How to use Directions response in the Go client for Google Maps Services?

问题

使用googlemaps.github.io/maps在Go中获取方向时，响应是一个maps.Route数组。是否有办法将此响应转换为JavaScript的google.maps.DirectionsRenderer()可以读取的内容？这样做的目的是通过Go服务器获取方向并将该数据分发到多个平台。欢迎对如何将此数据转换为可视化地图的任何建议。

Go代码：

  1. package main
  3. import (
  4.     "log"
  6.     "googlemaps.github.io/maps"
  7.     "github.com/kr/pretty"
  8.     "golang.org/x/net/context"
  9. )
  11. func checkForError(err error) {
  12.     if err != nil{
  13.         log.Fatal(err)
  14.     }
  15. }
  17. func main() {
  18.     c, err := maps.NewClient(maps.WithAPIKey("myapikey"))
  19.     checkForError(err)
  21.     r := &maps.DirectionsRequest{
  22.         Origin:      "Hollywood, FL",
  23.         Destination: "Davie, FL",
  24.     }
  26.     resp, _, err := c.Directions(context.Background(), r)
  27.     checkForError(err)
  29.     // render := 
  31.     pretty.Println(resp)
  32. }

输出：

When getting directions using "googlemaps.github.io/maps" in Go, the response is an array of maps.Route . Is there a way to turn this response into something readable by javascript's google.maps.DirectionsRenderer(); , the purpose of this is to get the directions with a go server and distribute that data into multiple platforms. Any suggestions about how to transform this data into a visual map are welcome.

Go code:

  1. package main
  2. import (
  3. &quot;log&quot;
  4. &quot;googlemaps.github.io/maps&quot;
  5. &quot;github.com/kr/pretty&quot;
  6. &quot;golang.org/x/net/context&quot;
  7. )
  8. func checkForError(err error) {
  9. if err != nil{
  10. log.Fatal(err)
  11. }
  12. }
  13. func main() {
  14. c, err := maps.NewClient(maps.WithAPIKey(&quot;myapikey&quot;))
  15. checkForError(err)
  16. r := &amp;maps.DirectionsRequest{
  17. Origin:      &quot;Hollywood, FL&quot;,
  18. Destination: &quot;Davie, FL&quot;,
  19. }
  20. resp, _, err := c.Directions(context.Background(), r)
  21. checkForError(err)
  22. // render := 
  23. pretty.Println(resp)
  24. }

答案1

得分: 1

那个JSON输出是一个DirectionsResult对象，它通过DirectionsRendererOptions直接传递给你所询问的DirectionsRenderer()构造函数。

如果你想将其转换为Go语言，你可以使用相同的结构体将其转换回来，以供寻找DirectionsResult对象的消费者使用。

英文:

That JSON output is a DirectionsResult object, which is passed in through the DirectionsRendererOptions directly to the DirectionsRenderer() constructor you're asking about.

If you're trying to marshal it in to Go you can use the same structs to marshal it back out for consumers that are looking for a DirectionsResult object.
