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;  }
