判断权限和结果的两个函数
//判断图片权限
isAuth: function (res) {
let that = this;
wx.getSetting({
success(res) {
if (!res.authSetting['scope.writePhotosAlbum']) {
wx.authorize({
scope: 'scope.writePhotosAlbum',
success(res) {
}
})
} else {
that.setData({ isSaveImageToPhotosAlbum: true })
}
},
})
},
//判断授权结果
authOpen: function (res) {
let that = this;
if (res.detail.authSetting['scope.writePhotosAlbum']) {
that.setData({ isSaveImageToPhotosAlbum: true })
} else {
that.setData({ isSaveImageToPhotosAlbum: false })
}
},
