我有 api 调用返回的结果,它就像对象数组(json 数组)复杂格式。我需要通过 golang 解析该结果,我该如何实现?以下数据是我从 api 调用中获得的结果。

最佳答案
您只漏掉了一点:您需要导出结构的字段:
type PublicKey struct {
Name string
Price string
}
它会起作用(在 Go Playground 上尝试):
[{Name:Galaxy Nexus Price:3460.00} {Name:Galaxy Nexus Price:3460.00}]
请注意,JSON 文本包含带有小写文本的字段名称,但 json
包“聪明”到足以匹配它们。如果它们完全不同,您可以使用结构标签告诉 json
包如何在 JSON 文本中找到它们(或者它们应该如何编码),例如:
type PublicKey struct {
Name string `json:"some_name"`
Price string `json:"JsonPrice"`
}
要解析其他 JSON 文本,请创建一个对 JSON 数据建模的 Go 结构。我建议格式化 JSON 以查看真实结构,例如你可以用这个online JSON formatter/validator .然后您可以解码为该结构的一部分。
或者简单地解码成一片 map ,例如[]map[string]interface{}
,但随后您需要对 map 进行索引以获取不同的值,并且您还需要使用类型断言来获取“类型化”值。
