json - 在Swift中解析json blob字段

我正在从Web Service快速读取JSON，其格式如下

[{
   "id":1,
   "shopName":"test",
   "shopBranch":"main",
   "shopAddress":"usa",
   "shopNumber":"5555555",
   "logo":[-1,-40,-1,-32],
   "shopPath":"test"
},
{
   "id":2,
   "shopName":"test",
   "shopBranch":"main",
   "shopAddress":"usa",
   "shopNumber":"66666666",
   "logo":[-1,-50,-2,-2],
   "shopPath":"test"
}]

我已经设法轻松地读取了所有字符串，但是当涉及徽标部分时，我不确定该怎么办，这是mySQL数据库中的blob字段，表示要在swift UI中检索的图像，这是我执行此操作的代码，但我不断出错，无法找到正确的方法：

struct Brand: Decodable {
    private enum CodingKeys: String, CodingKey {
        case id = "id"
        case name = "shopName"
        case branch = "shopBranch"
        case address = "shopAddress"
        case phone = "shopNumber"
        case logo = "logo"
        case path = "shopPath"
    }
    let id: Int
    let name: String
    let branch: String
    let address: String
    let phone: String
    let logo: [String]
    let path: String
}
func getBrandsJson() {
    let url = URL(string: "http://10.211.55.4:8080/exam/Test")
    URLSession.shared.dataTask(with: url!, completionHandler: {(data, response, error) in
        guard let data = data, error == nil else {
            print(error!);
            return
        }
        print(response.debugDescription)
        let decoder = JSONDecoder()
        let classes = try! decoder.decode([Brand].self, from: data)
        for myClasses in classes {
            print(myClasses.branch)
            if let imageData:Data = myClasses.logo.data(using:String.Encoding.utf8){
                let image = UIImage(data:imageData,scale:1.0)
                var imageView  : UIImageView!
            }
        }
    }).resume()
}

有人可以解释如何正确地搜索我，但是没有运气的方法

最佳答案

更换

let logo: [String]

与

let logo: [Int]

得到错误使用

do {
     let classes = try JSONDecoder().decode([Brand].self, from: data)
}
catch {
  print(error)
}
