Question

我正在服务器上发送关注数据

params =  ["product": [["product_id": 1, "quantity": 6], ["product_id": 3, "quantity": 7], ["product_id": 4, "quantity": 1]]]

Alamofire.request("http://localhost/info-c.php", method:.post, parameters: params , headers:  getHeaderForLoggInUser() ).responseJSON { response in
                DispatchQueue.main.async(execute: {() -> Void in
                    switch response.result {
                    case .success:
                        if let json = JSON(response.result.value ?? [:]).dictionary{
                            print(json)
                            completed(json)
                        }else{
                            dError( "Internal server Error")
                        }
                        break
                    case .failure(let er):
                        dError( "Internal server Error \(er)")
                        break
                    }
                })
            }

但是在服务器端，我的身份是：

["product": [
  {
    "product_id" : "1"
  },
  {
    "quantity" : "6"
  },
  {
    "product_id" : "3"
  },
  {
    "quantity" : "7"
  },
  {
    "product_id" : "4"
  },
  {
    "quantity" : "1"
  }
]]

我也尝试过

encoding: JSONEncoding.default,

然后我得到

["{\"product\":": {
  "{\"product_id\":1,\"quantity\":6},{\"quantity\":7,\"product_id\":3},{\"product_id\":4,\"quantity\":1}" : ""
}]

我的API所需的输入格式如下：
产品[0] [产品ID]：1
产品[0] [数量]：6
产品[1] [产品ID]：2
产品[1] [数量]：6

创建模型

struct Product {
    var product_id: Int
   var quantity : Int
}

从应用中填充模型-基于选择

let product = Product.init(product_id: 1, quantity: 6)
let product1 = Product.init(product_id: 2, quantity: 3)
let product2 = Product.init(product_id: 4, quantity: 1)

arrayProducts.append(product)
arrayProducts.append(product1)
arrayProducts.append(product2)

在调用服务器之前-根据服务器要求设置参数。

    var parameters = [String: Any]()

    for (index, element) in arrayProducts.enumerated() {
        let dynamicProductIDKey = "product[\(index)][product_id]"
        let dynamicProductIDValue = element.product_id

        let dynamicProductQuantityKey = "product[\(index)][quantity]"
        let dynamicProductQuantityValue = element.quantity

        parameters[dynamicProductIDKey] = dynamicProductIDValue
        parameters[dynamicProductQuantityKey] = dynamicProductQuantityValue

    }

现在您可以将参数共享给服务器。

谢谢

Answer 2

尝试以下字典

let dict = [
    "product[0][product_id]" : "1",
    "product[0][quantity]" : "6",
    "product[1][product_id]" : "2",
    "product[1][quantity]" : "6",
]

Alamofire在发送请求时拆分嵌套对象
