前端-微信小程序打开相机后，左右划关闭相机不触发fail回调，只触发complete回调

[agger21]

如果一定要左右滑动关闭，采用参数控制来实现；

getCamera(){
            let theClose = true;
                wx.scanCode({
                    onlyFromCamera: true,
                    success: (res) => {
                        theClose = false;

                    },
                    
                    fail:(res)=>{
                        console.log(res,'fail')
                    },
                    complete:(res)=>{
                         setTimeout(() => {
                            if(theClose){
                              
                            }
                        }, 500);
                    }
                })
