我正在使用Swift和JSONPlaceholder。我想检索https://jsonplaceholder.typicode.com/photos
中包含的所有数据。我创建了一个添加到url的函数,下载了JSON,但是后来我不知道如何获取标题和thumbnailUrl来传递,然后填充tableView。过去我使用了这段代码,但是现在无法使用,因为在JSONPlaceholder上没有数组。
是否有任何帮助重新排列代码以读取和获取jsonplaceholder元素的帮助?
func loadList(){
let url = URL(string: urlReceived)
var myNews = NewInfo()
let task = URLSession.shared.dataTask(with: url!) {
(data, response, error) in
if error != nil{
print("ERROR")
}
else{
do {
if let content = data{
let myJson = try JSONSerialization.jsonObject(with: content, options: .mutableContainers)
//print(myJson)
if let jsonData = myJson as? [String : Any] {
if let myResults = jsonData["list"] as? [[String : Any]]{
//dump(myResults)
for value in myResults{
//Read time string from root
if let time = value ["dt_txt"] as? String{
myNews.time = time
}
//Read main container
if let main = value["main"]
as? [String : Any]{
if let temperature = main["temp"] as? Double {
myNews.temperature = String(temperature)
}
}
//Read from weather container
if let weather = value["weather"] as? [[String: Any]]{
for value in weather{
if let weatherContent = value["description"] as? String{
myNews.weatherDescription = weatherContent
}
}
}
self.myTableViewDataSource.append(myNews)
}
dump(self.myTableViewDataSource)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
}
}
catch{
}
}
}
task.resume()
}//End func

Okey,因此使用Alamofire + SwiftyJSON,您可以执行以下操作:
func loadList(){
let url = "https://jsonplaceholder.typicode.com/photos"
AF.request(url).responseJSON { (response) in
switch response.result {
case .success(let value):
let json = JSON(value)
print(json)
for value in json.arrayValue {
let url = value.dictionaryValue["url"]!.stringValue
let albumId = value.dictionaryValue["albumId"]!.stringValue
let thumbnailUrl = value.dictionaryValue["thumbnailUrl"]!.stringValue
let id = value.dictionaryValue["id"]!.stringValue
let title = value.dictionaryValue["title"]!.stringValue
// Add this album to array.
let album = AlbumModel(id: id, albumId: albumId, title: title, thumbnailUrl: thumbnailUrl)
albums.append(album)
}
case .failure(let error):
print(error)
}
}
}
编辑:
我为价值建立了模型
class AlbumModel {
var id: String?
var albumId: String?
var title: String?
var thumbnailUrl: String?
init(id: String?, albumId: String?, title: String?, thumbnailUrl: String?){
self.id = id
self.albumId = albumId
self.title = title
self.thumbnailUrl = thumbnailUrl
}
}
此后,只需创建一个var albums = [AlbumModel]()
之类的数组,即可将所有相册添加到此数组中。在tableViewcell中易于使用(示例:albums[indexPath.row].id
)
