javax.net.ssl.SSLProtocolException

Question

我一直在https上进行本地测试。 这是我的代码

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();
    }
}

这就是我要求的方式

        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（）处得到了异常。我以前使用的是httpclient。我现在正在迁移时出现问题。 请帮忙。

这就是我之前使用它的方式。

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) {            
    }
}

和

protected Void doInBackground(String... urls) {

    try {

        if(Some condition){
            disableSSLCertificateChecking();
            HttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(host + "discovery.jsp");

                SSLSocketFactory sf = (SSLSocketFactory)httpClient.getConnectionManager()
                        .getSchemeRegistry().getScheme("https").getSocketFactory();
                sf.setHostnameVerifier(new AllowAllHostnameVerifier());                    
                HttpResponse response = null;

                try {
                    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
                } catch (UnsupportedEncodingException e) {                                              
                }

                //making POST request.
                try {                  
                    response = httpClient.execute(httpPost);
                }

任何帮助都将不胜感激。

谢谢！
