HTTPS请求异常

今天使用自己写的HTTP工具发现访问https://www.acgist.com时，提示：

Exception in thread "main" java.net.SocketException: Connection reset
	at java.net.SocketInputStream.read(SocketInputStream.java:196)
	at java.net.SocketInputStream.read(SocketInputStream.java:122)

之前是没有问题的，怎么突然就提示这个错误，原来前几天我升级了一下Nginx的HTTPS协议版本，去掉了旧的SSL，所以以前的代码也要修改：

//SSLContext context = SSLContext.getInstance("SSL"); // 旧版本
SSLContext context = SSLContext.getInstance("TLSv1.2"); // 升级版本

如果是使用Apache的HTTPClient工具：

	private static SSLConnectionSocketFactory createSSLConnSocketFactory() {
		SSLContext sslContext = null;
		SSLConnectionSocketFactory sslFactory = null;
		try {
			sslContext = org.apache.http.ssl.SSLContextBuilder.create().loadTrustMaterial(null, new TrustStrategy() {
//			支持TLS
//			sslContext = org.apache.http.ssl.SSLContextBuilder.create().useProtocol("TLSv1.2").loadTrustMaterial(null, new TrustStrategy() {
				// 信任所有证书
				public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
					return true;
				}
			}).build();
		} catch (Exception e) {
			logger.error("创建SSL工程异常", e);
		}
		sslFactory = new SSLConnectionSocketFactory(sslContext, new HostnameVerifier() {
//		支持TLS
//		sslFactory = new SSLConnectionSocketFactory(sslContext, new String[] {"TLSv1.2"}, null, new HostnameVerifier() {
			@Override
			public boolean verify(String hostname, SSLSession session) {
				return true; // 不检查证书和域名是否匹配
			}
		});
		return sslFactory;
	}

同样可能还有一个问题，就是SVN提交更改时提示502错误：

    RA layer request failed
svn: Commit failed (details follow):
svn: COPY request on '/!svn/bc/1059/projects/trunk/acgist_www/src/main/java/com/acgist/bean/dto/URLRepeat.java' failed: 502 Bad Gateway

这个需要修改Apache配置：

#下面的模块默认已经加载
LoadModule headers_module modules/mod_headers.so

#修改httpd.conf，在最后添加
<IfModule headers_module>
    RequestHeader edit Destination ^https: http: early
</IfModule>
