Alamofire 5：“Result<Data, AFError>”类型的值没有成员“value”

Question

是 Alamofire 5 中的新错误吗？因为上次没有遇到错误。下面是完成的代码。任何使用 Alamofire 的人都面临这个问题？

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)
    }
  }
}

您必须提取如下result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)!)
            completion(try? SomeRequest(protobuf: value))
        case .failure(let error):
            print(error)
            completion(nil)
        }
    }
}
