目前有一个需求是需要跨服务调用的，通过后端直接访问，直接通过url访问记录一下，后面更简单的去处理。
首先是最古老的方式HttpURLConnection
public JSONArray sendAuthorization(){JSONObject jsonObject = new JSONObject();jsonObject.put("staffNo","000222");try {// 定义URL和凭据信息String urlString = "http://127.0.0.1:12001/sso/sendPersonAuthorization";// 构建URL对象URL url = new URL(urlString);// 打开连接HttpURLConnection connection = (HttpURLConnection) url.openConnection();// 设置请求方法为POSTconnection.setRequestMethod("POST");// 设置请求头，指定请求体格式为 JSONconnection.setRequestProperty("Content-Type", "application/json");connection.setRequestProperty("Authorization", "Bearer 96228ded-0c64-4ffe-a487-c1ed0c6918bc");// 启用输出流，并将 JSON 请求体写入连接connection.setDoOutput(true);OutputStream os = connection.getOutputStream();os.write(jsonObject.toString().getBytes());os.flush();os.close();// 获取响应码int responseCode = connection.getResponseCode();System.out.println("Response Code: " + responseCode);// 读取响应内容BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));String inputLine;StringBuffer response = new StringBuffer();while ((inputLine = in.readLine()) != null) {response.append(inputLine);}in.close();JSONArray jsonObject1 = JSONArray.parseArray(response.toString());return jsonObject1;// 打印响应内容} catch (Exception e) {e.printStackTrace();}return null;}
处理方式相当古老了，但是别说好用还。
新的方式RestTemplate
@PostMapping("/sendPersonAuthorization")public List<TokenVO> sendPersonAuthorization() {// 请求URLString url = "http://127.0.0.1:12001/login";// 请求参数HashMap<String, String> params = new HashMap<>();params.put("ticket", Sm2Encryptor.encryptString("mima"));params.put("captcha", "123");params.put("token", "123");// HTTP头HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.APPLICATION_JSON_UTF8); // 设置Content-Type为application/x-www-form-urlencodedheaders.set("Clientid", "bVS46ElU"); // 设置自定义HTTP头HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(null, headers);RestTemplate restTemplate = new RestTemplate();// 查询所有生效的用户List<LoginUserDetailVO> voList = basePortaluserMapper.findUserInfoList();return voList.stream().map(vo -> {params.put("per", Sm2Encryptor.encryptString(vo.getUsername()));// 构建带查询参数的完整URLUriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url);for (Map.Entry<String, String> entry : params.entrySet()) {builder.queryParam(entry.getKey(), entry.getValue());}String urlWithParams = builder.toUriString();ResponseEntity<String> response = restTemplate.exchange(urlWithParams, HttpMethod.POST, requestEntity, String.class);String token = "Bearer " + ((JSONObject) JSON.parseObject(response.getBody()).get("data")).get("value");TokenVO tokenVO = new TokenVO();BeanUtils.copyProperties(vo, tokenVO);tokenVO.setToken(token);return tokenVO;}).collect(Collectors.toList());}
使用RestTemplate 方式去进行访问，使用Stream流进行返回
