Get请求方式举例

代码:

public class Test { 
    public static void main(String[] args) { 
    System.out.println(doGet("http://www.baidu.com")); } /** * 测试get请求方式 * * @param apiUrl 链接 * @return 请求返回值 * @author 明快de玄米61 * @date 2021/09/05 */ private static String doGet(String apiUrl) { 
    CloseableHttpClient client = null; CloseableHttpResponse response = null; try { 
    // 创建客户端连接对象 client = HttpClients.createDefault(); // 构建Get请求对象 HttpGet get = new HttpGet(apiUrl); // 设置超时时间,其中connectionRequestTimout(从连接池获取连接的超时时间)、connetionTimeout(客户端和服务器建立连接的超时时间)、socketTimeout(客户端从服务器读取数据的超时时间),单位都是毫秒 RequestConfig config = RequestConfig.custom().setConnectTimeout(10000).setConnectionRequestTimeout(3000) .setSocketTimeout(20000).build(); get.setConfig(config); // 获取返回对象 response = client.execute(get); // 整理返回值 HttpEntity entity = response.getEntity(); String result = EntityUtils.toString(entity); return result; } catch (Exception e) { 
    e.printStackTrace(); return null; } finally { 
    // 关闭连接和流 try { 
    if (client != null) { 
    client.close(); } if (response != null) { 
    response.close(); } } catch (Exception e) { 
    e.printStackTrace(); } } } } 

结果:

POST请求方式举例

例1:获取token
代码
public class Test { 
    public static void main(String[] args) { 
    System.out.println("token:" + doPost("接口地址", "root", "", "default")); } /** * 测试post请求方式 * * @param apiUrl 接口地址 * @param username 用户名 * @param password 密码 * @param tenantUrl 租户标识 * @return * @author 明快de玄米61 * @date 2021/9/6 23:12 **/ private static String doPost(String apiUrl, String username, String password, String tenantUrl) { 
    CloseableHttpClient client = null; CloseableHttpResponse response = null; String idToken = null; try { 
    // 创建客户端连接对象 client = HttpClients.createDefault(); // 构建Post请求对象 HttpPost post = new HttpPost(apiUrl); // 设置传送的内容类型是json格式 post.setHeader("Content-Type", "application/json;charset=utf-8"); // 接收的内容类型也是json格式 post.setHeader("Accept", "application/json;charset=utf-8"); // 设置超时时间,其中connectionRequestTimout(从连接池获取连接的超时时间)、connetionTimeout(客户端和服务器建立连接的超时时间)、socketTimeout(客户端从服务器读取数据的超时时间),单位都是毫秒 RequestConfig config = RequestConfig.custom().setConnectTimeout(10000).setConnectionRequestTimeout(3000).setSocketTimeout(20000).build(); post.setConfig(config); // 准备数据 JSONObject json = new JSONObject(); json.put("username", username); json.put("password", DigestUtils.md5Hex(password)); json.put("tenantUrl", tenantUrl); // 设置请求体 post.setEntity(new StringEntity(json.toString(), "UTF-8")); // 获取返回对象 response = client.execute(post); // 整理返回值 HttpEntity entity = response.getEntity(); String result = EntityUtils.toString(entity); // 获取idToken if (result != null && !"".equals(result.trim())) { 
    JSONObject rjo = JSONObject.parseObject(result, Feature.OrderedField); if (rjo != null && rjo.containsKey("retCode")) { 
    int retCode = rjo.getInteger("retCode"); if (retCode == 0 && rjo.containsKey("data")) { 
    JSONObject data = rjo.getJSONObject("data"); if (null != data && data.containsKey("idToken")) { 
    // 获取最终想要的数据 idToken = data.getString("idToken"); } } } } } catch (SocketTimeoutException e) { 
    e.printStackTrace(); throw new RuntimeException("获取token出现连接/超时异常"); } catch (Exception e) { 
    e.printStackTrace(); throw new RuntimeException("获取token时执行内部代码时出现异常"); } finally { 
    try { 
    if (client != null) { 
    client.close(); } if (response != null) { 
    response.close(); } } catch (Exception e) { 
    e.printStackTrace(); } } return idToken; } } 
结果
token:853b7c87-c16f-4e3b-96c4-9701fe3448ab

