如何通过 API 让 Facebook 应用程序访问 Facebook 页面？

Question

As we all know, inside the Facebook for Developers interface, you can add Facebook Pages to a Facebook App as in the picture below and generate the Page Access Token .众所周知，在Facebook for Developers界面中，您可以将 Facebook Pages 添加到 Facebook App 中，如下图所示，并生成Page Access Token 。

I'm trying to do this programmatically via the API requests.我正在尝试通过 API 请求以编程方式执行此操作。 Unfortunately, I did not find in the documentation of the request how to do this.不幸的是，我没有在请求的文档中找到如何执行此操作。

What have I done so far?到目前为止我做了什么？

I can get the User ID and User Access Token via Facebook Login ( Documentation ).我可以通过Facebook Login （文档）获取User ID和User Access Token 。
I can get the list of Facebook Pages that a person owns.我可以得到一个人拥有的Facebook Pages列表。 In the response, I have the Page ID and the Page Access Token ( Documentation ).在响应中，我有Page ID和Page Access Token （文档）。
I have the Facebook app that is in development mode.我有处于开发模式的 Facebook 应用程序。 That app has App ID and App Secret .该应用程序具有App ID和App Secret 。 With these values, I can get the App Access Token ( Documentation ).使用这些值，我可以获得App Access Token （文档）。
I can set Webhook to the Facebook App with App ID and App Access Token ( Documentation ).我可以使用App ID和App Access Token （文档）将Webhook设置为 Facebook 应用。
I can set the Webhook Subscriptions Fields for my Facebook App ( Documentation ).我可以为我的 Facebook 应用程序（文档）设置Webhook Subscriptions Fields 。

Question: What kind of API request should I use to add a Facebook Page to the Facebook App?问：我应该使用哪种 API 请求将 Facebook 页面添加到 Facebook 应用程序？

The list of my requests:我的请求清单：

I take Page ID and Page Access Token with this GET request cause this request returns the list of Facebook Pages that a person owns:我使用此 GET 请求获取Page ID和Page Access Token ，因为此请求返回一个人拥有的Facebook Pages列表：

https://graph.facebook.com/v9.0/{user-id}/accounts?access_token={user-access-token} https://graph.facebook.com/v9.0/{user-id}/accounts?access_token={user-access-token}

I set the Webhook in my Facebook App with this POST request:我使用以下POST请求在我的Facebook App中设置了Webhook ：

https://graph.facebook.com/v9.0/{app-id}/subscriptions?access_token={app-access-token}&callback_url={url-address}&verify_token={verify-token}&object=page&include_values=true https://graph.facebook.com/v9.0/{app-id}/subscriptions?access_token={app-access-token}&callback_url={url-address}&verify_token={verify-token}&object=

It successfully works and I see this Webhook in the "Webhooks" block of the Dashboard interface.它成功运行，我在Dashboard界面的“Webhooks”块中看到了这个 Webhook。

Then I make this POST request to set Webhook Subscriptions Fields :然后我发出这个 POST 请求来设置Webhook Subscriptions Fields ：

https://graph.facebook.com/{page-id}/subscribed_apps?subscribed_fields=messages,messaging_postbacks,messaging_optins,message_deliveries,message_reads,messaging_payments,messaging_pre_checkouts,messaging_checkout_updates,messaging_account_linking,messaging_referrals,message_echoes,messaging_game_plays,standby,messaging_handovers,messaging_policy_enforcement,message_reactions,inbox_labels&access_token={page-access-token} https://graph.facebook.com/{page-id}/subscribed_apps?subscribed_fields=messages,messaging_postbacks,messaging_optins,message_deliveries,message_reads,messaging_payments,messaging_pre_checkouts,messaging_checkout_updates,messaging_account_linking,messaging_referrals,message_echoes,messaging_game_plays,standby,messaging_handovers,messaging_policy_enforcement, message_reactions,inbox_labels&access_token={page-access-token}

In this request, I use Page ID and Page Access Token from the first step.在此请求中，我使用第一步中的Page ID和Page Access Token 。

Unfortunately, I have such an error message:不幸的是，我有这样一个错误信息：

To subscribe to the messages field, one of these permissions is needed: pages_messaging要订阅消息字段，需要以下权限之一： pages_messaging

I've been following down a similar rabbit hole.我一直在跟踪一个类似的兔子洞。 Indeed, Facebook documentation is confusing, but it ended up being pretty simple.确实，Facebook 文档令人困惑，但它最终变得非常简单。 Here is the modified Facebook Login example , which gets page access token and then adds necessary webhook subscriptions for page messaging.这是修改后的Facebook 登录示例，它获取页面访问令牌，然后为页面消息添加必要的 webhook 订阅。 After you've run it, you will see the page is added to the App settings with the requested webhook subscriptions.运行后，您将看到该页面已添加到带有请求的 webhook 订阅的应用程序设置中。 Hope it helps希望能帮助到你
