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，所以我试图通过源代码和单元测试找到必要的信息。

我正在使用HTTPie来执行来自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 console来验证aggregate.id是否正确。 command.id只是一个随机uuid()。

将Malformed command作为回复我做错了什么？

Answer 1

免责声明：我是wolkenkit的开发人员之一。

在内部，命令是使用commands-events模块构建的，该模块也用于验证传入的命令。

实际错误来自tailwind，wolkenkit使用它作为使用命令和事件的应用程序的基础。在内部，此commands-events代码calls the isWellformed function，而checks the schema依次为{{3}}。

从我看到的一切似乎都很好，除了metadata.timestamp应该是number，而不是string。我想如果你改变这个，那么wolkenkit会愉快地接受你的命令。

用于发送命令的Wolkenkit REST API返回“格式错误的命令”
