httpclient發起https請求以及擷取https返回內容,httpclienthttps
工作中的需要,使用Apache httpclient發起擷取通過https返回的內容,試了很多網上的解決辦法都不行,查閱了Apache httpclient的官方文檔,最後終於找出解決方案,分享給需要的朋友,免得走彎路。
使用時,調用getSSL方法即可擷取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);}
