Ios Swift解码JSON-无法解码
我无法解码我的JSON文件。如果我只解码一个字符串,它就可以工作,但是现在用我的struct它就不工作了。我做错什么了吗 我要解码的结构:Ios Swift解码JSON-无法解码,ios,json,swift,decode,Ios,Json,Swift,Decode,我无法解码我的JSON文件。如果我只解码一个字符串,它就可以工作,但是现在用我的struct它就不工作了。我做错什么了吗 我要解码的结构: struct Comment: Decodable, Identifiable { var id = UUID() var title : String var comments : [String] private enum Keys: String, CodingKey { case response =
struct Comment: Decodable, Identifiable {
var id = UUID()
var title : String
var comments : [String]
private enum Keys: String, CodingKey {
case response = "Response"
case commentsArray = "commentsArray"
case title = "title"
case comments = "comments"
}
init(from decoder: Decoder) throws {
let values = try decoder.container(keyedBy: Keys.self)
let response = try values.nestedContainer(keyedBy: Keys.self, forKey: .response)
let commentsArray = try response.nestedContainer(keyedBy: Keys.self, forKey: .commentsArray)
title = try commentsArray.decodeIfPresent(String.self, forKey: .title)!
comments = try commentsArray.decodeIfPresent([String].self, forKey: .comments)!
}
}
我的JSON:
{"Response": {
"commentsArray":[
{
"title": "someTitle",
"comments": [
"optionOne",
"optionTwo"
]
},
{
"title": "title",
"comments": [
"optionOne",
"optionTwo"
]
},
{
"title": "someto",
"comments": [
"optionOne",
"optionTwo"
]
}
]
}
}
使用这些结构来解码json
struct Response: Codable {
var response : Comments
private enum Keys: String, CodingKey {
case response = "Response"
}
}
struct Comments: Codable {
var commentsArray : [comment]
}
struct comment: Codable {
let title: String
let comments: [String]
}
使用这些结构来解码json
struct Response: Codable {
var response : Comments
private enum Keys: String, CodingKey {
case response = "Response"
}
}
struct Comments: Codable {
var commentsArray : [comment]
}
struct comment: Codable {
let title: String
let comments: [String]
}
我认为您不希望以这种方式构造代码。您有一个层次结构,您正试图在一个更平坦的结构中捕获它
Response
CommentsList
Comments
Title
Comment
Comment
...
Comments
...
因此,您可能希望执行以下操作:
struct响应:可解码{
var commentsArray:[注释]
init(来自解码器:解码器){
let container=try!decoder.container(keyedBy:ResponseCodingKeys.self)
let response=try!container.nestedContainer(keyedBy:ListCodingKeys.self,forKey:.response)
commentsArray=try!response.decode([Comments].self,forKey:.commentsArray)
}
枚举响应编码键:字符串,编码键{case response=“response”}
枚举列表编码键:字符串,编码键{case commentsArray}
}
结构注释:可解码{
var id=UUID()
变量标题:字符串
var注释:[字符串]
}
