Question

当我从浏览器发出以下请求时，它可以正常工作。

https://graph.facebook.com/app?access_token=<a valid token>

但是，从我的代码完成后，同样的调用失败并出现以下错误，对于在浏览器中工作的完全相同的令牌。

2 * Client out-bound request
2 > GET https://graph.facebook.com/app?access_token=<the fb token>
2 * Client in-bound response
2 < 400
2 < Content-Type: text/javascript; charset=UTF-8
2 < WWW-Authenticate: OAuth "Facebook Platform" "invalid_request" "Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api"
2 < Access-Control-Allow-Origin: *

{"error":{"message":"Unsupported get request. Please read the Graph API documentation at https:\/\/developers.facebook.com\/docs\/graph-api","type":"GraphMethodException","code":100}}

进行此调用的客户端代码是： -

ClientResponse r = httpClient.resource("https://graph.facebook.com/app")
        .queryParam("access_token", fbAccessToken).accept(MediaType.APPLICATION_JSON)
        .get(ClientResponse.class);
FBAccessTokenResponse res = r.getEntity(FBAccessTokenResponse.class);
return res;

另一个有趣的事实是，如果fb令牌适合我（应用程序开发人员）或少数FB测试用户，则应用程序代码可以正常工作。对于其他实际用户，仅对我的应用程序失败并显示此错误。

为什么我从我的应用程序调用时从Graph api获取invalid_request？
