你可以使用search commit API。它足够灵活，可以通过不同的限定词进行搜索，比如提交者用户名、作者、仓库、组织等。
请注意，运行搜索有时间限制，如果超过时间限制，API将返回在超时之前已经找到的匹配项，并且响应的incomplete_results属性设置为true，请在此处了解更多信息
下面是一个使用Octokit在GitHub org中搜索test字符串的示例
| 搜索GitHub提交消息 |在本地运行x1c 0d1x|
| --------------|--------------|

const text = 'test';
const org = 'github';
const query =`${text} org:${org}`;
const searchResult = await github.rest.search.commits({
  q: query
});
  
// In case there is a timeout running the query, you can use incomplete_results to check if there are likely more results
// for your query, read more here https://docs.github.com/en/rest/reference/search#timeouts-and-incomplete-results
const { items, total_count} = searchResult.data;
console.log(items.map(commit => commit.commit));
console.log(`Found ${total_count} commits for ${text} at GitHub org called ${org}`);

阅读这个：GitHub API文档在原始文档中说使用get get /repos/{owner}/{repo}/commits。错误可能是由此引起的。您应该重新查看文档。

await octokit.request('GET /repos/{owner}/{repo}/commits', {
  owner: 'octocat',
  repo: 'hello-world'
})

如果您检查响应，您可以看到消息列，也许这会有所帮助。
