我正在嘗試決議具有以下格式的 JSON 檔案：
{
"OnDemand" : {
"program" : [
{
"Sunday" : "https://example1.m4a",
"SundaySharePage" : "https://example1",
"name" : "Example 1",
"weekdays" : "Sunday"
},
{
"Monday" : "https://example2.m4a",
"MondaySharePage" : "https://example2",
"name" : "Example 2",
"weekdays" : "Monday"
}
]
}
使用此代碼：
struct AllPrograms: Codable {
let OnDemand: [Dictionary<String,String>: Programs]
}
struct Programs: Codable {
let program:Array<String>
}
func parsePrograms (urlString:String) {
if let url = URL(string: urlString) {
URLSession.shared.dataTask(with: url) { data, response, error in
if let data = data {
let jsonDecoder = JSONDecoder()
do {
let parsedJSON = try jsonDecoder.decode(AllPrograms.self, from: data)
print(parsedJSON.OnDemand)
} catch {
print(error)
}
}
}.resume()
}
}
但我收到了這個錯誤：
typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "OnDemand", intValue: nil)], debugDescription: "Expected to decode Array<Any> but found a dictionary instead.", underlyingError: nil))
我該如何解決？謝謝！
uj5u.com熱心網友回復：
使用此代碼塊創建您的模型，
import Foundation
// MARK: - AllPrograms
struct AllPrograms: Codable {
let onDemand: OnDemand
enum CodingKeys: String, CodingKey {
case onDemand = "OnDemand"
}
}
// MARK: - OnDemand
struct OnDemand: Codable {
let program: [Program]
}
// MARK: - Program
struct Program: Codable {
let sunday, sundaySharePage: String?
let name, weekdays: String
let monday, mondaySharePage: String?
enum CodingKeys: String, CodingKey {
case sunday = "Sunday"
case sundaySharePage = "SundaySharePage"
case name, weekdays
case monday = "Monday"
case mondaySharePage = "MondaySharePage"
}
}
您可以使用此網站根據 json 資料輕松創建模型。
順便說一句，在您的 json 中}缺少一個。如果您使用硬編碼，請檢查您的 json。
