调用微信定位功能 lat _ lng php方法
{:wx_jssdk_config("false")} //最主要的这一句 没有这一句在微信浏览器里是无法调用的定位功能的。下面有这个方法说明 <script> wx.ready(function(){ wx.getLocation({ type: 'wgs84', // 默认为wgs84的gps坐标,如果要返回直接给openLocation用的火星坐标,可传入'gcj02' 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 data = { "lat":latitude, "lng": longitude, }; // console.log(data); $.ajax({ url:'{:U("Index/lat_lng_add")}', type: "POST", data: data, success: function (data) {} }); } }) }); </script>
以下代码是需要放在function.php中的
/** * 直接生成微信jssdk_config * @echo string $jssdk Jssdk_config * @author 5heAtMin9 <sheatming@foxmail.com> */ function wx_jssdk_config($debug='true'){ $getSignPackage = wx_getSignPackage(); $jssdk = '<script src="https://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>'; $jssdk .= '<script> wx.config({ debug: '.$debug.', appId: "'.$getSignPackage['appId'].'", timestamp: "'.$getSignPackage['timestamp'].'", nonceStr: "'.$getSignPackage['nonceStr'].'", signature: "'.$getSignPackage['signature'].'", jsApiList: ["checkJsApi","onMenuShareTimeline","onMenuShareAppMessage","onMenuShareQQ", "onMenuShareWeibo","onMenuShareQZone","hideMenuItems","showMenuItems","hideAllNonBaseMenuItem","showAllNonBaseMenuItem","translateVoice","startRecord","stopRecord","onVoiceRecordEnd","playVoice","onVoicePlayEnd","pauseVoice","stopVoice","uploadVoice","downloadVoice","chooseImage","previewImage","uploadImage","downloadImage","getNetworkType","openLocation","getLocation","hideOptionMenu","showOptionMenu","closeWindow","scanQRCode","chooseWXPay","openProductSpecificView","addCard","chooseCard","openCard"], }); </script>'; echo $jssdk; } /** * Jssdk所需信息 * @return array $signPackage Jssdk所需信息 * @author 5heAtMin9 <sheatming@foxmail.com> */ function wx_getSignPackage() { $jsapiTicket = wx_getJsApiTicket(); // 注意 URL 一定要动态获取,不能 hardcode. $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?
