我有 JSON ,带有键
{
"yearOfManufacture":"20/9/2018",
"carSize":8,
"isNew":true,
"carAssets":[
{
"color":"5761807993001",
"nativeId":"{\"app\":\"1234/Car/Native_App\",\"web\":\" /8888/Car/Native_Car_Desktop\"}"
}
]
}
我正在尝试使用 Codable 协议解析结构模型
struct Cars: Codable {
var yearOfManufacture: String?
var carSize: Int = 0
var isNew: Bool = true
var carAssets: [CarAssests]?
}
struct CarAssests: Codable {
var color: String?
var nativeId: String?
}
我收到错误,如数据无法读取,因为格式不正确。我尝试使用CodingKeys与解码器容器无法获得“nativeId的确切类型“:”{\“app \”:\“1234 / Car / Native_App \”,\“web \”:\“/ 8888 / Car / Native_Car_Desktop \”}“未获得此类型的确切数据类型。
let decoder = JSONDecoder()
decoder.dataDecodingStrategy = .deferredToData
if let jsonData = jsonString.data(using: .utf8) {
do {
print(jsonData)
let assets = try decoder.decode(Cars.self, from: jsonData)
print(assets)
} catch {
print(error.localizedDescription)
}
}
答案 0 :(得分:0)
我打赌你做的是这样的事情:
let jsonString = """
{
"yearOfManufacture": "20/9/2018",
"carSize": 8,
"isNew": true,
"carAssets": [
{
"color": "5761807993001",
"nativeId": "{\"app\":\"1234/Car/Native_App\",\"web\":\" /8888/Car/Native_Car_Desktop\"}"
}
]
}
"""
在多行字符串中,\"
和"
均表示字符"
。所以你必须写\\"
来获得两个字符\
和"
:
let jsonString = """
{
"yearOfManufacture": "20/9/2018",
"carSize": 8,
"isNew": true,
"carAssets": [
{
"color": "5761807993001",
"nativeId": "{\\"app\\":\\"1234/Car/Native_App\\",\\"web\\":\\" /8888/Car/Native_Car_Desktop\\"}"
}
]
}
"""
