如何在带有Alamofire 5的HTTP正文中发送带有嵌套对象的POST请求，如字典数组作为参数？我未能通过JSONSerialization以正确的格式转换对象，不知道下一步该做什么吗？
我的JSON对象，它需要作为参数传递
{
"OrderProducts": [
{
"ProductId": 2,
"PrimaryModifierId": 20,
"SecondaryModifierId": 13,
"ProductBasePrice": 100,
"ProductDiscount": 10,
"Quantity": 3,
"Total": 270
},
{
"ProductId": 3,
"PrimaryModifierId": 1,
"SecondaryModifierId": 6,
"ProductBasePrice": 120,
"ProductDiscount": 10,
"Quantity": 2,
"Total": 216
}
],
"OrderDeals": [
{
"DealId": 1,
"DealPrice": 2299,
"Quantity": 3,
"Total":6897
},
{
"DealId": 2,
"DealPrice": 1299,
"Quantity": 1,
"Total":1299
}
],
"OrderDetail": {
"UserId": 5,
"PaymentMethodId": 1,
"OrderPromoCodeId": 1,
"AddressId": 12,
"ProductTotal": 700,
"DealTotal": 500,
"SubTotal": 1200,
"ShippingCharges": 300,
"Tax": 100,
"TotalPrice": 1600
},
"PaymentDetail": {
"LastFour": 1234,
"TransactionReference": "sad",
"TransactionStatus": "Aproved"
}}
我的邮政请求功能
func OrderCreate(OrderProduct:[[String:Any]] , PaymentDetail:[String:Any], OrderDetail:[String:Any], OrderDeals:[[String:Any]], completionHandler:@escaping (_ success:OrderCreateModelClass.OrderCreateModel?, Error?) -> ()){
let header : HTTPHeaders = [
Api.Params.contentType:Api.Params.applicationJSON,
Api.Params.authorization:requestManager.instance.getToken!
]
let params : [String:Any] = [
"OrderProducts" : OrderProduct ,
"OrderDeals" : OrderDeals,
"OrderDetail" : OrderDetail,
"PaymentDetail" : PaymentDetail
]
manager.request(Api.CONSTANTS_METHODS.ORDER_CREATE_API, method: .post, parameters: params, encoding: JSONEncoding.default, headers: header).responseJSON { (response) in
switch response.result {
case .success(let validResponse):
guard let res = validResponse as? [String:Any] else {return}
if ((res["flag"] as? Int) != nil) {
let data = try! JSONSerialization.data(withJSONObject: validResponse.self, options: [])
let resultObject = try! JSONDecoder().decode(OrderCreateModelClass.OrderCreateModel.self, from: data)
completionHandler(resultObject,nil)
} else {
completionHandler(nil,nil)
}
case .failure(let error):
print("FailedNot")
switch (response.response?.statusCode) {
case 404:
print("not Found")
case 401:
print("unauthorized")
case 408:
print("request timeout")
case 406:
print("Unable to format response according to Accept header")
completionHandler(nil,error)
default:
print(error.localizedDescription)
}
}
}
}获取的错误
格式糟糕的Json对象看起来如下(转换后打印)
编辑：
Func在Dilan的解决方案之后(但仍然给出相同的错误)如下所示
func OrderCreate(OrderProduct:[[String:Any]] , PaymentDetail:[String:Any], OrderDetail:[String:Any], OrderDeals:[[String:Any]], completionHandler:@escaping (_ success:OrderCreateModelClass.OrderCreateModel?, Error?) -> ()){
let header : HTTPHeaders = [

在alamofire中，我们不能转换这种json(使用嵌套数组)，directly.You应该将其对象从内到外转换为参数。
在将 OrderProduct 添加到params之前，需要循环OrderProduct数组并创建Alamofire参数对象数组，然后可以将该数组添加到param数组中，
var products:[Parameters] = [:]
OrderProduct.forEach { (product) in
let item:Parameters = [
"ProductId": product["ProductId"] as? Int ?? 0,
"PrimaryModifierId": product["PrimaryModifierId"] as? Int ?? 0,
"SecondaryModifierId": product["SecondaryModifierId"] as? Int ?? 0,
"ProductBasePrice": product["ProductBasePrice"] as? Double ?? 0,
"ProductDiscount": product["ProductDiscount"] as? Double ?? 0,
"Quantity": product["Quantity"] as? Double ?? 0,
"Total": product["Total"] as? Double ?? 0
]
products.append(item)
}有关订购详情
var orderDetails:Parameters = [
"UserId": OrderDetail["UserId"] as? Int ?? 0,
//other fields
]对其他需要的参数执行同样的操作，然后您可以使用这些预先创建的参数创建params。
let params : [String:Any] = [
"OrderProducts" : [products] ,//pre created param array
"OrderDeals" : OrderDeals,
"OrderDetail" : orderDetails, // pre created param
"PaymentDetail" : PaymentDetail
]我想你明白了
