HTTPS访问站点,出现证书问题解决(转载) 规格严格

用URLConnection获取一个Https站点的东西 老是抛出异常说证书认证不过 不过对服务迁移性的考虑 又不想导入证书到JRE里面(总不会说出现紧急情况 需要搬迁到其他服务器 还要我记得去导入证书吧) 最奇怪的是 Windows下运行的好好的 没有什么异常 一去Linux就出错
最后没有办法 只有 强制绕过这个检查了

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;
 
public class TrustAnyHostnameVerifier implements HostnameVerifier {
	public boolean verify(String hostname, SSLSession session) {
		// 直接Pass
		return true;
	}
}

就是要检查的时候 让他直接返回true 通过验证就OK了

在建立连接的时候 还要设置一下这个管理器

SSLContext context = SSLContext.getInstance("SSL");
context.init(null,new TrustManager[] { new TrustAnyTrustManager() },
		new SecureRandom());
// 获取URL 进行连接
URL url = new URL(urlString);
connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(context.getSocketFactory());
connection.setHostnameVerifier(new TrustAnyHostnameVerifier());
connection.connect();
