有关详情，请参阅获取公交路线。

公交路线矩阵示例

以下示例计算公交路线矩阵，除了请求路线矩阵的典型字段掩码之外，还会请求公交票价：

curl -X POST -d '{
  "origins": [
    {
      "waypoint": {
        "location": {
          "latLng": {
            "latitude": 37.420761,
            "longitude": -122.081356
          }
        }
      }
    },
    {
      "waypoint": {
        "location": {
          "latLng": {
