iOS Swift Alamofire POST請(qǐng)求報(bào)錯(cuò)Code=-1002

Swift請(qǐng)求代碼：

import Alamofire
let parameters:[String : Any] = [
    "action": "login",
    "login": "admin",
    "password": "admin"
]

let urlString = "localhost:8888/index.php"

Alamofire.request(urlString, method: .post, parameters: parameters).responseJSON { response in
    switch response.result.isSuccess {
    case true:
        print("數(shù)據(jù)獲取成功!")
    case false:
        print(response.result.error!)
    }
}
