Facebook - “无法通过用户名查询用户"解决方案 [英] Facebook - "Cannot query users by their username" solution

问题描述

我正在开发一个安卓应用.我正在使用 HttpURLConnection 来获取 facebook 用户的个人资料图片.网址如下所示:

I am developing an android app. I was using a HttpURLConnection to get profile pictures of facebook users. The URL looks like this:

http://graph.facebook.com/?ids=username1,username2,username3&fields=picture&type=square

但是现在，由于 v2.2 不允许我获取未使用我的 Facebook 应用程序的用户的个人资料图片，因此会引发错误:

But now, since v2.2 doesn't let me to get profile pictures of users who are not using my facebook app, it throws an error:

{错误":{

  "message": "(#803) Cannot query users by their username (username1)",
  "type": "OAuthException",
  "code": 803    } }

我对使用Android 版 Facebook SDK"不感兴趣.假设我使用弹出式 webview 来授权我的 facebook 应用程序.什么网址会让我做同样的事情?有没有像这样的简单解决方案:

I am not interested in using "Facebook SDK for Android". Let's say I use a pop-up webview to authorize my facebook app. What url would let me do the same thing? Is there a simple solution like this:

graph.facebook.com/?app=APP-ID&ids=username1,username2&fields=picture

graph.facebook.com/?app=APP-ID&ids=username1,username2&fields=picture

推荐答案

从 API 的 v2.0 开始，您根本不应该使用用户名 - 这就是您不能再通过用户名查询用户的原因.访问用户数据的唯一方法是授权该用户并使用 /me 端点.

Since v2.0 of the API, you are not supposed to use usernames at all - and that´s why you can´t query users by their username anymore. The only way to get access to data of a user is by authorizing that user and using the /me endpoint.

主要规则:忘记未授权您的应用程序的用户，出于隐私原因，您不应获取这些用户的任何数据.

Main rule: Forget about users who did not authorize your App, you are not supposed to get any data of those for privacy reason.
