解決Jsoup或HttpClient 連 https 報錯：Remote host closed connection during handshake

報錯

主要報錯信息如下：
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
java.io.EOFException: SSL peer shut down

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

依賴

import javax.net.ssl.*;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

方法

/** 信任任何站點 */
public static void trustEveryone() {
    try {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, new X509TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            @Override
            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        } }, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
    } catch (Exception e) {
         e.printStackTrace();
    }
}

用法

直接在https發生連接代碼的前面加入 trustEveryone(); 即可

例如：

trustEveryone();
Jsoup.connect(url).get();

或者

trustEveryone();
CloseableHttpResponse response = httpclient.execute(httpget);

END

補充：用了這個方法以後，絕大部分情況可以正常，小概率還有可能觸發此報錯，初步猜測和網絡環境也有有一定關係。
用瀏覽器試了下，同一個網絡環境下瀏覽器能正常打開，基本就不會有問題。
