Alamofire 5：类型为'Result< Data，AFError>'的值没有成员“值”

问题描述

Alamofire 5是否有新错误？因为上次没有遇到错误。下面是完成的代码。是否有人使用Alamofire来面对这个问题？

Is the a new error in Alamofire 5? as this wasn't running into bugs last time. Below are the code which are done. Anyone who used Alamofire facing this?

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)
    }
  }
}

推荐答案

您必须提取结果值，如下所示，

You have to extract the result value as below,

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)
        }
    }
}
