Swift 4从Google Places API获取多个位置

问题描述 投票:1回答:1

我无法从Google Places API获取多个位置。问题是......如果我只获取一个像Bars这样的引脚类型,那么没问题。但是,如果我试图获得餐馆,酒吧,赌场...倍数类型,它给我唯一的第一名,在我们的情况下餐馆。

我尝试使用Postman与下面的链接提出相同的请求...但是例如

  • 餐厅1030行JSON
  • 政治83行
  • 试图获得餐馆+政治= 965行的JSON。

我使用此代码来获取我想要的地方:

func fetchPlacesNearCoordinate(_ coordinate: CLLocationCoordinate2D, radius: Double, types:[String], completion: @escaping PlacesCompletion) -> Void {

    var urlString = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=\(coordinate.latitude),\(coordinate.longitude)&radius=\(50000)&rankby=prominence&sensor=true&key=\(googleApiKey)"
    let typesString = types.count > 0 ? types.joined(separator: "|") : "food"
    urlString += "&types=\(typesString)"
    urlString = urlString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) ?? urlString

    guard let url = URL(string: urlString) else { completion([]); return }

    if let task = placesTask, task.taskIdentifier > 0 && task.state == .running {
        task.cancel()
    }

    DispatchQueue.main.async {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
    }

    placesTask = session.dataTask(with: url) { data, response, error in

        if data != nil{
            for el in data!{
                //print(el)
            }
        }
        var placesArray: [PlaceContent] = []
        defer {
            DispatchQueue.main.async {
                UIApplication.shared.isNetworkActivityIndicatorVisible = false
                completion(placesArray)
            }
        }

        guard let data = data else { return }

        do{
            let decode = try JSONDecoder().decode(GooglePlacesAnswer.self, from: data)
            placesArray = (decode.results?.map{ $0.toPlaceContent() }) ?? []
        } catch let value{
            print(value.localizedDescription)
        }
    }
    placesTask?.resume()
}

您无法获得官方文档中所述的多种类型的地点。您必须提出多个请求并合并结果。

https://developers.google.com/maps/documentation/javascript/places

type - 将结果限制为与指定类型匹配的位置。只能指定一种类型(如果提供了多种类型,则忽略第一个条目后面的所有类型)。见list of supported types
