我正在尝试使用xcode的switf 4来使用其余的Web服务,这是我的代码:
doFilter
这是我在xcode控制台中的答案:
Linea 50:错误域= NSCocoaErrorDomain代码= 3840“无效值 字符0附近。“ UserInfo = {NSDebugDescription =无效的值 字符0。} Linea 52:可选(“ | {\” login \“:\” true \“}”)
这是我的代码Web服务:
func login_crm(user:String, passwd:String) {
let url = URL(string: "https://intranet.jytcolombia.com/ws/ws_ios/iosws_login.php?par1=\(user)&par2=\(passwd)")
let request = URLRequest(url: url!)
let task = URLSession.shared.dataTask(with: request){data, response, error in
guard let data = data else{
print("Linea 33 \(error)")
return
}
do{
print("Recibimos respuesta")
if let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String: String] {
DispatchQueue.main.async {
let result = json["login"]
if(result == "true"){
let result = json["login"]
if(result == "true"){
} else {
let alert = UIAlertController(title: "Inicio de Sesion", message: "Usuario o contraseña invalidos", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alert, animated: true, completion: nil)
}
} else {
let alert = UIAlertController(title: "Inicio de Sesion", message: "Usuario o contraseña invalidos", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alert, animated: true, completion: nil)
}
}
}
}catch let parseError{
print("Linea 50: \(parseError)")
let responseString = String(data: data, encoding: .utf8)
print("Linea 52: \(responseString)")
}
}
task.resume()
}

我可以看到您的响应字符串包含|。字符:
"|{\"login\":\"true\"}"
这会导致json解析问题。请检查您的服务器代码。
