无效 url google 地图方向 api 使用 swift 和 alamofire 的路径点

Question

我正在尝试使用 google 地图方向 API 在 google 地图上绘制点列表的方向，我正在使用 alamofire 进行网络请求，当我尝试使用我的浏览器获取响应 JSON 数据时，它工作正常并且它 returns 所需的数据，但是当我使用 alamofire 请求时，我收到此响应错误：

URL is not valid

这是我的代码：

        let headers: HTTPHeaders = [ "Accept": "application/json", "Content-Type": "application/json" ]

        let url = "https://maps.googleapis.com/maps/api/directions/json?origin= 33.85735529390786,35.48763965724007&destination=33.86317291423991,35.49212425947189&mode=driving&waypoints=|21.4276001,39.2765001|21.4025001,39.2744001|21.7728001,39.1931001|21.7081001,39.1044001&key=myKey"

          Alamofire.request(url, method: .post, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in

                    print(response.request as Any)  // original URL request
                    print(response.response as Any) // HTTP URL response
                    print(response.data as Any)     // server data
                    print(response.result as Any)   // result of response serialization
                    do{
                        let json = try JSON(data: response.data!)
                        let routes = json["routes"].arrayValue

                        // print route using Polyline
                        for route in routes{
                            let routeOverviewPolyline = route["overview_polyline"].dictionary
                            let points = routeOverviewPolyline?["points"]?.stringValue
                            let path = GMSPath.init(fromEncodedPath: points!)
                            let polyline = GMSPolyline.init(path: path)
                            polyline.strokeWidth = 4
                            polyline.strokeColor = UIColor.blue
                            polyline.map = self.mapView
                        }
                    }catch let error {
   print(error.localizedDescription)
                    }


                }

提前致谢。

您需要添加addingPercentEncoding。

  var url = "https://maps.googleapis.com/maps/api/directions/json?origin= 33.85735529390786,35.48763965724007&destination=33.86317291423991,35.49212425947189&mode=driving&|21.4276001,39.2765001|21.4025001,39.2744001|21.7728001,39.1931001|21.7081001,39.1044001&key=myKey"

  url = url.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
