SpringBoot 配置 okhttp3的操作

1、Maven

<dependency>
 <groupId>com.squareup.okhttp3</groupId>
 <artifactId>okhttp</artifactId>
 <version>3.10.0</version>
</dependency>

2、配置

ok.http.connect-timeout=30
ok.http.read-timeout=30
ok.http.write-timeout=30
# 连接池中整体的空闲连接的最大数量
ok.http.max-idle-connections=200
# 连接空闲时间最多为 300 秒
ok.http.keep-alive-duration=300

3、configuration 类

import okhttp3.ConnectionPool;
import okhttp3.OkHttpClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.net.ssl.*;
import java.security.*;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;
/**

 */
@Configuration
public class OkHttpConfiguration {
 @Value("${ok.http.connect-timeout}")
 private Integer connectTimeout;
 @Value("${ok.http.read-timeout}")
 private Integer readTimeout;
 @Value("${ok.http.write-timeout}")
 private Integer writeTimeout;
 @Value("${ok.http.max-idle-connections}")
 private Integer maxIdleConnections;
 @Value("${ok.http.keep-alive-duration}")
 private Long keepAliveDuration;
 @Bean
 public OkHttpClient okHttpClient() {
  return new OkHttpClient.Builder()
    .sslSocketFactory(sslSocketFactory(), x509TrustManager())
    // 是否开启缓存
    .retryOnConnectionFailure(false)
    .connectionPool(pool())
    .connectTimeout(connectTimeout, TimeUnit.SECONDS)
    .readTimeout(readTimeout, TimeUnit.SECONDS)
    .writeTimeout(writeTimeout,TimeUnit.SECONDS)
   	.hostnameVerifier((hostname, session) -> true)
   	// 设置代理
//   	.proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 8888)))
    // 拦截器
//    .addInterceptor()
    .build();
 }
 @Bean
 public X509TrustManager x509TrustManager() {
  return new X509TrustManager() {
   @Override
   public void checkClientTrusted(X509Certificate[] chain, String authType)
     throws CertificateException {
   }
   @Override
   public void checkServerTrusted(X509Certificate[] chain, String authType)
     throws CertificateException {
   }
   @Override
   public X509Certificate[] getAcceptedIssuers() {
    return new X509Certificate[0];
   }
  };
 }
 @Bean
 public SSLSocketFactory sslSocketFactory() {
  try {
   // 信任任何链接
   SSLContext sslContext = SSLContext.getInstance("TLS");
   sslContext.init(null, new TrustManager[]{x509TrustManager()}, new SecureRandom());
   return sslContext.getSocketFactory();
  } catch (NoSuchAlgorithmException | KeyManagementException e) {
   e.printStackTrace();
  }
  return null;
 }
 @Bean
 public ConnectionPool pool() {
  return new ConnectionPool(maxIdleConnections, keepAliveDuration, TimeUnit.SECONDS);
 }
}

4、until类

import lombok.extern.slf4j.Slf4j;
import okhttp3.*;
import org.apache.commons.lang3.exception.ExceptionUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.Map;
/**
 * @author Answer.AI.L
 * @date 2019-04-09
 */
@Slf4j
@Component
public class OkHttpCli {
 private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
 private static final MediaType XML = MediaType.parse("application/xml; charset=utf-8");
 @Autowired
 private OkHttpClient okHttpClient;
 /**
  * get 请求
  * @param url  请求url地址
  * @return string
  * */
 public String doGet(String url) {
  return doGet(url, null, null);
 }
 /**
  * get 请求
  * @param url  请求url地址
  * @param params 请求参数 map
  * @return string
  * */
 public String doGet(String url, Map<String, String> params) {
  return doGet(url, params, null);
 }
 /**
  * get 请求

