我需要帮助在ios Swift中阅读json。我知道我可以使用decodable，但这是我的JSON的一个示例。当我尝试xith decodable时，我总是得到一个零变量。
谢谢你的帮助
[
{
"name": "Bob",
"age": "16",
"employed": "No"
},
{
"name": "Vinny",
"age": "56",
"employed": "Yes"
}
]
这是我的密码，用可解码的
struct personResult: Decodable{
var person: [Person]
}
struct Person:Decodable{
var name: String
var age: String
var employed: String
}
这就是我的职责
func getJson() {
let url = URL(string: myUrl)!
let task = URLSession.shared.dataTask(with: url, completionHandler: { (data, response, error) in
if let error = error {
print("Error : \(error)")
return
}
guard let httpResponse = response as? HTTPURLResponse,
(200...299).contains(httpResponse.statusCode) else {
print("Error with the response, unexpected status code: \(response)")
return
}
if let data = data {
print(data)
do {
let result = try JSONDecoder().decode(personResult.self, from: data)
print(result)
}catch _ {
print("errror during json decoder")
}
}
})
task.resume()
}
}
我总是在我的catch中输入，并打印错误消息
您的JSON是一个数组而不是字典，只是您的Person结构
struct Person:Decodable{
var name: String
var age: String
var employed: String
}
则在函数中：
func getJson() {
let url = URL(string: myUrl)!
let task = URLSession.shared.dataTask(with: url, completionHandler: { (data, response, error) in
if let error = error {
print("Error : \(error)")
return
}
guard let httpResponse = response as? HTTPURLResponse,
(200...299).contains(httpResponse.statusCode) else {
print("Error with the response, unexpected status code: \(response)")
return
}
if let data = data {
print(data)
do {
let result = try JSONDecoder().decode([Person].self, from: data)
print(result)
}catch let error {
print(error)
}
}
})
task.resume()
}
}
