首先,在静态页面中,添加微信的配置文件,通过js获取

<script type="text/javascript">

wx.config({

debug: false,

appId: '{$signPackage.appId}',

timestamp: '{$signPackage.timestamp}',

nonceStr: '{$signPackage.nonceStr}',

signature: '{$signPackage.signature}',

jsApiList: [

// 所有要调用的 API 都要加到这个列表中

'checkJsApi',

'openLocation',

'getLocation',

'scanQRCode'

]

});

wx.ready(function () {

$('#scan').click(function(){

wx.scanQRCode({

needResult: 0,

});

});

wx.checkJsApi({

jsApiList: [

'getLocation'

],

success: function (res) {

if (res.checkResult.getLocation == false)

{

alert('你的微信版本太低,不支持微信JS接口,请升级到最新的微信版本!');

return;

}

}

});

wx.getLocation({

success: function (res) {

　　 var latitude = res.latitude; // 纬度,浮点数,范围为90 ~ -90

var longitude = res.longitude; // 经度,浮点数,范围为180 ~ -180.

var geoconv = 'http://api.map.baidu.com/geoconv/v1/?callback=coordinateTransformation&coords=' + longitude + ',' + latitude + '&from=1&to=5&ak=5BFNbSgnVF5g2O72NpvTDxFm';

var script = document.createElement('script');

script.src = geoconv;

document.head.appendChild(script);

},

cancel: function (res) {

alert('用户拒绝授权获取地理位置');

}

});

});

function coordinateTransformation(data)

{

var LATLNG = data.result[0].y + ',' + data.result[0].x;

var url = 'http://api.map.baidu.com/geocoder/v2/?callback=getCurrentLocation&ak=5BFNbSgnVF5g2O72NpvTDxFm&location=' + LATLNG + '&output=json&pois=1';

var script = document.createElement('script');

script.src = url;

document.head.appendChild(script);

}

function getCurrentLocation(data)

{

if(data.status === 0)

{

var address = data.result.formatted_address,

x = data.result.location.lng,

y = data.result.location.lat,

city = data.result.addressComponent.city,

street = data.result.addressComponent.street || data.result.formatted_address,

reqData = 'street=' + address + '&name=' + street + '&lng=' + x + '&lat=' + y + '&city=' + city;

var url = "{:U('Index/savePosition')}";

$.getJSON(url,{'name':street,'lng':x,'lat': y,'city':city},function(data)

{

if(data.returnCode) { }

});

}

}

</script>

其次,在控制器中接收ajax传递的地理坐标,然后保留到session中

public function savePosition()

{

$city = II('get.city','','trim');

$addr = II('get.name','','trim');

$lng = II('get.lng','','trim');

$lat = II('get.lat','','trim');

$myLocation = array(

'city' =>$city,

'addr' =>$addr,

'lng' =>$lng,

'lat' =>$lat,

);

$_SESSION['MyLocation'] = $myLocation;

$data['returnCode'] = 1;

$data['returnInfo'] = '获取位置成功!';

$this->ajaxReturn($data);

return;

}

注：用的是thinkphp框架,II是自定义的办法,获取get或post传递的值,和 I 函数一样.
