透过Facebook Messenger API：活动访问令牌必须用于查询当前用户

Question

我正在关注的发展莅临指导信息：https://developers.facebook.com/docs/messenger-platform/quickstart

我设置我的服务器和网络挂接。当我尝试做一个POST请求到Facebook的图形API，我得到如下回应：

{"response":{"statusCode":400,"content":"{\"error\":{\"message\":\"An active access token must be used to query information about the current user.\",\"type\":\"OAuthException\",\"code\":2500,\"fbtrace_id\":\"GHWSIH8OBGm\"}}","headers":{"www-authenticate":"OAuth \"Facebook Platform\" \"invalid_request\" \"An active access token must be used to query information about the current user.\"","access-control-allow-origin":"*","pragma":"no-cache","cache-control":"no-store","facebook-api-version":"v2.6","expires":"Sat, 01 Jan 2000 00:00:00 GMT","content-type":"text/javascript; charset=UTF-8","x-fb-trace-id":"GHWSIH8OBGm","x-fb-rev":"2296043","vary":"Accept-Encoding","x-fb-debug":"4KebPKo5T+Al/88Z7DWtZ8ROawIB3cZFLp65OVi/soTB6hOHstvXox5czalYj45FdI+2r+MQwNh9PHur5uGSbQ==","date":"Wed, 20 Apr 2016 23:45:26 GMT","transfer-encoding":"chunked","connection":"keep-alive"},"data":{"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500,"fbtrace_id":"GHWSIH8OBGm"}}}} 

我使用的是由应用页面提供的页面访问令牌。我使用fb令牌验证器来验证令牌未过期。

我感谢任何帮助。

Answer 1

错误消息显示您正试图查询有关当前用户与您的char bot进行通信的信息。 供应用户信息的API终点是：

https://graph.facebook.com/v2.6/USER_ID_HERE?fields=first_name,last_name,profile_pic&access_token=PAGE_ACCESS_TOKEN_HERE 

而且按照文件，你需要做一个GET请求（不POST）为此点。

您可以使用用户个人资料API中的个人姓名或个人资料照片个性化对话。为了获得这些信息，请向https://graph.facebook.com/v2.6/？fields = first_name，last_name，profile_pic发送GET请求& access_token =。在发送API参考中阅读更多详细信息。 https://developers.facebook.com/docs/messenger-platform/implementation#user_profile_api

尝试使用值“承载PAGE_ACCESS_TOKEN”设置“授权”头，而不是“的access_token：PAGE_ACCESS_TOKEN”
