swift - 在 Swift 中解码未封装在父 JSON 中的 JSON 列表

问题描述

所以以下是端点返回的内容。有没有更好的方法将其解码为对象数组，而不是将数据转换为字符串，附加字符串以使其成为有效的 JSON，然后将该字符串转换回数据并解码...

编辑：我提出的解决方案甚至不能很好地工作，因为对象之间没有逗号

edit2：正则表达式是我唯一的答案吗？

如果它只是封装在 {餐馆：[]} 中会容易得多:(

解决方案

这是 JSON 行格式。只需拆分\n并映射到 JSONDecoder。假设您将其作为一个长字符串：

let result = try json.split(separator: "\n")
    .map { Data($0.utf8) }
    .map { try JSONDecoder().decode(Record.self, from: $0) }
