S3

S3 filesystems are only accessible via HTTP their configured mountpoint. Use the POST or PUT method with the path to that file to (over-)write a file. The body of the request contains the contents of the file. No particular encoding or Content-Type is required. The file can then be downloaded from the same path.

This filesystem is practical rarely changing data (e.g. VOD) for long term storage.

On this page and in the examples we assume that a S3 storage with the name aws is mounted on /awsfs.

curl http://127.0.0.1:8080/awsfs/path/to/a/file.txt -X PUT -d @somefile.txt

The returned Content-Type is based solely on the file extension. For a list of known mime-types and their extensions see storage.mime_types in the configuration.

Access protection

It is strongly recommended to enable a username/password (HTTP Basic-Auth) protection for any PUT/POST and DELETE operations on /memfs. GET operations are not protected.

By default HTTP Basic-Auth is not enabled.

API

The contents of the S3 filesystem mounted on /awsfs are also accessible via the API in the same way as described above, but with the same protection as the API (see API-Security configuration) for all operations. It is also possible to list all files that are currently in the filesystem.

Create, Update

Example:

echo 'test' > example.txt && \
curl http://127.0.0.1:8080/api/v3/fs/aws/example.txt \
   -d @example.txt \
   -X PUT

import (
    "strings"
    "github.com/datarhei/core-client-go/v16"
)

client, _ := coreclient.New(coreclient.Config{
    Address: "https://127.0.0.1:8080",
})

data := strings.NewReader("test")
err := client.FilesystemAddFile("aws", "/example.txt", data)

The contents for the upload has to be provided as an io.Reader.

After the successful upload the file is available at /awsfs/example.txt and /api/v3/fs/aws/example.txt.

List all files

Listing all currently stored files is done by calling /api/v3/fs/aws. It also accepts the query parameters pattern, sort (name, size, or lastmod) and order (asc or desc). If none of the parameters are given, all files will be listed sorted by their last modification time in ascending order.

With the pattern parameter you can filter the list based on a glob pattern, with the addition of the ** placeholder to include multiple subdirectories, e.g. listing all .ts file in the root directory has the pattern /*.ts, listing all .ts file in the whole filesystem has the pattern /**.ts.

Example:

curl "http://127.0.0.1:8080/api/v3/fs/aws?sort=name&order=asc" \
   -X GET

import (
    "fmt"
    "github.com/datarhei/core-client-go/v16"
)

client, _ := coreclient.New(coreclient.Config{
    Address: "https://127.0.0.1:8080",
})

files, err := client.FilesystemList("aws", "/*.", coreclient.SORT_NAME, coreclient.ORDER_ASC)

for _, file := range files {
    fmt.Printf("%+v\n", file)
}

Description:

List all files on a filesystem

get

Download a file

For downloading a file you have to specify the complete path and filename. The Content-Type will always be application/data.

Example:

curl http://127.0.0.1:8080/api/v3/fs/aws/example.txt \
   -X GET

from core_client import Client

client = Client(base_url="http://127.0.0.1:8080")
client.login()

core_memfs_file = client.v3_fs_get_file(
    name="aws",
    path="example.txt"
)
print(core_memfs_file)

import (
    "github.com/datarhei/core-client-go/v16"
)

client, _ := coreclient.New(coreclient.Config{
    Address: "https://127.0.0.1:8080",
})

data, err := client.FilesystemGetFile("aws", "/example.txt")
defer data.Close()

The returned data is an io.ReadCloser.

Delete

For deleting a file you have to specify the complete path and filename.

Example:

   -X DELETE

import (
