現在網站用https的服務器越來越多了，在編寫程序的時候往往會遇到證書驗證錯誤。也就是SSLException錯誤。下面給出解決方案：

private static DefaultHttpClient getHttpClient() {try {// 禁止https證書驗證KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());trustStore.load(null, null);SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);//運行所有的hostname驗證HttpParams params = new BasicHttpParams();HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);// 禁用Cookie2請求頭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);}} 通過上述方法獲取得到的DefaultHttpClient ,通過該HttpClient再次進行網絡請求就能繞過證書驗證。該方法需要導入Apache的網絡包：org.apache.http.legacy.jar
