HttpClient发送Post请求,get请求
// 创建默认的httpclient实例 CloseableHttpClient httpclient = getHttpClient(); CloseableHttpResponse response = null; // 创建httpPost HttpPost httpPost = new HttpPost("url地址");
httpPost.setHeader(HTTP.CONTENT_TYPE, "application/json; charset=utf-8"); try { StringEntity param = new StringEntity(params, ContentType.APPLICATION_JSON); httpPost.setEntity(param); response = httpclient.execute(httpPost); HttpEntity entity = response.getEntity(); if(entity != null){ InputStream is = entity.getContent(); } } catch (Exception e) { LOG.error("sendPostRequest error:", e); } finally { try { //关闭连接,释放资源 response.close(); httpclient.close(); } catch (Exception e) { LOG.error("HttpClient close error:", e); } }
发送Get请求
CloseableHttpClient httpclient = getHttpClient(); CloseableHttpResponse response = null; HttpGet httpget = new HttpGet("url地址"); try { response = httpclient.execute(httpget); HttpEntity entity = response.getEntity(); if(entity != null){ InputStream is = entity.getContent(); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally { try { //关闭连接,释放资源 response.close(); closeHttpClient(httpclient); } catch (Exception e) { LOG.error("HttpClient close error:", e); } }