  * @param headers 请求头字段 {k1, v1 k2, v2, ...}
  * @return string
  * */
 public String doGet(String url, String[] headers) {
  return doGet(url, null, headers);
 }
 /**
  * get 请求
  * @param url  请求url地址
  * @param params 请求参数 map
  * @param headers 请求头字段 {k1, v1 k2, v2, ...}
  * @return string
  * */
 public String doGet(String url, Map<String, String> params, String[] headers) {
  StringBuilder sb = new StringBuilder(url);
  if (params != null && params.keySet().size() > 0) {
   boolean firstFlag = true;
   for (String key : params.keySet()) {
    if (firstFlag) {
     sb.append("?").append(key).append("=").append(params.get(key));
     firstFlag = false;
    } else {
     sb.append("&").append(key).append("=").append(params.get(key));
    }
   }
  }
  Request.Builder builder = new Request.Builder();
  if (headers != null && headers.length > 0) {
   if (headers.length % 2 == 0) {
    for (int i = 0; i < headers.length; i = i + 2) {
     builder.addHeader(headers[i], headers[i + 1]);
    }
   } else {
    log.warn("headers's length[{}] is error.", headers.length);
   }
  }
  Request request = builder.url(sb.toString()).build();
  log.info("do get request and url[{}]", sb.toString());
  return execute(request);
 }
 /**
  * post 请求
  * @param url  请求url地址
  * @param params 请求参数 map
  * @return string
  */
 public String doPost(String url, Map<String, String> params) {
  FormBody.Builder builder = new FormBody.Builder();
  if (params != null && params.keySet().size() > 0) {
   for (String key : params.keySet()) {
    builder.add(key, params.get(key));
   }
  }
  Request request = new Request.Builder().url(url).post(builder.build()).build();
  log.info("do post request and url[{}]", url);
  return execute(request);
 }
 /**
  * post 请求, 请求数据为 json 的字符串
  * @param url  请求url地址
  * @param json  请求数据, json 字符串
  * @return string
  */
 public String doPostJson(String url, String json) {
  log.info("do post request and url[{}]", url);
  return exectePost(url, json, JSON);
 }
 /**
  * post 请求, 请求数据为 xml 的字符串
  * @param url  请求url地址
  * @param xml  请求数据, xml 字符串
  * @return string
  */
 public String doPostXml(String url, String xml) {
  log.info("do post request and url[{}]", url);
  return exectePost(url, xml, XML);
 }
 private String exectePost(String url, String data, MediaType contentType) {
  RequestBody requestBody = RequestBody.create(contentType, data);
  Request request = new Request.Builder().url(url).post(requestBody).build();
  return execute(request);
 }
 private String execute(Request request) {
  Response response = null;
  try {
   response = okHttpClient.newCall(request).execute();
   if (response.isSuccessful()) {
    return response.body().string();
   }
  } catch (Exception e) {
   log.error(ExceptionUtils.getStackTrace(e));
  } finally {
   if (response != null) {
    response.close();
   }
  }
  return "";
 }
}

5、使用示例

@RestController
public class AnswerController {
 @Autowired
 private OkHttpCli okHttpCli;
 
 
 @RequestMapping(value = "show", method = RequestMethod.GET)
 public String show() {
  String url = "https://www.baidu.com/";
 String message = okHttpCli.doGet(url);
  return message;
 }
 
}

6、ssl使用（待验证）

@Bean
public SSLSocketFactory sslSocketFactory() {
 String certPath = "";
 String caPath = "";
 String certPwd = "";
 String caPwd = "";
 try {
  ClassPathResource selfcertPath = new ClassPathResource(certPath);
  ClassPathResource trustcaPath = new ClassPathResource(caPath);
  KeyStore selfCert = KeyStore.getInstance("pkcs12");
  selfCert.load(selfcertPath.getInputStream(), certPwd.toCharArray());
  KeyManagerFactory kmf = KeyManagerFactory.getInstance("sunx509");
  kmf.init(selfCert, certPwd.toCharArray());
  KeyStore caCert = KeyStore.getInstance("jks");
  caCert.load(trustcaPath.getInputStream(), caPwd.toCharArray());
  TrustManagerFactory tmf = TrustManagerFactory.getInstance("sunx509");
  tmf.init(caCert);
  SSLContext sslContext = SSLContext.getInstance("TLS");
  sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
  return sslContext.getSocketFactory();
 } catch (Exception e) {
  e.printStackTrace();
 }
 return null;
}
