[agger21]

1.检测是否授权定位与引导授权

checkLocation(){
            var that = this;
            wx.getSetting({
                success: (res) => {
                    if (res.authSetting['scope.userLocation'] != undefined && res.authSetting['scope.userLocation'] != true) {//非初始化进入该页面,且未授权
                        wx.showModal({
                            title: '是否授权当前位置',
                            content: '需要获取您的地理位置，请确认授权，否则地图功能将无法使用',
                            success: function (res) {
                            if (res.cancel) {
                                console.log("1授权失败返回数据");
                            } else if (res.confirm) {
                                wx.setStorageSync('isChecked','yes')
                                //village_LBS(that);
                                wx.openSetting({
                                success: function (data) {
                                    console.log(data);
                                    if (data.authSetting["scope.userLocation"] == true) {
                                        //再次授权，调用getLocationt的API
                                        that.setLocation();
                                    }else{
                                    
                                    }
                                }
                                })
                            }
                            }
                        })
                    } else if (res.authSetting['scope.userLocation'] == undefined) {//初始化进入
                        that.setLocation();
                    }
                }
            })
        }

2.设置定位

        setLocation(){
            wx.getLocation({
                type: 'wgs84',
                success: function(res) {
                    console.log(res,'我的经纬度')
                    wx.setStorageSync("latitude",res.latitude)
                    wx.setStorageSync("longitude",res.longitude)
                }
            })
        }

3.点击分享按钮分享

  <button class='box newBtn' id="btn1" open-type='share' plain='true' >
         <text>分享</text>
   </button>

 onShareAppMessage(res) {
                if (res.from === 'button') {
                    let target_id = res.target.id;
                    //id为btn1的button触发
                    if (target_id === "btn1") {
                        return {
                            title: 'btn1转发一',
                            path: 'pages/list/detail?id=35',
                            success: function(res) {
                                // 转发成功
                            },
                            fail: function(res) {
                                // 转发失败
                            }
                        }
                    //id为btn2的button触发
                    }
                    return {
                        title: '美食地图',
                        path: 'pages/list/detail?id='+this.shopId
                    }
                }
            },
