未找到证书路径的信任锚异常

Question

嗨，我正在尝试使用 https 在 tomcat 服务器和安卓应用程序之间建立 SSL 通信

1-我使用keytool为tomcat创建了一个密钥库文件

2-然后生成一个PEM文件以将其与keytool一起使用以生成BKS文件

3-雄猫服务器工作正常

基本上我遵循了这篇文章

问题是当我尝试使用HttpsURLConnection从Android应用程序连接时，我总是得到异常：

帮助！！

Answer 1

两种可能的解决方案

1） 如果您使用的是自签名证书，请尝试将证书 （.crt/.cer） 添加到信任库。

2） 如果您的证书由本地 CA 签名，请确保将根 CA 和中间 CA 导入信任存储区。

Answer 2

            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            InputStream caInput = getApplicationContext().getResources()
                    .openRawResource(R.raw.my_certificate);//new BufferedInputStream(is);
            Certificate ca;
            try {
                ca = cf.generateCertificate(caInput);
            } finally {
                caInput.close();
            }
            /** Create a KeyStore containing our trusted CAs **/
            String keyStoreType = KeyStore.getDefaultType();
            KeyStore keyStore = KeyStore.getInstance(keyStoreType);
            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);
            /** Create an SSLContext that uses our TrustManager **/
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, tmf.getTrustManagers(), null);

最后将 sslcontext 设置为 HttpsURLConnection
