Alamofire 5：类型'Result '的值没有成员'值'

Question

Alamofire 5中是否有新错误？因为这上次没有遇到错误。下面是完成的代码。任何使用Alamofire的人都面对过吗？

import Foundation
import Alamofire

class MyAppService {
static let shared = MyAppService()
let url = "http://127.0.0.1:5000"

private init() { }

func getCurrentUser(_ completion: @escaping (SomeRequest?) -> ()) {
    let path = "/somePath"
    AF.request("\(url)\(path)").responseData { response in
        if let data = response.result.value { //error shown here (Value of type 'Result<Data, AFError>' has no member 'value')
            let contact = try? SomeRequest(protobuf: data)
            completion(contact)
        }
        completion(nil)
    }
  }
}

您必须按如下所示提取结果值，

func getCurrentUser(_ completion: @escaping (SomeRequest?) -> ()) {
    let path = "/somePath"
    AF.request("\(url)\(path)").responseData { response in
           switch response.result {
           case .success(let value):
                print(String(data: value, encoding: .utf8)!)
                let contact = try? SomeRequest(protobuf: value)
                completion(contact)
           case .failure(let error):
               print(error)
               completion(nil)
           } 
        }
  }
}
