私はこれらの質問を参照しています：java.net.SocketExceptionが：接続リセット（SSL）
私はすべての提案HTTPSプロトコルを処理するために、2つ目の質問から解決策を使用：
System.getProperties().setProperty("https.protocols", "TLSv1.2,TLSv1.1,TLSv1,SSLv3");
フルコード：
/**
* Opens HTTP/HTTPS and setup connection to given URL.
*
* @return prepared HttpURLConnection connection
* @throws IOException in case URL is malformed or connection cannot be established
*/
public void openHttpUrlConnectionForGet() throws IOException {
// Set Https protocols
System.getProperties().setProperty("https.protocols", "TLSv1.2,TLSv1.1,TLSv1,SSLv3");
// Create connection
URL urlObject = new URL(location);
HttpURLConnection conn;
if (proxy != null) {
InetSocketAddress adr = new InetSocketAddress(proxy.getPk().getAddress(), proxy.getPk().getPort());
java.net.Proxy prx = new java.net.Proxy(java.net.Proxy.Type.HTTP, adr);
conn = (HttpURLConnection) urlObject.openConnection(prx);
} else {
conn = (HttpURLConnection) urlObject.openConnection();
}
conn.setRequestMethod("GET");
conn.setInstanceFollowRedirects(false);
// Setup SSL factory
if (conn instanceof HttpsURLConnection) {
HttpsURLConnection httpsc = (HttpsURLConnection) conn;
if (hostnameVerifier != null) {
httpsc.setHostnameVerifier(hostnameVerifier);
}
if (trustManager != null) {
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, new TrustManager[]{trustManager}, new java.security.SecureRandom());
httpsc.setSSLSocketFactory(sc.getSocketFactory());
} catch (KeyManagementException | NoSuchAlgorithmException e) {
throw new RuntimeException("Cannot init HTTPS connection.", e);
}
}
}
// Configure timeouts
conn.setConnectTimeout(connectTimeout);
conn.setDefaultUseCaches(false);
conn.setUseCaches(false);
conn.setDoOutput(false);
conn.setReadTimeout(readTimeout);
// Check connection
if (StringUtils.isEmpty(userAgent)) {
throw new IllegalArgumentException("Cannot create HTTP(S) connection. User-Agent header is not set.");
}
if (StringUtils.isEmpty(accept)) {
throw new IllegalArgumentException("Cannot create HTTP(S) connection. Accept header is not set.");
}
if (StringUtils.isEmpty(acceptLanguage)) {
throw new IllegalArgumentException("Cannot create HTTP(S) connection. Accept-Language header is not set.");
}
if (StringUtils.isEmpty(acceptEncoding)) {
throw new IllegalArgumentException("Cannot create HTTP(S) connection. Accept-Encoding header is not set.");
}
// Set headers
conn.setRequestProperty("User-Agent", userAgent);
conn.setRequestProperty("Accept", accept);
conn.setRequestProperty("Accept-Language", acceptLanguage);
conn.setRequestProperty("Accept-Encoding", acceptEncoding);
conn.setRequestProperty("Connection", "keep-alive");
conn.setRequestProperty("Upgrade-Insecure-Requests", "1");
if (cookies != null) {
conn.setRequestProperty("Cookie", cookies);
}
this.connection = conn;
}
私はまだ受け取っしかし：

これは、例えば、私はブラウザ経由で開くことができますが、JavaのHttpConnectionを経由開くことができない問題のサイトです：
