Django调用百度AI接口实现人脸注册登录代码实例 2024/11/19 饿虎岗资源网

面部识别----考勤打卡、注册登录、面部支付等等...感觉很高大上，又很方便，下面用python中的框架--django完成一个注册登录的功能，调用百度AI的接口，面部识别在网上也有好多教程，可以自己建模，训练模型，但是这都需要大量的数据去提高模型的准确度，我们直接用了百度AI的接口，十分的快捷、高效、准确，下来码一下代码啦！！

首先需要在百度AI官网注册一个应用，免费，并提供强大的人脸库。

　　1.注册表单

<div class="tab-content">
                    <div class="tab-content-inner active" data-content="signup">
                      <!-- <form action="{% url 'regist' %}" method="POST"> -->
                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="text" class="form-control" id="username" placeholder="用户名">
                          </div>
                        </div>
                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="text" class="form-control" id="mobile" placeholder="手机号">
                          </div>
                        </div>
                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="password" class="form-control" id="password" placeholder="密码">
                          </div>
                        </div>
                        <div class="row form-group">
                            <div class="col-md-12">
                              <!-- <input type="text" class="form-control" id="mobile_code" placeholder="验证码">
                              <input type="button" value=" 获取验证码" id="zphone"> -->
                            </div>
                        </div>
                        <div class="row form-group">
                          <div class="col-md-12">
                            <label for="password2"><font color='green'>新用户点击注册会有面部特征收集哦！</font></label>
                          </div>
                        </div>

                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="submit" class="btn btn-primary" value="注册" id="regist">
                          </div>
                        </div>
                      <!-- </form>   -->
                    </div>

　　2.注册时调用摄像头，ajax封装给后端的数据

<!-- jQuery -->
  <script src="/UploadFiles/2021-04-08/jquery.min.js">

　　3.将已经注册的应用中的各种id和key贴上来


# 导入百度AI
from django.apps import AppConfig
from aip import AipFace
import json
# django内置事务
from django.db import transaction
# 导入状态码
from jyapp.ErrorCode import * # 官网给出的状态码，通过pandas读出保存到

# 百度AI基本信息
class AppConfig(AppConfig):
  name = ''
  APP_ID = ''
  API_KEY = ''
  SECRECT_KEY = ''
  client = AipFace(APP_ID,API_KEY,SECRECT_KEY)
  client.setConnectionTimeoutInMillis(1000*5)
  client.setSocketTimeoutInMillis(1000*5)


　　4.注册接口，按照接口文档传入必须的参数，手机验证码功能已在本文中注释掉，需要时自行百度。


# 注册
class Regist(View):
  def get(self,request):
    return render(request,'moban_index.html')
  def post(self,request):
    # 获取前端数据
    imagecontent = request.POST.get('imagecontent')
    username = request.POST.get('username')
    mobile = request.POST.get('mobile')
    password = request.POST.get('password')
    # mobile_code = request.POST.get('mobile_code')
    # print(imagecontent,username,mobile,password,mobile_code)
    # mobile_code_right = request.session.get('message_code')
    if not all([imagecontent,username,mobile,password]):
      return JsonResponse({'result':'注册信息不能为空'})
    # if mobile_code != mobile_code_right:
    #   return JsonResponse({'result':'请输入正确的验证码'})
    else:
      # 验证该用户是否存在
      user = models.User.objects.filter(mobile=mobile)
      if user:
        return JsonResponse({'result':'该用户已存在，请直接登录'})
      else:
        try:
          # 引入事务
          with transaction.atomic():  
            # 分割字符串
            base_data = imagecontent.split(',')[1]
            # base64解码
            base64_decode = base64.b64decode(base_data)
            # 图片写入本地
            with open('static/image/'+mobile+'.jpeg', 'wb') as f:
              f.write(base64_decode)
            # 添加到mysql数据库
            models.User.objects.create(
              imagecontent = 'static/image/'+mobile+'.jpeg',  # 可以根据需求是否保存注册照片到数据库，也可以通过百度AI人脸库查看
              username = username,
              mobile = mobile,
              password = password,
            )
            imageType = 'BASE64'
            groupId = 'usergroup'  # 自定义
            userId = mobile
            # 加入可选参数
            options = {}
            options['user_info'] = username
            options['quality_control'] = 'NORMAL'
            options['liveness_control'] = 'LOW'
            result = AppConfig.client.addUser(base_data,imageType,groupId,userId,options)
            print(result)
            error_code = result['error_code']
            if isinstance(error_code,int) and error_code == 0:
              request.session['mobile'] = mobile
              return JsonResponse({'code':200,'result':'注册成功'})
              # return JsonResponse({'result':'注册成功'})
            else:
              error = ErrorCode().getErrorInfo(error_code)
              return JsonResponse({'result':'{}'.format(error)})
        except:
          return JsonResponse({'result':'注册失败'})


