github api for java使用踩坑之getStats总是null

github有一系列api作为查询的接口，同时还有用各种语言封装的版本。详情<a href="https://developer.github.com/v3/repos/branches/">点击这里</a>

 

当我今天打算调用getStats()方法时遇到了很坑的问题：返回值总是Null

代码如下：

GitHubClient client = new GitHubClient();
client.setCredentials("username", "password");
CommitService coms = new CommitService(client);
RepositoryService service = new RepositoryService(client);
Repository repo = service.getRepository("BokunoMasayume","bootstrap-note");
for(RepositoryCommit rc : coms.getCommits(repo)){
    System.out.println("total: "+rc.getStats());
    }

我去查了github的原始api，发现当查询一个仓库的所有commits时，返回的commit列表中的每个commit信息都有所省略，而stats这个属性正好被省略了，

而在通过commit-sha和仓库查询的单个commit信息中有stats属性

commit集：https://api.github.com/repos/BokunoMasayume/bootstrap-note/commits

特定commit：https://api.github.com/repos/BokunoMasayume/bootstrap-note/commits/3084c0a49fbca0c496abac80191f04b929141d95

于是我在代码中加了一行<code>rc = coms.getCommit(repo, rc.getSha());</code>，将列表中的RepositoryCommit对象变成了单独（理解意思就好）的RepositoryCommit对象,果然，再次运行getStats正常了。

GitHubClient client = new GitHubClient();
client.setCredentials("username", "password");
CommitService coms = new CommitService(client);
RepositoryService service = new RepositoryService(client);
Repository repo = service.getRepository("BokunoMasayume","bootstrap-note");
for(RepositoryCommit rc : coms.getCommits(repo)){
    rc = coms.getCommit(repo, rc.getSha());
    System.out.println("total: "+rc.getStats().getTotal);
    }
