uniapp - 检查用户是否授权、如果拒绝授权提供提示框，用户可以在设置界面中打开权限

最近在用uniapp 开发微信小程序 vue + vuex + vue-cli3 + hbuilderx 

export function checkForAuthorization(scope){
    return new Promise((resolve,reject)=>{
        uni.getSetting({
            success(res) {
                console.log(res.authSetting)
                if (!res.authSetting[scope]) {
                    uni.authorize({
                        scope,
                        success() {
                            resolve()
                        },
                        fail() {
                            uni.hideLoading();
                            uni.showModal({
                                title: '温馨提示',
                                content: '您已拒绝授权，是否去设置打开？',
                                confirmText: "确认",
                                cancelText: "取消",
                                success: function(res) {
                                    // console.log(res);
                                    if (res.confirm) {
                                        uni.hideLoading();
                                        uni.openSetting({

                                                res.authSetting[scope] = true
                                                resolve()
                                            }
                                        });
                                    } else {
                                        reject({errMsg:'用户拒绝授权'})
                                    }
                                },
                                fail(res) {
                                    reject(res)
                                }
                            });
                     
                        }
                    })
                } else {
                    resolve()
                }
            },
