JSP开发中Apache-HTTPClient 用户验证的实例详解
JSP开发中Apache-HTTPClient 用户验证的实例详解前言：
在微服务框架之外的系统中，我们经常会遇到使用httpClient进行接口调用的问题，除了进行白名单的设置，很多时候我们需要在接口调用的时候需要身份认证。翻了一下官方文档，解决方法很多，但是都不太符合实际业务场景，这里提供一种简单粗暴的解决方法。
解决方法：利用请求头，将验证信息保存起来。
实现代码：
public class HttpClientUtils {
protected static final Logger LOG = LoggerFactory.getLogger(HttpClientUtils.class);
private static final String AUTHENKEY = "Authorization";
private static final String BASICKEY = "Basic ";
public static String getConnect(String url,String username,String password) {
CloseableHttpResponse response = null;
CloseableHttpClient client = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);
Base64 token = new Base64();
String authenticationEncoding = token.encodeAsString(new String(username + ":" + password).getBytes());
httpGet.setHeader(AUTHENKEY, BASICKEY + authenticationEncoding);
String responseContent = "";
try {
response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
responseContent = EntityUtils.toString(entity, "UTF-8");
} catch (IOException e) {
LOG.error(e.toString());
} finally {
if (response != null) {
try {
response.close();
} catch (IOException e) {
LOG.error(e.toString());
}
}
if (client != null) {
try {
client.close();
} catch (IOException e) {
LOG.error(e.toString());
}
}
}
return responseContent;
}
}
