JAVA携带参数(带有请求参数,请求头参数)直接发送POST请求
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.3.3</version> </dependency>
package com.test; import org.apache.http.HttpEntity; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; import java.util.ArrayList; import java.util.List; public class Test { public static void main(String[] args) { sendPost(); } public static void sendPost(){ String value="12222"; //创建post请求对象 HttpPost post = new HttpPost("http://localhost:8080/test"); try { //创建参数集合 List<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>(); //添加参数 list.add(new BasicNameValuePair("key", value)); list.add(new BasicNameValuePair("releaseDate","2020-07-14 09:55:20")); //把参数放入请求对象,,post发送的参数list,指定格式 post.setEntity(new UrlEncodedFormEntity(list, "UTF-8")); //添加请求头参数 post.addHeader("timestamp","1594695607545"); CloseableHttpClient client = HttpClients.createDefault(); //启动执行请求,并获得返回值 CloseableHttpResponse response = client.execute(post); //得到返回的entity对象 HttpEntity entity = response.getEntity(); //把实体对象转换为string String result = EntityUtils.toString(entity, "UTF-8"); //返回内容 System.out.println(result); } catch (Exception e1) { e1.printStackTrace(); } } }
下面是把方法进行了封装
/** * * 发送请求 * @param url 发送的url * @param headerMap 请求头参数集合 key参数名 value为参数值 * @param bodyMap 请求参数集合 key参数名 value为参数值 */ public static String sendPost(String url, Map<String,String> headerMap,Map<String,String> bodyMap){ //创建post请求对象 HttpPost post = new HttpPost(url); try { //创建参数集合 List<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>(); //添加参数 if (bodyMap!=null){ for (String str:bodyMap.keySet() ) { list.add(new BasicNameValuePair(str, bodyMap.get(str))); } } //把参数放入请求对象,,post发送的参数list,指定格式 post.setEntity(new UrlEncodedFormEntity(list, "UTF-8")); if (headerMap!=null){ for (String str:headerMap.keySet() ) { post.addHeader(str,headerMap.get(str)); } } CloseableHttpClient client = HttpClients.createDefault(); //启动执行请求,并获得返回值 CloseableHttpResponse response = client.execute(post); //得到返回的entity对象 HttpEntity entity = response.getEntity(); //把实体对象转换为string String result = EntityUtils.toString(entity, "UTF-8"); //返回内容 return result; } catch (Exception e1) { e1.printStackTrace(); return ""; } }
