使用HttpClient 添加header自定义参数

package com.cmcc.andedu.util;

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;
import org.apache.http.util.EntityUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


public class HttpClientTools {


    private static Logger log = LoggerFactory.getLogger(HttpClientTools.class);


    /**
     * @Description post请求，添加hearder
     * @param path path绝对路径
     * @param body JSON格式字符串
     * @return
     **/
    public String doPost(String path, String token, String body){
        String result = "";
        try {

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(path);
            //添加header参数
            httpPost.addHeader("Authorization","Bearer "+token);
            httpPost.addHeader("Content-Type", "application/json;charset=UTF-8");
            
            //这里需要指定请求参数的编码，否则默认是ISO_8859_1
            StringEntity stringEntity = new StringEntity(body,"UTF-8");
            stringEntity.setContentType("application/json");
            httpPost.setEntity(stringEntity);

            HttpResponse response = httpclient.execute(httpPost);
            if(response != null){
                HttpEntity resEntity = response.getEntity();
                if(resEntity != null){
                    result = EntityUtils.toString(resEntity,"UTF-8");
                }
            }
        }catch (Exception e){
            log.error("请求异常:"+path);
            e.printStackTrace();

        }
        return result;
    }


}

不得不说，httpclient 还是很强大的。
