http请求digest auth认证

1.post请求
public static String postMethod(String url, String query,String host) throws IOException {
   String content = null;
   //认证
   CloseableHttpClient httpclient=digestAuth(host);
   try {
      HttpPost postMethod = new HttpPost(url);
      StringEntity s = new StringEntity(query);
      s.setContentEncoding("utf-8");//编码
      s.setContentType("application/xml");
      postMethod.setEntity(s);
      HttpResponse response = httpclient.execute(postMethod);
      content = EntityUtils.toString(response.getEntity());
   } catch (Exception e) {
      System.out.println("推送失败：" + e);
   } finally {
      httpclient.close();
   }
   return content;
}

2.byte[]类型参数
public static String postMethodAnalysisImage(String url, byte[] binaryStreamsStr,String host) throws IOException {
   CloseableHttpClient httpclient=digestAuth(host);
   String content=null;
   try {
      HttpPost postMethod = new HttpPost(url);
      HttpEntity reqEntity = new ByteArrayEntity(binaryStreamsStr, ContentType.APPLICATION_JSON);
      postMethod.setEntity(reqEntity);
      StringEntity s = new StringEntity(reqEntity.toString());
      s.setContentEncoding("utf-8");//编码
      postMethod.setEntity(s);
      postMethod.setEntity(reqEntity);
      HttpResponse response = httpclient.execute(postMethod);
      content = EntityUtils.toString(response.getEntity());
   } catch (Exception e) {
      System.out.println("推送失败：" + e);
   }finally {
      httpclient.close();
   }
   return content;
}
3.HttpGet 请求
public static String getMethodFDLib(String url, String host) throws IOException {
   String content = null;
   CloseableHttpClient httpclient=digestAuth(host);
   try {
      HttpGet getMethod = new HttpGet(url);
      org.apache.http.HttpResponse response = httpclient.execute(getMethod);
      content = EntityUtils.toString(response.getEntity());
   } catch (Exception e) {
      System.out.println("推送失败：" + e);
   }finally {
      httpclient.close();
   }
   return content;
}  

private static CloseableHttpClient digestAuth(String host) {
   CredentialsProvider credsProvider = new BasicCredentialsProvider();
   credsProvider.setCredentials(
         new AuthScope(host, 80),//请求地址 + 端口号密码2b3e201690"));// 用户名 + 密码 （用于验证）
   CloseableHttpClient httpclient = HttpClients.custom()
         .setDefaultCredentialsProvider(credsProvider)
         .build();
   return httpclient;
}
