login接口：
public function login(){ // 上传文件路径 $dir = "./Uploads/temp/"; if(!file_exists($dir)){ mkdir($dir,0777,true); } $upload = new \Think\Upload(); $upload->maxSize = 2048000 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->savepath = ''; $upload->autoSub = false; $upload->rootPath = $dir; // 设置附件上传根目录 // 上传单个文件 $info = $upload->uploadOne($_FILES['file']); if(!$info) {// 上传错误提示错误信息 echo json_encode(array('error'=>true,'msg'=>$upload->getError()),JSON_UNESCAPED_UNICODE); }else{// 上传成功 获取上传文件信息 $file = $dir . $info['savepath'].$info['savename']; $image = base64_encode(file_get_contents($file)); $client = $this->init_face(); $options['liveness_control'] = 'NORMAL'; $options['max_user_num'] = '1'; $ret = $client->search($image,'BASE64','student',$options); // echo json_encode($ret,JSON_UNESCAPED_UNICODE); // exit; if($ret['error_code']==0){ $user = $ret['result']['user_list'][0]; $no = $user['user_id']; $score = $user['score']; if($score>=95){ $data = M('student')->where("no = '{$no}'")->find(); $data['score'] = $score; // $data['name'] = json_decode($data['name'],true); // $data['sex'] = json_decode($data['sex'],true); echo '识别成功' . json_encode($data,JSON_UNESCAPED_UNICODE); }else{ echo '识别失败' . $data['score']; } } } }
然后进行前台设计
<camera device-position="{{device?'back':'front'}}" flash="off" binderror="error" style="width: 100%; height: 300px;"></camera> <view class="weui-cells__title" >开关</view> <view class="weui-cells weui-cells_after-title"> <view class="weui-cell weui-cell_switch"> <view class="weui-cell__bd">切换摄像头</view> <view class="weui-cell__ft" > <switch bindtap="devicePosition" /> </view> </view> </view> <button type="primary" bindtap="takePhoto">刷脸登录</button>
我们还可以控制相机的前后镜头
devicePosition() { this.setData({ device: !this.data.device, }) console.log("当前相机摄像头为:", this.data.device ? "后置" : "前置"); camera() { let { ctx, type, startRecord } = this.data; }, data: { src: null, },
调用接口：
takePhoto() { const ctx = wx.createCameraContext() ctx.takePhoto({ quality: 'high', success: (res) => { this.setData({ src: res.tempImagePath }) console.log(res) wx.uploadFile({ url: '', //仅为示例，非真实的接口地址 filePath: this.data.src, name: 'file', formData: { }, success: function (res) { // var data = res.data // var json = JSON.parse(data) console.log(res) wx.showModal({ title: "提示", content: res.data, showCancel: false, confirmText: "确定"}) } }) } }) },
