Is it possible to do this in golang?
问题
我对golang中的.yaml文件有一个疑问，假设我有一个包含以下内容的.yaml文件：
print:
1
print:
2
print:
3
有没有办法获取yaml文件中的所有print？在golang中如何表示这种结构？例如，如果我在一个.yaml文件中有以下内容：
print:
1
在golang中，我可以这样表示它：
type Print struct {
Print int `yaml:"print"`
}
如果无法这样做，还有其他类似的方法吗？提前谢谢。
英文:
I have a doubt about the .yaml files in golang, suppose I have a .yaml file with the following content:
print:
1
print:
2
print:
3
Is there a way to get all the print in the yaml file? How would I represent that structure in golang? Because for example if I have this in a .yaml file:
print:
1
In golang I can represent it like this:
type Print struct {
Print int `yaml:"print"`
}
And if that cannot be done, what other way would there be to do something similar? Thanks in advance.

你的YAML不合法。在映射中，不能有相同的键出现多次。根据规范的3.2.1.1节：
映射节点的内容是一组无序的键/值节点对，限制条件是每个键都是唯一的。
相反，你可以使用映射到序列的方式。
print: [1,2,3]
并将其存储为[]int类型。
type Print struct {
Print []int `yaml:"print"`
}
英文:
Your YAML is not legal. You can't have the same key multiples times in a mapping. From 3.2.1.1 of the spec...
> The content of a mapping node is an unordered set of key/value node pairs, with the restriction that each of the keys is unique.
Instead, use a mapping to a sequence.
print: [1,2,3]
And store it as an []int.
type Print struct {
Print []int `yaml:"print"`
}
