Question

我将结果作为像这样的字符串数组

["India","America","Australia","China","Russia"]

我正在使用 Alamofire 来使用代码获取响应。没有错误，但我得到的结果为null。请帮助解析这个。

sessionManager?.request(strURL, method: method, parameters: params, encoding: encoding , headers: headers).responseJSON { (response) in
   switch response.result {
        case .success:
            let resJson = JSON(response.result.value!)
           success(resJson)
            break
        case .failure(let error):
            failure(error as NSError)
            break
        }

    }

Answer 1

试试这个：

if let responseData = response.result.value{    
let responsevalue = responseData  as? [String]
}

Answer 2

对于寻找另一个派生答案的人，只需将这段代码放在Alamofire.request(...)之后：

.responseJSON(completionHandler: { (response) in

            switch response.result{

            case .success(let value):

                // Here is your array of String
                let arrayOfStrings = value as? [String]

            case .failure(let error):

                // Some code when error happens...
                print(error.localizedDescription)

            }

        })

Answer 3

使用SwiftyJSON的此解决方案：

.responseJSON(completionHandler: { (response) in

     switch response.result{
     case .failure(let error):
         print(error.localizedDescription)

     case .success(let res):
       let json = JSON(res)
       let res = json["result"]

       var models = [String]()
       if let models1 = company["models"].array {
           for model in models1 {
               guard let mod = model.string else { return }
               models.append(mod)
           }
       }
     }
})
