当我想用 JSONDecoder() 解码我的数据时，一些变量 returns nil
Some variables returns nil while I want to decode my data with JSONDecoder()
我正在使用 Urlsession 和 JSONDecoder 来获取和解码我的数据，但是在我解码它时，Weather 结构 returns nil 上的一些变量不知何故。它可能与utf8有关，但我不知道如何处理。
var request = URLRequest(url: URL(string: "myurlstring")
URLSession.shared.dataTask(with: request) {(data,resp,err) in
guard let data = data else { return }
do{
let decoder = JSONDecoder()
let weatherData = try decoder.decode(Weather.self, from: data)
completion(weatherData,nil)
} catch let err {
completion(nil,err)
}
}.resume()
我得到的是零值，你可以在这里看到：
但是在邮递员上我可以得到非零结果
这是我从邮递员那里得到的原始 json 数据

这是我第一次来这里。对不起我的错误。
问题是变量的名称，例如：
timezone_offset应该是完全一样的，不是timezoneOffset
您可以更新枚举 CodingKeys 以避免不良的命名习惯。
enum CodingKeys: String, CodingKey {
case lat, lon, timezone
case timezoneOffset = "timezone_offset"
case current, minutely, hourly, daily
}}
我正在使用 Urlsession 和 JSONDecoder 来获取和解码我的数据，但是在我解码它时，Weather 结构 returns nil 上的一些变量不知何故。它可能与utf8有关，但我不知道如何处理。
var request = URLRequest(url: URL(string: "myurlstring")
URLSession.shared.dataTask(with: request) {(data,resp,err) in
guard let data = data else { return }
do{
let decoder = JSONDecoder()
let weatherData = try decoder.decode(Weather.self, from: data)
completion(weatherData,nil)
} catch let err {
completion(nil,err)
}
}.resume()
我得到的是零值，你可以在这里看到：
但是在邮递员上我可以得到非零结果
这是我从邮递员那里得到的原始 json 数据

这是我第一次来这里。对不起我的错误。
问题是变量的名称，例如：
timezone_offset应该是完全一样的，不是timezoneOffset
您可以更新枚举 CodingKeys 以避免不良的命名习惯。
enum CodingKeys: String, CodingKey {
case lat, lon, timezone
case timezoneOffset = "timezone_offset"
case current, minutely, hourly, daily
}}
