在微服務框架之外的系統中，我們經常會遇到使用httpClient進行接口調用的問題，除了進行白名單的設置，很多時候我們需要在接口調用的時候需要身份認證。翻了一下官方文檔，解決方法很多，但是都不太符合實際業務場景，這里提供一種簡單粗暴的解決方法。
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;
}
}
