java – 带有客户端证书的Android Http请求

try {
    /*** CA Certificate ***/

    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    InputStream caInput = getResources().openRawResource(R.raw.caserver);
    Certificate ca = cf.generateCertificate(caInput);
    System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());

    // Create a KeyStore containing our trusted CAs
    String keyStoreType = KeyStore.getDefaultType();
    KeyStore keyStore = KeyStore.getInstance(keyStoreType);
    keyStore.load(null,null);
    keyStore.setCertificateEntry("ca",ca);
    System.out.println(keyStoreType);

    // Create a TrustManager that trusts the CAs in our KeyStore
    String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
    TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
    tmf.init(keyStore);

    /*** Client Certificate ***/

    KeyStore keyStore12 = KeyStore.getInstance("PKCS12");
    InputStream certInput12 = getResources().openRawResource(R.raw.p12client);
    keyStore12.load(certInput12,"123456key".toCharArray());

    // Create a KeyManager that uses our client cert
    String algorithm = KeyManagerFactory.getDefaultAlgorithm();
    KeyManagerFactory kmf = KeyManagerFactory.getInstance(algorithm);
    kmf.init(keyStore12,null);


    /*** SSL Connection ***/

    // Create an SSLContext that uses our TrustManager and our KeyManager
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(kmf.getKeyManagers(),tmf.getTrustManagers(),null);

    URL url = new URL("https://myurl/test.json");
    HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
    urlConnection.setSSLSocketFactory(context.getSocketFactory());

    System.out.println("Weeeeeeeeeee");
    InputStream in = urlConnection.getInputStream(); // this throw exception
}
catch (Exception e) {
    e.printStackTrace();
}

当执行到达= urlConnection.getInputStream();中的最后一行InputStream时,我获得了下一个异常.

System.err: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

我花了很多时间来修复此错误,但我找不到任何信息.当我使用带有客户端证书的Web浏览器发出相同的请求时,一切正常.

有帮助吗？提前致谢.

我按照以下步骤生成证书：

> openssl req -config openssl.cnf -new -x509 -extensions v3_ca -days 3650 -keyout private/caserver.key -out certs/caserver.crt
> openssl req -config openssl.cnf -new -nodes -keyout private/client.key -out client.csr -days 1095
> openssl ca -config openssl.cnf -cert certs/caserver.crt -policy policy_anything -out certs/client.crt -infiles csr/client.csr
> openssl pkcs12 -export -clcerts -in certs/client.crt  -inkey private/client.key -out p12client.p12

在我的代码中,我使用caserver.crt和p12client.p12.
