Swift 4 JSON可编码ID作为键 [英] Swift 4 JSON Codable ids as keys
本文介绍了Swift 4 JSON可编码ID作为键的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想将Swift 4的可编码功能与json一起使用,但其中一些键没有设置名称.而是有一个数组,它们是ID,例如
I would like to use Swift 4's codable feature with json but some of the keys do not have a set name. Rather there is an array and they are ids like
{
"status": "ok",
"messages": {
"generalMessages": [],
"recordMessages": []
},
"foundRows": 2515989,
"data": {
"181": {
"animalID": "181",
"animalName": "Sophie",
"animalBreed": "Domestic Short Hair / Domestic Short Hair / Mixed (short coat)",
"animalGeneralAge": "Adult",
"animalSex": "Female",
"animalPrimaryBreed": "Domestic Short Hair",
"animalUpdatedDate": "6/26/2015 2:00 PM",
"animalOrgID": "12",
"animalLocationDistance": ""
,其中您看到181个ID.有人知道如何处理181,以便可以将其指定为密钥吗?该数字可以是任何数字,并且每个数字都不相同.
where you see the 181 ids. Does anyone know how to handle the 181 so I can specify it as a key? The number can be any number and is different for each one.
想要这样的东西
struct messages: Codable {
var generalMessages: [String]
var recordMessages: [String]
}
struct data: Codable {
var
}
struct Cat: Codable {
var Status: String
var messages: messages
var foundRows: Int
//var 181: [data] //What do I place here
}
谢谢.
推荐答案
请检查:
struct ResponseData: Codable {
struct Inner : Codable {
var animalID : String
var animalName : String
private enum CodingKeys : String, CodingKey {
case animalID = "animalID"
case animalName = "animalName"
}
}
var Status: String
var foundRows: Int
var data : [String: Inner]
private enum CodingKeys: String, CodingKey {
case Status = "status"
case foundRows = "foundRows"
case data = "data"
}
}
let json = """
{
"status": "ok",
"messages": {
"generalMessages": ["dsfsdf"],
"recordMessages": ["sdfsdf"]
},
"foundRows": 2515989,
"data": {
"181": {
"animalID": "181",
"animalName": "Sophie"
},
"182": {
"animalID": "182",
"animalName": "Sophie"
}
}
}
"""
let data = json.data(using: .utf8)!
let decoder = JSONDecoder()
do {
let jsonData = try decoder.decode(ResponseData.self, from: data)
for (key, value) in jsonData.data {
print(key)
print(value.animalID)
print(value.animalName)
}
}
catch {
print("error:\(error)")
}
