    context = SSLContext.getInstance("TLS");

    context.init(null, tmf.getTrustManagers(), null);
    HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());

    SSLSocketFactory sf = context.getSocketFactory();


    return sf;

} catch (CertificateException | NoSuchAlgorithmException | KeyStoreException | IOException | KeyManagementException e) {
    e.printStackTrace();
}

return  null; }

MapActivity 是 Android Studio 创建的通用活动：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps2);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}}

及其位置：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="cat.amb.parcandride.MapsActivity" />

在activity_maps.xml中

我们如何实现地图活动？谢谢你！

尝试将谷歌地图客户端调用添加到 hostnameVerifier：

return hostname.compareTo("OUR_SERVER_HOSTNAME")==0 ||主机名.compareTo("clients4.google.com") == 0;

由于某种原因，一旦使用 HostnameVerifier 类，对 API 的调用就会被您的代码捕获。
