如何使用PredefinedAcl函数将ACL设置为publicRead？

if res, err := service.Objects.Insert(*bucketName, object).Media(file).Do(); err == nil {
     fmt.Printf("Created object %v at location %v

", res.Name, res.SelfLink)
} else {
     fatalf(service, "Objects.Insert failed: %v", err)
}

I want to modify this code to set the ACL to publicRead, I have noticed there is a function in the API func (*ObjectsInsertCall) PredefinedAcl but I can't find how to use it.

Going by what i found in the docs, it looks like this would do it...

if res, err := service.Objects.Insert(*bucketName, object).Media(file).PredefinedAcl("publicRead").Do(); err == nil {
    fmt.Printf("Created object %v at location %v

", res.Name, res.SelfLink)
} else {
    fatalf(service, "Objects.Insert failed: %v", err)
}

(Inserted it right before the Do() call.) HTH, YMMV, etc.
