工作中的需要，使用Apache?httpclient發(fā)起獲取通過https返回的內容，試了很多網(wǎng)上的解決辦法都不行，查閱了Apache?httpclient的官方文檔，最后終于找出解決方法，分享給需要的朋友，免得走彎路。

使用時，調用getSSL方法即可獲取https地址返回的內容。

代碼如下：

?

public static String getSSL(String url, String responseDecode) throws IOException {CloseableHttpClient httpclient = createSSLInsecureClient();CloseableHttpResponse response = null;String content = null;try {HttpGet httpget = new HttpGet(url);RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(5000).setConnectTimeout(5000).setConnectionRequestTimeout(5000).build();httpget.setConfig(requestConfig);response = httpclient.execute(httpget);HttpEntity entity = response.getEntity();if (entity != null) {content = EntityUtils.toString(entity);EntityUtils.consume(entity);}} catch (ParseException e) {logger.error("request URL[" + url + "] error", e);throw e;} catch (IOException e) {logger.error("request URL[" + url + "] error", e);throw e;} finally {if (response != null) {try {response.close();} catch (IOException e) {logger.error("", e);}}if (httpclient != null) {try {httpclient.close();} catch (IOException e) {logger.error("", e);}}}return content;}private static CloseableHttpClient createSSLInsecureClient() {try {SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {@Overridepublic boolean isTrusted(java.security.cert.X509Certificate[] arg0, String arg1) {return true;}}).build();SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);return HttpClients.custom().setSSLSocketFactory(sslsf).build();} catch (KeyManagementException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (KeyStoreException e) {e.printStackTrace();}return HttpClients.createDefault();}public static void main(String[] args) {ShiroUser user = UMSHelper.invoke("10001", "10102130023000");System.out.println(user);}
