调用百度云身份证识别接口_百度实名认证接口api的请求

一、 引入Maven依赖

<dependency>
        <groupId>com.baidu.aip</groupId>
        <artifactId>java-sdk</artifactId>
        <version>${version}</version>
    </dependency>

二、接口

@ApiOperation("用户实名认证")
    @PostMapping("/authentication")
    public ResObject authentication(@RequestBody DdcRealNameUser ddcRealNameUser)throws Exception {
        Map maps = new HashMap();
        ResObject resObject = null;
        String idcardIdentificate = "https://aip.baidubce.com/rest/2.0/ocr/v1/idcard";
        // 本地图片路径
        String path = ddcRealNameUser.getRealnameauthfront();
        String filePath = path;//#####本地文件路径#####
        byte[] imgData = FileUtil.readFileByBytes(filePath);
        String imgStr = Base64Util.encode(imgData);
        // 识别身份证正面id_card_side=front;识别身份证背面id_card_side=back;
        String params = "id_card_side=front&" + URLEncoder.encode("image", "UTF-8") + "="
                + URLEncoder.encode(imgStr, "UTF-8");
        /**
         * 线上环境access_token有过期时间， 客户端可自行缓存，过期后重新获取。
         */
        String accessToken = OcrUtil.getAuth();//#####调用鉴权接口获取的token#####
        String results = HttpUtil.post(idcardIdentificate, accessToken, params);
        Map<String, String> map = new HashMap<>();
        JSONObject jsonObject = JSONObject.parseObject(results);
        JSONObject words_result = jsonObject.getJSONObject("words_result");
        if (words_result == null || words_result.isEmpty()) {
//            throw new MyException("请提供身份证"+side+"图片");
        }
        for (String key : words_result.keySet()) {
            JSONObject result = words_result.getJSONObject(key);
            String info = result.getString("words");
            switch (key) {
                case "姓名":
                    map.put("name", info);
                    break;
                case "性别":
                    map.put("sex", info);
                    break;
                case "民族":
                    map.put("nation", info);
                    break;
                case "出生":
                    map.put("birthday", info);
                    break;
                case "住址":
                    map.put("address", info);
                    break;
                case "公民身份号码":
                    map.put("idNumber", info);
                    break;
                case "签发机关":
                    map.put("issuedOrganization", info);
                    break;
                case "签发日期":
                    map.put("issuedAt", info);
                    break;
                case "失效日期":
                    map.put("expiredAt", info);
                    break;
            }
            int count = 1;
            for (int i = 0; i < results.length(); i++) {
                System.out.print(results.charAt(i));
                count++;
                if (count % 120 == 0) {
                    System.out.print("\n");
                }
            }
        }
        resObject = new ResObject(0, "success", map);
        return resObject;

三、生成token方法

  // Access_Token获取
    private static final String ACCESS_TOKEN_HOST = "https://aip.baidubce.com/oauth/2.0/token?";
    // 身份证识别请求URL
    private static final String OCR_HOST = "https://aip.baidubce.com/rest/2.0/ocr/v1/idcard?";
    // apiKey,secretKey
    private static final String API_KEY ="";
    private static final String SECRET_KEY = "";
    public static String getAuth() {
        // 官网获取的 API Key 更新为你注册的
        String clientId = "";//百度云应用的AK
        // 官网获取的 Secret Key 更新为你注册的
        String clientSecret = "";//百度云应用的SK
        return getAuth(clientId, clientSecret);
    }

    public static 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);
            org.json.JSONObject jsonObject = new org.json.JSONObject(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;
    }
