Question

我已经使用Alamofire定义了要传递给RapidAPI的参数，但是出现错误。

我遵循了他们在API文档中所说的所有内容。如果我将完整的URL放入字符串中，则可以正常工作，但是当我将其作为参数传递时，

import UIKit
import Alamofire
import SwiftyJSON

class ViewController: UIViewController {

    let CURRENT_BR_LEAGUE_URL = "https://api-football-v1.p.rapidapi.com/v2/leagues/country/"

    override func viewDidLoad() {
        super.viewDidLoad()

        let params = ["country_name" : "england", "season" : "2018"]

        getLeague(url: CURRENT_BR_LEAGUE_URL, parameters: params)
    }

    func getHeaders() -> [String : String] {
        let headers = [
            "X-RapidAPI-Host": "api-football-v1.p.rapidapi.com",
            "X-RapidAPI-Key": "xxxxxxxxxxxxxxxxxxx"
        ]
        return headers
    }

    func getLeague (url : String, parameters : [String : String]) {
        Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding(destination: .queryString), headers: getHeaders()).responseJSON {
            response in
            if response.result.isSuccess {

                let leagueJSON : JSON = JSON(response.result.value!)
                print(leagueJSON)
                print()
            }
            else {

            }

        }
    }


}

它引发“错误的国家”错误。如果我使用完整网址 let CURRENT_BR_LEAGUE_URL = "https://api-football-v1.p.rapidapi.com/v2/leagues/country/england/2018"正常。

如果我使用"https://api-football-v1.p.rapidapi.com/v2/leagues/country/" 并设置参数

let params = ["country_name" : "england", "season" : "2018"]

它不起作用

在您的代码中，您正在获取请求。因此，您必须将参数绑定与基本URL一起传递。请尝试以下代码，希望它对您有用。

class ViewController: UIViewController {

    let CURRENT_BR_LEAGUE_URL = "https://api-football-v1.p.rapidapi.com/v2/leagues/country/%@/%@"

    override func viewDidLoad() {
        super.viewDidLoad()

        let params = ["country_name" : "england", "season" : "2018"]

        let urlString =  String(format: CURRENT_BR_LEAGUE_URL, params["country_name"],params["season"])

        getLeague(url: urlString, parameters: nil)
    }

    func getHeaders() -> [String : String] {
        let headers = [
            "X-RapidAPI-Host": "api-football-v1.p.rapidapi.com",
            "X-RapidAPI-Key": "xxxxxxxxxxxxxxxxxxx"
        ]
        return headers
    }

    func getLeague (url : String, parameters : [String : String]?) {
        Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding(destination: .queryString), headers: getHeaders()).responseJSON {
            response in
            if response.result.isSuccess {

                let leagueJSON : JSON = JSON(response.result.value!)
                print(leagueJSON)
                print()
            }
            else {

            }

        }
    }
}

当我现在查看API-Football的RapidApi文档时，不需要参数。您只需要从不同的部分构造URL，然后发出GET请求即可。

class ViewController: UIViewController {

    let MAIN_URL = "https://api-football-v1.p.rapidapi.com/v2/leagues/country/"

    override func viewDidLoad() {
        super.viewDidLoad()

        getLeague(for: "england", year: 2018)
    }

    func getHeaders() -> [String : String] {
        let headers = [
            "X-RapidAPI-Host": "api-football-v1.p.rapidapi.com",
            "X-RapidAPI-Key": "xxxxxxxxxxxxxxxxxxx"
        ]
        return headers
    }

    func getLeague (for country : String, year: Int) {

        let url = MAIN_URL + country + "/\(year)/"

        Alamofire.request(url, method: .get, parameters: nil, encoding: URLEncoding.default, headers: getHeaders()).responseJSON {
            response in
            if response.result.isSuccess {

                let leagueJSON : JSON = JSON(response.result.value!)
                print(leagueJSON)
                print()
            }
            else {

            }
        }
    }
}

无法使用Alamofire将参数传递到网址
