• 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

    public class TrustAnyTrustManager implements X509TrustManager {
    	public void checkClientTrusted(X509Certificate[] chain, String authType)
    			throws CertificateException {
    	}
     
    	public void checkServerTrusted(X509Certificate[] chain, String authType)
    			throws CertificateException {
    	}
     
    	public X509Certificate[] getAcceptedIssuers() {
    		return new X509Certificate[] {};
    	}
    }

    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();
