controller代码

 //可以写入配置文件String clientId = "去百度云注册账号获取";// 官网获取的 Secret Key 更新为你注册的String clientSecret = "去百度云注册账号获取";/*** 身份证正面* @return*/@GetMapping("/IdCard/front/{uid}")@ApiOperation(value = "身份证正面")public IdCard idCardFront(@PathVariable(name = "uid")int uid){//Token有效期为30天 2592000秒 可以将token存入redis避免重复获取,也可以每次请求获取String Token =authService.getAuth(clientId,clientSecret);//filePath 为本地身份证地址 需要从数据库查询PmsPhoto pmsPhoto = pmsPhotoService.selectPmsPhotoById(uid);//拿到百度返回的json串String idcardResult = idcardService.idcard(pmsPhoto.getIdcardFrontBig(),Token);//将json串转化成类IdCard idcard = jsonService.getIdcardFront(idcardResult);PmsUser pmsUser=new PmsUser();//copy对象BeanUtils.copyProperties(idcard, pmsUser);pmsUser.setId(uid);pmsUserService.updatePmsUser(pmsUser);return idcard;}

获取Ocr权限 authService  获取Token

 /*** 获取API访问token* 该token有一定的有效期，需要自行管理，当失效时需重新获取.* @param ak - 百度云官网获取的 API Key* @param sk - 百度云官网获取的 Secret Key* @return assess_token 示例：* "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567"*/public String getAuth(String ak, String sk) {// 获取token地址String authHost = "https://aip.baidubce.com/oauth/2.0/token?";String getAccessTokenUrl = authHost// 1. grant_type为固定参数+ "grant_type=client_credentials"// 2. 官网获取的 API Key+ "&client_id=" + ak// 3. 官网获取的 Secret Key+ "&client_secret=" + sk;try {URL realUrl = new URL(getAccessTokenUrl);// 打开和URL之间的连接HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection();connection.setRequestMethod("GET");connection.connect();// 获取所有响应头字段Map<String, List<String>> map = connection.getHeaderFields();// 遍历所有的响应头字段for (String key : map.keySet()) {System.err.println(key + "--->" + map.get(key));}// 定义 BufferedReader输入流来读取URL的响应BufferedReader in = new BufferedReader(new  InputStreamReader(connection.getInputStream()));String result = "";String line;while ((line = in.readLine()) != null) {result += line;}/*** 返回结果示例*/System.err.println("result:" + result);JSONObject jsonObject = JSONObject.parseObject(result);String access_token = jsonObject.getString("access_token");return access_token;} catch (Exception e) {System.err.printf("获取token失败！");e.printStackTrace(System.err);}return null;}

idcardService根据百度ocr示例代码进行修改，param参数可以根据百度Ocr示例参数进行自定义

  // 请求urlstatic String url = "https://aip.baidubce.com/rest/2.0/ocr/v1/idcard";// aes key 从console控制台获取static String aesKey = "454872cbcd90a105";static byte[] originAesKey = null;public static String idcard(String filePath,String Token) {try {// 本地文件路径
//            String filePath = "D:\\a\\hyy.jpg";byte[] imgData = FileUtil.readFileByBytes(filePath);//加密图片String imgStr = encryptImg(aesKey, imgData);String imgParam = URLEncoder.encode(imgStr, "UTF-8");String param = "id_card_side=" + "front" +"&image=" + imgParam +"&AESEncry=" + true ;String encryptResult = HttpUtil.post(url, Token, param);//解密图片String decryptResult = parseResult(encryptResult);return decryptResult;} catch (Exception e) {e.printStackTrace();}return null;}

jsonService 从百度返回的json数据中取出自己需要的

  public IdCard getIdcardFront(String idcardResult){JSONObject words_result =JSONObject.parseObject(idcardResult);//从JSONObject中取对应的值JSONObject JsonidCard = new JSONObject();JsonidCard.put("name", words_result.getJSONObject("words_result").getJSONObject("姓名").get("words"));JsonidCard.put("nation", words_result.getJSONObject("words_result").getJSONObject("民族").get("words"));JsonidCard.put("address", words_result.getJSONObject("words_result").getJSONObject("住址").get("words"));JsonidCard.put("sex", words_result.getJSONObject("words_result").getJSONObject("性别").get("words"));JsonidCard.put("birth", words_result.getJSONObject("words_result").getJSONObject("出生").get("words"));JsonidCard.put("number", words_result.getJSONObject("words_result").getJSONObject("公民身份号码").get("words"));//JSONObject转对象IdCard idCard = JSON.toJavaObject(JsonidCard,IdCard.class);return idCard;}

总结：1.支持本地图片和url

           2.需要Maven依赖和工具类支持，可以从以下文档获取，也可以从官方文档获取

           3.代码仅供参考更详细内容可以参考以下文档：
