Functions ¶
func BlobKeyForFile ¶
BlobKeyForFile returns a BlobKey for a Google Storage file. The filename should be of the form "/gs/bucket_name/object_name".
func DeleteMulti ¶
DeleteMulti deletes multiple blobs.
func ParseUpload ¶
ParseUpload parses the synthetic POST request that your app gets from App Engine after a user's successful upload of blobs. Given the request, ParseUpload returns a map of the blobs received (keyed by HTML form element name) and other non-blob POST parameters.
func Send ¶
func Send(response http.ResponseWriter, blobKey appengine.BlobKey)
Send sets the headers on response to instruct App Engine to send a blob as the response body. This is more efficient than reading and writing it out manually and isn't subject to normal response size limits.
Types ¶
type BlobInfo ¶
type BlobInfo struct {
BlobKey appengine.BlobKey
ContentType string `datastore:"content_type"`
CreationTime time.Time `datastore:"creation"`
Filename string `datastore:"filename"`
Size int64 `datastore:"size"`
MD5 string `datastore:"md5_hash"`
// ObjectName is the Google Cloud Storage name for this blob.
ObjectName string `datastore:"gs_object_name"`
}
BlobInfo is the blob metadata that is stored in the datastore. Filename may be empty.
type UploadURLOptions ¶
type UploadURLOptions struct {
MaxUploadBytes int64 // optional
MaxUploadBytesPerBlob int64 // optional
// StorageBucket specifies the Google Cloud Storage bucket in which
// to store the blob.
// This is required if you use Cloud Storage instead of Blobstore.
// Your application must have permission to write to the bucket.
// You may optionally specify a bucket name and path in the format
// "bucket_name/path", in which case the included path will be the
// prefix of the uploaded object's name.
StorageBucket string
}
UploadURLOptions are the options to create an upload URL.
