facebook-graph-api - 使用 curl 查询图形 API

Question

我想检查一下如何处理access_token .所以，我使用 curl执行以下查询:

curl -X POST https://graph.facebook.com/oauth/access_token -d "client_id=<appId>&client_secret=<secret>&grant_type=client_credentials&redirect_uri="

它返回 access_token 的值.

然后，我想获取我的 friend 列表:

curl -X POST https://graph.facebook.com/me/friends -d "access_token=<token>"

它返回此错误:

{"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}

任何提示？

简单的方法是使用图形 API 资源管理器，去那里使用您的 facebook 开发者帐户获取和访问 token :

Generate a Basic User Access Token

When you get to building your own app, you'll need to learn about access tokens and how to generate them using Facebook Login, but for now, we can get one really quickly through the Graph API Explorer:

Click on the Get Token button in the top right of the Explorer.
Choose the option Get User Access Token.
In the following dialog don't check any boxes, just click the blue Get Access Token button.
You'll see a Facebook Login Dialog, click **OK" here to proceed.

您可以将图形 api 资源管理器用作 curl，但如果您想使用真正的 curl 来尝试它，对于最新的 api v2.8，sintaxis 如下所示:

curl -i -H 'Authorization: Bearer YOUR_ACCES_TOKEN' -XGET 'https://graph.facebook.com/v2.8/me'

就我而言:

toni@MBP-de-Antonio  ~  curl -i -H 'Authorization: Bearer MY-ACCES_TOKEN' -XGET 'https://graph.facebook.com/v2.8/me'
