小程序引导用户授权的思路及项目实现方法（附代码）

<button>允许用户授权</button>

// 查看是否授权,保存授权状态
    wx.getSetting({
        success: function(res) {
            if (res.authSetting['scope.userInfo']) {
                wx.setStorageSync('isAuthorize', 'true');
                wx.getUserInfo({
                    success: function(res) {
                        wx.setStorageSync('userInfo', res.rawData);
                    }
                })
            } else {
                wx.setStorageSync('isAuthorize', 'false');
            }
        }
    })

<!-- 小程序授权组件 -->
<authorize></authorize>

// 已授权隐藏弹框，未授权显示弹框
this.authorize = this.selectComponent("#authorize");
if (wx.getStorageSync('isAuthorize')=='true'){
    this.authorize.hideDialog()
}

"usingComponents": {
    "authorize": "自定义授权组件的路径"
}

/*authorize.js*/
Component({
    options: {
        multipleSlots: true
    },

    data: {
        isHide: false,
        canIUse: wx.canIUse('button.open-type.getUserInfo')
    },

    methods: {

        //隐藏弹框
        hideDialog() {
            this.setData({
                isHide: true
            })
        },
        // 授权信息保存
        bindGetUserInfo(e){
            wx.setStorageSync('isAuthorize', 'true');
            wx.setStorageSync('userInfo', JSON.stringify(e.detail.userInfo));
            this.hideDialog()
        }

    }
})
