ios - Swift 3中的Google Maps API指南

Question

当我开始使用Swift 3时，在使用Google Maps API指南构建路线时遇到了问题。

我的路线有几个航点，在Swift 3中，URL:

https://maps.googleapis.com/maps/api/directions/json?origin=48.4843822562792,35.0635632500052&destination=48.4893899423081,35.0640017911792&waypoints=48.4833428800255,35.0710221379995|48.4887622031403,35.0573639944196&key=AIzaSyAWpBT3uxovKLqdWIiwa29a4AcgtspAA1k

由于“|”而无效。有什么建议么？

对于那些想使用路线googlemaps api的人，您必须在参数数组中发送航点。因此，管道不再引起问题。

    var wayPointsString = "optimize:true"
    if waypointsForRequest.count > 0 {
        for location in waypointsForRequest {
            wayPointsString = "\(wayPointsString)|\(location.coordinate.latitude),\(location.coordinate.longitude)"
        }
    }
    let parameters : [String : String] = ["key" : self.directionsApikey, "sensor" : "false", "mode" : "driving", "alternatives" : "true", "origin" : "\(origin.coordinate.latitude),\(origin.coordinate.longitude)", "destination" : "\(destination.coordinate.latitude),\(destination.coordinate.longitude)", "waypoints" : wayPointsString]
    let url = URL(string: "https://maps.googleapis.com/maps/api/directions/json?")

    Alamofire.request(url!, method:.get, parameters: parameters)
        .validate(contentType: ["application/json"])
        .responseJSON { response in
            if response.value != nil {
                let json = JSON(response.value!)

            }
    }
