java通过okhttp方式实现https请求的工具类（绕过证书验证）

一、引入依赖包

• 引入相关依赖包

  <!--okhttp依赖包-->
  <dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>okhttp</artifactId>
      <version>4.10.0</version>
  </dependency>
  <!--lombok用于简化实体类开发-->
  <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <optional>true</optional>
  </dependency>
  

二、okhttp方式实现的https请求工具类

2.1、跳过证书配置类

• 跳过证书配置类代码

  package com.xz.https;
  import okhttp3.OkHttpClient;
  
  import javax.net.ssl.SSLContext;
  import javax.net.ssl.SSLSocketFactory;
  import javax.net.ssl.TrustManager;
  import javax.net.ssl.X509TrustManager;
  import java.security.KeyManagementException;
  import java.security.NoSuchAlgorithmException;
  
  /**
   * @Description 跳过证书配置类
   * @author xz
   */
  public class OKHttpClientBuilder {
      public static OkHttpClient.Builder buildOKHttpClient() {
          try {
              TrustManager[] trustAllCerts = buildTrustManagers();
              final SSLContext sslContext = SSLContext.getInstance("SSL");
              sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
  
              final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
              OkHttpClient.Builder builder = new OkHttpClient.Builder();
              builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
              builder.hostnameVerifier((hostname, session) -> true);
              return builder;
          } catch (NoSuchAlgorithmException | KeyManagementException e) {
              e.printStackTrace();
              return new OkHttpClient.Builder();
          }
      }
  
      private static TrustManager[] buildTrustManagers() {
          return new TrustManager[]{
                  new X509TrustManager() {
                      @Override
                      public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {
                      }
  
                      @Override
                      public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {
                      }
  
                      @Override
                      public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                          return new java.security.cert.X509Certificate[]{};
                      }
                  }
          };
      }
  }
  

2.2、okhttp方式的 https工具类

三、测试类

• 测试代码

  package com.xz.https;
  
  import com.alibaba.fastjson.JSONObject;
  
  /**
   * @author: xz
   * @since: 2024/1/11 22:07
   * @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");
          String result = OkhttpsUtils.doPost(url, JSONObject.toJSONString(accessTokenReq), null);
          System.out.println("Okhttps---https请求："+result);
      }
  }
