這篇文章主要介紹了如何使用HttpClient發(fā)送java對(duì)象到服務(wù)器,文中通過示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下

一、首先導(dǎo)入apache依賴的pom文件包

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

二、創(chuàng)建JavaBean實(shí)體類對(duì)象

public class FulFillMent implements BaseModel {
  /**
   * shopify內(nèi)部訂單物理位置ID
   */
  private Long location_id;
  /**
   * 運(yùn)單號(hào)
   */
  private String tracking_number;
  /**
   * 快遞公司
   */
  private String tracking_company;
  /**
   * shopify平臺(tái)內(nèi)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、這里封裝一個(gè)上傳到服務(wù)器的Utils工具類

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");
    // 響應(yīng)模型
    CloseableHttpResponse response = null;
    try {
      // 由客戶端執(zhí)行(發(fā)送)Post請(qǐng)求
+6      response = httpClient.execute(posturl);
      // 從響應(yīng)模型中獲取響應(yīng)實(shí)體
      HttpEntity responseEntity = response.getEntity();

      System.out.println("響應(yīng)狀態(tài)為:" + response.getStatusLine());
      if (responseEntity != null) {
        System.out.println("響應(yīng)內(nèi)容長(zhǎng)度為:" + responseEntity.getContentLength());
        System.out.println("響應(yīng)內(nèi)容為:" + EntityUtils.toString(responseEntity));
        return EntityUtils.toString(responseEntity);
      }
    } catch (ClientProtocolException e) {
      e.printStackTrace();
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      try {
        // 釋放資源
        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();
      //設(shè)置允許輸出
      conn.setDoOutput(true);
      //設(shè)置允許輸入
      conn.setDoInput(true);
      //設(shè)置不用緩存
      conn.setUseCaches(false);
      conn.setRequestMethod("POST");

      //設(shè)置傳遞方式
      conn.setRequestProperty("contentType", "application/json");
      // 設(shè)置維持長(zhǎng)連接
      conn.setRequestProperty("Connection", "Keep-Alive");
      // 設(shè)置文件字符集:
      conn.setRequestProperty("Charset", "UTF-8");
      //開始請(qǐng)求
      byte[] bytes = jsonString.toString().getBytes();
      //寫流
      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);
       //轉(zhuǎn)字符串
       String s = new String(bytes);
       System.out.println(s);
         return s;
     }else {
         //獲取響應(yīng)內(nèi)容
         int code = conn.getResponseCode();
         String responseMessage = conn.getResponseMessage();
         System.out.println(code);
         String s = String.valueOf(code);
         return "響應(yīng)狀態(tài)碼是:"+s+"響應(yīng)內(nèi)容是：======="+responseMessage;
       }
    } catch (MalformedURLException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
         return null;
  }

}

開始調(diào)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平臺(tái)請(qǐng)求地址：{}，請(qǐng)求數(shù)據(jù):{}", url, JsonUtils.bean2json(fulFillMentModel));
String s = NewHttpClient.doPost(url,fulFillMentModel);
logger.info("shopify平臺(tái)返回?cái)?shù)據(jù):{}", JsonUtils.bean2json(s));

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
