为您更新NullPointerException
从你的logcat信息，getResources() in GetCert.getThisCert()导致 NullPointerException。看来你还没有通过Context从你的Activity to GetCert班级。因此，请更新您的代码并检查结果。
更新结束
你可以参考我下面的代码：
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) {
e.printStackTrace();
}
}
}
};
}
private SSLSocketFactory getSSLSocketFactory_Certificate(String keyStoreType, int keystoreResId)
throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException {
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream caInput = getResources().openRawResource(keystoreResId);
Certificate ca = cf.generateCertificate(caInput);
caInput.close();
if (keyStoreType == null || keyStoreType.length() == 0) {
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);
TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, wrappedTrustManagers, null);
return sslContext.getSocketFactory();
}
private SSLSocketFactory getSSLSocketFactory_KeyStore(String keyStoreType, int keystoreResId, String keyPassword)
throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException {
InputStream caInput = getResources().openRawResource(keystoreResId);
// creating a KeyStore containing trusted CAs
if (keyStoreType == null || keyStoreType.length() == 0) {
keyStoreType = KeyStore.getDefaultType();
}
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(caInput, keyPassword.toCharArray());
// creating a TrustManager that trusts the CAs in the KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, wrappedTrustManagers, null);
return sslContext.getSocketFactory();
}
然后调用以下两个之一（一个用于密钥库文件，另一个用于证书文件）：
SSLSocketFactory sslSocketFactory = getSSLSocketFactory_KeyStore("BKS", R.raw.androidbksv1, "123456789");
SSLSocketFactory sslSocketFactory = getSSLSocketFactory_Certificate("BKS", R.raw.androidbksv1_cert);
因为你有PKCS12文件，您可以使用以下两个之一：
SSLSocketFactory sslSocketFactory = getSSLSocketFactory_KeyStore("PKCS12", R.raw.androidpkcs12, "123456789");
SSLSocketFactory sslSocketFactory = getSSLSocketFactory_Certificate("PKCS12", R.raw.androidpkcs12_cert);
上面的代码已经在我的HTTPS项目中测试成功。希望这可以帮助！
另外，请澄清一下The last one actually crashes the app...，发布更多代码和 logcat 信息（如果有）。
