使用HttpClient发送java对象到服务器

    一、首先导入apache依赖的pom文件包

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
</dependency>

二、创建JavaBean实体类对象

public class FulFillMent implements BaseModel {
    /**
     * shopify内部订单物理位置ID
     */
    private Long location_id;
    /**
     * 运单号
     */
    private String tracking_number;
    /**
     * 快递公司
     */
    private String tracking_company;
    /**
     * shopify平台内部商品id
     */
    private List<LineItem> line_items;
    public Long getLocation_id() {
        return location_id;
    }
    public void setLocation_id(Long location_id) {
        this.location_id = location_id;
    }
    public String getTracking_number() {
        return tracking_number;
    }

    public void setTracking_number(String tracking_number) {
        this.tracking_number = tracking_number;
    }

    public String getTracking_company() {
        return tracking_company;
    }

    public void setTracking_company(String tracking_company) {
        this.tracking_company = tracking_company;
    }
    public List<LineItem> getLine_items() {
        return line_items;
    }
    public void setLine_items(List<LineItem> line_items) {
        this.line_items = line_items;
    }
}

三、这里封装一个上传到服务器的Utils工具类

package com.glbpay.ivs.common.util.https;
import com.alibaba.fastjson.JSON;
import org.apache.http.HttpEntity;

import java.io.InputStream;
import java.io.OutputStream;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;


public class NewHttpClient {
    public static String doPost(String url, Object myclass) {
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost posturl = new HttpPost(url);
        String result = null;
        String jsonSting = JSON.toJSONString(myclass);
        StringEntity entity = new StringEntity(jsonSting, "UTF-8");
        posturl.setEntity(entity);
        posturl.setHeader("Content-Type", "application/json;charset=utf8");
        // 响应模型
        CloseableHttpResponse response = null;
        try {
            // 由客户端执行(发送)Post请求
+6            response = httpClient.execute(posturl);
            // 从响应模型中获取响应实体
            HttpEntity responseEntity = response.getEntity();

            System.out.println("响应状态为:" + response.getStatusLine());
            if (responseEntity != null) {
                System.out.println("响应内容长度为:" + responseEntity.getContentLength());
                System.out.println("响应内容为:" + EntityUtils.toString(responseEntity));
                return EntityUtils.toString(responseEntity);
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                // 释放资源
                if (httpClient != null) {
                    httpClient.close();
                }
                if (response != null) {
                    response.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
      return null;
    }
    public static String dourl(String url,Object clzz){
        try {
            String jsonString = JSON.toJSONString(clzz);
            URL url1 = new URL(url);
            HttpURLConnection conn = (HttpURLConnection) url1.openConnection();
            //设置允许输出
            conn.setDoOutput(true);
            //设置允许输入
            conn.setDoInput(true);
            //设置不用缓存
            conn.setUseCaches(false);
            conn.setRequestMethod("POST");

            //设置传递方式
            conn.setRequestProperty("contentType", "application/json");
            // 设置维持长连接
            conn.setRequestProperty("Connection", "Keep-Alive");
            // 设置文件字符集:
            conn.setRequestProperty("Charset", "UTF-8");
            //开始请求
            byte[] bytes = jsonString.toString().getBytes();
            //写流
            OutputStream stream = conn.getOutputStream();
            stream.write(bytes);
            stream.flush();
            stream.close();
            int resultCode=conn.getResponseCode();
              if(conn.getResponseCode()==200){
              InputStream inputStream = conn.getInputStream();
              byte[] bytes1 = new byte[inputStream.available()];
              inputStream.read(bytes1);
              //转字符串
              String s = new String(bytes);
              System.out.println(s);
                  return s;
          }else {
                  //获取响应内容
                  int code = conn.getResponseCode();
                  String responseMessage = conn.getResponseMessage();
                  System.out.println(code);
                  String s = String.valueOf(code);
                  return "响应状态码是:"+s+"响应内容是：======="+responseMessage;
              }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
                  return null;
    }

}

三、开始调用

FulFillMentModel fulFillMentModel = new FulFillMentModel();
FulFillMent fulfillment = new FulFillMent();
fulfillment.setLocation_id(order.getLocationId());
fulfillment.setTracking_number(order.getTrackingNo());
fulfillment.setTracking_company(order.getChannelCode());
fulfillment.setLine_items(lineItemList);
fulFillMentModel.setFulfillment(fulfillment);
String url = String.format("https://%s:%s@stuushop-com.myshopify.com/admin/api/2019-07/orders/%s/fulfillments.json", settingModel.getAppKey(), settingModel.getPassword(), order.getLastOrderId());
logger.info("shopify平台请求地址：{}，请求数据:{}", url, JsonUtils.bean2json(fulFillMentModel));
String s = NewHttpClient.doPost(url,fulFillMentModel);
logger.info("shopify平台返回数据:{}", JsonUtils.bean2json(s));
