如何使用HttpClient发送java对象到服务器

这篇文章主要介绍了如何使用HttpClient发送java对象到服务器,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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

publicclassFulFillMentimplementsBaseModel{
/**
*shopify内部订单物理位置ID
*/
privateLonglocation_id;
/**
*运单号
*/
privateStringtracking_number;
/**
*快递公司
*/
privateStringtracking_company;
/**
*shopify平台内部商品id
*/
privateListline_items;
publicLonggetLocation_id(){
returnlocation_id;
}
publicvoidsetLocation_id(Longlocation_id){
this.location_id=location_id;
}
publicStringgetTracking_number(){
returntracking_number;
}

publicvoidsetTracking_number(Stringtracking_number){
this.tracking_number=tracking_number;
}

publicStringgetTracking_company(){
returntracking_company;
}

publicvoidsetTracking_company(Stringtracking_company){
this.tracking_company=tracking_company;
}
publicListgetLine_items(){
returnline_items;
}
publicvoidsetLine_items(Listline_items){
this.line_items=line_items;
}
}

三、这里封装一个上传到服务器的Utils工具类

packagecom.glbpay.ivs.common.util.https;
importcom.alibaba.fastjson.JSON;
importorg.apache.http.HttpEntity;

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


publicclassNewHttpClient{
publicstaticStringdoPost(Stringurl,Objectmyclass){
CloseableHttpClienthttpClient=HttpClientBuilder.create().build();
HttpPostposturl=newHttpPost(url);
Stringresult=null;
StringjsonSting=JSON.toJSONString(myclass);
StringEntityentity=newStringEntity(jsonSting,"UTF-8");
posturl.setEntity(entity);
posturl.setHeader("Content-Type","application/json;charset=utf8");
//响应模型
CloseableHttpResponseresponse=null;
try{
//由客户端执行(发送)Post请求
+6response=httpClient.execute(posturl);
//从响应模型中获取响应实体
HttpEntityresponseEntity=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));
returnEntityUtils.toString(responseEntity);
}
}catch(ClientProtocolExceptione){
e.printStackTrace();
}catch(Exceptione){
e.printStackTrace();
}finally{
try{
//释放资源
if(httpClient!=null){
httpClient.close();
}
if(response!=null){
response.close();
}
}catch(IOExceptione){
e.printStackTrace();
}
}
returnnull;
}
publicstaticStringdourl(Stringurl,Objectclzz){
try{
StringjsonString=JSON.toJSONString(clzz);
URLurl1=newURL(url);
HttpURLConnectionconn=(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
OutputStreamstream=conn.getOutputStream();
stream.write(bytes);
stream.flush();
stream.close();
intresultCode=conn.getResponseCode();
if(conn.getResponseCode()==200){
InputStreaminputStream=conn.getInputStream();
byte[]bytes1=newbyte[inputStream.available()];
inputStream.read(bytes1);
//转字符串
Strings=newString(bytes);
System.out.println(s);
returns;
}else{
//获取响应内容
intcode=conn.getResponseCode();
StringresponseMessage=conn.getResponseMessage();
System.out.println(code);
Strings=String.valueOf(code);
return"响应状态码是:"+s+"响应内容是：======="+responseMessage;
}
}catch(MalformedURLExceptione){
e.printStackTrace();
}catch(IOExceptione){
e.printStackTrace();
}
returnnull;
}

}

开始调用

FulFillMentModelfulFillMentModel=newFulFillMentModel();
FulFillMentfulfillment=newFulFillMent();
fulfillment.setLocation_id(order.getLocationId());
fulfillment.setTracking_number(order.getTrackingNo());
fulfillment.setTracking_company(order.getChannelCode());
fulfillment.setLine_items(lineItemList);
fulFillMentModel.setFulfillment(fulfillment);
Stringurl=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));
Strings=NewHttpClient.doPost(url,fulFillMentModel);
logger.info("shopify平台返回数据:{}",JsonUtils.bean2json(s));
