如何与golang一起使用Google Analytics Data API v1

Question

中没有golang演示代码可以使用Google Analytics Data API v1https://developers.google.com/analytics/devguides/reporting/data/v1/quickstart-client-libraries

当我编写golang代码以使用Analytics Data API v1时，会出现以下错误：

C:Usersqiuskillgosrcgoogle_api_test>go run main.go

下面是我的源代码，我用*******替换了我的属性ID:

package main
import (
"context"
"fmt"
data "google.golang.org/genproto/googleapis/analytics/data/v1beta"
"google.golang.org/grpc"
)
func main() {
cc := &grpc.ClientConn{}
// fmt.Println(cc)
client := data.NewBetaAnalyticsDataClient(cc)
fmt.Println(client)
ctx := context.Background()
runReportRequest := &data.RunReportRequest{
Property: "properties/*******",
DateRanges: []*data.DateRange{
{StartDate: "2022-01-10", EndDate: "2022-01-10"},
},
Dimensions: []*data.Dimension{
{Name: "city"},
},
Metrics: []*data.Metric{
{Name: "activeUsers"},
},
}
// fmt.Println(runReportRequest)
_, err := client.RunReport(ctx, runReportRequest)
if err != nil {
panic(err)
} else {
// cnt := response.RowCount
// println(string(cnt))
}
}

任何人都能知道发生错误的原因吗？或者任何人都可以编写golang演示来使用Google Analytics Data API v1，等待您的答案，非常感谢！！！

Answer 1

这是一个工作示例：

package main
import (
"context"
"fmt"
"github.com/labstack/echo/v4"
ga "google.golang.org/api/analyticsdata/v1beta"
"google.golang.org/api/option"
"net/http"
)
func main() {
ctx := context.Background()
client, err := ga.NewService(ctx, option.WithCredentialsFile("client.json"))
if err != nil {
panic(err)
}
runReportRequest := &ga.RunReportRequest{
DateRanges: []*ga.DateRange{
{
StartDate: "2022-04-19",
EndDate: "today"
},
},
//Dimensions: []*data.Dimension{
//    {
//        Name: "city"
//    },
//},
Metrics: []*ga.Metric{
{
Name: "activeUsers"
},
},
}
e := echo.New()
e.GET("/", func(c echo.Context) error {
r, _ := client.Properties.RunReport("properties/xxxxxxx", runReportRequest).Do()
fmt.Println(r)
return c.JSON(http.StatusOK, r.Rows)
})
e.Logger.Fatal(e.Start(":1323"))
}
