Facebook的webhook页面 [英] Facebook webhook for pages

问题描述

我在一个页面上有管理员访问权限，我已经在我的网站上创建了Facebook应用程序并创建并验证了webhook。

问题是我无法获得任何我的行动后从Facebook的数据。我创建了页面和用户webhook，然后我创建了php脚本，将随时记录facebook尝试到达该页面。现在我可以看到Facebook正在调用该页面，但是我无法从该通话中获取任何数据。我已经打印了POST的内容，但它给了我1的价值。

此外，没有配置可以设置我需要跟踪的Facebook页面。我如何设置？

解决方案

我已经打印了POST的内容，但它给我的价值1。

Facebook不会将数据作为正常POST请求发送，它直接发送JSON。因此PHP不会填充$ _POST - 您需要直接读取原始的响应正文，然后解码。

file_get_contents（'php：/ / input'），然后 json_decode 。

另外，没有配置，我可以设置哪个Facebook页面我需要跟踪。如何设置？

您需要将您的应用程序订阅页面以接收更新，请参阅 https://developers.facebook.com/docs/graph-api/reference/page/subscribed_apps

I have admin access on one page, I have created facebook app and created and verified webhook on my website.

The problem is that I can't get any data from facebook after my action. I created page and user webhook, then I created php script which will log any time facebook tries to reach that page. Now I can see facebook is calling that page, but I can't get any data from that call. I have printed content of POST but it is giving me value "1".

Also, there is no configuration with which I can set which facebook page I need to track. How can I set it?

解决方案

I have printed content of POST but it is giving me value "1".

Facebook does not send the data as a "normal" POST request, it sends JSON directly. Therefor PHP will not populate $_POST – you need to read the raw response body directly, and then decode it.

file_get_contents('php://input'), and then json_decode.

Also, there is no configuration with which I can set which facebook page I need to track. How can I set it?

You need to subscribe your app to the page to receive updates, see https://developers.facebook.com/docs/graph-api/reference/page/subscribed_apps
