javax.net.ssl.SSLProtocolException

我一直在https上进行本地测试。 这是我的密码

private static void disableSSLCertificateChecking() {
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        @Override
        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }

        @Override
        public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }
    } };

    try {
        SSLContext sc = SSLContext.getInstance("TLS");

        sc.init(null, trustAllCerts, new java.security.SecureRandom());

        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

这就是我所要求的

        protected Void doInBackground(String... urls) {

        try {

            if(Some condition){
                disableSSLCertificateChecking();

                URL url = new URL(host+"discovery.jsp");
                HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
                conn.setDoInput(true);
                conn.setDoOutput(true);

                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));

我在conn.getOutputStream（）处遇到异常。我以前使用过httpclient。现在迁移时遇到问题。” 请帮忙

这就是我以前使用它的方式

private static void disableSSLCertificateChecking() {
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        @Override
        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }

        @Override
        public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }
    } };

    try {
        SSLContext sc = SSLContext.getInstance("TLS");

        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (KeyManagementException e) {           
    } catch (NoSuchAlgorithmException e) {            
    }
}

及

任何帮助都将不胜感激

谢谢

您还可以提供stacktrace吗？您正在尝试创建一个到仅接受TLS连接的服务器的SSLv2/SSLv3连接。可能是设备使用了旧的安卓版本？您应该检查SSLSocketFactory上启用了哪些协议。顺便说一句：禁用SSL/TLS的一半安全性不是一个好主意（接受所有证书，禁用HostNameVerifier）…重复问题>您是否也可以提供stacktrace？您正在尝试创建一个到仅接受TLS连接的服务器的SSLv2/SSLv3连接。可能是设备使用了旧的安卓版本？您应该检查SSLSocketFactory上启用了哪些协议。顺便说一句：禁用SSL/TLS的一半安全性不是一个好主意（接受所有证书，禁用HostNameVerifier）…重复问题>
