Discussion 1: EXC_BREAKPOINT (code = 1, subcode = 0x10136bb50) - rapide

Question

J'ai eu cette erreur quand je veux envoyer la valeur avec la méthode GET:

Discussion 1: EXC_BREAKPOINT (code = 1, subcode = 0x10136bb50)

Pour obtenir des valeurs:

var flname  = self.txt_field_flname.text 
var job_title = self.txt_field_job_title.text 
var mobile  = self.txt_field_mobile.text 
var des   = self.txt_field_des.text 
var lat   = self.lat 
var lon   = self.lon 

self.sendNewJob(fname: flname!, title: job_title!, mobile: mobile!, des: des!, lat: String(lat), lon: String(lon)) 

---

func sendNewJob(fname:String,title:String,mobile:String,des:String, 
       lat:String,lon:String) 
{ 
    print("fname \(fname) title \(title) mobile \(mobile) des \(des) lat \(lat) lon \(lon)") //output is well 

    RestApiManager.sharedInstance.sendNewJob(fname: fname,title: title,mobile:mobile, 
              des:des,lat:lat,lon:lon) { (json: JSON) in 

    } 
} 

---

func sendNewJob(fname:String,title:String,mobile:String,des:String, 
       lat:String,lon:String,onCompletion: @escaping (JSON) -> Void) { 
    let route = baseURL+"up=1&Name=\(fname)&BusinessName=\(title)&MobileNumber=\(mobile)&latitude=\(lat)&longitude=\(lon)&Description=\(des)" 
    makeHTTPGetRequest(path: route, onCompletion: { json, err in 
     onCompletion(json as JSON) 
    }) 
} 


// MARK: Perform a GET Request 
private func makeHTTPGetRequest(path: String, onCompletion: @escaping ServiceResponse) { 
    let request = NSMutableURLRequest(url: NSURL(string: path)! as URL) // line of my error 

    let session = URLSession.shared 

    let task = session.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in 
     if let jsonData = data { 
      let json:JSON = JSON(data: jsonData) 
      onCompletion(json, error as NSError?) 
     } else { 
      onCompletion(nil, error as NSError?) 
     } 
    }) 
    task.resume() 
} 

Answer 1

Cela se produit lorsque le code exécute une valeur nulle. Voici le code NSURL (string: path)! la valeur pourrait être nulle. Vous pouvez utiliser la liaison facultative (si let) pour vérifier si le NSURL est valide. Cela arrive quand la chaîne n'est pas valide et ne fait pas une URL valide.

Answer 2

Vous pouvez utiliser comme ceci:

private func makeHTTPGetRequest(path: String, onCompletion: @escaping ServiceResponse) { 
    if let encodedPath = path.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) { 
     if let url = URL(string: encodedPath) { 
      let request = URLRequest(url: url) 
      let session = URLSession.shared 
      let task = session.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in 
       if let jsonData = data { 
        let json:JSON = JSON(data: jsonData) 
        onCompletion(json, error as NSError?) 
       } else { 
        onCompletion(nil, error as NSError?) 
       } 
      }) 
      task.resume() 
     } else { 
      print("url is nil") 
      onCompletion(nil) 
     } 
    } else { 
     print("unable to encode url") 
     onCompletion(nil) 
    } 
}
