GraphSQL 突變會產生以下錯誤。我附上了我的查詢和代碼。
GraphQLResult<Data>(data: nil, errors: Optional([Validation error of type UnknownType: Unknown type TicketType, Validation error of type FieldUndefined: Field 'addTicket' in type 'Mutation' is undefined @ 'addTicket']), extensions: nil, source: Apollo.GraphQLResult<MyProject.MyMutation.Data>.Source.server, dependentKeys: nil)
詢問：
mutation MyMutation($id: String!, $ticketType: TicketType) {
addTicket(input: { id: $id, ticketType: $ticketType}) {
accountId
storyId
}
}
在 API.swift 中，這個 Enum 是從 schema.json 檔案自動生成的。
public enum TicketType: RawRepresentable, Equatable, Hashable, CaseIterable, Apollo.JSONDecodable, Apollo.JSONEncodable {
public typealias RawValue = String
case normal
case firstClass
case secondClass
/// Auto generated constant for unknown enum values
case __unknown(RawValue)
public init?(rawValue: RawValue) {
switch rawValue {
case "NORMAL": self = .normal
case "FIRST_CLASS": self = .firstClass
case "SECOND_CLASS": self = .secondClass
default: self = .__unknown(rawValue)
}
}
public var rawValue: RawValue {
switch self {
case .normal: return "NORMAL"
case .firstClass: return "FIRST_CLASS"
case .secondClass: return "SECOND_CLASS"
case .__unknown(let value): return value
}
}
public static func == (lhs: TicketType, rhs: TicketType) -> Bool {
switch (lhs, rhs) {
case (.normal, .normal): return true
case (.firstClass, .firstClass): return true
case (.secondClass, .secondClass): return true
case (.__unknown(let lhsValue), .__unknown(let rhsValue)): return lhsValue == rhsValue
default: return false
}
}
public static var allCases: [TicketType] {
return [
.normal,
.firstClass,
.secondClass,
]
}
}
在我的代碼中，我按如下方式呼叫此方法
myNetworkObj.apollo.perform(mutation: addTicket(id: "1234", ticketType: .normal) {
result in ....
}
uj5u.com熱心網友回復：
我不相信你的直接問題是列舉，而是你如何呼叫突變。
當你在客戶端呼叫它時，mutation 的引數簽名需要匹配 schema：
mutation: addTicket(input{id: "1234", ticketType: .normal})
addTicket的頂級引數input在您的架構中。
