如何将 poststring 写入 API swift3

Question

我是新来的。如何编写下面的代码并将其转换为 postString，因为我需要提交给 API。

{
    "service": 0,
    "size": "string",
    "orderReference": "string",
    "dropOffHubId": "string",
    "pickUpHubId": "string",
    "courierId": "string",
    "from": {
        "address": {
            "address1": "string",
            "address2": "string",
            "city": "string",
            "postcode": "string",
            "state": "string",
            "country": "string"
        }
    },
    "to": {
        "name": "string",
        "phone": "string",
        "email": "string",
        "address": {
            "address1": "string",
            "address2": "string",
            "city": "string",
            "postcode": "string",
            "state": "string",
            "country": "string"
        }
    }
}

这样写对吗，但是"from"后面的字符串怎么写：{还有"address": { 然后进入 "address1": "string", 然后另一个是 "to": { "name": "string", 然后进去 "address": {, 然后进去 "address1": "string",

let postString = [ "service": 0,
                   "size": "string",
                   "orderReference": "string",
                   "dropOffHubId": "string",
                   "pickUpHubId": "string",
                   "courierId": "string",
                   "from": "fromAddArr",
                   "to": "toAddArr"] as [String : Any]
var request = URLRequest(url:URL!)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue(bearerToken!, forHTTPHeaderField: "Authorization")
request.httpBody = try! JSONSerialization.data(withJSONObject: postString, options:.prettyPrinted)

我只知道这样写

{
  "refNo": "string",
  "code": "string"
}

let postString = ["refNo": "string",
                          "code": "string"]

试试这个我想你想要这样的东西：首先从当前 json 中获取地址字典并将该字典转换为字符串：

let dictionary:[String:Any] = ["address": [
            "address1": "string",
            "address2": "string",
            "city": "string",
            "postcode": "string",
            "state": "string",
            "country": "string"
        ]
    ]

    if let theJSONData = try? JSONSerialization.data( withJSONObject: dictionary, options: []) {
        let theJSONText = String(data: theJSONData, encoding: .utf8)
        print("JSON string = \(theJSONText!)") //you can use this string to create dictionary as you want 
        let dict = ["addres":theJSONText!]
        print(dict)
    }

你不需要自己写那个字符串。如果您使用的是 swift 3 并且该 JSON 字符串有一个模型 class，您可以使用第三方库 here。这会将您的模型转换为字典、数组、json 字符串和数据等。您只需要使模型成为 ParsableModel 或 JSONParsable 的子模型。

如果您在从 JSON 创建模型 class 时遇到问题，您可以使用 this 实用程序。这将为您的 JSON:

生成模型 class

class RootClass {
    var courierId: String?
    var dropOffHubId: String?
    var from: From?
    var orderReference: String?
    var pickUpHubId: String?
    var service: NSNumber?
    var size: String?
    var to: To?  
}

class To {
    var address: Addres?
    var email: String?
    var name: String?
    var phone: String? 
}

class From {
    var address: Addres?  
}

class Addres {
    var address1: String?
    var address2: String?
    var city: String?
    var country: String?
    var postcode: String?
    var state: String?
}

如果您正在使用 Swift 4. 它为您提供 classes 来编码和解码您的代码，从 JSON 建模和建模到 JSON。使用这个可以节省您的时间。
