HTTPClient工具访问HTTPS时证书和域名不符

如果使用HTTPClient工具时，请求的域名和颁发证书时的域名不一样时会提示：

javax.net.ssl.SSLPeerUnverifiedException: Host name 'www.acgist.com' does not match the certificate subject provided by the peer (CN=static.acgist.com)

这个问题，我们只需要在构建SSLConnectionSocketFactory时忽略一下证书就可以了。

常用的如下，是需要检测证书和域名的：

private static SSLConnectionSocketFactory createSSLConnSocketFactory() {
	SSLContext sslContext = null;
	SSLConnectionSocketFactory sslFactory = null;
	try {
		sslContext = org.apache.http.ssl.SSLContextBuilder.create().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);
	return sslFactory;
}

修改后忽略这个检查：

private static SSLConnectionSocketFactory createSSLConnSocketFactory() {
	SSLContext sslContext = null;
	SSLConnectionSocketFactory sslFactory = null;
	try {
		sslContext = org.apache.http.ssl.SSLContextBuilder.create().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() {
		@Override
		public boolean verify(String hostname, SSLSession session) {
			return true; // 不检查证书和域名是否匹配
		}
	});
	return sslFactory;
}
