最近的一個介面專案，傳的引數要求是json，需要特殊處理一下。

重點是這兩句話：

httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");
se.setContentType(CONTENT_TYPE_TEXT_JSON);這兩句話的作用與jmeter的設定header資訊類似
package com.base;

import org.apache.http.entity.StringEntity;

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