Question

我有这样的可编码模型

struct Payment: Codable {
  var id: Int?
  var date: String?
  var companyId: Int?
  var companyName: String?
  var dueDate: String?
  var amount: Int?
  var paidOrNot: Bool?
  var paidDate: String?
  var returnAmount: Int?
  var paidAmount: Int?
  var createdAt: String?
  var updatedAt: String?
}

当我从字典中打印编码数据时，我的httpBody中有可选内容。

Payment(id: nil, date: Optional("Nov 23, 2018"), companyId: nil, companyName: Optional(""), dueDate: Optional("Nov 23, 2018"), amount: Optional(5), paidOrNot: Optional(true), paidDate: Optional("Nov 23, 2018"), returnAmount: Optional(0), paidAmount: Optional(5), createdAt: nil, updatedAt: nil)

Answer 1

当您编写var id：Int ？时，这使您的Integer类型成为可选，这仅意味着如果检测到该类型为空，则程序将不会结束

使用Codable Model编码可选值？
