小程序实名认证

• 用户在前端输入 姓名 , 身份证号码
• 前端 做 人脸比对
• 前端的比对结果请求自己的后端,获取userIdKey, 核验 输入的身份证号码是否匹配

通过姓名和身份证号获取UserIdKey

public String getUserIdKey(@NonNull String name, @NonNull String idCard) {
    // 参考 https://developers.weixin.qq.com/community/business/doc/000442d352c1202bd498ecb105c00d

    final String accessToken = talentMiniProgramService.getAccessToken();

    String uri = miniprogramProperty.getNameIdCardUri() + "?" + "access_token=" + accessToken;

    Map<String, String> params = new HashMap<>();
    params.put("name", name);
    params.put("id_card_number", idCard);
//        params.put("out_seq_no", TsidCreator.getTsid().toString());
    BodyInserter bodyInserter = BodyInserters.fromValue(params);
    Mono<String> code2SessionResultMono = WebClient.create()
            .post().uri(uri).body(bodyInserter).retrieve().bodyToMono(String.class);
    String result = code2SessionResultMono.block();
    TalentMiniProgramServiceImpl.CheckUserResult checkUserResult;
    try {
        checkUserResult = objectMapper.readValue(result, TalentMiniProgramServiceImpl.CheckUserResult.class);
    } catch (JsonProcessingException e) {
        log.error("小程序结果解析失败,result={}", result);
        throw new ServiceException("小程序登录结果解析失败");
    }
    if (checkUserResult == null || checkUserResult.getErrcode() == null) {
        log.error("调用userIdKey失败");
        throw new ServiceException("调用userIdKey失败");
    }
    if (checkUserResult.getErrcode() != 0) {
        log.error("获取微信平台userIdKey失败,code={}, errorMsg={}", checkUserResult.getErrcode(), checkUserResult.getErrmsg());
        throw new ServiceException("获取微信平台userIdKey失败,errcode=" + checkUserResult.getErrcode());
    }
    return checkUserResult.getUser_id_key();
}

用户核身结果结果校验

@Override
   public GetInfoResult getInfo(@NonNull String verifyResult, @NonNull String userIdKey) {
       final String uri = "https://api.weixin.qq.com/cityservice/face/identify/getinfo?access_token=" + talentMiniProgramService.getAccessToken();
       Map<String, String> params = new HashMap<>();
       params.put("verify_result", verifyResult);
       params.put("user_id_key", userIdKey);
       BodyInserter bodyInserter = BodyInserters.fromValue(params);
       Mono<String> code2SessionResultMono = WebClient.create()
               .post().uri(uri).body(bodyInserter).retrieve().bodyToMono(String.class);
       String result = code2SessionResultMono.block();
       GetInfoResult infoResult;
       try {
           infoResult = objectMapper.readValue(result, GetInfoResult.class);
       } catch (JsonProcessingException e) {
           log.error("getInfo小程序结果解析失败,result={}", result);
           throw new ServiceException("小程序登录结果解析失败");
       }
       if (infoResult.getErrcode() == null || infoResult.getErrcode() == null) {
           log.error("调用getInfo失败");
           throw new ServiceException("调用GetInfo失败");
       }
       if (infoResult.getErrcode() != 0 || infoResult.getErrcode() != 0) {
           log.error("getInfo人脸核身失败,code={}, errorMsg={}", infoResult.getErrcode(), infoResult.getErrmsg());
           throw new ServiceException("人脸核身失败errCode=" + infoResult.getErrcode());
       }
       log.info("getinfo结果,infoResult={}", infoResult);
       return infoResult;
   }
