Question

我不明白，为什么我在Scala Play REPL中收到此错误，但Play项目似乎一切正常。这是在我运行play console：

之后

scala> import play.api.libs.Crypto
import play.api.libs.Crypto

scala> Crypto.encryptAES("password")

我想用它来加密控制台中的字符串。这个错误究竟意味着什么？

Play Framework 2.2.1 / Scala 2.10.3 / Java 8 64bit

Answer 1

您需要一个正在运行的Play应用程序来使用该方法加密任何内容，因为它需要使用应用程序机密来加密数据。

两种解决方案：

使用encryptKey的其他版本，并传递您的应用程序密码，例如：
```
Crypto.encryptAES("password", "yourapplicationsecret".substring(0, 16))
```
不是运行play console，而是运行play test:console，然后执行以下代码以确保正在运行的应用程序：
```
import play.api.test._
Helpers.running(FakeApplication()) { Crypto.encryptAES("password") }
```

Scala / Play / REPL：配置错误（play.api.libs.Crypto）
