我正在做一些快速的Web服務。我正在使用alamofire。代碼正在工作,但我認爲它不「可讀」(不是乾淨的代碼)。你有一個想法,我可以優化這個?由於避免快速嵌套,如果讓測試
static func checkBookValidity(serialNumber: String, callBack: Result<Bool?> ->()) {
let router = Router.CheckBookLuggage(serialNumber: serialNumber)
let request = Alamofire.request(router)
request.validate()
request.response { (request, response, data, error) in
if let error = error {
if error.code == NSURLErrorNotConnectedToInternet {
callBack(.Failure(.NoConnection))
}
else {
if let data = data {
do
{
if let json = try NSJSONSerialization.JSONObjectWithData(data, options: .AllowFragments) as? [String : AnyObject] {
let erroType = WSError.errorTypeWithJson(json, httpErroCode: error.code)
callBack(.Failure(erroType))
}
} catch {
callBack(.Failure(.ServerError))
}
}
else {
callBack(.Failure(.ServerError))
}
}
}
else {
if let data = data {
do
{
if let json = try NSJSONSerialization.JSONObjectWithData(data, options: .AllowFragments) as? [String : AnyObject] {
if let resultDic = json["result"] as? [String:AnyObject], let exists = resultDic["exists"] as? Bool {
if exists {
if let owner = resultDic["email"] as? String {
// ...
}
}
else {
callBack(.Success(false))
}
}
}
} catch {
callBack(.Failure(.ServerError))
}
}
}
}
}

您應該可以在http://codereview.stackexchange.com/上提出這個問題, – kye
謝謝,我知道警衛聲明:)。你有一個想法,如果我可以使用衛兵梳理可選的綁定和調用功能, (當試圖解析json並綁定「數據」時,請參閱我的示例) – samir
