swift中的数组JSON解码

let jsonString = "[{\"name\":\"John\",\"age\":30},{\"name\":\"Jane\",\"age\":25}]"
guard let jsonData = jsonString.data(using: .utf8) else {
    // 错误处理
    return
}

guard let jsonArray = try JSONSerialization.jsonObject(with: jsonData, options: []) as? [[String: Any]] else {
    // 错误处理
    return
}

var persons: [Person] = []
for jsonItem in jsonArray {
    if let name = jsonItem["name"] as? String, let age = jsonItem["age"] as? Int {
        let person = Person(name: name, age: age)
        persons.append(person)
    }
}

struct Person: Codable {
    let name: String
    let age: Int
}

let decoder = JSONDecoder()
do {
    let persons = try decoder.decode([Person].self, from: jsonData)
    // 处理解析后的数组
} catch {
    // 错误处理
}
