一、首先导入apache依赖的pom文件包
org.apache.httpcomponents httpclient
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 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 getLine_items() {
return line_items;
}
public void setLine_items(List 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));以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持创新互联。
