Автоматическое повторение неудачных поставок для веб-перехватчика репозитория

Вы можете написать скрипт для обработки неудачных поставок веб-перехватчика репозитория.

О автоматическом повторном развертывании неудачных поставок

В этой статье описывается, как написать скрипт для поиска и повторного выполнения доставки для веб-перехватчика репозитория. Дополнительные сведения о неудачных поставках см. в разделе "Обработка неудачных поставок веб-перехватчика".

В этом примере показано:

  • Скрипт, который будет находить и переэливерить неудачные поставки для веб-перехватчика репозитория
  • Какие учетные данные потребуется скрипту, а также как безопасно хранить учетные данные как секреты GitHub Actions
  • Рабочий процесс GitHub Actions, который может безопасно получить доступ к учетным данным и периодически запускать скрипт

В этом примере используется GitHub Actions, но вы также можете запустить этот скрипт на сервере, который обрабатывает поставки веб-перехватчика. Дополнительные сведения см. в разделе "Альтернативные методы".

Хранение учетных данных для скрипта

Встроенные GITHUB_TOKEN веб-перехватчики не имеют достаточных разрешений. Вместо использования GITHUB_TOKENв этом примере используется personal access token. Кроме того, вместо создания personal access tokenможно создать GitHub App и использовать учетные данные приложения для создания маркера доступа к установке во время рабочего процесса GitHub Actions . Дополнительные сведения см. в разделе «AUTOTITLE».

  1. Создайте personal access token с repo помощью область. Дополнительные сведения см. в разделе «AUTOTITLE».

  2. Сохраните данные personal access token в виде секрета GitHub Actions в репозитории, где требуется запустить рабочий процесс. Дополнительные сведения см. в разделе «AUTOTITLE».

Добавление рабочего процесса, который будет запускать скрипт

В этом разделе показано, как использовать рабочий процесс GitHub Actions для безопасного доступа к учетным данным, хранящимся в предыдущем разделе, задания переменных среды и периодического запуска скрипта для поиска и повторной отправки.

Скопируйте этот рабочий процесс GitHub Actions в файл YAML в каталоге .github/workflows в репозитории, где требуется запустить рабочий процесс. Замените заполнители на шаге Run script , как описано ниже.

YAML
name: Redeliver failed webhook deliveries
on:
  schedule:
    - cron: '20 */6 * * *'
  workflow_dispatch:

This workflow runs every 6 hours or when manually triggered.

permissions:
  contents: read

This workflow will use the built in GITHUB_TOKEN to check out the repository contents. This grants GITHUB_TOKEN permission to do that.

This workflow will run a script that is stored in the repository. This step checks out the repository contents so that the workflow can access the script.

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18.x'

This step sets up Node.js. The script that this workflow will run uses Node.js.

      - name: Install dependencies
        run: npm install octokit

This step installs the octokit library. The script that this workflow will run uses the octokit library.

      - name: Run script

        run: |
          node .github/workflows/scripts/redeliver-failed-deliveries.js

This step sets some environment variables, then runs a script to find and redeliver failed webhook deliveries.

  • Replace YOUR_SECRET_NAME with the name of the secret where you stored your personal access token.
  • Replace YOUR_REPO_OWNER with the owner of the repository where the webhook was created.
  • Replace YOUR_REPO_NAME with the name of the repository where the webhook was created.
  • Replace YOUR_HOOK_ID with the ID of the webhook.
  • Replace YOUR_LAST_REDELIVERY_VARIABLE_NAME with the name that you want to use for a configuration variable that will be stored in the repository where this workflow is stored. The name can be any string that contains only alphanumeric characters and _, and does not start with GITHUB_ or a number. For more information, see "Переменные."
  • Replace YOUR_HOSTNAME with the name of ваш экземпляр GitHub Enterprise Server.

Добавление скрипта

В этом разделе показано, как создать скрипт для поиска и повторного создания неудачных поставок.

