Overview ¶
Package fetch offers abstractions to fetch a file with the same method, regardless of a location (filesystem, HTTP...).
Example ¶
package main
import (
"fmt"
"net/http"
"go.thethings.network/lorawan-stack/v3/pkg/fetch"
)
func main() {
fetcher, err := fetch.FromHTTP(http.DefaultClient, "http://webserver.thethings.network/repository")
if err != nil {
panic(err)
}
content, err := fetcher.File("README.md")
if err != nil {
panic(err)
}
fmt.Println("Content of http://webserver.thethings.network/repository/README.md:")
fmt.Println(string(content))
}

Types ¶
type Interface ¶
Interface is an abstraction for file retrieval.
func FromBucket ¶
FromBucket returns an interface that fetches files from the given blob bucket.
func FromFilesystem ¶
FromFilesystem returns an interface that fetches files from the local filesystem.
func NewMemFetcher ¶
NewMemFetcher initializes a new memory fetcher.
Example ¶
package main
import (
"fmt"
"go.thethings.network/lorawan-stack/v3/pkg/fetch"
)
func main() {
fetcher := fetch.NewMemFetcher(map[string][]byte{
"file.txt": []byte("content"),
"dir/file.txt": []byte("content"),
})
content, err := fetcher.File("dir/file.txt")
if err != nil {
panic(err)
}
fmt.Println("Content of myFile.yml")
fmt.Println(string(content))
}
