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() {@Overridepublic void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {}@Overridepublic void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {}@Overridepublic java.security.cert.X509Certificate[] getAcceptedIssuers() {return new java.security.cert.X509Certificate[]{};}}};}
  }
  

2.2、okhttp方式的 https工具类

• okhttp方式的 https工具类代码

  package com.xz.https;import lombok.extern.slf4j.Slf4j;
  import okhttp3.*;import java.io.IOException;
  import java.net.MalformedURLException;
  import java.net.URL;
  import java.util.Map;
  import java.util.concurrent.TimeUnit;/*** @Description okhttp方式的 https工具类* @author xz*/
  @Slf4j
  public class OkhttpsUtils {/*** 获取客户端链接*/private static OkHttpClient getClient() {OkHttpClient okHttpClient = OKHttpClientBuilder.buildOKHttpClient().connectTimeout(5000, TimeUnit.SECONDS).readTimeout(20000, TimeUnit.SECONDS).writeTimeout(20000, TimeUnit.SECONDS).build();return okHttpClient;}private static Request getRequest(String url, Map<String,String> header) throws MalformedURLException {Request.Builder builder = getBuilder(header);URL uri = new URL(url);return builder.url(uri).build();}private static Request.Builder getBuilder(Map<String,String> header) {Request.Builder builder = new Request.Builder();builder.addHeader("accept", "application/json").addHeader("connection", "Keep-Alive").addHeader("Content-Type", "application/json;charset=UTF-8");if(header != null && header.entrySet().size()>0){for(Map.Entry<String,String>  entry:header.entrySet()){builder.addHeader(entry.getKey(),entry.getValue());}}return builder;}/*** doGet请求*/public static String doGet(String url, String param, Map<String,String> header) {if (param != null) {url = url + "?" + param;}String result = null;try {OkHttpClient okHttpClient = getClient();Request request = getRequest(url,header);Response response = okHttpClient.newCall(request).execute();if (response.isSuccessful()) {ResponseBody body = response.body();if (body != null) {result = body.string();} else {throw new IOException("response body is null");}} else {response.close();}} catch (IOException e) {log.error("GET请求异常,url = {}", url, e);}return result;}/*** doPost请求*/public static String doPost(String url, String param,Map<String,String> header) {OkHttpClient okHttpClient = getClient();Request.Builder builder = getBuilder(header);String result = null;try {RequestBody requestBody = RequestBody.create(param.getBytes("UTF-8"),MediaType.parse(org.springframework.http.MediaType.APPLICATION_JSON_UTF8_VALUE));builder.post(requestBody);Request request = builder.url(url).build();Response response = okHttpClient.newCall(request).execute();if (response.isSuccessful()) {ResponseBody body = response.body();if (body != null) {result = body.string();} else {throw new IOException("response body is null");}} else {response.close();}} catch (Exception e) {log.error("POST请求异常,url = {}", url, e);}return result;}/*** doDelete请求*/public static String doDelete(String url, String param,Map<String,String> header) {OkHttpClient okHttpClient = getClient();Request.Builder builder = getBuilder(header);String result = null;try {if (param != null) {RequestBody requestBody = RequestBody.create(param.getBytes("UTF-8"),MediaType.parse(org.springframework.http.MediaType.APPLICATION_JSON_UTF8_VALUE));builder.delete(requestBody);} else {builder.delete();}Request request = builder.url(url).build();Response response = okHttpClient.newCall(request).execute();if (response.isSuccessful()) {ResponseBody body = response.body();if (body != null) {result = body.string();} else {throw new IOException("response body is null");}} else {response.close();}} catch (Exception e) {log.error("DELETE请求异常,url = {}", url, e);}return result;}/*** doPut请求*/public static String doPut(String url, String param,Map<String,String> header) {OkHttpClient okHttpClient = getClient();Request.Builder builder = getBuilder(header);String result = null;try {RequestBody requestBody = RequestBody.create(param.getBytes("UTF-8"),MediaType.parse(org.springframework.http.MediaType.APPLICATION_JSON_UTF8_VALUE));builder.put(requestBody);Request request = builder.url(url).build();Response response = okHttpClient.newCall(request).execute();if (response.isSuccessful()) {ResponseBody body = response.body();if (body != null) {result = body.string();} else {throw new IOException("response body is null");}} else {response.close();}} catch (Exception e) {log.error("PUT请求异常,url = {}", url, e);}return result;}}

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);}
  }
  

• 测试输出结果
