我有一个如下的json响应:
[
{
"item_id": 3310,
"sku": "BWBCL14KWGF003-BWBCL14KWGF003",
"qty": 1,
"name": "BWBCL14KWGF003",
"price": 471,
"product_type": "simple",
"quote_id": "4246",
"product_option": {
"extension_attributes": {
"custom_options": [
{
"option_id": "23243",
"option_value": "625080"
},
{
"option_id": "23242",
"option_value": "625032"
}
]
}
}
}
]
我有用于获取此响应的alamofire代码。
AF.request("https://adamas-intl.com/rest/V1/carts/mine/items", method: .get, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
switch response.result {
case .success(let json):
if let res = json as? [[String: Any]]{
print("res is",res)
}
case let .failure(error):
print(error)
}
我需要从response.This的方式获取item_id和其他值,我不能到达这些值的内部。我如何解析这个json响应?

我认为这里最好的方法是使用Decodable
协议。
struct Item: Decodable {
var itemId: Int
var sku: String
// ...
}
然后使用responseDecodable(_:)
方法
// create a decoder to handle the `snakeCase` to `camelCase` attributes
// thanks to this `Decoder`, you are able to add a property `var itemId: Int` instead of `var item_id: Int`
let decoder: JSONDecoder = {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
return decoder
}()
AF.request("https://adamas-intl.com/rest/V1/carts/mine/items")
.validate()
.responseDecodable(of: [Item].self, decoder: decoder) { (response) in
guard let items = response.value else { return }
// do what you want
}
