File API

The file API enables web clients to read and write files at arbitrary VFS locations.

  • API URL: /api/file

  • Methods:

    • GET – read file

    • POST – write file

  • Parameters:

    • path – the full path to the file

    • content – the new file content on POST

  • Output:

    • HTTP status: 200 (OK) or 400 (Error)

    • HTTP body: file content on GET or error message

On writing, missing directories along the path will be created automatically.

Usage Example

The API can be accessed easily in the web frontend with the jQuery AJAX methods:

// Write object JSON encoded into file:
var json = JSON.stringify(object);
$.post("/api/file", { "path": "/sd/mystore/file1", "content": json })
  .done(function() {
    confirmdialog('Saved', '<p>File has been saved.</p>', ["OK"], 2);
  .fail(function(jqXHR) {
    confirmdialog('Save failed', jqXHR.responseText, ["OK"]);

// Read JSON encoded object from file:
$.get("/api/file", { "path": "/sd/mystore/file1" })
  .done(function(responseText) {
    var object = JSON.parse(responseText);
    // … process object …
  .fail(function(jqXHR) {
    confirmdialog('Load failed', jqXHR.responseText, ["OK"]);

External Access

From external clients, the API can be used by either registering a session cookie or by supplying the apikey parameter (as explained in the general authorization overview).

Read example:

curl ""

Write example:

curl "" -d 'apikey=password' \
  -d 'path=/sd/mystore/file1' --data-urlencode 'content@localfile'
