使用X509TrustManager检查服务器是否可信时，我收到异常错误。我按照开发人员的说明进行了操作：https://developer.android.com/training/articles/security-ssl.html#UnknownCa
我正在尝试获取本地存储在我的应用程序中的证书，并将该证书与我所做的每个Volley API请求一起使用，以首先确认证书是否受信任（已验证）。我从GoDaddy下载了证书并添加到我的项目中：https://certs.godaddy.com/repository/。我得到的确切错误如下：

我有一个名为＆＃34; VolleyClient＆＃34;管理我通过Volley提出的所有请求。这是我的实施。我首先使用我的Volley请求队列传入一个HurlStack对象。
HurlStack hurlStack = new HurlStack() {
@Override
protected HttpURLConnection createConnection(URL url) throws IOException {
HttpsURLConnection httpsURLConnection = (HttpsURLConnection) super.createConnection(url);
try {
httpsURLConnection.setSSLSocketFactory(getSSLSocketFactory());
httpsURLConnection.setHostnameVerifier(getHostnameVerifier());
} catch (Exception e) {
e.printStackTrace();
}
return httpsURLConnection;
}
};
RequestQueue mRequestQueue = Volley.newRequestQueue(mContext.getApplicationContext(), hurlStack);
我有一个主机名验证器
/**
* This is used to verify local host. Let's assume the app is hosted inside of a server
* machine which has a server certificate in which "Issued to" is "localhost", then
* this method will verify "localhost". If not, can temporarily return true
* @return
*/
private HostnameVerifier getHostnameVerifier() {
return new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
//return true;
HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier();
return hv.verify("localhost", session);
}
};
}
private SSLSocketFactory getSSLSocketFactory()
throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException {
InputStream caInput = mContext.getResources().openRawResource(R.raw.gdig2); // this certificate file stored in \app\src\main\res\raw folder path
// From https://www.washington.edu/itconnect/security/ca/load-der.crt
//InputStream caInput = new BufferedInputStream(new FileInputStream("load-der.crt"));
CertificateFactory cf = null;
Certificate ca = null;
try {
cf = CertificateFactory.getInstance("X.509", "BC");
ca = cf.generateCertificate(caInput);
System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
} catch (NoSuchProviderException e) {
e.printStackTrace();
} finally {
caInput.close();
}
caInput.close();
// Create a KeyStore containing our trusted CAs
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType); //KeyStore keyStore = KeyStore.getInstance("BKS");
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
// Create a TrustManager that trusts the CAs in our KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());
// Create an SSLContext that uses our TrustManager
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, wrappedTrustManagers, null);
return sslContext.getSocketFactory();
}
private TrustManager[] getWrappedTrustManagers(TrustManager[] trustManagers) {
final X509TrustManager originalTrustManager = (X509TrustManager) trustManagers[0];
return new TrustManager[]{
new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
return originalTrustManager.getAcceptedIssuers();
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
try {
originalTrustManager.checkClientTrusted(certs, authType);
} catch (CertificateException e) {
e.printStackTrace();
}
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
try {
originalTrustManager.checkServerTrusted(certs, authType);
} catch (CertificateException e) {
// THIS IS THE EXCEPTION I GET WITH EACH REQUEST MADE
e.printStackTrace();
}
}
}
};
}
提前致谢！
编辑：当发出对Google的调用时会发生此异常，因为我使用的是谷歌地图。此调用不使用来自我的服务器的经过验证的证书，因此会导致信任锚未找到证书路径异常。我可以通过始终返回true来规避这一点，但这是正确的吗？我应该返回我的服务器域吗？
private HostnameVerifier getHostnameVerifier() {
return new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
// instead should I return back hv.verify("https:myserver.com", session);
return true;
}
};
}

检查系统时间。确保它是最新的。