　　5.登录.html


<div class="tab-content-inner" data-content="login">
                      <!-- <form action="{% url 'login' %}" method="POST"> -->
                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="text" class="form-control" id="mobile1" placeholder="请输入手机号">
                          </div>
                        </div>
                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="password" class="form-control" id="password1" placeholder="请输入密码">
                          </div>
                        </div>

                        <div class="row form-group">
                          <div class="col-md-12">
                            <input type="submit" class="btn btn-primary" value="密码登陆" id="login">
                            <input type="submit" class="btn btn-primary" value="人脸登陆" id="login_face">
                          </div>
                        </div>
                      <!-- </form>   -->
                    </div>


　　6.ajax封装登录信息


document.getElementById('login_face').addEventListener('click', function () {
        if (videoPlaying) {
          mycanvas = document.getElementById('canvas');
          mycanvas.width = v.videoWidth;
          mycanvas.height = v.videoHeight;
          mycanvas.getContext('2d').drawImage(v, 0, 0);
          data = mycanvas.toDataURL('image/webp');
          document.getElementById('photo').setAttribute('src', data);

          $.ajax({
            type:"POST",
            url:'http://127.0.0.1:8000/login_face/',
            data:{mobile:$('#mobile1').val(),imagecontent:data},
            dataType:"json",
            success:function(data){
              $('#resText').text(data['result']);
              document.getElementById('photo').setAttribute('src','static/'+data['point72src']);
              console.log(data['point72src'])
              if(data.code == 200){
                alert(data.result)
                window.location.href='http://127.0.0.1:8000/idcard/'
              }else{
                alert(data.result);
              }
            }
          })
        }
      }, false);


　　7.人脸快速登录


class Login_face(View):
  def get(self,request):
    return render(request,'moban_index.html')
  def post(self,request):
    imagecontent = request.POST.get('imagecontent')
    mobile = request.POST.get('mobile')
    if not all([imagecontent,mobile]):
      return JsonResponse({'code':100,'result':'登录信息不能为空'})
    else:
      user = models.User.objects.filter(mobile=mobile)
      if not user:
        return JsonResponse({'code':113,'result':'用户不存在'})
      else:
        base_data = imagecontent.split(',')[1]
        imageType = 'BASE64'
        groupIdList = 'usergroup'
        # 加入可选参数
        options = {}
        options['max_user_num'] = 1
        options['quality_control'] = 'NORMAL'
        options['liveness_control'] = 'LOW'
        # options['user_id'] = mobile
        result = AppConfig.client.search(base_data,imageType,groupIdList,options)
        print(result)
        error_code = result['error_code']
        try:
          user_id = result['result']['user_list'][0]['user_id']
          score = result['result']['user_list'][0]['score']
          if isinstance(error_code,int) and error_code == 0 and user_id == mobile and score >= 90: 
            request.session['mobile'] = mobile
            return JsonResponse({'code':200,'result':'快速登录成功'})
          else:
            error = ErrorCode().getErrorInfo(error_code)
            return JsonResponse({'result':'{}'.format(error)})
        except:
          error = ErrorCode().getErrorInfo(error_code)
          return JsonResponse({'result':'{}'.format(error)})
