创建基于 ssh 的远程路径

Question

如何设置 url 以将基于 ssh 的 remote 路径添加到已初始化的存储库？我试过

git_remote_create(&remote, repo, "origin", "ssh://git@github.com/libgit2/TestGitRepository");

但它没有 fetch 正确并且 git_remote_stats returns 0 收到对象。如果 ssh 替换为 https，git_fetch 将按预期工作。 ~~相同的 url 与 git_clone~~ 配合使用效果很好（见评论）：

git_clone(&repo, "ssh://git@github.com/libgit2/TestGitRepository", "foo", &clone_opts);

我也试过设置ssh://git@github.com:libgit2/TestGitRepository，但是也没用

Answer 1

检查是否git_remote_create_with_opts would work better, as in this test

git_remote *remote;
git_strarray array;
git_remote_create_options opts = GIT_REMOTE_CREATE_OPTIONS_INIT;

opts.name = "test-new";
opts.repository = _repo;
opts.fetchspec = "+refs/*:refs/*";

cl_git_pass(git_remote_create_with_opts(&remote, TEST_URL, &opts));

问题是因为我没有使用凭据回调。

来自 libgit2 中的回调部分 documentation:

For a credentials example, check out the fetch example, which uses an interactive credential callback. See also the built-in credential helpers.

下面是一个使用 ssh 初始化+获取+签出存储库的最小示例：

#include <git2.h>
#include <string.h>

int credentials_cb(git_credential **out, const char *url, const char *username_from_url,
    unsigned int allowed_types, void *payload)
{
  int err;
  char *username = NULL, *password = NULL, *privkey = NULL, *pubkey = NULL;
  username = strdup("git");
  password = strdup("PASSWORD");
  pubkey = strdup("/home/user/.ssh/id_rsa.pub");
  privkey = strdup("/home/user/.ssh/id_rsa");

  err = git_credential_ssh_key_new(out, username, pubkey, privkey, password);

  free(username);
  free(password);
  free(privkey);
  free(pubkey);

  return err;
}

int main(void)
{

  git_repository *repo;

  git_libgit2_init();

  git_repository_init(&repo, "libgit2-test-ssh/", 0);

  git_remote *remote;
  git_remote_create(
      &remote, repo, "origin",
      "ssh://git@github.com/libgit2/TestGitRepository");

  git_fetch_options fetch_opts = GIT_FETCH_OPTIONS_INIT;
  fetch_opts.callbacks.credentials = credentials_cb;
  git_remote_fetch(remote, NULL, &fetch_opts, NULL);

  git_object *branch;
  git_revparse_single(&branch, repo, "remotes/origin/master");
  git_checkout_options checkout_opts = GIT_CHECKOUT_OPTIONS_INIT;
  git_checkout_tree(repo, branch, &checkout_opts);

  git_object_free(branch);
  git_remote_free(remote);

  git_repository_free(repo);
  git_libgit2_shutdown();

  return 0;
}
