Facebook Messenger Bot - 列表模板的无效 URL 按钮字段

Question

我一直在努力向用户发送包含一些数据的列表。我正在关注 facebook's doc 来设置我的请求负载。但是，我收到以下错误：

{'error': {
    'message': '(#100) Invalid URL button fields provided. Please check documentation for details.', 
    'type': 'OAuthException', 
    'code': 100, 
     'error_subcode': 2018125, 'fbtrace_id': 'GZFFcM+j5e/'}}

这是我的 JSON 有效载荷：

{'recipient': {'id': 'MY_MESSENGER_ID'}, 
 'message':
    {'attachment': 
       {'type': 'template', 
        'payload': 
          {'template_type': 'list', 
           'top_element_style': 'compact', 
            'elements': 
                [{'title': 'Hello 1', 'subtitle': 'Subtitle 1', 
                 'buttons': 
                    [{'title': 'View', 'type': 'web_url', 
                      'url': 'https://www.medium.com/', 
                      'messenger_extensions': 'false', 
                      'webview_height_ratio': 'full',
                      'fallback_url': 'https://www.medium.com/'}],
                 'default_action': 
                    {'title': 'View', 'type': 'web_url', 
                    'url': 'https://www.medium.com/',
                    'messenger_extensions': 'false', 
                    'webview_height_ratio': 'full', 
                    'fallback_url': 'https://www.medium.com/'}}, 
              {'title': 'Hello 2', 'subtitle': 'Subtitle 2', 
               'image_url': 'https://cdn-images-1.medium.com/1*Vkf6A8Mb0wBoL3Fw1u0paA.jpeg', 
               'buttons': 
                      [{'title': 'View', 'type': 'web_url', 
                         'url': 'https://www.medium.com/',
                         'messenger_extensions': 'false', 
                         'webview_height_ratio': 'full', 
                         'fallback_url': 'https://www.medium.com/'}], 
               'default_action': 
                      {'title': 'View', 'type': 'web_url', 
                       'url': 'https://www.medium.com/', 
                       'messenger_extensions': 'false',
                       'webview_height_ratio': 'full', 
                       'fallback_url': 'https://www.medium.com/'}}]}}}}

我检查过，重新检查过多次。另外，我已经从文档中发送了 facebook 的示例 json，但我得到了相同的回复。请看一看，让我知道我卡在哪里！

这是我的结局url： “https://graph.facebook.com/v2.6/me/messages?access_token=”

提前致谢！

您的请求有两个问题：

对于default_action，只有在messenger_extensions:true

fallback_url

default_action 不能有 title 道具。

试试这个：

{ "recipient"：{ "id": "{{PSID}}" }, "message"：{ "attachment"：{ "type": "template", "payload"：{ "template_type": "list", "top_element_style": "compact", "elements"：[{ "title": "Hello 1", "subtitle": "Subtitle 1", "buttons"：[{ "title": "View", "type": "web_url", "url": "<a href="https://www.medium.com/" rel="nofollow noreferrer">https://www.medium.com/</a>", "messenger_extensions": "false", "webview_height_ratio": "full" }], "default_action"：{ "type": "web_url", "url": "<a href="https://www.medium.com/" rel="nofollow noreferrer">https://www.medium.com/</a>", "messenger_extensions": "false", "webview_height_ratio": "full" } }, { "title": "Hello 2", "subtitle": "Subtitle 2", "image_url": "<a href="https://cdn-images-1.medium.com/1" rel="nofollow noreferrer">https://cdn-images-1.medium.com/1</a>*Vkf6A8Mb0wBoL3Fw1u0paA.jpeg", "buttons"：[{ "title": "View", "type": "web_url", "url": "<a href="https://www.medium.com/" rel="nofollow noreferrer">https://www.medium.com/</a>", "messenger_extensions": "false", "webview_height_ratio": "full" }], "default_action"：{ "type": "web_url", "url": "<a href="https://www.medium.com/" rel="nofollow noreferrer">https://www.medium.com/</a>", "messenger_extensions": "false", "webview_height_ratio": "full" } } ] } } } }
