使用HttpClient怎么发送java对象到服务器,很多新手对此不是很清楚,为了帮助大家解决这个难题,下面小编将为大家详细讲解,有这方面需求的人可以来学习下,希望你能有所收获。
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; }}
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));
