某些游戏的图像无法加载SteamAPI

Question

搜索时，我会得到所有游戏的列表，然后我在列表中通过AppID搜索游戏。有的游戏画面正常显示，有的则缺失。 当空图像时，我得到

Error when receiving data for a game with AppID 1237970;
 1
{"1237970":{"success":false}}

同时，如果我用这个AppID手动去浏览器请求，就会显示信息。 还有，有一次偶然看不清游戏画面是如何正常出现的。

我尝试使用Steam不同地区的API密钥。

问题解决了——都是关于区域和VPN的。无论 API 密钥位于哪个区域，连接本身都必须来自游戏显示的区域。代码可能不专业，但它是正确且有效的。
