(Rails 5) 为什么此集成测试关键字参数参数会导致弃用警告？

Question

我已经尝试调整我的 post 控制器的集成测试以符合 Rails 5 关键字参数结构，但我仍然收到弃用警告。我已经观看了几个视频并通读了文档，但我仍然无法发现它。知道我的语法哪里错了吗？

作为一个还在摸索中的程序员，在此先感谢您的帮助！如果您希望我分享任何其他代码片段，请告诉我！

您的弃用警告似乎必须执行 Rails 5.0.0.1 检测关键字参数的方式。为什么会这样，我也不知道。

为了满足这个 depraction 警告，您需要将参数括在花括号中。这样就被识别为一个Hash，满足Rails。

 post sessions_path, { params: { email: "user1@example.com", password: "password" } }