例2:获取知识图谱信息
代码
public class Test { 
    public static void main(String[] args) { 
    System.out.println("图谱结果:" + doPost("接口地址", "实体id", "token令牌", "图谱实例数量")); } private static String doPost(String apiUrl, String instanceId, String idToken, Integer number) { 
    CloseableHttpClient client = null; CloseableHttpResponse response = null; String result = null; try { 
    // 创建客户端连接对象 client = HttpClients.createDefault(); // 构建Post请求对象 HttpPost post = new HttpPost(apiUrl); // 设置传送的内容类型是json格式 post.setHeader("Content-Type", "application/json;charset=utf-8"); // 接收的内容类型也是json格式 post.setHeader("Accept", "application/json;charset=utf-8"); post.setHeader("Authorization", "Bearer " + idToken); // 设置超时时间,其中connectionRequestTimout(从连接池获取连接的超时时间)、connetionTimeout(客户端和服务器建立连接的超时时间)、socketTimeout(客户端从服务器读取数据的超时时间),单位都是毫秒 RequestConfig config = RequestConfig.custom().setConnectTimeout(10000).setConnectionRequestTimeout(3000).setSocketTimeout(20000).build(); post.setConfig(config); // 准备数据 JSONObject json = new JSONObject(); json.put("pageNum", 0); json.put("pageSize", number); JSONObject data = new JSONObject(); String[] status = { 
   "on"}; data.put("status", status); String[] instanceIdSet = { 
   instanceId}; data.put("instanceIdSet", instanceIdSet); String[] checked = { 
   "on"}; data.put("checked", checked); json.put("data", data); // 设置请求体 post.setEntity(new StringEntity(json.toString(), "UTF-8")); // 获取返回对象 response = client.execute(post); // 整理返回值 HttpEntity entity = response.getEntity(); result = EntityUtils.toString(entity); } catch (SocketTimeoutException e) { 
    e.printStackTrace(); throw new RuntimeException("调用获取图谱接口出现连接/超时异常"); } catch (Exception e) { 
    e.printStackTrace(); throw new RuntimeException("调用获取图谱接口执行内部代码时出现异常"); } finally { 
    try { 
    if (client != null) { 
    client.close(); } if (response != null) { 
    response.close(); } } catch (Exception e) { 
    e.printStackTrace(); } } return result; } }

例3:调用ES高级接口获取实体信息
代码
public class HTTPURLConnectionTest { 
    public static void main(String[] args) { 
    System.out.println("图谱结果:" + doPost("接口地址", "图谱id", "实体id", "token令牌")); } private static String doPost(String apiUrl, String ontologyId, String instanceId, String idToken) { 
    CloseableHttpClient client = null; CloseableHttpResponse response = null; String result = null; try { 
    // 创建客户端连接对象 client = HttpClients.createDefault(); // 构建Post请求对象 HttpPost post = new HttpPost(apiUrl); // 设置传送的内容类型是json格式 post.setHeader("Content-Type", "application/json;charset=utf-8"); // 接收的内容类型也是json格式 post.setHeader("Accept", "application/json;charset=utf-8"); post.setHeader("Authorization", "Bearer " + idToken); // 设置超时时间,其中connectionRequestTimout(从连接池获取连接的超时时间)、connetionTimeout(客户端和服务器建立连接的超时时间)、socketTimeout(客户端从服务器读取数据的超时时间),单位都是毫秒 RequestConfig config = RequestConfig.custom().setConnectTimeout(10000).setConnectionRequestTimeout(3000).setSocketTimeout(20000).build(); post.setConfig(config); // 准备数据 JSONObject json = new JSONObject(); json.put("pageNum", 0); json.put("pageSize", 1); JSONObject data = new JSONObject(); data.put("ontologyId", ontologyId); data.put("needProperties", true); JSONArray expresses = new JSONArray(); JSONObject arr = new JSONObject(); arr.put("sign", "="); arr.put("value", instanceId); arr.put("key", "id"); arr.put("dataType", "String"); expresses.add(arr); data.put("expresses", expresses); json.put("data", data); // 设置请求体 post.setEntity(new StringEntity(json.toString(), "UTF-8")); // 获取返回对象 response = client.execute(post); // 整理返回值 HttpEntity entity = response.getEntity(); result = EntityUtils.toString(entity); } catch (SocketTimeoutException e) {

    e.printStackTrace(); throw new RuntimeException("调用获取图谱接口执行内部代码时出现异常"); } finally { 
    try { 
    if (client != null) { 
    client.close(); } if (response != null) { 
    response.close(); } } catch (Exception e) { 
    e.printStackTrace(); } } return result; } }
