Question

我正在使用Moya创建API层，并在创建端点请求时继续为.updateMyWeightGoal目标获取上述错误。

    goalAPI.request(target:  .updateMyWeightGoal(weightGoalData: goalInfo),  success: { (response) in
        //
    }){ (response: [String : Any]) in
        print(response)
    }

我已经创建了另一个相同类型的Moya API，并使用与此相同的goalAPI来调用它，并且它工作正常。

任何可能导致此问题的想法

此处的参考是weightGoalData类型

的类定义

class UpdatedWeightGoalInfo: Mappable {

var consumerUserID: Int?
var height: String?
var weight: String?
var goalWeight: String?

init() {

}

convenience init(userId: Int, weightGoalData: WeightGoalResponse) {
    self.init()
    consumerUserID = userId
    height = "\(weightGoalData.currentHeight)"
    weight = "\(weightGoalData.currentWeight)"
    goalWeight = "\(weightGoalData.goalWeight)"
}

required init?(map: Map) {
}

func mapping(map: Map) {
    consumerUserID <- map["consumerUserId"]
    height <- map["height"]
    weight <- map["weight"]
    goalWeight <- map["goalWeight"]
}
}

API的定义：

enum GoalSettingAPI: AccessTokenAuthorizable {

  case updateMyWeightGoal(weightGoalData: UpdatedWeightGoalInfo)
}

extension GoalSettingAPI: TargetType {
var parameterEncoding: ParameterEncoding {
    switch self {
    default:
        return JSONEncoding.default
    }
}

var baseURL: URL { return URL(string: appBaseURL + "*hidden*/")! }
var path: String {
    switch self {
    case .updateMyWeightGoal(_):
        return "updateMyWeightGoal"
    }
}

var method: Moya.Method {
    switch self {
    case .updateMyWeightGoal(_):
        return .post
    }
}

var parameters: [String: Any]? {
    switch self {
    case .updateMyWeightGoal(let weightGoalData):
        return weightGoalData.toJSON()
    }
}

var sampleData: Data {
    switch self {
    default:
        return Data()
    }
}

var task: Task {
    switch self {
    default:
        return .request
    }
}

var shouldAuthorize: Bool {
    switch self {
    default:
        return false
    }
}
}

Answer 1

这是最愚蠢的事情。

事实证明错误来了，不是来自枚举，而是来自成功块。它期待一个Mappable类型的对象，我没有提供。

Answer 2

当您将.updateMyWeightGoal声明为枚举时，您将其称为实例成员（.）。尝试更改：

goalAPI.request(target: .updateMyWeightGoal(weightGoalData: goalInfo)

要

goalAPI.request(target: GoalSettingAPI.updateMyWeightGoal(weightGoalData: goalInfo)

Answer 3

有相同的错误。就我而言，问题是我输入了以下内容：

if someVariable = .AnEnumValue

我的意思是：

if someVariable == .AnEnumValue

关键区别在于=与==。

不确定编译器如何处理此特定错误消息，但这可以解决问题。

枚举元素不能作为实例成员引用
