嘿,我是swift的新手,我需要解析这个JSON并获取从webservice返回的“name”的值:
{name = "Sameer Hussain";}
到目前为止,这是我的代码:
var url: NSURL = NSURL(string: "http://xxxxxxxxx.com/xxxxx/xxxx.php")!
var request:NSMutableURLRequest = NSMutableURLRequest(URL:url)
var bodyData = "data=something"
request.HTTPMethod = "POST"
//request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
{
(response, data, error) in
// println(data)
var strData = NSString(data: data, encoding: NSUTF8StringEncoding)
//println(strData)
var err1: NSError?
var json2 = NSJSONSerialization.JSONObjectWithData(strData!.dataUsingEncoding(NSUTF8StringEncoding)!, options: .MutableLeaves, error:&err1 ) as! NSDictionary!
println("\(json2)")
}
答案 0 :(得分:0)
从上面的代码看来,您的数据似乎正在json2变量中保存。要从该变量中检索值,您可以尝试这样的操作。
var userName: String?
var userAge: Int?
var userEmail: String?
if let parseJSON = json2
{
userName = parseJSON["name"] as? String
userAge = parseJSON["age"] as? Int
userEmail = parseJSON["email"] as? String
}
如果返回的JSON看起来像这样,上面的内容就可以了:
{
"name": "John"
"age": "21"
"email": "john@gmail.com"
}
