尝试获取Docker Hub目录时范围不足

Question

我正在尝试获取Docker集线器的目录列表，但到目前为止，我只是在响应中遇到错误。我的理解是，我需要在目录请求中传递一个承载令牌，因此我首先要获得具有相关范围的令牌：

curl -u "username:password "https://auth.docker.io/token?service=registry.docker.io&scope=registry:catalog:*"

（这是使用我的Docker Hub帐户中的用户名/密码）

然后，我将返回的令牌传递给注册表：

curl -vL -H "Authorization: Bearer eyJhbGciOiJFUzI1NiIsInR5cCI6I(...)" https://registry-1.docker.io/v2/_catalog

响应该请求，我得到：

…这似乎要求我返回并获得我在上面输入的网址的授权。

应该可以吗？如果是这样，我想念什么？

我遇到了同样的问题，在docker支持下提出了这个问题，并得到以下答案：“目录端点不适用于Docker
Hub，因为该端点实际上列出了注册表上的所有存储库，并且我们将其禁用，因为它将列出所有存储库。 Docker Hub。”
