How do I get the App Access Token via the Facebook PHP SDK?
提问by Boehmi
I'm trying to retrieve the app access token of my app in order to post notifications, but for some reason, it doesn't work. Here's the code:
我正在尝试检索我的应用程序的应用程序访问令牌以发布通知，但由于某种原因，它不起作用。这是代码：
$AppParams = array(
'client_id' => 'myclientid',
'&client_secret' => 'myclientsecret',
'&grant_type' =>'client_credentials'
);
$AppToken = $facebook->api('oauth/access_token?', 'GET', $AppParams);
I also replaced the first part with the full oauth/accesstoken link, but then it returns me general information about oauth and their facebook page, which I do not want. I did nearly the same thing in C# and there it works.
我还用完整的 oauth/accesstoken 链接替换了第一部分，但随后它返回了我不想要的有关 oauth 及其 Facebook 页面的一般信息。我在 C# 中做了几乎相同的事情，并且在那里工作。

You don't really have to request an application access token. You can simply assemble one yourself.
您实际上不必请求应用程序访问令牌。您可以简单地自己组装一个。
An application access token is formatted like this:
应用程序访问令牌的格式如下：
app_id|app_secret
That's the application's id, a pipe character |and the application secret.
那是应用程序的 id、管道字符|和应用程序机密。
Make sure that this app token is not accessible to your users! Only use and reference it on the serverside - never pass this to the client. For more info, check out the last few sentences in the relevant documentation.
确保您的用户无法访问此应用程序令牌！仅在服务器端使用和引用它 - 永远不要将其传递给客户端。有关更多信息，请查看相关文档中的最后几句话。

With version 5 of the SDK you can get the access token with the accessToken()method of a FacebookAppinstance. If you have a Facebookinstance (as you normally would) you can get it like this:
使用 SDK 的第 5 版，您可以accessToken()使用FacebookApp实例的方法获取访问令牌。如果你有一个Facebook实例（就像你通常那样），你可以像这样得到它：
$fb->getApp()->getAccessToken()
When I want to use my own app's access token I'm instantiating the API like this. I don't know if there's a cleaner way.
当我想使用我自己的应用程序的访问令牌时，我正在像这样实例化 API。不知道有没有更干净的方法。
$fb = new \Facebook\Facebook([
'default_graph_version' => 'v2.8',
]);
$fb->setDefaultAccessToken($fb->getApp()->getAccessToken());

Replace -
代替 -
'&client_secret' => 'client_secret'
'&grant_type' => 'grant_type'
