如何使用Swift Moya测量响应时间？

import Moya

let provider = MoyaProvider<YourAPI>()

enum YourAPI {
    case getUser(id: Int)
    // 其他请求...
}

extension YourAPI: TargetType {
    var baseURL: URL {
        return URL(string: "https://api.example.com")!
    }
    
    var path: String {
        switch self {
        case .getUser(let id):
            return "/user/\(id)"
        // 其他请求...
        }
    }
    
    var method: Moya.Method {
        return .get
    }
    
    var task: Task {
        return .requestPlain
    }
    
    var headers: [String: String]? {
        return nil
    }
}

let startTime = DispatchTime.now()

provider.request(.getUser(id: 1)) { result in
    let endTime = DispatchTime.now()
    let responseTime = endTime.uptimeNanoseconds - startTime.uptimeNanoseconds
    print("Response time: \(responseTime) nanoseconds")
    
    switch result {
    case .success(let response):
        // 处理成功响应
    case .failure(let error):
        // 处理错误
    }
}
