Thanks for the snippet. I made some adjustments to make it work with the json key file you can download from Google cloud console.
package main
import (
"fmt"
"io/ioutil"
"log"
"time"
"cloud.google.com/go/storage"
"golang.org/x/oauth2/google"
)
func main() {
sakeyFile := "/home/tamal/Downloads/xyz.json"
saKey, err := ioutil.ReadFile(sakeyFile)
if err != nil {
log.Fatalln(err)
}
cfg, err := google.JWTConfigFromJSON(saKey)
if err != nil {
log.Fatalln(err)
}
bucket := "go-cloud"
filename := "mypic3.json"
method := "GET"
expires := time.Now().Add(time.Second * 60)
url, err := storage.SignedURL(bucket, filename, &storage.SignedURLOptions{
GoogleAccessID: cfg.Email,
PrivateKey: cfg.PrivateKey,
Method: method,
Expires: expires,
})
if err != nil {
fmt.Println("Error " + err.Error())
}
fmt.Println(url)
}
Great example, thanks!
how do we get an Unsigned URL? so dumb I can't find that
once you get the signed URL, how can I use curl command to upload a file? Can someone please help with an example?
Indeed, it would look something like this:
curl -X PUT --progress-bar -H 'Content-Type: application/mxf' --upload-file 'path_to_file.txt' 'Signed URL'
where Content-Type: application/mxf
will vary based on the type of file you're uploading, and path_to_file.txt
and Signed URL
need to be replaced with your actual values.
Thanks
