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;
  }


 
}
