java使用HttpClient传输json格式的参数

最近的一个接口项目，传的参数要求是json，需要特殊处理一下。

重点是这两句话：

httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");
se.setContentType(CONTENT_TYPE_TEXT_JSON);这两句话的作用与jmeter的设置header信息类似

package com.base;

import java.io.UnsupportedEncodingException;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.impl.conn.PoolingClientConnectionManager;
import org.apache.http.util.EntityUtils;

        HttpPost httpPost = new HttpPost(url);
        httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");

        StringEntity se = new StringEntity(js);
        se.setContentType(CONTENT_TYPE_TEXT_JSON);

        httpPost.setEntity(se);

        CloseableHttpResponse response2 = null;

        response2 = client.execute(httpPost);
        HttpEntity entity2 = null;
        entity2 = response2.getEntity();
        String s2 = EntityUtils.toString(entity2, "UTF-8");
        System.out.println(s2);
      }
