无法将jsonArray元素转换为整数 [英] Cannot convert jsonArray element to integer

问题描述

do{
    let resultJSON = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions())
    let arrayJSON = resultJSON as! NSArray

    let success:NSInteger = arrayJSON["success"] as! NSInteger

    if (success == 1 ) ....

json数据是来自服务器的响应，我试图将其转换为整数，但出现对话错误.

json data is the response from the server, i am trying to convert it to integer but i get the conversation error.

推荐答案

这是一个有效的实例(在我的计算机上经过测试)

This is a working exmaple (tested on my machine)

let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in

            if let error = error {
                print(error)
            }
            if let data = data{
                print("data =\(data)")
                do{
                let resultJSON = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions())
                let resultDictionary = resultJSON as? NSDictionary

                    let success = resultDictionary!["success"]!
                    let successInteger = success as! Int
                    print("success = \(success)")
                    if successInteger == 1 {
                        print("yes")
                    }else{
                        print("no")
                    }
                }catch _{
                    print("Received not-well-formatted JSON")
            }

            }
            if let response = response {
                print("url = \(response.URL!)")
                print("response = \(response)")
                let httpResponse = response as! NSHTTPURLResponse
                print("response code = \(httpResponse.statusCode)")
            }



        })
        task.resume()

响应为:

{ "error_message" : "No User", "success" : 0}

注意

您说您的服务器响应为:

Note

you said that your server responnes as:

{ "error_message" = "No User"; success = 0; } 

这不是不是有效的json，您应该更正它以匹配我给您的json

and this is not a valid json, you should correct it to match the json that i gave to you
