【问题描述】：

处理我的第一个 Alamofire 请求和更新到 Alamofire 4 的代码。无法正确更新此 Alamofire.request .responseJSON。我在看 Migration documentation: 但不够聪明。有什么建议吗？

    let APIKey = "myAPIkey"

func retrieveCurrentWeatherAtLat(lat: CLLocationDegrees, lon: CLLocationDegrees,
                                 block: (_ weatherCondition: WeatherCondition) -> Void) 
    let url = "http://api.openweathermap.org/data/2.5/weather?APPID=\(APIKey)"
    let params = ["lat": lat, "lon": lon]

    //  Send the request
    Alamofire.request(url, method: .get, parameters: params)
        .responseJSON  request, response, result in
            switch result 
            case .Success(let json):
                let json = JSON(json)
                block(weatherCondition: self.createWeatherConditionFronJson(json))
            case .Failure(_, let error):
                print("Error: \(error)")
            
    

【参考方案1】：

或许能帮到你

    Alamofire.request(url, method: .get, parameters: params, encoding: JSONEncoding.default).responseJSON  (response) in

        switch response.result 
       case .Success(let json):
            let json = JSON(json)
            block(weatherCondition: self.createWeatherConditionFronJson(json))
        case .Failure(_, let error):
            print("Error: \(error)")

伟大的看起来更好。如果收到感谢@fidetro，我会去测试 :)

【参考方案2】：

let APIKey = "YourApiKeyComesHere"

//  Sending the request to Open Weather
func retrieveCurrentWeatherAtLat(lat: CLLocationDegrees, lon: CLLocationDegrees,
                                 block: @escaping (_ weatherCondition: WeatherCondition) -> Void) 
    let url = "https://api.openweathermap.org/data/2.5/weather?APPID=\(APIKey)"
    let params = ["lat": lat, "lon": lon]
    print("Sending request... \(url)")
    let request = Alamofire.request(url, method: .get, parameters: params, encoding: URLEncoding(destination: .queryString)).responseJSON  (response) in
        print("Got response from server: \(response)")
        switch response.result 
        case .success(let json):
            let json = JSON(json)
            block(self.createWeatherConditionFronJson(json: json))
            print("Success: \(json)") //test
        case .failure(let error):
            print("Error: \(error)")
        
    
    request.resume()

【讨论】：

3 个小改动：.succes / .failure / block：@escaping

经过测试，现在它以纬度和经度为参数获取请求。
