【问题描述】：

我需要创建一个用于从 API REST 发送的 json：

  "ownId": "seu_identificador_proprio",
  "amount": 
    "currency": "BRL",
    "subtotals": 
      "shipping": 1000
    
  ,
  "items": [
    
      "product": "Descrição do pedido",
      "quantity": 1,
      "detail": "Mais info...",
      "price": 1000
    
  ],
  "customer": 
    "ownId": "seu_identificador_proprio_de_cliente",
    "fullname": "Jose Silva",
    "email": "[e-mail]",
    "birthDate": "1988-12-30",
    "taxDocument": 
      "type": "CPF",
      "number": "22222222222"
    ,
    "phone": 
      "countryCode": "55",
      "areaCode": "11",
      "number": "66778899"
    ,
    "shippingAddress": 
      "street": "Avenida Faria Lima",
      "streetNumber": 2927,
      "complement": 8,
      "district": "Itaim",
      "city": "Sao Paulo",
      "state": "SP",
      "country": "BRA",
      "zipCode": "01234000"
    
  

我对创作感到困惑..

我尝试以[NSObject:AnyObject]开头

    var d1 : [NSObject:AnyObject] = ["ownId":"seu_identificador_proprio", "customer":""]
    let dd1 = ["currency":"BRL"]
    let dd2 = ["shipping":"1000"]
    let arr = [d1]
    let d = try! NSJSONSerialization.dataWithJSONObject(arr, options: NSJSONWritingOptions.PrettyPrinted)
    let s = NSString(data: d, encoding: NSUTF8StringEncoding)! as String
    print(s)

但我需要帮助！

【问题讨论】：

你用的是swift 3吗？

不，swift 2.3 @dirtydanee

那么你的问题是什么？您发布的代码有什么问题？ （顺便说一句，除了测试将您的 JSON 输出从 NSData 转换为字符串之外，没有其他理由，也没有理由使用漂亮的打印格式。要发送到 RESTful 服务器，您不应该使用漂亮的格式。）

您的代码在我看来不错，您的打印输出是什么？

对我很好。您也可以查看SwiftyJSON too.

【参考方案1】：

我已经更新了您的代码并添加了一些提示，您如何构建上面列出的结构。编码愉快！

 // Do not use NSObject as key's type
 // Keys in a dictionary are usually Strig in every language
 var d1: [String: AnyObject] = ["ownId":"seu_identificador_proprio", "customer":""]

 // Define the type of your dictionaries, if you dont, in this case it will create a [String:String] dictionary, but you need to insert an array into it
 // Make it a var, so you can mutate the container
 var dd1: [String: AnyObject] = ["currency":"BRL"]
// Here the type is undefined. Try inserting anything else than String, and see the results
let dd2 = ["shipping":"1000"]
dd1["subtotals"] = dd2
d1["amount"] = dd1
// Build all your dictionaries like i did above, and at the end add all of them into arr
let arr = [d1]   
// Do not force try any throwing function in swift - if there is an error, your application will crash
// Use proper error handling - https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/ErrorHandling.html

do 
 let d = try NSJSONSerialization.dataWithJSONObject(arr, options: NSJSONWritingOptions.PrettyPrinted)
 let s = NSString(data: d, encoding: NSUTF8StringEncoding)! as String
 print(s)
 catch 
// Do your error handling here

我了解你的代码，现在我将为我的应用程序自定义，谢谢，如果我有其他问题，我在这里发布！

请勿在此处发布！我不确定，我怎么会有时间。然而，社区很大，我相信有人会回答你的问题。
