用于发送命令的 Wolkenkit REST API 返回"Malformed command"

Question

我正在尝试使用Wolkenkit的REST API发送命令。我没有在文档中找到任何信息，因此我尝试通过浏览源代码和单元测试来找到必要的信息。

我正在使用httpie来执行CLI的请求：

> http --verbose post https://local.wolkenkit.io:3500/v1/command id=12bf5b37-e0b8-42e0-8dcf-dc8c4aefc000 context:='{"name": "mycontext"}' aggregate:='{"name": "label", "id": "26c01e1f-abb8-42fa-82cf-60ca4a6bfbfa"}' name=create data:='{"label": "third"}' custom:='{}' metadata:='{"timestamp": "1504167240279", "correlationId": "12bf5b37-e0b8-42e0-8dcf-dc8c4aefc000", "causationId": "12bf5b37-e0b8-42e0-8dcf-dc8c4aefc000"}'

Malformed command.

我使用Wolkenkit控制台验证aggregate.id是否正确。command.id只是随机uuid()。

让Malformed command作为响应我错了什么？

免责声明：我是Wolkenkit的开发人员之一。

在内部，这些命令是使用命令 - 事件模块构建的，该模块也用于验证传入命令。

实际错误来自沃尔肯基特（Wolkenkit）在引擎盖下用作使用命令和事件的应用程序的基础的尾风。在内部，此代码调用commands-events的isWellformed函数，该功能依次检查命令的模式。

从我看到的一切似乎都很好，除了metadata.timestamp应该是number，而不是string。我认为，如果您更改此操作，那么Wolkenkit将快乐地接受您的命令。
