如果测试用户已经安装的应用程序与图形API [英] Test if user has application installed with Graph API

问题描述

什么是最新的方法来确定Fa​​cebook的用户已经安装的应用程序？我看到有一个安装字段的用户对象的权限连接，但是这需要一个的access_token进行测试。发生了什么事isAppUser？为什么这个网址说以下内容：

What is the most current method to determine if a Facebook User has installed an application? I see that there is an "installed" field on the "permissions" connection of a user object, but that requires an access_token to test. What happened to isAppUser and why does this URL say the following:

请使用图形API用户对象和GET / [UID]字段=安装
  检查如果用户已TOSed该应用程序。

Please use the Graph API User object and GET /[UID]?field=installed to check if a user is has TOSed that app.

引用的/ [UID]字段=安装什么都不做。

The referenced /[UID]?field=installed does nothing.

推荐答案

这是要求字段当为我工作 - 的文档显示为引用字段我认为这是不正确的，我会得到它的更新如果是这样的话：

This is working for me when asking for 'fields' - the docs appear to be referencing 'field' which I think is incorrect, I'll get it updated if that's the case:

例如

GET https://graph.facebook.com/me?fields=installed&access_token=<SNIPPED令牌GT;

返回：

{
   "installed": true,
   "id": "<SNIPPED ID>"
}

/我 A呼叫/权限可能是你想要在大多数情况下是什么，因为这也将显示授予您的应用程序扩展权限

A call to /me/permissions is probably what you want in most cases as this will also show the extended permissions granted to your app
