如何获取没有应用程序或应用程序秘密的页面的Facebook访问令牌 [英] How to get a Facebook access token for a page with no app or app secret

问题描述

我正试图从Facebook页面自动显示墙上的其他网站。我可以使用Graph API Explorer来手动获取。当我在代码中使用生成的令牌一切都很好。问题是令牌快速到期。每天多次获取新代码是不实际的。我知道有一种方式可以通过PHP方式请求访问令牌 - 在我的情况下，通过PHP，但所有的示例都要求一个应用程序的秘密。因为这是一个页面而不是一个应用程序，所以没有秘密。

我已经尝试过：

https：/ /graph.facebook.com/oauth/authorize?type=user_agent&client_id=MY_CLIENT_ID&redirect_uri=http%3A%2F%2FMY_SITE_URL&scope=user_status

我收到的是这样的：

{
error：{
message：验证应用程序时出错，无法获取应用信息由于系统错误，
type：OAuthException，
code：101
}
}

$ b $我尝试使用Fiddler截取Graph API资源管理器中的调用，以查看我在代码文件中需要什么，但没有任何运气。

解决方案

对于非私有（public）的图形对象，可以使用app_id作为access_token。

您的app_id不会更改，因此您不必更新它。问题是你的墙壁内容？

如果是这样，您可以轻松地使用 app_id 来完成此操作，而无需每次请求访问令牌。 p>

但是，为了拥有一个app_id，您需要在Facebook上使用Facebook开发者帐户创建一个应用程序。据我所知，没有一种匿名方式向Graph API请求，

I am trying to automatically display wall posts from a Facebook page another website. I can use the Graph API explorer to get one manually. When I use the generated token in my code all is well. The problem is the tokens expire quickly. It just isn't practical to get a new code several times a day. I know there is a way to request an access token programatically - in my case via PHP, but all the examples call for an app secret. Since this is a page and not an app, there is no secret.

I have tried this:

https://graph.facebook.com/oauth/authorize?type=user_agent&client_id=MY_CLIENT_ID&redirect_uri=http%3A%2F%2FMY_SITE_URL&scope=user_status

What I get back is this:

{ "error": { "message": "Error validating application. Cannot get application info due to a system error.", "type": "OAuthException", "code": 101 } }

I have tried using Fiddler to intercept the call from the Graph API explorer to see what I need in my code file, but haven't had any luck.

解决方案

For graph objects that are not private (public) you can use your app_id as an access_token.

Your app_id never changes so you don't ever have to renew it. The question is is the wall content yours?

If so you can easily use your app_id to accomplish this without having to request an access token everytime.

However, in order to have an app_id you need to create an application on facebook with a facebook developer account. As far as I understand there isnt a way to anonymously make request to the Graph API,
