工作中的需要，使用Apache httpclient发起获取通过https返回的内容，试了很多网上的解决办法都不行，查阅了Apache httpclient的官方文档，最后终于找出解决方法，分享给需要的朋友，免得走弯路。
使用时，调用getSSL方法即可获取https地址返回的内容。
代码如下：
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() {
@Override
public 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);
}
