Swift-解析数据错误-Swift.DecodingError.dataCorrupted [英] Swift - Parsing Data Error - Swift.DecodingError.dataCorrupted
问题描述
我将SwiftSoup与Codable结合使用以获取正确的元素并解析数据.但是，我收到此错误:
I'm using SwiftSoup in combination with Codable to get the correct element(s) and parse the data. However, I receive this error:
JSON decode failed: Swift.DecodingError.dataCorrupted(Swift.DecodingError.Context(codingPath: [], debugDescription: "The given data was not valid JSON.", underlyingError: Optional(Error Domain=NSCocoaErrorDomain Code=3840 "No value." UserInfo={NSDebugDescription=No value.})))
我已经在线查看了，确保我的数据正确匹配，甚至将预期的类型从Int更改为String，但出现错误，指出了预期的Int.
I've looked online, ensure my data matches correctly, even change the expected types from Int to String but got an error stating an Int was expected.
这是我正在接收的数据，可以在控制台中打印:
This is the data I am receiving and can print in the console:
data -
{"test":0,"ppace":85,"pshooting":92,"ppassing":91,"pdribbling":95,"pdefending":38,"pphysical":65,"acceleration":91,"sprintspeed":80,"agility":91,"balance":95,"reactions":94,"ballcontrol":96,"dribbling":96,"positioning":93,"finishing":95,"shotpower":86,"longshotsaccuracy":94,"volleys":88,"penalties":75,"interceptions":40,"headingaccuracy":70,"marking":32,"standingtackle":35,"slidingtackle":24,"vision":95,"crossing":85,"freekickaccuracy":94,"shortpassing":91,"longpassing":91,"curve":93,"jumping":68,"stamina":72,"strength":69,"aggression":44,"composure":96}
这是我的功能:
func parseData() {
do {
let html = try String(contentsOf: url!, encoding: String.Encoding.ascii)
let doc: Document = try! SwiftSoup.parse(html)
let elements = try doc.getAllElements()
for element in elements {
switch element.id() {
case "player_stats_json":
let content = try! element.getElementsContainingText("ppace").text()
print(content.utf8)
let jsonData = content.data(using: .utf8)
do {
self.player = try JSONDecoder().decode(PlayerModel.self, from: Data(jsonData!))
} catch let jsonError as NSError {
print("JSON decode failed: \(jsonError)")
print("data - \(content)")
}
default:
break
}
}
} catch Exception.Error(type: let type, Message: let message) {
print(type)
print(message)
} catch {
print("")
}
}
这是我的模型文件:
struct PlayerModel: Codable {
var test: Int
var ppace: Int
var pshooting: Int
var ppassing: Int
var pdribbling: Int
var pdefending: Int
var pphysical: Int
var acceleration: Int
var sprintspeed: Int
var agility: Int
var balance: Int
var reactions: Int
var ballcontrol: Int
var dribbling: Int
var positioning: Int
var finishing: Int
var shotpower: Int
var longshotsaccuracy: Int
var volleys: Int
var penalties: Int
var interceptions: Int
var headingaccuracy: Int
var marking: Int
var standingtackle: Int
var slidingtackle: Int
var vision: Int
var crossing: Int
var freekickaccuracy: Int
var shortpassing: Int
var longpassing: Int
var curve: Int
var jumping: Int
var stamina: Int
var strength: Int
var aggression: Int
var composure: Int
}
我已经将变量名与每个键匹配了两倍和三倍.我已经将输出的数据粘贴到了在线JSON验证器中的控制台中，并且没有出现错误.我现在是genuinley，因为我不知道自己哪里出了问题，现在才挠头.
I've double and tripled checked the variable names match up with each key. I've pasted the outputted data in the console in an Online JSON validator, and no errors appear. I'm genuinley left scratching my head right now, because I can't understand where I've gone wrong.
推荐答案
我仍然不知道您的解析有什么问题.我已经设法解析了您的html，但我不知道为什么当尝试使用Int而不是Uint8时，它总是无法返回正确的值.这对我有用:
I still have no idea whats wrong with your parsing. I've managed to parse your html but I have no idea why when trying to use Int instead of Uint8 it kept failing to return the right values. This is what worked for me:
import UIKit
import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true
struct PlayerModel: Codable {
let test: UInt8
let ppace: UInt8
let pshooting: UInt8
let ppassing: UInt8
let pdribbling: UInt8
let pdefending: UInt8
let pphysical: UInt8
let acceleration: UInt8
let sprintspeed: UInt8
let agility: UInt8
let balance: UInt8
let reactions: UInt8
let ballcontrol: UInt8
let dribbling: UInt8
let positioning: UInt8
let finishing: UInt8
let shotpower: UInt8
let longshotsaccuracy: UInt8
let volleys: UInt8
let penalties: UInt8
let interceptions: UInt8
let headingaccuracy: UInt8
let marking: UInt8
let standingtackle: UInt8
let slidingtackle: UInt8
let vision: UInt8
let crossing: UInt8
let freekickaccuracy: UInt8
let shortpassing: UInt8
let longpassing: UInt8
let curve: UInt8
let jumping: UInt8
let stamina: UInt8
let strength: UInt8
let aggression: UInt8
let composure: UInt8
}
let url = URL(string:"https://www.futbin.com/21/player/541/lionel-messi")!
URLSession.shared.dataTask(with: url) { data, response, error in
guard let data = data, let html = String(data: data, encoding: .utf8) else { return }
if let start = html.range(of: #"<div style="display: none;" id="player_stats_json">"#)?.upperBound,
let end = html[start...].range(of: #"</div>"#)?.lowerBound {
let json = html[start..<end]
do {
let player = try JSONDecoder().decode(PlayerModel.self, from: Data(json.utf8))
print(player)
} catch {
print(error)
}
}
}.resume()
这将打印
This will print
PlayerModel(test:0，ppace:85，pshooting:92，ppassing:91， 运球:95，防守:38，身体:65，加速度:91， sprintspeed:80，敏捷性:91，平衡:95，反应:94，控球: 96，运球:96，定位:93，射门:95，射门力量:86， 远射命中率:94，排球:88，罚球:75，拦截:40， 航向精度:70，标记:32，站立式:35，滑动式: 24，视野:95，横传:85，任意球准确性:94，短传:91， 长传:91，弯道:93，跳跃:68，耐力:72，力量:69， 侵略性:44，沉着感:96)
