httpclient 请求http数据,json转map的实例

实例如下：

package com.idc.dataAudit.dataResource;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.GetMethod;

public class RequestHttpManage {
	public Map<Integer,String> RequesthttpInfo(String url) {
		String resultStr = null;
		Map<Integer,String> mapResult = new HashMap<Integer,String>();
  	try{
			HttpClient client = new HttpClient();
			HttpMethod method=new GetMethod(url);
			//使用POST方法
			//HttpMethod method = new PostMethod("http://java.sun.com");
			client.executeMethod(method); 

			//打印服务器返回的状态
			//System.out.println(method.getProtocolVersion());
			//System.out.println(method.getStatusLine().getStatusCode());
			//System.out.println(method.getStatusLine().getReasonPhrase());
			  // System.out.println(method.getStatusLine().toString());
			  // System.out.println(method.getStatusLine());
			//打印返回的信息
			  // System.out.println(method.getResponseBodyAsString()); 

			mapResult.put(method.getStatusLine().getStatusCode(), method.getResponseBodyAsString());
			//释放连接
			method.releaseConnection();
  	}catch(Exception e){
  		e.printStackTrace();
  	}
  	System.out.println(mapResult);
  	return mapResult;
  }
	public Map<String,List<String>> GetMapFromJson(String jsonStr){
  	Map<String,List<String>> mapResult = new HashMap<String,List<String>>();
  	try{

  		 JSONObject result = JSONObject.fromObject(jsonStr);//转换为JSONObject

       JSONArray nameList = result.getJSONArray("result");//获取JSONArray
       int length = nameList.size();
       for(int i=0;i<length;i++){
      	 JSONObject tempObject = nameList.getJSONObject(i);

      	 Iterator iter = tempObject.keys();
      	 String key = (String)iter.next();

      	 String keyId = tempObject .getString(key);

      	 List<String> objList = new ArrayList<String>();
      	 for (; iter.hasNext();) {
      	    String keyLocal = (String)iter.next();
      	  //  System.out.println(key+"="+tempObject .getString(keyLocal));
      	    objList.add(tempObject .getString(keyLocal));
      	 }
      	 mapResult.put(keyId, objList);
       }
  	}catch(Exception e){
  		e.printStackTrace();
  	}
  	System.out.println(mapResult);
  	return mapResult;
  }

}
