Mulesoft 安全属性配置密钥未读取变量

Question

我正在尝试构建一个使用安全属性配置的 Mulesoft 应用程序。我创建了一个 settings.unencrypted.yaml 文件，如下所示：

sftp_username: "unencryptedUsername"
sftp_password: "unencryptedPassword"
sftpUrl: "unencryptedUrl"

然后我运行了以下命令 java -cp .\secure-properties-tool.jar com.mulesoft.tools.SecurePropertiesTool file encrypt AES CBC secretKey .\settings.unencrypted.yaml .\settings.yaml，它生成了带有加密字符串的 yaml 文件。然后在 Mulesoft 内部，我添加了一个安全属性配置，如下所示：

接下来，我将${encryptionKey} 添加到运行配置中，如下所示：

现在我将 SFTP“在新文件或更新文件上”项添加到流中。在那里，我尝试如下配置 SFTP 服务器：

当我点击“测试连接我得到以下错误：

当我在安全属性配置中对密钥进行硬编码时，一切正常。为什么我不能访问传入的变量作为我的密钥？

Answer 1

之前我们都认为 .properties 文件的键值在测试连接期间作为属性参数传递时不支持。加密的安全属性配置也是如此。

我最近观察到，您不必通过运行时部署应用程序即可使测试连接正常工作。您无需实际部署应用即可测试连接并获取元数据。

要完成此操作，请尝试将 global-property 中的属性键和值添加到您的 global elements 中。

在您的 XML global elements 部分中搜索 global-property。

在您的情况下，您需要添加 encryptionKey 作为密钥名称，yourKey 作为全局属性的加密密钥。任何其他键值属性都应遵循相同的原则。

此外，您不必总是在全局属性中传递encryptionkey。只需编辑 Studio exe 文件夹中的 anypointstudio.ini 文件并添加 -DencryptionKey=yourKey。您也可以在运行配置的环境属性选项卡中传递它。但不能总是保证最后一种方法。

Cheers ! It's gonna work fine.

注意

大多数 mule studio 版本，比如 Mule 3.x.x 或 4.x.x，都不太支持 Test Connections、Auto Run、Data Sense 等功能。

Answer 2

很遗憾，无法通过测试连接使用运行配置。

Test Connection 仅适用于纯文本，因为它是一个简单的设计时工具。

如果您正常运行应用程序，它应该可以按设计运行。

我知道的唯一解决方法是使用所需属性的环境变量启动 Studio。但即便如此，当使用“测试连接”时，应用程序本身并未启动，因此无法访问安全属性等上下文。