Скопируйте этот скрипт в файл, который вызывается .github/workflows/scripts/redeliver-failed-deliveries.js в том же репозитории, где вы сохранили файл рабочего процесса GitHub Actions выше.

JavaScript
const { Octokit } = require("octokit");

This script uses GitHub's Octokit SDK to make API requests. For more information, see "Скриптирование с помощью REST API и JavaScript."

async function checkAndRedeliverWebhooks() {
  const TOKEN = process.env.TOKEN;
  const REPO_OWNER = process.env.REPO_OWNER;
  const REPO_NAME = process.env.REPO_NAME;
  const HOOK_ID = process.env.HOOK_ID;
  const LAST_REDELIVERY_VARIABLE_NAME = process.env.LAST_REDELIVERY_VARIABLE_NAME;
  const HOSTNAME = process.env.HOSTNAME;
  const WORKFLOW_REPO_NAME = process.env.WORKFLOW_REPO_NAME;
  const WORKFLOW_REPO_OWNER = process.env.WORKFLOW_REPO_OWNER;

Get the values of environment variables that were set by the GitHub Actions workflow.

  const octokit = new Octokit({ 
    baseUrl: "http(s)://HOSTNAME/api/v3",
    auth: TOKEN,
  });
  try {

Create an instance of Octokit using the token and hostname values that were set in the GitHub Actions workflow.

    const lastStoredRedeliveryTime = await getVariable({
      variableName: LAST_REDELIVERY_VARIABLE_NAME,
      repoOwner: WORKFLOW_REPO_OWNER,
      repoName: WORKFLOW_REPO_NAME,
      octokit,
    });
    const lastWebhookRedeliveryTime = lastStoredRedeliveryTime || (Date.now() - (24 * 60 * 60 * 1000)).toString();

Get the last time that this script ran from the configuration variable. If the variable is not defined, use the current time minus 24 hours.

    const newWebhookRedeliveryTime = Date.now().toString();

Record the time that this script started redelivering webhooks.

    const deliveries = await fetchWebhookDeliveriesSince({
      lastWebhookRedeliveryTime,
      repoOwner: REPO_OWNER,
      repoName: REPO_NAME,
      hookId: HOOK_ID,
      octokit,
    });

Get the webhook deliveries that were delivered after lastWebhookRedeliveryTime.

    let deliveriesByGuid = {};
    for (const delivery of deliveries) {
      deliveriesByGuid[delivery.guid]
        ? deliveriesByGuid[delivery.guid].push(delivery)
        : (deliveriesByGuid[delivery.guid] = [delivery]);
    }

Consolidate deliveries that have the same globally unique identifier (GUID). The GUID is constant across redeliveries of the same delivery.

    let failedDeliveryIDs = [];
    for (const guid in deliveriesByGuid) {
      const deliveries = deliveriesByGuid[guid];
      const anySucceeded = deliveries.some(
        (delivery) => delivery.status === "OK"
      );
      if (!anySucceeded) {
        failedDeliveryIDs.push(deliveries[0].id);
      }
    }

For each GUID value, if no deliveries for that GUID have been successfully delivered within the time frame, get the delivery ID of one of the deliveries with that GUID.

This will prevent duplicate redeliveries if a delivery has failed multiple times. This will also prevent redelivery of failed deliveries that have already been successfully redelivered.

    for (const deliveryId of failedDeliveryIDs) {
      await redeliverWebhook({
        deliveryId,
        repoOwner: REPO_OWNER,
        repoName: REPO_NAME,
        hookId: HOOK_ID,
        octokit,
      });
    }

Redeliver any failed deliveries.

    await updateVariable({
      variableName: LAST_REDELIVERY_VARIABLE_NAME,
      value: newWebhookRedeliveryTime,
      variableExists: Boolean(lastStoredRedeliveryTime),
      repoOwner: WORKFLOW_REPO_OWNER,
      repoName: WORKFLOW_REPO_NAME,
      octokit,
    });

Update the configuration variable (or create the variable if it doesn't already exist) to store the time that this script started. This value will be used next time this script runs.

