我想从 http 资源中解析一个 json（这是我的路由器，所以 http 是强制性的）。
在我设置Info.plist App Security Transport我确实获得连接后，我通过第一次尝试获取数据：
let sphDataAddress = "http://speedport.ip/data/status.json"
let url = URL(string: sphDataAddress)!
let jsonData = try! Data(contentsOf: url) // ! is just for testing reason and will be in real app by guard let
print("data \(jsonData)") // shows that the received Data are 5077bytes
struct User {
let vartype: String
let varid: String
let varvalue: Company
init?(dict: [String: Any]) {
guard
let vartype = dict["vartype-data"] as? String,
let varid = dict["valid-data"] as? String,
let varvalueDict = dict["company"] as? [String: Any],
let varvalue = Company(dict: varvalueDict)
else {
return nil
}
self.vartype = vartype
self.varid = varid
self.varvalue = varvalue
}
struct Company {
let vartype: String
let varid: String
let varvalue: String
init?(dict: [String: Any]) {
guard
let vartype = dict["vartype-sub"] as? String,
let varid = dict["varid-sub"] as? String,
let varvalue = dict["varvalue-Sub"] as? String else {
return nil
}
self.vartype = vartype
self.varid = varid
self.varvalue = varvalue
}
}
}
if let json = try? JSONSerialization.jsonObject(with: jsonData, options: []) {
if let jsonArray = json as? [[String: Any]] {
let users = jsonArray.flatMap { $0.map { $0} }
let zun = users.count
print(users, zun)
}
}
第二次尝试：我也尝试过，但没有成功：//我将它放入查看负载只是为了测试它！
struct RouterData: Decodable {
let vartype: String?
let varid: String?
let varvalue: String?
}
override func viewDidLoad() {
super.viewDidLoad()
let jsonUrlString = "http://speedport.ip/data/status.json"
guard let url = URL(string: jsonUrlString) else { return }
URLSession.shared.dataTask(with: url) { (data, response, err) in
//perhaps check err checked by print(response)
//also perhaps check response status 200 OK
guard let data = data else { return }
do {
let courses = try JSONDecoder().decode([RouterData].self, from: data)
print(courses)
} catch let jsonErr {
print("Error serializing json:", jsonErr)
}
}.resume()
}
控制台中的错误：
typeMismatch(Swift.String, Swift.DecodingError.Context(codingPath: [Foundation.(_JSONKey in _12768CA107A31EF2DCE034FD75B541C9)(stringValue: "Index 25", intValue: Optional(25)), JsonParseSwift4.RouterData.(CodingKeys in _DD16AFvarBB8A755D282DC27E60A666)。 ，debugDescription：“预期解码字符串，但找到了一个数组。”，基础错误：无））
这就是来自源（路由器）的（完整）json结构

来自路由器的数据是：
JSON 只是一个片段，我想展示的是它varvalue曾经是一个字符串，一次是[]带有子数据但相同var的。
