<!-- 关于拍摄图片的大小 若是设置targetWidth: 520, targetHeight: 520，最终拍摄的图片依然是长方形，只会把最大的设置为520px,另外一个按比例显示，如最终的图片是（390*520px) -->

后台使用wamp集成包 html

//在使用move_uploaded_file时，路径upload/，必定要先创建upload的文件夹，不然出错

（1）打包老是出错，按下面解决方法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从原来的25改为22
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />android
