javax.net.ssl.SSLException:hostname in certificate didn't match

终于建了一个自己个人小站：https://huangtianyu.gitee.io，以后优先更新小站博客，欢迎进站，O(∩_∩)O~~

现在网站用https的服务器越来越多了，在编写程序的时候往往会遇到证书验证错误。也就是SSLException错误。下面给出解决方案：

private static DefaultHttpClient getHttpClient() {
        try {
            // 禁止https证书验证
            KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            trustStore.load(null, null);
            SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);
            sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);//运行所有的hostname验证

            HttpParams params = new BasicHttpParams();
            HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
            HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

            // 禁用Cookie2请求头
            HttpClientParams.setCookiePolicy(params, CookiePolicy.RFC_2109);
            HttpClientParams.setCookiePolicy(params, CookiePolicy.BROWSER_COMPATIBILITY);
            HttpClientParams.setCookiePolicy(params, CookiePolicy.NETSCAPE);

            SchemeRegistry registry = new SchemeRegistry();
            registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
            registry.register(new Scheme("https", sf, 443));

            ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

            HttpConnectionParams.setConnectionTimeout(params, 3000);
            HttpConnectionParams.setSoTimeout(params, 5000);

            return new DefaultHttpClient(ccm, params);
        } catch (Exception e) {
            HttpParams httpParams = new BasicHttpParams();
            HttpConnectionParams.setConnectionTimeout(httpParams, 3000);
            HttpConnectionParams.setSoTimeout(httpParams, 5000);

            return new DefaultHttpClient(httpParams);
        }
    }
