微信小程序getphonenumber的回调在开发者工具可以触发，但是打包以后就触发不了，有大佬知道为什么吗

                <button open-type="getPhoneNumber" @getphonenumber="getPhoneNumber"  
                    class="yellow-btn btn-text center"  
                    :class="{'activity-btn': _self.$uniApi.getType(roomInfo), 'activity-btn-one': !_self.$uniApi.getType(roomInfo)}"  
                    style="position: fixed; right: 0;  background-color: #4CD964;">拨打电话</button>

            getPhoneNumber(e) {  
                var _self = this;  
                // 弹窗申请获取手机号权限  
                if (e.detail.errMsg == 'getPhoneNumber:fail user deny') {  
                    console.log('用户拒绝提供手机号');  
                    uni.showToast({  
                        title: "无法获取信息,请允许后重试！",  
                        icon: 'none'  
                    })  
                } else {  
                    console.log('用户同意提供手机号');  
                    uni.request({  
                        url: "https://api.weixin.qq.com/sns/jscode2session",  
                        method: "GET",  
                        data: {  
                            appid: getApp().globalData.wxAppId,  
                            secret: getApp().globalData.wxAppSecret,  
                            js_code: _self.code,  
                        },  
                        success(cts) {  
                            // 请求成功  
                            //解密获得用户手机号  
                            let pc = new WXBizDataCrypt(getApp().globalData.wxAppId, cts.data.session_key);  
                            let data = pc.decryptData(e.detail.encryptedData, e.detail.iv);  
                            // //将用户手机号设置进全局  
                            // getApp().globalData.phoneNumber = data.phoneNumber;  
                            uni.setStorage({  
                                key: 'phoneNumber',  
                                data: data.phoneNumber,  
                            })  
                            _self.phoneNumber = data.phoneNumber;  
                            _self.callPhone();  
                        }  
                    });  
                }  

            },
