一个简单的HttpClient POST 请求实例

package com.httpclientget;

import java.awt.List;

import java.util.ArrayList;

import org.apache.http.client.HttpClient;

import org.apache.http.client.entity.UrlEncodedFormEntity;

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

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

import org.apache.http.message.BasicNameValuePair;

import org.apache.http.util.EntityUtils;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.NameValuePair;

public class TestPost {

	public static void main(String[] args) {

		CreatHttpUrl creatUrl = new CreatHttpUrl();

		String urlStr = "https://openapi.youdao.com/api";

		String paramStr = creatUrl.createParam("good","en","zh-CHS");

		System.out.println(paramStr);

		new Post().start();

	}

}

class Post extends Thread

{

	HttpClient client = HttpClients.createDefault();

     @Override

    public void run() {

         HttpPost post = new HttpPost("https://openapi.youdao.com/api");

    	 try {

    		 //post要提交的参数

    		 ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();

    		 params.add(new BasicNameValuePair("q", "good"));

    		 params.add(new BasicNameValuePair("salt", "1496238482428"));

    		 params.add(new BasicNameValuePair("sign", "02E15CDAF871B698FE04EE32FD2CF155"));

    		 params.add(new BasicNameValuePair("from", "en"));

    		 params.add(new BasicNameValuePair("appKey", "7743eee7f7e11d75"));

    		 params.add(new BasicNameValuePair("to", "zh-CHS")); 

             //设置提交编码

             post.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

             //创建response接收返回值

             HttpResponse response = client.execute(post);

             HttpEntity entity = response.getEntity();

             String result = EntityUtils.toString(entity,"UTF-8");

             System.out.print(result);

		} catch (Exception e) {

		     e.printStackTrace();
