Google Road Api SnapToRoad golang [英] Google Road Api SnapToRoad golang

问题描述

我试图执行谷歌的 snaptoroad api。但我没有得到任何输出。我正在使用golang来实现。我的代码如下：

I was trying to implement google's snaptoroad api. But I am not getting any output. I am using golang for the implementation. My Code is as follows:

mapClient, err := maps.NewClient(maps.WithAPIKey(GoogleApiServerKey))
if err != nil{
    log.Println(err)
}

//Input
latlng := maps.LatLng{}
path := []maps.LatLng{}
latlng.Lat = 9.7162348
latlng.Lng = 76.6702793
path = append(path, latlng)
latlng.Lat = 9.7162400
latlng.Lng = 76.715195
path = append(path, latlng)
latlng.Lat = 9.7162410
latlng.Lng = 76.7759261
path = append(path, latlng)

inputRequest := &maps.SnapToRoadRequest{
    Path: path,
}

outputResponse, err := mapClient.SnapToRoad(context.Background(), inputRequest)

fmt.Println(outputResponse)
pretty.Println(outputResponse)

此代码产生的输出是

The Output this code produces are

&{[]}
&maps.SnapToRoadResponse{}

返回空白输出。任何人都请指出我在这里犯的错误？提前致谢。

Blank output is returned. Anyone please point out the mistake I made here? Thanks in advance.

推荐答案

您的代码很好，但看起来您的API密钥未被激活。
请访问 googleAPI信息中心
以启用它。

Your code is fine, but It seems that your API Key is not activated. Please visit googleAPI dashboard to enable it.

您可以随时查看它的运作情况：
https://roads.googleapis.com/v1/snapToRoads?path=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796&key=YOUR_API_KEY

You can always check it working: https://roads.googleapis.com/v1/snapToRoads?path=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796&key=YOUR_API_KEY

输出结果为：

the output would be:

{
  "snappedPoints": [
    {
      "location": {
        "latitude": 60.170877918672588,
        "longitude": 24.942699821922421
      },
      "originalIndex": 0,
      "placeId": "ChIJNX9BrM0LkkYRIM-cQg265e8"
    },
    {
      "location": {
        "latitude": 60.170876898776406,
        "longitude": 24.942699912064775
      },
      "originalIndex": 1,
      "placeId": "ChIJNX9BrM0LkkYRIM-cQg265e8"
    },
    {
      "location": {
        "latitude": 60.170874902634374,
        "longitude": 24.942700088491474
      },
      "originalIndex": 2,
      "placeId": "ChIJNX9BrM0LkkYRIM-cQg265e8"
    }
  ]
}
