我正在尝试在另一个项目更改某些文件时自动更新子模块的提交ID。我有一个.net webhook，我正在使用octokit.net库。
我可以在github文档（https://developer.github.com/v3/git/trees/#create-a-tree）中看到，在创建允许添加提交和路径的新树时，有一个子模块选项，但我无法使其工作。 Octokit还有NewTreeItem / TreeItem对象的子模块类型，但没有示例或文档。
我当前的代码在这里 - 目前我将提交sha作为sha参数传递，但我可以看到这是错误的，我需要在该repo上创建一个提交并使用该sha，我只是不在创建树之前知道如何做到这一点，而且我找不到任何文档：
public static async Task UpdateSubmoduleInBranch(string repo, string branchName, string submodulePath, string sha, string commitComment, GitHubClient github = null)
{
//hoping this will update the sha of a submodule
// url encode branch name for github operations
branchName = HttpUtility.UrlEncode(branchName);
if (github == null) github = GetClient();
var repoId = (await github.Repository.Get(Settings.GitHub.OrgName, repo)).Id;
RepositoriesClient rClient = new RepositoriesClient(new ApiConnection(github.Connection));
var branch = await rClient.Branch.Get(repoId, branchName);
var tree = await github.Git.Tree.Get(repoId, branchName);
var newTree = new NewTree { BaseTree = tree.Sha };
newTree.Tree.Add(new NewTreeItem
{
Mode = Octokit.FileMode.Submodule,
Path = submodulePath,
Type = TreeType.Commit,
Sha = sha
});
var createdTree = await github.Git.Tree.Create(repoId, newTree);
var newCommit = new NewCommit(commitComment, createdTree.Sha, new[] { branch.Commit.Sha });
newCommit.Committer = Settings.GitHub.Committer;
var createdCommit = await github.Git.Commit.Create(Settings.GitHub.OrgName, Settings.GitHub.AppName, newCommit);
var updateRef = new ReferenceUpdate(createdCommit.Sha, false);
await github.Git.Reference.Update(repoId, "heads/" + branchName, updateRef);
}
修改
如果其他人正在寻找这个，我解决了这个问题 - octokit api 不支持这个动作，即使它看起来像。
除了在PATCH Async requests with Windows.Web.Http.HttpClient class找到的PatchAsync方法外，以下代码对我有用：
public static async Task UpdateSubmoduleInBranch(string repo, string branchName, string submodulePath, string sha, string commitComment)
{
using (var client = new HttpClient())
{
try
{
//these headers authenticate with github, useragent is required.
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/vnd.github.v3+json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Settings.GitHub.AuthToken);
client.DefaultRequestHeaders.UserAgent.Add(new ProductInfoHeaderValue("mathspathway-environment-manager", "v1.0"));
var committer = Settings.GitHub.Committer;
//get the branch, and collect the sha of the current commit
var branchResponse = await client.GetAsync($"{Settings.GitHub.ApiUrl}/repos/{Settings.GitHub.OrgName}/{repo}/branches/{branchName}");
JToken branchResult = JToken.Parse(await branchResponse.Content.ReadAsStringAsync());
var currentCommitSha = branchResult["commit"].Value<string>("sha");
//create the new tree, with the mode of 160000 (submodule mode) and type of commit, and the sha of the other
//repository's commit that you want to update the submodule to, and the base tree of the current commit on this repo
var newTreeObj = new
{
base_tree = currentCommitSha,
tree = new List<Object> { new { path = submodulePath, mode= "160000", type = "commit", sha = sha}
}
};
HttpContent treeHttpContent = new StringContent(JsonConvert.SerializeObject(newTreeObj));
var treeResponse = await client.PostAsync($"{Settings.GitHub.ApiUrl}/repos/{Settings.GitHub.OrgName}/{repo}/git/trees", treeHttpContent);
var treeResponseContent = JToken.Parse(await treeResponse.Content.ReadAsStringAsync());
var treeSha = treeResponseContent.Value<string>("sha");
//Create a new commit based on the tree we just created, with the parent of the current commit on the branch
var newCommitObj = new
{
message = commitComment,
author = new { name = committer.Name, email = committer.Email, date = committer.Date },
parents = new[] { currentCommitSha },
tree = treeSha
};
HttpContent newCommitContent = new StringContent(JsonConvert.SerializeObject(newCommitObj));
var commitResponse = await client.PostAsync($"{Settings.GitHub.ApiUrl}/repos/{Settings.GitHub.OrgName}/{repo}/git/commits", newCommitContent);
var commitResponseContent = JToken.Parse(await commitResponse.Content.ReadAsStringAsync());
var commitSha = commitResponseContent.Value<string>("sha");
//create an update reference object, and update the branch's head commit reference to the new commit
var updateRefObject = new { sha = commitSha, force = false };
HttpContent updateRefContent = new StringContent(JsonConvert.SerializeObject(updateRefObject));
var updateRefResponse = await client.PatchAsync($"{Settings.GitHub.ApiUrl}/repos/{Settings.GitHub.OrgName}/{repo}/git/refs/heads/{branchName}", updateRefContent);
} catch (Exception ex)
{
Debug.WriteLine($"Error occurred updating submodule: {ex.Message}{Environment.NewLine}{Environment.NewLine}{ex.StackTrace}");
}
}
}
答案 0 :(得分：0)
在尝试完成大致相同的目标时，但是通过单独的用户提交拉取请求，我给您的原始代码注射了一些小的更改。结果是它与Octokit.net完美配合。
var submoduleRepoId = (await gitHubClient.Repository.Get(submoduleRepoOwnerName, submoduleRepoName)).Id;
var submoduleRepoBranchLatestSha = (await gitHubClient.Git.Tree.Get(submoduleRepoId, submoduleRepoBranchName)).Sha;
…
var updateParentTree = new NewTree { BaseTree = parentRepoBranchLatestSha };
updateParentTree.Tree.Add(new NewTreeItem
{
Mode = FileMode.Submodule,
Sha = submoduleRepoBranchLatestSha,
Path = pathToSubmoduleInParentRepo,
Type = TreeType.Commit,
});
var newParentTree = await gitHubClient.Git.Tree.Create(pullRequestOwnerForkRepoId, updateParentTree);
var commitMessage = $"Bump to {submoduleOwnerName}/{submoduleRepoName}@{submoduleCommitHash}";
var newCommit = new NewCommit(commitMessage, newParentTree.Sha, parentBranchLatestSha);
var pullRequestBranchRef = $"heads/{pullRequestBranchName}";
var commit = await gitHubClient.Git.Commit.Create(pullRequestOwnerName, parentRepoName, newCommit);
var await gitHubClient.Git.Reference.Update(pullRequestOwnerForkRepoId, pullRequestBranchRef, new ReferenceUpdate(commit.Sha));
此时，我只能看到一些潜在的差异。
HttpUtility.UrlEncode我的分支名称（Octokit必须为我做任何所需的编码）可能是那些差异已经足够，或者当你尝试同样的事情时，可能已经解决了这个问题。
