https post設置代理發送請求

本文主要是對http和https 發送post請求所做工具類， 方法中有兩個參數：https(是否是https地址)和proxy(是否使用代理)。

http和https主要使用apache的基礎jar包,代理地址可從配置文件中獲取。好了，廢話不多說，直接上代碼：

1. https請求類

public class HttpProxyPost {
 private static Logger logger = LoggerFactory.getLogger(HttpProxyPost.class);
 private static PropertiesConfiguration config = PropertiesUtils.INSTANCE.getConfig();
 private static CloseableHttpClient client = null;

 public static String requestWithPost(String postUrl, JSONObject reqJson, Boolean https, Boolean proxy) {

  HttpResponse rsp = null;
  try {
   client = SSLClient.getHttpsClient(https);
  } catch (Exception e) {
   logger.error("獲取httpCliet失敗");
  }
  HttpPost post = new HttpPost(postUrl);

  if (proxy) {
   String proxyIP = config.getString("proxyIP");
   int proxyPort = Integer.parseInt(config.getString("proxyPort"));
   logger.info("使用代理發送請求：{}:{}", proxyIP, proxyPort);
   HttpHost proxyHost = new HttpHost(proxyIP, proxyPort);
   RequestConfig reqConfig = RequestConfig.custom().setProxy(proxyHost).build();
   post.setConfig(reqConfig);
  }
  StringEntity params = null;
  String rspStr = "";

  try {
   params = new StringEntity(reqJson.toString(), "utf-8");
   params.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
   params.setChunked(true);
   post.addHeader("content-type", "application/json");
   post.setEntity(params);
   rsp = client.execute(post);
   HttpEntity entity = rsp.getEntity();
   String rspString = EntityUtils.toString(entity, "utf-8");
   JSONObject rspJson = JSONObject.parseObject(rspString);
   logger.info("請求返回報文：{}", rspJson);
   rspStr = rspJson.toString();
  } catch (Exception e) {
   logger.info("外調異常：：{}", e.getMessage());
  } finally {
   client.getConnectionManager().shutdown();
  }
  return rspStr;
 } 
}

2. 創建https client

public class SSLClient {

 private static HttpClientBuilder builder;

 public static CloseableHttpClient getHttpsClient(Boolean https)
   throws KeyManagementException, NoSuchAlgorithmException {
  if (builder == null) {
   builder = HttpClientBuilder.create();
  }
  if (!https) {
   return builder.build();
  } else {
   X509TrustManager tm = new X509TrustManager() {

    @Override
    public X509Certificate[] getAcceptedIssuers() {
     return null;
    }

    @Override
    public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
     // TODO Auto-generated method stub

    }

    @Override
    public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
     // TODO Auto-generated method stub
    }
   };
   SSLContext ctx = SSLContext.getInstance("TLS");
   ctx.init(null, new TrustManager[] { tm }, null);
   SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
   builder.setSSLSocketFactory(ssf);
  }
  return builder.build();

 }
