将 JSON 转换为 yaml 时出现“无法解析 YAML 错误”

Question

我使用JSON converter to YML 格式。它工作正常。

但是Validate YAML检查的YAML结果无效

错误之一：

Error: Unable to parse.
Line: 36    - Ref: ALIYUN::StackId

请帮我从 JSON 转换为有效的 YML。谢谢。

Answer 1

你不应该使用那个验证器，它声称是最好的，但它实际上并没有确认 YAML 1.2 和 YAML 1.1。

它抱怨的 YAML 行 (36) 是：

         - Ref: ALIYUN::StackId

并且损坏的验证器无法处理的事情之一是不带引号的标量字符串中的冒号（即ALIYUN::StackId）。由于冒号后面没有空格或（在 YAML 1.2 中）前后有双引号，因此 从不 表示键值对，因此不会与此有效的 YAML 混淆。

只需尝试在 PyYAML 中加载转换的输出，或将其粘贴到this 站点（基于 PyYAML），您会发现没有问题。虽然 PyYAML 也不完美（并且仅支持 YAML 1.1 的大部分内容），但它比您一直使用的网站要好得多。

我使用json2yaml package将JSON转换为YML，效果很好。
