arrays - 快速将字符串 json 转换为数组

Question

我有一个 JSON 文件并使用 Alamofire 解析它。如何将接收到的字符串 JSON 文件转换为数组，如下所示:

["name1", "name2", "name3", "name4"]

这是当前 Alamofire 打印时的输出:

name1
name2
name3
name4

这是 JSON 文件:

    [
        {
            name: "name1
        },
        {
            name: "name2",
            detail: "10"
        },
        {
            name: "name2",
            detail: "11"
        },
        {
            name: "name3",
            detail: "12"
        },
        {
            name: "name4",
            detail: "13"
        }
    ]

Alamofire :

AF.request(SEARCH_BASE_URL).response { (response) in
    do {
        self.se = try JSONDecoder().decode([Search].self, from: response.data!)
        for each in self.se {
            let list = Struct_Search(name: each.name, detail: each.detail)
            self.see.append(list)
            print(each.name)
        }
    } catch {
       print(error)
    }
}

map 是你的 friend

self.se = try JSONDecoder().decode([Search].self, from: response.data!)
let names = self.se.map(\.name)

为什么将Search映射到Struct_Search？这是多余的。
