如何从Facebook messenger平台发送位置？

Question

有一种方法可以将我的位置从移动客户端发送到facebook-messenger，但我如何从机器人发送位置？(messenger platform api)

当我尝试从机器人发送一个类似的结构时，我得到了一个错误：(#100) Unsupported attachment type

有没有办法从机器人上发送我的位置？

收到的机器人消息示例：

{
   "object": "page",
   "entry": [{
       "id": "1719442148306048",
       "time": 1466780344978,
       "messaging": [{
           "sender": {"id": "123456789"},
           "recipient": {"id": "987654321"},
           "timestamp": 1466780344847,
           "message": {
               "mid": "mid.12345698875:c80066d69b6cee1779",
               "seq": 65,
               "attachments": [{
                   "title": "Dmitry's Location",
                   "url": "Link to bing.com through facebook redirect"
                   "type": "location",
                   "payload": {"coordinates": {"lat": 55, "long": 37}}
               }]
           }
       }]
   }]
}

我尝试发送带有附件的邮件，如下所示：

               "attachment": {
                   "type": "location",
                   "payload": {"coordinates": {"lat": 55, "long": 37}}
               }

有一种解决方法。我们可以发送带有静态地图图像和url的通用模板到动态。对于谷歌原生地图应用，我们可以使用address http://maps.apple.com/maps (它使用相同的参数将所有非iOS用户重定向到iOS地图)。在安卓系统上，它可以打开谷歌地图应用。

{
    "recipient": {"id": "132456"},
    "message": {
        "attachment": {
            "type": "template",
            "payload": {
                "template_type": "generic",
                "elements": {
                    "element": {
                        "title": "Your current location",
                        "image_url": "https:\/\/maps.googleapis.com\/maps\/api\/staticmap?size=764x400&center="+lat+","+long+"&zoom=25&markers="+lat+","+long,
                        "item_url": "http:\/\/maps.apple.com\/maps?q="+lat+","+long+"&z=16"
                    }
                }
            }
        }
    }
}

德米特里，谢谢你的攻击！FB API略有变化，以下是我在有效负载部分的工作：

    payload = dict()
    payload['type'] = 'template'
    payload['text'] = dict(
        template_type="generic",
        elements=[
            dict(
                title='{venue} location',
                # subtitle='Test',
                image_url="https://maps.googleapis.com/maps/api/staticmap?size=764x400&center=" + lat + "," + long +
                          "&zoom=15&markers=" + lat + "," + long,  
                default_action=dict(
                    type="web_url",
                    url="http://maps.apple.com/maps?q=" + venue + "&ll=" + lat + "," + long +
                        "&z=15"
                )
            )  # buttons=[])
        ]
    )
