使用 nsurlconnection 请求 php 脚本 - Request on php script with nsurlconnection

Request on php script with nsurlconnection

我尝试使用此代码将值发送到服务器，我在此行上出现错误：

let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error: &error)

错误

是：调用"错误"中的额外参数

var yourUrl="mylink"
let url = NSURL(string:yourUrl)
let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 2.0)
request.HTTPMethod = "POST"
// set Content-Type in HTTP header
let boundaryConstant = "
V2ymHFg03esomerandomstuffhbqgZCaKO6jy";
let contentType = "multipart/form-data; boundary=" + boundaryConstant
NSURLProtocol.setProperty(contentType, forKey: "Content-Type", inRequest: request)
// set data
var dataString = "my value"
let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
request.HTTPBody = requestBodyData
var response: NSURLResponse? = nil
var error: NSError? = nil
let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error: &error)
let results = NSString(data:reply!, encoding:NSUTF8StringEncoding)
if let dataFromString = results!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
let json = JSON(data: dataFromString)

if(json=="0"){
print("'n Dati non validi");
}
else{
print("'n Account creato");
}
}

你永远不应该使用 sendSyncRequest，因为它是一个阻塞调用。此外，从iOS 9.0开始，它已被弃用。相反，您可以使用 NSURLSession。尝试以下代码

var yourUrl="mylink"
let URL = NSURL(string:yourUrl)
let request:NSMutableURLRequest = NSMutableURLRequest(URL: URL)
let boundaryConstant = "V2ymHFg03esomerandomstuffhbqgZCaKO6jy";
let contentType = "multipart/form-data; boundary=" + boundaryConstant
NSURLProtocol.setProperty(contentType, forKey: "Content-Type", inRequest: request)
var dataString = "my value"
request.HTTPMethod = "POST"
request.HTTPBody = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
    //reponse recieved
    //in this case response string will be saved in data, its of type NSData
    do{
         let str = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as! [String:AnyObject]
         print(str)
    }
    catch {
         print("json error: '(error)")
    }
    })
task.resume()
