我正在尝试通过Google App Engine Go
1.11标准环境上运行的应用程序通过API访问google电子表格。不幸的是，应用程序无法读取此电子表格。

我在Spreadsheets.Values.Get通话中遇到下一个错误：

googleapi: Error 403: Request had insufficient authentication scopes.,forbidden

样例代码

// Sample app showing issue with GAE -> google spreadsheets
package main

import (
    "context"
    "fmt"
    "log"
    "net/http"
    "os"

    "cloud.google.com/go/compute/metadata"
    "golang.org/x/oauth2/google"
    "google.golang.org/api/sheets/v4"
)

func main() {
    http.HandleFunc("/",indexHandler)

    // [START setting_port]
    port := os.Getenv("PORT")
    if port == "" {
        port = "8080"
        log.Printf("Defaulting to port %s\n",port)
    }

    // let's check app engine instance scopes
    scopes,_ := metadata.Get("instance/service-accounts/default/scopes")
    log.Printf("[DEBUG] metadata scopes: %s.\n",scopes)

    log.Printf("Listening on port %s",port)
    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s",port),nil))
    // [END setting_port]
}

// indexHandler responds to requests with our greeting.
func indexHandler(w http.ResponseWriter,r *http.Request) {
    ctx := context.Background()
    client,_ := google.DefaultClient(ctx,"https://www.googleapis.com/auth/spreadsheets.readonly")
    srv,err := sheets.New(client)

    // Prints the names and majors of students in a sample spreadsheet:
    // https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
    spreadsheetId := "1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms"
    readRange := "Class Data!A2:E"
    resp,err := srv.Spreadsheets.Values.Get(spreadsheetId,readRange).Do()
    if err != nil {
        log.Fatalf("Unable to retrieve data from sheet: %v\n",err)
    }

    if len(resp.Values) == 0 {
        fmt.Fprintf(w,"No data found.\n")
    } else {
        fmt.Fprintf(w,"Name,Major:\n")
        for _,row := range resp.Values {
            // Print columns A and E,which correspond to indices 0 and 4.
            fmt.Fprintf(w,"%s,%s\n",row[0],row[4])
        }
    }

}

重现步骤：

1）部署应用程序：gcloud app deploy
2）在浏览器中打开（您将获得502）：gcloud app browse
3）检查日志：gcloud app logs read

有人可以帮忙了解如何解决它吗？

示例项目：https：//github.com/vistrcm/gae-spreadsheet-
issue

我想在Google App
Engine上创建一个RESTful应用。我想提供XML和JSON服务。我已经对Restlet，Resteasy和Jersey进行了简短的实验。除了Restlet中的一些简单示例之外，我在其中的任何方面都没有取得太大的成功。

您能否分享使用Java在Google App Engine上创建Restful Web应用程序的经验，或者对上述GAE工具包提供任何见解？

谢谢！

编辑（2009-07-25）：

我决定暂时使用Restlet。到目前为止，它似乎可以正常工作。请发布您可能有的其他见解/意见。您遇到了什么问题？您是否已在GAE /
J上成功使用Jersey / Restlet / Resteasy？如果是这样，我们想听听！
