形成卷曲后使用JSON数据作为迅速HTTP POST

Question

我有卷曲后，我想变成在迅速一个HTTP URL请求：

卷曲后（命令行）：

curl -X POST --header "Content-Type:application/json" --header "Authorization:key=SERVER_KEY" "https://gcm-http.googleapis.com/gcm/send" --data-ascii '{"to":"DEVICE_TOKEN","data":{"uid":"USER_ID"},"priority":10,"notification":{"body":"Hello","badge":"2"}}' 

HTTP请求（SWIFT）：

var request = URLRequest(url: URL(string: globalClass.getAppDelegate().global.sendUrl)!) 
     request.httpMethod = "POST" 

var bodyData:String! 

bodyData = "title=\(title)&body=\(message)&user_id=\(user_id)" 

request.httpBody = bodyData.data(using: .utf8) 

let task = URLSession.shared.dataTask(with: request) 

我怎么把数据部分到HTTP请求的bodyData？

"data":{"uid":"USER_ID"} 

我不知道如何形成它，因为它是一个嵌套结构。

转换为词典：

let title = "somthing" 
let body = "body text" 
let params = ["title":mail, "body": pass] as Dictionary<String, String> 

转换字典以JSON：

do { 
     request.HTTPBody = try NSJSONSerialization.dataWithJSONObject(params, options: []) 
    } catch { 
     print("Error") 
    } 

添加页眉

request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
request.addValue("application/json", forHTTPHeaderField: "Accept") 
request.addValue(serverKey, forHTTPHeaderField: "Authorization") 

编辑：

转换这个JSON来解释：

"notification":{"body":"Hello","badge":"3"}

let notification = ["body": "Hello", "badge":"3"] 
let data: [String: AnyObject] = ["notification": notification as AnyObject]
