微信小程式之刷臉登入

在camera.wxml中編寫程式碼如下:
<camera device-position="{{value}}" flash="off" binderror="error" style="width: 100%; height: 300px;"></camera> <switch checked bindchange="switch1change" style="margin-top:5px;"></switch> <button type="primary" bindtap="takePhoto" style="margin-top:5px;">刷臉登入</button> <view>預覽</view> <image mode="widthFix" src="{{src}}"></image>
在camera.js中編寫程式碼如下:
// pages/cream/cream.js Page({ /** * 頁面的初始資料 */ data: { value: '', src: '' }, takePhoto() { const ctx = wx.createCameraContext() ctx.takePhoto({ quality: 'high', success: (res) => { this.setData({ src: res.tempImagePath }) wx.showLoading({ title: '正在核驗身份.....', }) this.setData({ logindisabled: true }); wx.uploadFile({ url: '', filePath: res.tempImagePath, name: 'file', success: (res) => { wx.hideLoading(); this.setData({ logindisabled: false }); var data = res.data console.log(data); wx.showModal({ title: '提示', content: data, showCancel: false }) } }) } }) }, error(e) { console.log(e.detail) }, switch1change: function (e) { console.log(e) if (e.detail.value) { this.setData({ value: 'back' }) } else { this.setData({ value: 'front' }) } }, })
這樣在微信小程式中就編寫成功了,然後在控制器中編寫程式碼如下:
這樣簡單的微信小程式刷臉認證就完成了//刷臉登入 public function login(){ $dir="./Uploads/temp/"; if (!file_exists($dir)) { mkdir($dir,0777,true); } $upload = new \Think\Upload();// 例項化上傳類 $upload->maxSize = 2048000 ;// 設定附件上傳大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 設定附件上傳型別 $upload->rootPath = $dir; // 設定附件上傳根目錄 $upload->savePath = ''; // 設定附件上傳(子)目錄 $upload->autoSub=false; //上傳檔案 $info = $upload->uploadOne($_FILES['file']); if(!$info) {// 上傳錯誤提示錯誤資訊 return $this->ajaxReturn(array('error'=>true,'msg'=>$upload->getError()),JSON_UNESCAPED_UNICODE); }else{ // $this->ajaxReturn('上傳成功'); $file=$dir.$info['savepath'].$info['savename']; $image=base64_encode(file_get_contents($file)); $client=$this->face(); $options['liveness_control']='NORMAL'; $options['max_user_num']='1'; $ret=$client->search($image,'BASE64',$this->face_group(),$options); // echo json_encode($ret,JSON_UNESCAPED_UNICODE); // exit; if ($ret['error_code']==0) { $user=$ret['result']['user_list'][0]; $no=$user['user_id']; $score=$user['score']; if (!empty($no)) { $data=M('student')->field('no,name,sex')->where("no='{$no}'")->find(); if ($data) { $data['score']=$score; echo json_encode($data,JSON_UNESCAPED_UNICODE); exit; }else{ echo "本地資料庫沒有該學生,百度雲庫資訊:個人資訊:{$no},分值:{$score}"; } } }else{ echo "活體檢測失敗".json_encode($ret,JSON_UNESCAPED_UNICODE); } } }
