如何在 swift 5 UIImageView 中使用在 mysql 中存储为 blob 的图像？

Question

这就是我的。

import Foundation

struct UserData: Decodable {
    let id: Int
    let first_name: String
    let last_name: String
    let gender: String
    let email: String
    let joined: String
    let profile_image: [String:[String]]?
    let rating: Float
    let rating_count: Int
    
}

我得到：

typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "profile_image", intValue: nil), _JSONKey(stringValue: "type", intValue: nil)], debugDescription: "Expected to decode Array<Any> but found a string/data instead.", underlyingError: nil))

如果我将结构更改为：

struct UserData: Decodable {
    let id: Int
    let first_name: String
    let last_name: String
    let gender: String
    let email: String
    let joined: String
    let profile_image: [String:String]?
    let rating: Float
    let rating_count: Int
    
}

我得到：

typeMismatch(Swift.String, Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "profile_image", intValue: nil), _JSONKey(stringValue: "data", intValue: nil)], debugDescription: "Expected to decode String but found an array instead.", underlyingError: nil))

不确定如何获取在数据库中存储为 blob 的图像并将其用作 UIImage。

这是它作为响应返回的方式：

 \"profile_image\" =     {\n        data =         (\n            47,\n            57,\n            106,\n            47,\n            52,\n            65,\n            65,\n            81,\n            83,\n            107,\n            90,\n            74,\n            82,\n            103,\n            65,\n            66,\n            65,\n            81,\n            69,\n            65,\n            83,\n            65,\n            66,\n            73,\n            65,\n            65,\n            68,\n            47,\n            50,\n            119,\n            66,\n            68,\n            65,\n            65,\n            89,\n            69,\n            66,\n            81,\n            89,\n            70,\n            66,\n            65,\n            89,\n            71,\n            66,\n            81,\n            89,\n            72,\n            66,\n            119,\n            89,\n            73,\n            67,\n            104,\n            65,\n            75,\n            67,\n            103,\n            107,\n            74,\n            67,\n
