快速解析双JSON编码数组并访问它
快速解析双JSON编码数组并访问它
提问于 2015-05-15 15:57:56
我需要解析来自JSON的数组中的10个数组，然后才能对其进行快速访问。我可以通过REST获取数据并在控制台上打印出来，但我不知道如何将其实际保存到处理中。
JSON阵列结构：
[[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge],
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge]]这些数组基本上返回整数和字符串。
如何将它们保存在相同的样式(数组中的数组)并访问它们？
下面是我到现在为止的代码：
@IBAction func buttonLoad(sender: AnyObject) {
// Setting up the URL
let myUrl = NSURL(string: "http://hugelol.com/api/front.php");
// Request
let request = NSMutableURLRequest(URL:myUrl!);
request.HTTPMethod = "POST";
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil
{
println("error=\(error)")
return
}
// Prints server response
println("response = \(response)")
// Prints the double array
let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
println("responseString = \(responseString)")
}
task.resume()
}我尝试过许多不同的方法，但很难理解如何做到这一点。我也尝试过swiftyJSON，但我仍然不知道如何将数据保存到一个快速数组中。我差点把头撞到墙上。感谢您的阅读。

这部分代码应该为您提供预期的结果。
....
// Setting up the URL
let myUrl = NSURL(string: "http://hugelol.com/api/front.php");
// Request
let request = NSMutableURLRequest(URL:myUrl!);
request.HTTPMethod = "POST";
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil
{
println("error=\(error)")
return
}
if let jsonString = JSON(data: data).rawString() as String? {
if let dataFromString = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
let json = JSON(data: dataFromString)
// uncomment necessary access method
// for (index: String, subJson: JSON) in json {
// println("Arr = \(subJson)")
// }
// OR
// println(json[0][0])
}
}
}
task.resume() ……

尝试使用NSJSONSerialization。它将解析JSON并返回一个NSObject树。
if let result: AnyObject = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions(0), error: nil) {...}页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
