我正在从 Parse 的后端迁移到 Heroku 和 MongoDB 上的 Parse-server。
有了这个新的后端更改，我的一切工作都很顺利(包括加载 PFFiles)，但是，我现在在添加 FACEBOOK_APP_ID 参数后遇到错误，但是，这可能不是原因。
每当我尝试加载 PFFile(图片)时，我都会在日志中收到以下消息:

虽然我可以禁用 ATS，但这是一种不好的做法，我更愿意使用 HTTPS。此外，错误代码为“100”，但我可以连接到我的服务器并检索对象和用户数据。
如何在保留 HTTPS 的同时使用 Parse-server 加载 PFFiles？
最佳答案
最好的办法是为您的 API 获取 SSL 证书，但如果这不可能，暂时的解决方法是将您的域添加为 ATS 的异常(exception)。
这样，您就不需要完全禁止 ATS(正如您所指出的，这是一种不好的做法)，但您的应用仍将允许来自您的域的不安全调用。
为此，请打开您的 Info.plist 文件并添加 App Transport Security Settings。然后选择 Exception Domains 并将您的域添加到列表中。
这就是您的 Info.plist 在结尾处的样子:
