我們請(qǐng)求時(shí)通常會(huì)創(chuàng)建一個(gè)字典然后把參數(shù)放到字典里，如

 let param:[String: Any]? = ["account" : "158xxxxxx"]
 Alamofire.request(urlStr, method: HTTPMethod.post, parameters: param, encoding: URLEncoding.queryString, headers: httpHeader).responseJSON {    (DataResponse) in
    
        }

如果后請(qǐng)求的接收方式是以post時(shí)，后臺(tái)接收方式是以 from 表單時(shí) encoding 一定要為URLEncoding.queryString。不然后臺(tái)接收不到數(shù)據(jù)
