第一步:是要拿到access_token这个秘钥。
| 参数 | 值 |
| access_token | 通过API Key和Secret Key获取的access_token,参考“Access Token获取 ” |
AIP:https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials
- static final OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();
- MediaType mediaType = MediaType.parse("application/json");
- okhttp3.RequestBody body = okhttp3.RequestBody.create(mediaType, "&client_id="+API_KEY+"&client_secret="+SECRET_KEY);
- Request request = new Request.Builder()
- .url("https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials")
- .method("POST", body)
- .addHeader("Content-Type", "application/json")
- .addHeader("Accept", "application/json")
- .build();
- Response response = null;
- try {
- response = HTTP_CLIENT.newCall(request).execute();
- } catch (IOException e) {
- throw new RuntimeException(e);
- }
- //只会调用一次
- // System.out.println(response.body().string());
- try {
- JSONObject jsonObject = JSONObject.parseObject(response.body().string());
- String accessToken = jsonObject.getString("access_token");
- System.out.println("accessToken="+accessToken);
第二步:上传身份证,验证身份证
请求参数:
- // 请求url
- String url = "https://aip.baidubce.com/rest/2.0/ocr/v1/idcard";
- //图片地址
- String filePath = pats;
- System.out.println("filePath=" + filePath);
- // String filePath = "C://Users/29291/Desktop/12.png";
- //String filePath = "https://gulimall-vues.oss-cn-chengdu.aliyuncs.com/11.jpg";
- byte[] imgData = FileUtil.readFileByBytes(filePath);
- String imgStr = Base64Util.encode(imgData);
- String imgParam = URLEncoder.encode(imgStr, "UTF-8");
- //拼接参数
- String param = "id_card_side=" + "back" + "&image=" + imgParam + "&detect_risk=" + "true";
- // 注意这里仅为了简化编码每一次请求都去获取access_token,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 accessTokens = accessToken;
- String result = HttpUtils.post(url, accessTokens, param);
- System.out.println("result=" + result);
- JSONObject jsonObjects = JSONObject.parseObject(result);
- String riskType = jsonObjects.getString("risk_type");
- System.out.println("riskType=" + riskType);
- if (!riskType.equals("normal")) {
- new File(pats).delete();
- System.out.println("请上传有效身份证");
- return R.error("请上传有效身份证");
- }
- //身份证信息
- String name = jsonObjects.getJSONObject("words_result").getJSONObject("姓名").getString("words");
- System.out.println("name=" + name);
- //判断信息是否一致
- if (!name.equals(fullName)) {
- new File(pats).delete();
- return R.error("信息错误,请重新认证");
- }
- String nation = jsonObjects.getJSONObject("words_result").getJSONObject("民族").getString("words");
- String address = jsonObjects.getJSONObject("words_result").getJSONObject("住址").getString("words");
- String card = jsonObjects.getJSONObject("words_result").getJSONObject("公民身份号码").getString("words");
- String birthday = jsonObjects.getJSONObject("words_result").getJSONObject("出生").getString("words");
- String sex = jsonObjects.getJSONObject("words_result").getJSONObject("性别").getString("words");
- new File(pats).delete();
- Courier courier1=new Courier();
- courier1.setIdentityStatus("1");
- courier1.setCourierId(courierId);
- courierService.updateCourier(courier1);
| 参数 | 是否必选 | 类型 | 可选值范围 | 说明 |
| image | 和url二选一 | string | - | 图像数据,base64编码后进行urlencode,要求base64编码和urlencode后大小不超过4M,最短边至少15px,最长边最大4096px,支持jpg/jpeg/png/bmp格式 |
| url | 和image二选一 | string | - | 图片完整URL,URL长度不超过1024字节,URL对应的图片base64编码后大小不超过4M,最短边至少15px,最长边最大4096px,支持jpg/jpeg/png/bmp格式,当image字段存在时url字段失效 |
| id_card_side | 是 | string | front/back | -front:身份证含照片的一面 |
| detect_risk | 否 | string | true/false | 是否开启身份证风险类型(身份证复印件、临时身份证、身份证翻拍、修改过的身份证)检测功能,默认不开启,即:false。 |
| detect_quality | 否 | string | true/false | 是否开启身份证质量类型(边框/四角不完整、头像或关键字段被遮挡/马赛克)检测功能,默认不开启,即:false。 |
| detect_photo | 否 | string | true/false | 是否检测头像内容,默认不检测。可选值:true-检测头像并返回头像的 base64 编码及位置信息 |
| detect_card | 否 | string | true/false | 是否检测身份证进行裁剪,默认不检测。可选值:true-检测身份证并返回证照的 base64 编码及位置信息 |
