在web开发中,我们经常需要模拟post及get请求,现在网上比较多的是使用httpclient3.x,然而httpclient4.x已经发布好几年了,而且4.x之后改名为HttpComponents,显然是今后的趋势.public void requestGet(String urlWithParams) throws Exception {
CloseableHttpClient httpclient = HttpClientBuilder.create().build();
//HttpGet httpget = new HttpGet("http://www.baidu.com/");
HttpGet httpget = new HttpGet(urlWithParams);
//配置请求的超时设置
RequestConfig requestConfig = RequestConfig.custom()
.setConnectionRequestTimeout(50)
.setConnectTimeout(50)
.setSocketTimeout(50).build();
httpget.setConfig(requestConfig);
CloseableHttpResponse response = httpclient.execute(httpget);
System.out.println("StatusCode -> " + response.getStatusLine().getStatusCode());
HttpEntity entity = response.getEntity();
String jsonStr = EntityUtils.toString(entity);//, "utf-8");
System.out.println(jsonStr);
httpget.releaseConnection();
}public void requestPost(String url,List<NameValuePair> params) throws ClientProtocolException, IOException {
CloseableHttpClient httpclient = HttpClientBuilder.create().build();
HttpPost httppost = new HttpPost(url);
httppost.setEntity(new UrlEncodedFormEntity(params));
CloseableHttpResponse response = httpclient.execute(httppost);
System.out.println(response.toString());
HttpEntity entity = response.getEntity();
String jsonStr = EntityUtils.toString(entity, "utf-8");
System.out.println(jsonStr);
httppost.releaseConnection();
}
public static void main(String[] args){
try {
String loginUrl = "http://localhost:8080/yours";
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", "zhang"));
params.add(new BasicNameValuePair("passwd", "123"));
requestPost(loginUrl,params);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
