let title, previewText: String
var timestampValue: String
enum CodingKeys: String, CodingKey {
case timeshamp, title
case postID = "postId"
case previewText = "preview_text"
case likesCount = "likes_count"

类型"Post"不符合协议"可解码">

Answer 1

CodingKeys中的变量名称与Post结构中的不同。

例如，使用：

case likesCount = "likesCount"
