_This is a different approach to #20267, I took the liberty of adapting some parts, see below_ ## Context In some cases, a weebhook endpoint requires some kind of authentication. The usual way is by sending a static `Authorization` header, with a given token. For instance: - Matrix expects a `Bearer <token>` (already implemented, by storing the header cleartext in the metadata - which is buggy on retry #19872) - TeamCity #18667 - Gitea instances #20267 - SourceHut https://man.sr.ht/graphql.md#authentication-strategies (this is my actual personal need :) ## Proposed solution Add a dedicated encrypt column to the webhook table (instead of storing it as meta as proposed in #20267), so that it gets available for all present and future hook types (especially the custom ones #19307). This would also solve the buggy matrix retry #19872. As a first step, I would recommend focusing on the backend logic and improve the frontend at a later stage. For now the UI is a simple `Authorization` field (which could be later customized with `Bearer` and `Basic` switches): ![2022-08-23-142911](https://user-images.githubusercontent.com/3864879/186162483-5b721504-eef5-4932-812e-eb96a68494cc.png) The header name is hard-coded, since I couldn't fine any usecase justifying otherwise. ## Questions - What do you think of this approach? @justusbunsi @Gusted @silverwind - ~~How are the migrations generated? Do I have to manually create a new file, or is there a command for that?~~ - ~~I started adding it to the API: should I complete it or should I drop it? (I don't know how much the API is actually used)~~ ## Done as well: - add a migration for the existing matrix webhooks and remove the `Authorization` logic there _Closes #19872_ Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: Gusted <williamzijl7@hotmail.com> Co-authored-by: delvh <dev.lh@web.de>

# Webhooks
|
|
|
|
Gitea supports webhooks for repository events. This can be configured in the settings
|
|
page `/:username/:reponame/settings/hooks` by a repository admin. Webhooks can also be configured on a per-organization and whole system basis.
|
|
All event pushes are POST requests. The methods currently supported are:
|
|
|
|
- Gitea (can also be a GET request)
|
|
- Gogs
|
|
- Slack
|
|
- Discord
|
|
- Dingtalk
|
|
- Telegram
|
|
- Microsoft Teams
|
|
- Feishu
|
|
- Wechatwork
|
|
- Packagist
|
|
|
|
### Event information
|
|
|
|
**WARNING**: The `secret` field in the payload is deprecated as of Gitea 1.13.0 and will be removed in 1.14.0: https://github.com/go-gitea/gitea/issues/11755
|
|
|
|
The following is an example of event information that will be sent by Gitea to
|
|
a Payload URL:
|
|
|
|
```
|
|
X-GitHub-Delivery: f6266f16-1bf3-46a5-9ea4-602e06ead473
|
|
X-GitHub-Event: push
|
|
X-Gogs-Delivery: f6266f16-1bf3-46a5-9ea4-602e06ead473
|
|
X-Gogs-Event: push
|
|
X-Gitea-Delivery: f6266f16-1bf3-46a5-9ea4-602e06ead473
|

### Example
|
|
|
|
This is an example of how to use webhooks to run a php script upon push requests to the repository.
|
|
In your repository Settings, under Webhooks, Setup a Gitea webhook as follows:
|
|
|
|
- Target URL: http://mydomain.com/webhook.php
|
|
- HTTP Method: POST
|
|
- POST Content Type: application/json
|
|
- Secret: 123
|
|
- Trigger On: Push Events
|
|
- Active: Checked
|
|
|
|
Now on your server create the php file webhook.php
|
|
|
|
```
|
|
<?php
|
|
|
|
$secret_key = '123';
|
|
|
|
// check for POST request
|
|
if ($_SERVER['REQUEST_METHOD'] != 'POST') {
|
|
error_log('FAILED - not POST - '. $_SERVER['REQUEST_METHOD']);
|
|
exit();
|
|
}
|
|
|
|
// get content type
|
|
$content_type = isset($_SERVER['CONTENT_TYPE']) ? strtolower(trim($_SERVER['CONTENT_TYPE'])) : '';
|
|
|
|
if ($content_type != 'application/json') {
|
|
error_log('FAILED - not application/json - '. $content_type);
|
|
exit();
|
|
}
|
|
|
|
// get payload
|
|
$payload = trim(file_get_contents("php://input"));
|
|
|
|
if (empty($payload)) {
|
|
error_log('FAILED - no payload');
|
|
exit();
|
|
}
|
|
|
|
// get header signature
|
|
$header_signature = isset($_SERVER['HTTP_X_GITEA_SIGNATURE']) ? $_SERVER['HTTP_X_GITEA_SIGNATURE'] : '';
|
|
|
|
if (empty($header_signature)) {
|
|
error_log('FAILED - header signature missing');
|
|
exit();
|
|
}
|
|
|
|
// calculate payload signature
|
|
$payload_signature = hash_hmac('sha256', $payload, $secret_key, false);
|
|
|
|
// check payload signature against header signature
|
|
if ($header_signature !== $payload_signature) {
|
|
error_log('FAILED - payload signature');
|
|
exit();
|
|
}
|
|
|
|
// convert json to array
|
|
$decoded = json_decode($payload, true);
|
|
|
|
// check for json decode errors
|
|
if (json_last_error() !== JSON_ERROR_NONE) {
|
|
error_log('FAILED - json decode - '. json_last_error());
|
|
exit();
|
|
}
|
|
|
|
// success, do something
|
|
```
|
|
|
|
There is a Test Delivery button in the webhook settings that allows to test the configuration as well as a list of the most Recent Deliveries.
|
|
|
|
### Authorization header
|
|
|
|
**With 1.19**, Gitea hooks can be configured to send an [authorization header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization) to the webhook target.
