import SwiftJSONRPC class UserService: RPCService { func vote(rating: Int) async throws -> Int { return try await invoke("vote", params: ["rating": rating]) } func create(name: String) async throws -> User { return try await invoke("create", params: ["name": name]) } // And other JSON-RPC methods }
You can define as many services as you want depending on your requirements.
// Init JSON-RPC client let url = URL(string: "http://example.com/rpc")! let client = RPCClient(url: url) // Init JSON-RPC service let service = MyService(client: client) // Perform request try await service.vote(rating: 5)
SwiftJSONRPC uses Swift's Decodable protocol to decode response objects.
struct User: Decodable { let id: String let name: String } class UserService: RPCService { func getCurrentUser() async throws -> User { return try await invoke("getCurrentUser") } } let user = try await userService.getCurrentUser() print("Current user ID = \(user.id), name = \(user.name)")
If you need to modify JSONDecoder's behaviour, use RPCClient.coder.resultDecoder for that.
client.coder.resultDecoder.dateDecodingStrategy = .iso8601
SwiftJSONRPC uses Swift's Encodable protocol to encode request params.
struct Message: Encodable { let text: String } class MessageService: RPCService { func send(message: Message) async throws { return try await invoke("sendMessage", params: message) } } let message = Message(text: "Hello World") try await messageService.send(message: message)
If you need to modify JSONEncoder's behaviour, use RPCClient.coder.paramsEncoder for that.
client.coder.paramsEncoder.dateDecodingStrategy = .iso8601
