Я делаю вызов API для получения некоторых данных, json dataAsString выглядит следующим образом ...
guard let dataAsString = String(data: data, encoding: .utf8)else {return}
print(dataAsString)
JSON DATA
{"patch_report":{"name":"macOS Updates","patch_software_title_id":"1","total_computers":"5","total_versions":"1","versions":{"version":{"software_version":"10.15.3","computers":{"size":"5","computer":{"id":"467","name":"EPART1BGF8J9"}}}}}}
do {
// make sure this JSON is in the format we expect
if let json = try JSONSerialization.jsonObject(with:data, options:[]) as? [String: Any] {
// try to read out a string array
if let patch_report = json["patch_report"] as? [String] {
print(patch_report)
}
}
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}
Как я могу использовать JSONSerialization для получения только определенных вложенных JSON значений? Многие говорили мне не использовать JSONSerialization, поэтому я предложил альтернативное решение. Ниже представлено решение Codable. Нажмите здесь для объяснения - Использование Codable с вложенным JSON!
Мне удалось найти ответы ниже ...
Получить вложенный JSON используя JSONSerialization
do {
// make sure this JSON is in the format we expect
if let json = try JSONSerialization.jsonObject(with:data, options:[]) as? [String: Any] {
// try to read out a string array
if let patch_report = json["patch_report"] as? [String:Any] {
if let versions = patch_report["versions"] as? [String:Any] {
if let version = versions["version"] as? [String:Any] {
if let software_version = version["software_version"] as? String {
print(software_version)
}
}}
} else {print("Not Available")}
}
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}
Получить вложенный Json используя Decoder
struct PatchReport: Codable {
var patch_report:Patch_report?
enum CodingKeys: String, CodingKey{
case patch_report = "patch_report"
}
struct Patch_report: Codable {
var name:String?
var patch_software_title_id:String?
var total_computers:String?
var total_versions:String?
var versions: Versions?
enum CodingKeys: String, CodingKey {
case name = "name"
case patch_software_title_id = "patch_software_title_id"
case total_computers = "total_computers"
case total_versions = "total_versions"
case versions = "versions"
}
struct Versions: Codable {
var version: Version?
enum CodingKeys: String, CodingKey {
case version = "version"
}
struct Version: Codable {
var software_version:String?
var computers:Computers?
enum CodingKeys: String, CodingKey {
case software_version = "software_version"
case computers = "computers"
}
struct Computers: Codable{
var size:String?
var computer:Computer?
enum CodingKeys: String, CodingKey {
case size = "size"
case computer = "computer"
}
struct Computer: Codable{
var id:String?
var name:String?
enum CodingKeys: String, CodingKey {
case id = "id"
case name = "name"
}
}
}
}
}
}
}
let response = try! JSONDecoder().decode(PatchReport.self, from: data)
print(String(response.patch_report?.total_computers ?? ""))
