获取位置信息步骤

1. 申请服务号认证

只有通过认证的服务号,才能够获取访问微信高级服务的权限。

2. 开启用户位置信息获取功能

开发者中心 -> 获取用户地理位置

3. weiPHP地理位置信息消息处理。

1. 配置微信服务号开发接口


微信服务器将会把用户与微信之间的交互事件消息,通过此接口推送给SP服务器。

2. 在WeixinController的IndexAction中处理location消息。

将xml消息转化为php数组,然后取出经纬度信息,以备使用。

$content = file_get_contents ( 'php://input' );
$data = new \SimpleXMLElement ( $content );
foreach ( $data as $key => $value ) {
    $this->data [$key] = strval ( $value );
}
// to use data["longitude"]; data["latitude"].
Copy after login
