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; }
