CloseableHttpClient 设置授权信息

private static int imcPort = Integer.parseInt(ConfigUtils.getNodeText("IMCPort"));
private static String imcIp = ConfigUtils.getNodeText("IMCIp");
static String imcUserName = ConfigUtils.getNodeText("IMCUserName");
static String imcPassword = ConfigUtils.getNodeText("IMCPassword");

static String url = "http://" + imcIp + ":" + imcPort + "/imcrs/";

CloseableHttpClient  设置用户名及密码授权信息

CloseableHttpClient httpclient = HttpClients.createDefault();

 HttpHost targetHost = new HttpHost(imcIp, imcPort, "http");

 StringBuffer uri = new StringBuffer(url + "plat/res/devAppend/getAppendByDid/" + id);

   HttpGet httpGet = new HttpGet(uri.toString().trim());

   CredentialsProvider credsProvider = (CredentialsProvider) new BasicCredentialsProvider();
   credsProvider.setCredentials(
           new AuthScope(imcIp, imcPort),
           new UsernamePasswordCredentials(imcUserName, imcPassword));
    
   // Create AuthCache instance
   AuthCache authCache = new BasicAuthCache();
   // Generate BASIC scheme object and add it to the local auth cache
   BasicScheme basicAuth = new BasicScheme();
   authCache.put(targetHost, basicAuth);
    
   // Add AuthCache to the execution context
   HttpClientContext context = HttpClientContext.create();
   context.setCredentialsProvider(credsProvider);
   context.setAuthCache(authCache);
   httpGet.addHeader("accept", "application/xml");
   CloseableHttpResponse response =null;

   response = httpclient.execute(
           targetHost, httpGet, context);
int statusCode = response.getStatusLine().getStatusCode();

String xmlContent = EntityUtils.toString(response.getEntity(), HTTP.UTF_8);

引入的类如下

import java.net.URLEncoder;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


import org.apache.commons.codec.binary.Base64;
import org.apache.commons.httpclient.HttpStatus;
