vs2017网站开发组件线上平台推广方案

一、引入依赖包

• 引入相关依赖包

   <!--lombok用于简化实体类开发--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--fastjson依赖--><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>2.0.32</version></dependency><!--httpclient依赖--><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.2</version></dependency>
  

二、HttpClient方式实现的https请求工具类

• https工具类代码

  package com.xz.https;import com.alibaba.fastjson.JSONObject;
  import lombok.extern.slf4j.Slf4j;
  import org.apache.http.HttpEntity;
  import org.apache.http.ParseException;
  import org.apache.http.client.methods.CloseableHttpResponse;
  import org.apache.http.client.methods.HttpPost;
  import org.apache.http.config.Registry;
  import org.apache.http.config.RegistryBuilder;
  import org.apache.http.conn.socket.ConnectionSocketFactory;
  import org.apache.http.conn.socket.PlainConnectionSocketFactory;
  import org.apache.http.conn.ssl.NoopHostnameVerifier;
  import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
  import org.apache.http.entity.StringEntity;
  import org.apache.http.impl.client.CloseableHttpClient;
  import org.apache.http.impl.client.HttpClients;
  import org.apache.http.impl.conn.PoolingHttpClientConnectionManager;
  import org.apache.http.util.EntityUtils;
  import org.springframework.core.io.ClassPathResource;import javax.net.ssl.SSLContext;
  import javax.net.ssl.TrustManager;
  import javax.net.ssl.TrustManagerFactory;
  import javax.net.ssl.X509TrustManager;
  import java.io.IOException;
  import java.security.KeyManagementException;
  import java.security.KeyStore;
  import java.security.KeyStoreException;
  import java.security.NoSuchAlgorithmException;
  import java.security.cert.Certificate;
  import java.security.cert.CertificateException;
  import java.security.cert.CertificateFactory;
  import java.security.cert.X509Certificate;/*** @Description HttpClient方式的 https工具类* @author xz*/
  @Slf4j
  public class HttpsUtil {public static String post(String url, JSONObject content) throws Exception {String returnInfo = "";CloseableHttpResponse response = null;//getTrust():进行证书验证;allTrust:绕过证书验证PoolingHttpClientConnectionManager connectionManager = allTrust();try (CloseableHttpClient client = HttpClients.custom().setConnectionManager(connectionManager).build()) {HttpPost post = new HttpPost(url);//指定报文头post.setHeader("Context-Type", "application/json;charset=UTF-8");//设置entityStringEntity entity = new StringEntity(JSONObject.toJSONString(content), "UTF-8");entity.setContentType("application/json");post.setEntity(entity);//发送请求response = client.execute(post);log.info("response->:{}", response);HttpEntity resEntity = response.getEntity();if (resEntity != null) {returnInfo = EntityUtils.toString(resEntity, "UTF-8");}EntityUtils.consume(resEntity);response.close();return returnInfo;} catch (IOException | ParseException e) {log.info("errorLogs->:{}", e);return returnInfo;}}/*** 绕过验证* @author xz*/public static PoolingHttpClientConnectionManager allTrust() {SSLContext sslContext = null;PoolingHttpClientConnectionManager connectionManager = null;try {sslContext = SSLContext.getInstance("TLSv1.2");X509TrustManager trustManager = new X509TrustManager() {@Overridepublic void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];}};sslContext.init(null, new TrustManager[]{trustManager}, null);//设置http和https对应处理socket链接工厂的对象Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create().register("http", PlainConnectionSocketFactory.INSTANCE).register("https", new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE)).build();connectionManager = new PoolingHttpClientConnectionManager(registry);} catch (NoSuchAlgorithmException | KeyManagementException e) {log.info("errorLogs->:{}", e);}return connectionManager;}/*** 进行证书验证* @author xz*/public static PoolingHttpClientConnectionManager getTrust() {PoolingHttpClientConnectionManager connectionManager = null;try {CertificateFactory certificateFactory = CertificateFactory.getInstance("x.509");//证书路径ClassPathResource classPathResource = new ClassPathResource("xxxx.pem");Certificate certificate = certificateFactory.generateCertificate(classPathResource.getInputStream());//creat TrustStoreKeyStore keyStore = KeyStore.getInstance("JKS");keyStore.load(null ,null);//Add certificatekeyStore.setCertificateEntry("key",certificate);TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());trustManagerFactory.init(keyStore);//creatSSlContextSSLContext sslContext = SSLContext.getInstance("TLSv1.2");sslContext.init(null,trustManagerFactory.getTrustManagers(),null);//设置http和https对应处理socket链接工厂的对象Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create().register("http", PlainConnectionSocketFactory.INSTANCE).register("https", new SSLConnectionSocketFactory(sslContext)).build();connectionManager = new PoolingHttpClientConnectionManager(registry);} catch (CertificateException | IOException | KeyStoreException | NoSuchAlgorithmException | KeyManagementException e) {log.info("errorLogs->:{}", e);}return connectionManager;}}
  

三、测试类

• 测试代码

  package com.xz.https;import com.alibaba.fastjson.JSONObject;/*** @author: xz* @since: 2024/1/11 22:17* @description:*/
  public class HttpsUtilsTest {public static void main(String[] args) throws Exception {String url="https://xxx.com.cn:5678/gateway/user/service/getxxxx";UserReq userReq = new UserReq ();userReq .setName("张三");JSONObject parse = (JSONObject)JSONObject.parse(JSONObject.toJSONString(userReq));String result = HttpsUtil.post(url, parse);System.out.println("HttpClient---https请求："+result);}
  }
  

• 测试输出结果
