方法一
这个方式的querys传的是参数参数可是单个参数/对象 host指的是远程调用的主机地址 headers指的是头信息可有可无 body指的是字符集的编码格式
public static String doPost(String host, String path,MapString, String headers,MapString, String querys,String body)throws Exception {HttpClient httpClient wrapClient(host);HttpPost request new HttpPost(buildUrl(host, path, querys));for (Map.EntryString, String e : headers.entrySet()) {request.addHeader(e.getKey(), e.getValue());}if (body!null !.equals(body) body.length()0) {request.setEntity(new StringEntity(body, utf-8));}//客户端执行。获取数据HttpResponse response httpClient.execute(request);//通过response里的getEntity()方法获取客户端的返回值然后return进行返回HttpEntity entity (HttpEntity) response.getEntity();if (entity ! null) {body EntityUtils.toString(entity, UTF-8);}//json根据key取valueEntityUtils.consume(entity);return body;}方法二
urlStr 第三方接口地址 param 数据参数JSON格式可以为null这个一般传的是对象参数
public static String doPost(String urlStr, String param) {HttpURLConnection connection null;InputStream is null;InputStreamReader rsd null;BufferedReader br null;OutputStream os null;OutputStreamWriter osw null;BufferedWriter bw null;StringBuffer sb new StringBuffer();try {URL url new URL(urlStr);connection (HttpURLConnection) url.openConnection();connection.setRequestMethod(POST);connection.setDoInput(true);connection.setDoOutput(true);connection.setUseCaches(false); //不缓存connection.setRequestProperty(connection, Keep-Alive); //设置保活连接connection.setRequestProperty(charset, UTF-8); //提交的数据编码connection.setRequestProperty(Content-type, application/json); //提交的数据格式connection.setRequestProperty(accept, application/json); //接收的数据格式connection.setConnectTimeout(30000); //30秒连接超时connection.setReadTimeout(30000); //30秒读取超时connection.connect();if (param ! null !.equals(param)) {os connection.getOutputStream();osw new OutputStreamWriter(os);bw new BufferedWriter(osw);bw.write(param);bw.flush();}int status connection.getResponseCode();if (status 200) {is connection.getInputStream();rsd new InputStreamReader(is, UTF-8);br new BufferedReader(rsd);String s;while ((s br.readLine()) ! null) {sb.append(s);}} else {return {\ResuleState\:\-1\,\Msg\:\连接异常\};}} catch (MalformedURLException e) {e.printStackTrace();} catch (ProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} finally {try {if (br ! null) {br.close();}if (rsd ! null) {rsd.close();}if (is ! null) {is.close();}if (bw ! null) {bw.close();}if (osw ! null) {osw.close();}if (os ! null) {os.close();}if (connection ! null) {connection.disconnect();}} catch (IOException e) {e.printStackTrace();}}return sb.toString();}举例 MapString, Object map new HashMap();map.put(currentPage,paramData.getCurrentPage());map.put(pageSize,paramData.getPageSize());map.put(addrList,paramData.getAddrList());map.put(startTime,paramData.getStartTime());map.put(endTime,paramData.getEndTime());String params JSONObject.toJSONString(map);String registerResult HttpUtils.doPost(base url, params);JSONObject result JSONObject.parseObject(registerResult);二、远程调用GET时的方法
方法一
public static String doGet(String url, MapString, Object param) {StringBuffer sb new StringBuffer(url?);IteratorMap.EntryString, Object iterator param.entrySet().iterator();while (iterator.hasNext()) {Map.EntryString, Object entry iterator.next();sb.append(entry.getKey()).append().append(entry.getValue()).append();}sb sb.deleteCharAt(sb.length() - 1);log.info(Http-GET 请求 sb.toString());String data ;// 创建请求对象HttpGet httpGet new HttpGet(sb.toString());// 设置参数HttpParams params new BasicHttpParams();HttpConnectionParams.setConnectionTimeout(params, 10000);HttpConnectionParams.setSoTimeout(params, 10000);// 执行请求的对象HttpClient client new DefaultHttpClient(params);// 执行请求镀锡try {HttpResponse resp client.execute(httpGet);// 判断是否响应成功if (resp.getStatusLine().getStatusCode() 200) {// 获取响应 的数据HttpEntity entity resp.getEntity();data EntityUtils.toString(entity, utf-8);}} catch (ClientProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return data;}方法二
public static String doGet(String host, String path, String method,String encoding,MapString, String headers,MapString, String querys)throws Exception {String body ;
// HttpClient httpClient wrapClient(host);CloseableHttpClient httpClient HttpClients.createDefault();CloseableHttpResponse response null;HttpGet request new HttpGet(buildUrl(host, path, querys));for (Map.EntryString, String e : headers.entrySet()) {request.addHeader(e.getKey(), e.getValue());}response httpClient.execute(request);HttpEntity entity (HttpEntity) response.getEntity();if (entity ! null) {body EntityUtils.toString(entity, encoding);}////json根据key取value// JSONObject jsonObject JSONObject.parseObject(body);
// String value jsonObject.getString(bodyData);
// JSONObject jsonObject1 JSONObject.parseObject(value);
// String list jsonObject1.getString(list);EntityUtils.consume(entity);response.close();
// System.out.println(数据内容 body);
// System.out.println(value list);return body;}
