所以我用莫亚创建了一个API请求来openweatherAPI，现在Postman上的返回似乎没问题，但是X-code上的API调用返回401：API密钥无效
我试过很多方法来找出问题所在，但似乎找不到答案。

import Foundation
import Moya
import UIKit

enum WeatherAPI {

    case showCurrentWeather(cityName: String)
    case showForcasedWeather(cityName: String)
}

extension WeatherAPI: TargetType {

    var task: Task {
        switch self {
        case .showCurrentWeather(cityName: let cityName):
            let params = ["q":cityName , "APPID": Constants.WEATHER_API_KEY]
            return .requestParameters(parameters: params, encoding: JSONEncoding.default)
        case .showForcasedWeather(cityName: let cityName):
             let params = ["q":cityName , "APPID": Constants.WEATHER_API_KEY]
            return .requestParameters(parameters: params, encoding: JSONEncoding.default)
        }
    }

    var baseURL: URL {
        return URL(string: "https://api.openweathermap.org/data/2.5")!
    }

    var path: String {
        switch self {
        case .showCurrentWeather:
            return "/weather"
        case .showForcasedWeather:
            return "/forecast"
        }
    }

    var method: Moya.Method {
        switch self {
        case .showCurrentWeather:
            return .get
        case .showForcasedWeather:
            return .get
        }}

    var sampleData: Data {
        return Data()
    }

    var headers: [String : String]? {
        switch self {
        case .showCurrentWeather:
            return ["Content-type":"application/json"]
        case .showForcasedWeather:
            return ["Content-type":"application/json"]
        }
    }
}

在Postman和浏览器上运行良好。
