我尝试使用Google Directions API解析估计的行程持续时间和两个航路点之间的距离，我想在Google地图上进行此操作。 这是api
http://maps.googleapis.com/maps/api/directions/json?mode=walking&origin=13.0262523,77.5892838&destination=13.0282523,77.5892838&sensor=false
这是json结果

我搜索了很多方法我找不到任何东西，我想在谷歌地图上打印标签中两个位置之间的持续时间和距离
答案 0 :(得分：0)
以下是解析距离和持续时间的代码
var urlString = String(format:"https://maps.googleapis.com/maps/api/directions/json?origin=%f,%f&destination=%f,%f&alternatives=%@&mode=%@&key=%@",soutLatitude,soutLongitude,destLatitude,destLongitude,"true","driving",google_directions_places_key)
urlString = urlString.addingPercentEncoding( withAllowedCharacters: .urlQueryAllowed)!
let manager=AFHTTPRequestOperationManager()
manager.responseSerializer = AFJSONResponseSerializer(readingOptions: JSONSerialization.ReadingOptions.allowFragments) as AFJSONResponseSerializer
manager.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
manager.responseSerializer.acceptableContentTypes = NSSet(objects:"application/json", "text/html", "text/plain", "text/json", "text/javascript", "audio/wav") as Set<NSObject>
manager.post(urlString, parameters: nil, success: { (operation, response) in
if(response != nil)
{
let parsedData = JSON(response!)
print("parsedData12554 : \(parsedData)")
print("parsed : \(parsedData["status"])")
if(parsedData["status"] == "OK")
{
let routes = parsedData["routes"][0]
print("Routesss260 \(routes)")
let legs = routes["legs"][0]
let distance = legs["distance"]
let duration = legs["duration"]
let disValue = distance["value"].double!
let durValue = duration["value"].double! / 3600.0
print("disValue250 \(disValue)")
print("durValue250 \(durValue)")
if(durValue != 0.0)
{
self.speed = disValue / durValue
}
}
}
}) { (operation, error) in
print("eeee2566\(error)")
}
按照我使用
的相同步骤操作 pod 'SwiftyJSON' , '3.0.0'
pod 'AFNetworking' , '2.5.4'
