mod_http_oauth2: Revert role selector, going to try something else Back out f2c7bb3af600 Allowing only a single role to be encoded into the grant takes away the possibility of having multiple roles in the grant, one of which is selected when issuing an access token. It also takes away the ability to have zero roles granted, which could be useful e.g. when you only need OIDC scopes.

labels: 'Stage-Alpha'

Introduction
============

This module implements [XEP-0363], versions 0.2 and 0.3, which let
clients upload files over HTTP.

Configuration
=============

mod\_http\_upload relies on Prosodys HTTP server and mod\_http for
serving HTTP requests. See [Prosodys HTTP server documentation][doc:http]
for information about how to configure ports, HTTP Host names etc.

The module can be added as a new Component definition:

``` {.lua}
Component "upload.example.org" "http_upload"
```

It should **not** be added to modules_enabled.

## Discoverability

Prosody makes subdomains of your VirtualHosts easily discoverable by
clients. To make the component discoverable by other hosts where the
component is **not a subdomain** of the VirtualHost, you can use
[`disco_items`][doc:modules:mod_disco#configuration].

``` {.lua}
VirtualHost "foo.example.org"
disco_items = {
    { "upload.example.com" },
}
```

## Access

You may want to give upload access to additional entities such as components
by using the `http_upload_access` config option.

``` {.lua}
http_upload_access = {"gateway.example.com"};
```

Limits
------

### Max size

A maximum file size can be set by:

``` {.lua}
http_upload_file_size_limit = 123 -- bytes
```

Default is 1MB (1024\*1024).

This can not be set over the value of `http_max_content_size` (default 10M).
Consider [mod_http_upload_external] instead of attempting to increase
this limit.

### Max age

Files can be set to be deleted after some time:

``` lua
http_upload_expire_after = 60 * 60 * 24 * 7 -- a week in seconds
```

Expired files are deleted when a new upload slot is requested,

A command exists to invoke expiry:

```
prosodyctl mod_http_upload expire [list of users or hosts]
```

### User quota

A total maximum size of all uploaded files per user can be set by:

``` lua
http_upload_quota = 1234 -- bytes
```

A request for a slot that would take an user over quota is denied.

Path
----

By default, uploaded files are put in a sub-directory of the default
Prosody storage path (usually `/var/lib/prosody`). This can be changed:

``` {.lua}
http_upload_path = "/path/to/uploaded/files"
```

Compatibility
=============

Works with Prosody 0.11.x and later.

In Prosody 0.12 and later, consider switching to [mod_http_file_share](https://prosody.im/doc/modules/mod_http_file_share)
which is distributed with Prosody. You can migrate existing files using
[mod_migrate_http_upload](https://modules.prosody.im/mod_migrate_http_upload.html).
