SpringMVC template和HttpClient post提交

服务器的接口如果是springmvc客户端除了用springmvc提供的RestTemplate请求如下

public class RestClient {

private static Logger logger = Logger.getLogger(RestClient.class);

@SuppressWarnings({ rawtypes, unchecked })

public static Object post(String url, Map<string, object=""> message) {

Object result = null;

try {

RestTemplate rest = new RestTemplate();

MultiValueMap<string, object=""> param = new LinkedMultiValueMap();

for(Entry<string, object=""> entry : message.entrySet()) {

param.add(entry.getKey(), entry.getValue());

}

result = rest.postForObject(url, param, String.class);

} catch (Exception e) {

logger.error(发送消息发生异常+e);

}

return result;

}

}

import java.io.UnsupportedEncodingException;

import org.springframework.util.LinkedMultiValueMap;

import org.springframework.util.MultiValueMap;

import org.springframework.web.client.RestTemplate;

import test.ThreeDES;

public class TestPost {

public static void main(String[] args) {

//spring方式

RestTemplate rest = new RestTemplate();//创建org.springframework.web.client.RestTemplate

MultiValueMap<String,Object> param = new LinkedMultiValueMap<String,Object>();//创建参数Map  org.springframework.util.LinkedMultiValueMap

//map设值

param.add("id", "1");

param.add("carbonOrderNo", "M201702161055");

param.add("name", "王烟");

param.add("userTypes", "OTHER");

param.add("tel", "13020232323");

param.add("certificateNo", "99021023456");

param.add("money", "2");

param.add("donationWays", "CASHPAY");

String result = rest.postForObject("http://localhost:8080/trip/bD/send?", param, String.class);//postForObject   post方式

System.out.println(result);

}

}

还可以用httpclient发送请求如下:

package com.ckdh.web.test;

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.DefaultHttpClient;

public class DownloadResourcesTest {

public static void main(String[] args) {

String url = http://localhost:8080/xxx-web/xxx.mvc?apikey=1;

HttpClient client = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(url);

InputStream is = null;

InputStreamReader isr = null;

BufferedReader br = null;

try {

httpPost.addHeader(city, 010);

httpPost.addHeader(version, 2);

HttpEntity entity = new StringEntity(<infos><info hash="a0fd9704eb1432892cbc19742811b63" spid="88"> +

</info><info hash="e7b8894b8bc4d4eac22dffd85f28a68" spid="p1"></info></infos>);

httpPost.setEntity(entity);

HttpResponse response = client.execute(httpPost);

System.out.println(response.getStatusLine());

is = response.getEntity().getContent();

isr = new InputStreamReader(is, UTF-8);

br = new BufferedReader(isr);

StringBuffer buf = new StringBuffer();

String line;

while (null != (line = br.readLine())) {

buf.append(line).append();

}

System.out.println(buf.toString());

} catch (Exception e) {

e.printStackTrace();

}

}

}
