How to use json tags in anonymously nested struct?

问题

我有以下匿名结构体:

func wrapHal(selfHref string) interface{} {
	return struct {
		Links struct `json:"_links"`{
			Self struct {
				Href string
			}
		}
	}{
		Links: struct {
			Self struct {
				Href string
			}
		}{
			Self: struct {
				Href string
			}{
				Href: selfHref,
			},
		},
	}
}

我想知道在使用json.Marshal将其序列化为JSON时,是否可以将Links重命名为_links

是否可能?如果是,如何实现?

英文:

I have the following anonymous struct

func wrapHal(selfHref string) interface{} {
	return struct {
		Links struct `json: "_links"`{ # does not work, returns error "expected expression"
			Self struct {
				Href string
			}
		}
	}{
		Links: struct {
			Self struct {
				Href string
			}
		}{
			Self: struct {
				Href string
			}{
				Href: selfHref,
			},
		},
	}
}

I want to know if it is possible to rename from Links to _links when I serialize to JSON using json.Marshal

Is it possible? If so, how?

问题出在基本结构上。

	type s struct {
		Links struct {
			Self struct {
				Href string
			}
		} `json:"_links"`
	}

这是正确的语法。

英文:

The issue is with the base structure.

	type s struct {
		Links struct {
			Self struct {
				Href string
			}
		} `json:"_links"`
	}

is the correct syntax
