Alamofire swift 3中的JSON.dictionaryObject为空

Alamofire swift 3中的JSON.dictionaryObject为空,json,swift,alamofire,swifty-json,Json,Swift,Alamofire,Swifty Json,我有一个JSON,格式如下: postJson ={"firstname":"Vishal","lastname":"raskar","username":"vishal123","password":"123456","confirmpassword":"123456","email":"raskarvishal7@gmail.com","timezone":"1","accountid":"12345","phoneno":"8655012753"} (postJson的数据类型为JSON

我有一个JSON,格式如下:

postJson ={"firstname":"Vishal","lastname":"raskar","username":"vishal123","password":"123456","confirmpassword":"123456","email":"raskarvishal7@gmail.com","timezone":"1","accountid":"12345","phoneno":"8655012753"}
(postJson的数据类型为JSON,即swiftyJSON)

现在我想通过Alamofire访问服务器,所以我需要在
参数中以字典格式发布JSON数据:\uuuuuuuuuu
,例如:

Alamofire.request(URL, method: .post, parameters: postJson.dictionaryObject, encoding: JSONEncoding.default,headers: "Content-Type": "application/json").responseJSON { response in switch response.result {

case .success(let data):

case .failure(let error):

}
因此,基本上我试图通过
postJson.dictionaryObject
在字典中转换JSON。但是总是从
postJson.dictionaryObject
获取null(即使数据存在于
postJson
中)

我尝试了所有组合,如
postJson.dictionaryValue
postJson.dictionary
,但没有成功

然后我尝试将
postJson
转换为
Data
,然后使用字典:

if let data = postJson.data(using: .utf8) {

 do {

return try JSONSerialization.jsonObject(with: data, options: []) as? [String: AnyObject]
            } 
catch {

 print(error.localizedDescription)

 }

 }

然后通过Alamofire发布,现在得到回复。我做错了什么?我想使用我的第一个选项。

假设您使用的是Swift 3/Alamofire 4.0

以下是根据Alamofire文档定义“参数”参数的方式:

let parameters: Parameters = ["foo": "bar"]

Alamofire.request(urlString, method: .get, parameters: parameters, encoding: JSONEncoding.default)
    .downloadProgress(queue: DispatchQueue.global(qos: .utility)) { progress in
        print("Progress: \(progress.fractionCompleted)")
    }
    .validate { request, response, data in
        // Custom evaluation closure now includes data (allows you to parse data to dig out error messages if necessary)
        return .success
    }
    .responseJSON { response in
        debugPrint(response)
    }
要了解更多信息,您可以直接使用
[“firstname”:“Vishal”,“lastname”:“raskar”,“username”:“vishal123”,“password”:“123456”,“confirmpassword”:“123456”,“email”:raskarvishal7@gmail.com“,”时区“:”1“,”帐户ID“:”12345“,”电话号码“:”8655012753”]
作为请求的参数,无需将其转换为swiftyjson对象。
