httpclient 请求http数据,json转map的实例
实例如下：
packagecom.idc.dataAudit.dataResource;
importjava.util.ArrayList;
importjava.util.HashMap;
importjava.util.Iterator;
importjava.util.List;
importjava.util.Map;
importnet.sf.json.JSONArray;
importnet.sf.json.JSONObject;
importorg.apache.commons.httpclient.HttpClient;
importorg.apache.commons.httpclient.HttpMethod;
importorg.apache.commons.httpclient.methods.GetMethod;
publicclassRequestHttpManage{
publicMap<Integer,String>RequesthttpInfo(Stringurl){
StringresultStr=null;
Map<Integer,String>mapResult=newHashMap<Integer,String>();
try{
HttpClientclient=newHttpClient();
HttpMethodmethod=newGetMethod(url);
//使用POST方法
//HttpMethodmethod=newPostMethod("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(Exceptione){
e.printStackTrace();
}
System.out.println(mapResult);
returnmapResult;
}
publicMap<String,List<String>>GetMapFromJson(StringjsonStr){
Map<String,List<String>>mapResult=newHashMap<String,List<String>>();
try{
JSONObjectresult=JSONObject.fromObject(jsonStr);//转换为JSONObject
JSONArraynameList=result.getJSONArray("result");//获取JSONArray
intlength=nameList.size();
for(inti=0;i<length;i++){
JSONObjecttempObject=nameList.getJSONObject(i);
Iteratoriter=tempObject.keys();
Stringkey=(String)iter.next();
StringkeyId=tempObject.getString(key);
List<String>objList=newArrayList<String>();
for(;iter.hasNext();){
StringkeyLocal=(String)iter.next();
//System.out.println(key+"="+tempObject.getString(keyLocal));
objList.add(tempObject.getString(keyLocal));
}
mapResult.put(keyId,objList);
}
}catch(Exceptione){
e.printStackTrace();
}
System.out.println(mapResult);
returnmapResult;
}
}
