Alamofire automatic validation

Sometimes, you will want to use Alamofire automatic validation for some requests. When a request is configured with Alamofire validation, Moya will internally call Alamofire's validate() method on the concerned DataRequest.

// MARK: - TargetType Protocol Implementation
extension MyService: TargetType {
    var baseURL: URL { return URL(string: "https://api.myservice.com")! }
    var path: String {
        switch self {
        case .zen:
            return "/zen"
        case .showUser(let id):
            return "/users/\(id)"
        case .createUser:
            return "/users"
        case .showAccounts:
              return "/accounts"
        }
    }
    
    // Other needed configurations
    // ...
    
    // Validate setup is not required; defaults to `false`
    // for all requests unless specified otherwise.
    var validate: Bool {
        switch self {
        case .zen, .showUser, .showAccounts:
            return true
        case .createUser(let firstName, let lastName):
            return false
        }
    }
}

Alamofire automatic validation can be useful, for example if you want to use the Alamofire's RequestRetrier and RequestAdapter, for an OAuth 2 ready Moya Client.

Also, if validation fails, you can get the response from the returned MoyaError.

provider.request(target) { result in
    ...
    if case let .failure(error) = result {
        response = error.response
        // Do something with the response
    }
    ...
}
