# Webhook
|
||
|
||
Gitea 的儲存庫事件支援 web hook。這可以有儲存庫管理員在設定頁 `/:username/:reponame/settings/hooks` 中調整。Webhook 也可以按照組織調整或按照全系統調整。
|
||
所有的事件推送都是 POST 請求。此方法目前被下列服務支援：
|
||
|
||
- Gitea (也可以是 GET 請求)
|
||
- Gogs
|
||
- Slack
|
||
- Discord
|
||
- Dingtalk
|
||
- Telegram
|
||
- Microsoft Teams
|
||
- Feishu
|
||
- Wechatwork
|
||
- Packagist
|
||
|
||
### 事件資訊
|
||
|
||
**警告**： Payload 中的 `secret` 欄位已經在 Gitea 1.13.0 棄用，並且將在 1.14.0 移除： https://github.com/go-gitea/gitea/issues/11755
|
||
|
||
下面是一個將由 Gitea 發送到 Payload URL 的事件資訊的範例：

### 範例
|
||
|
||
此範例示範在發生推送事件時，如何使用 webhook 觸發 php 程式。
|
||
使用下列參數在您的儲存庫設定 Webhook 中建立一個 Gitea webhook：
|
||
|
||
- 目標 URL： http://mydomain.com/webhook.php
|
||
- HTTP 請求方法：POST
|
||
- POST Content Type：application/json
|
||
- Secret：123
|
||
- 觸發條件：推送事件
|
||
- 啟用：勾選
|
||
|
||
現在請到您的伺服器上建立 webhook.php 檔案
|
||
|
||
```
|
||
<?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
|
||
```
|
||
|
||
Webhook 設定中有一個傳送測試資料按鈕，它可讓你測試您的設定並將結果顯示於最近傳送記錄。
