解析Alamofire结果到Swift中的对象（使用：Alamofire，SwiftyJSON和ObjectMapper）

Question

解析传入的JSON时出现问题。

这是我的函数：

func postCheckUserPhonenumbers(phonenumbers:[String], completionHandler: (([AnyObject?], AnyObject?) -> Void)) { 
     let urlString = Constant.apiUrl().stringByAppendingFormat(Constant.apiPostCheckUserPhonenumbers) 

     let phoneNumbersDictionary = phonenumbers.map({ ["number": $0] }) 

     let JSON = try? NSJSONSerialization.dataWithJSONObject(phoneNumbersDictionary, options: []) 

     let request = NSMutableURLRequest(URL: NSURL(string: urlString)!) 
     request.setValue("application/json", forHTTPHeaderField: "Content-Type") 
     request.HTTPMethod = "POST" 
     request.HTTPBody = JSON 

     Alamofire.request(request).validate().responseJSON(completionHandler: {response in 
      if response.result.isSuccess{ 
       if let value = response.result.value { 
//     let json = JSON(value) 
        if let users:Array<User> = Mapper<User>().mapArray(value) { 
         completionHandler(users, nil) 
        } else { 
         completionHandler([nil], nil) 
        } 
       } 
      } 
      if response.result.isFailure{ 
       let message = ApiMessage() 
       message.message = "No users found" 
       completionHandler([nil],message) 
      } 
     }) 
    } 

通常我把结果成JSON第一，但尝试这样做，每当这个时候，我得到的编译错误：

这确实是我在函数上面声明的JSON变量。现在我有这样的：

func postCheckUserPhonenumbers(phonenumbers:[String], completionHandler: (([AnyObject?], AnyObject?) -> Void)) { 
    let urlString = Constant.apiUrl().stringByAppendingFormat(Constant.apiPostCheckUserPhonenumbers) 

    let phoneNumbersDictionary = phonenumbers.map({ ["number": $0] }) 

    let inputJSON = try? NSJSONSerialization.dataWithJSONObject(phoneNumbersDictionary, options: []) 

    let request = NSMutableURLRequest(URL: NSURL(string: urlString)!) 
    request.setValue("application/json", forHTTPHeaderField: "Content-Type") 
    request.HTTPMethod = "POST" 
    request.HTTPBody = inputJSON 

    Alamofire.request(request).validate().responseJSON(completionHandler: {response in 
     if response.result.isSuccess{ 
      if let value = response.result.value { 
       let json = JSON(value) 
       let jsonString = json.rawString() 
       if let users:Array<User> = Mapper<User>().mapArray(jsonString) { 
        completionHandler(users, nil) 
       } else { 
        completionHandler([nil], nil) 
       } 
      } 
     } 
     if response.result.isFailure{ 
      let message = ApiMessage() 
      message.message = "No users found" 
      completionHandler([nil],message) 
     } 
    }) 
}
