Java模拟HttpClient进行Get和Post提交

使用Java模拟客户端进行提交,需要用到apache http client jar,这里用的是4.4版本

GET:

public void GetURL(){
  String strResp="";
  String url="www.baidu.com";
  int statuscode=0;
  CloseableHttpClient client=HttpClients.createDefault();
  HttpGet request=new HttpGet(url);
  try{
   HttpResponse response=client.execute(request);
   statuscode=response.getStatusLine().getStatusCode();
   if(statuscode==200){
    strResp=EntityUtils.toString(response.getEntity());//返回的内容
   }
  }catch(Exception e){
   e.printStackTrace();
  }

 

POST:

public String PostURL(){  

  String strResp="";
  String url="www.baidu.com";
  int statuscode=0;

 CloseableHttpClient client = HttpClients.createDefault();

 HttpPost request=new HttpPost(url);

 JSONStringer jsonbody;   

 try{   

   jsonbody=(JSONStringer) new JSONStringer().object().key("vehicleID").value("8856017585").endObject(); 

   StringEntity se=new StringEntity(jsonbody.toString(),"UTF-8"); 

   se.setContentType("application/json");

   request.setEntity(se); //设置要POST的内容,当前这里使用的是json格式

   HttpResponse response=client.execute(request);  

   statuscode=response.getStatusLine().getStatusCode();  

   if(statuscode==HttpStatus.SC_OK){   

     strResp=new String(EntityUtils.toString(response.getEntity()).getBytes("UTF-8")); }

     client.close();  

   }catch(Exception e){

     e.printStackTrace();   }

  return strResp;  }
