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; } }

以上就是小编为大家带来的httpclient 请求http数据,json转map的实例全部内容了，希望大家多多支持~