    console.log(
      `Redelivered ${
        failedDeliveryIDs.length
      } failed webhook deliveries out of ${
        deliveries.length
      } total deliveries since ${Date(lastWebhookRedeliveryTime)}.`
    );
  } catch (error) {

Log the number of redeliveries.

    if (error.response) {
      console.error(
        `Failed to check and redeliver webhooks: ${error.response.data.message}`
      );
    }
    console.error(error);
    throw(error);
  }
}

If there was an error, log the error so that it appears in the workflow run log, then throw the error so that the workflow run registers as a failure.

async function fetchWebhookDeliveriesSince({
  lastWebhookRedeliveryTime,
  repoOwner,
  repoName,
  hookId,
  octokit,
}) {
  const iterator = octokit.paginate.iterator(
    "GET /repos/{owner}/{repo}/hooks/{hook_id}/deliveries",
    {
      owner: repoOwner,
      repo: repoName,
      hook_id: hookId,
      per_page: 100,
    }
  );
  const deliveries = [];
  for await (const { data } of iterator) {
    const oldestDeliveryTimestamp = new Date(
      data[data.length - 1].delivered_at
    ).getTime();
    if (oldestDeliveryTimestamp < lastWebhookRedeliveryTime) {
      for (const delivery of data) {
        if (
          new Date(delivery.delivered_at).getTime() > lastWebhookRedeliveryTime
        ) {
          deliveries.push(delivery);
        } else {
          break;
        }
      }
      break;
    } else {
      deliveries.push(...data);
    }
  }
  return deliveries;
}

This function will fetch all of the webhook deliveries that were delivered since lastWebhookRedeliveryTime. It uses the octokit.paginate.iterator() method to iterate through paginated results. For more information, see "Скриптирование с помощью REST API и JavaScript."

If a page of results includes deliveries that occurred before lastWebhookRedeliveryTime, it will store only the deliveries that occurred after lastWebhookRedeliveryTime and then stop. Otherwise, it will store all of the deliveries from the page and request the next page.

async function redeliverWebhook({
  deliveryId,
  repoOwner,
  repoName,
  hookId,
  octokit,
}) {
  await octokit.request(
    "POST /repos/{owner}/{repo}/hooks/{hook_id}/deliveries/{delivery_id}/attempts",
    {
      owner: repoOwner,
      repo: repoName,
      hook_id: hookId,
      delivery_id: deliveryId,
    }
  );
}

This function will redeliver a failed webhook delivery.

async function getVariable({ variableName, repoOwner, repoName, octokit }) {
  try {
    const {
      data: { value },
    } = await octokit.request(
      "GET /repos/{owner}/{repo}/actions/variables/{name}",
      {
        owner: repoOwner,
        repo: repoName,
        name: variableName,
      }
    );
    return value;
  } catch (error) {
    if (error.status === 404) {
      return undefined;
    } else {
      throw error;
    }
  }
}

This function gets the value of a configuration variable. If the variable does not exist, the endpoint returns a 404 response and this function returns undefined.

async function updateVariable({
  variableName,
  value,
  variableExists,
  repoOwner,
  repoName,
  octokit,
}) {
  if (variableExists) {
    await octokit.request(
      "PATCH /repos/{owner}/{repo}/actions/variables/{name}",
      {
        owner: repoOwner,
        repo: repoName,
        name: variableName,
        value: value,
      }
    );
  } else {

      owner: repoOwner,
      repo: repoName,

Тестирование скрипта

Вы можете вручную активировать рабочий процесс для тестирования скрипта. Дополнительные сведения см. в разделе "[AUTOTITLE" и "Запуск рабочего процесса вручную](/actions/monitoring-and-troubleshooting-workflows/using-workflow-run-logs)".

Альтернативные методы

В этом примере используется GitHub Actions для безопасного хранения учетных данных и запуска скрипта по расписанию. Однако если вы предпочитаете запустить этот скрипт на сервере, который обрабатывает поставки веб-перехватчика, вы можете:
