<!-- 關於拍攝圖片的大小 若是設置targetWidth: 520, targetHeight: 520，最終拍攝的圖片依然是長方形，只會把最大的設置爲520px,另外一個按比例顯示，如最終的圖片是（390*520px) -->

後臺使用wamp集成包 html

<?php

    }

//在使用move_uploaded_file時，路徑upload/，必定要先創建upload的文件夾，不然出錯

（1）打包老是出錯，按下面解決方法ok
Open plugins/cordova-plugin-barcode-scanner/plugin.xml and delete all records xmlns:android=""
Open platforms/android/android.json and delete all xmlns:android=\"\"
Do the same in platforms/android/AndroidManifest.xmljava

（2）alert scanning failed:write settings:false，把targetSdkVersion從原來的25改爲22
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />android
