我有一个网络服务器，它接受来自 Git 客户端的传入连接并将它们重定向到git-http-backend。克隆效果很好，但推送失败：
$ git push -u origin

调查传入连接，以下是上面标记连接的请求标头的一些信息，这些信息失败了：
POST /foo.git/git-receive-pack HTTP/1.1" 200 -
Content-Type application/x-git-receive-pack-request
Accept application/x-git-receive-pack-result

我读取了 4 个字节，然后返回输出。我想知道，我在这里可能会想念什么。所以我假设客户端认为服务器支持智能 HTTP，但我没有实现它。
