 * target a lower API level. In the meantime, if you have support for method references you can use
 * an equivalence as a bi-predicate like this: {@code myEquivalence::equivalent}.

By default, MinIO supports path-style requests that are of the format <http://mydomain.com/bucket/object>. `MINIO_DOMAIN` environment variable is used to enable virtual-host-style requests. If the request `Host` header matches with `(.+).mydomain.com` then the matched pattern `$1` is used as bucket and the path is used as object. Read more about path-style and virtual-host-style [here](http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAPI.html).

Example:

### Canceling a Call ([.kt][CancelCallKotlin], [.java][CancelCallJava])

Use `Call.cancel()` to stop an ongoing call immediately. If a thread is currently writing a request or reading a response, it will receive an `IOException`. Use this to conserve the network when a call is no longer necessary; for example when your user navigates away from an application. Both synchronous and asynchronous calls can be canceled.

### *Path operations* with `APIRouter` { #path-operations-with-apirouter }

And then you use it to declare your *path operations*.

Use it the same way you would use the `FastAPI` class:

{* ../../docs_src/bigger_applications/app_an_py39/routers/users.py hl[6,11,16] title["app/routers/users.py"] *}

You can think of `APIRouter` as a "mini `FastAPI`" class.

and use that one.

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts;C:\Windows\System32

That means that the system will now start looking first for programs in:

```

                    logger.warn(
                            "The project {} uses prerequisites"
                                    + " which is only intended for maven-plugin projects "
                                    + "but not for non maven-plugin projects. "
                                    + "For such purposes you should use the maven-enforcer-plugin. "

它们会为每个*路径操作*进行单独检查。

## 查看文档

打开 API 文档，进行身份验证，并指定要授权的作用域。

<img src="/img/tutorial/security/image11.png">

没有选择任何作用域，也可以进行**身份验证**，但访问 `/uses/me` 或 `/users/me/items` 时，会显示没有足够的权限。但仍可以访问 `/status/`。

如果选择了作用域 `me`，但没有选择作用域 `items`，则可以访问 `/users/me/`，但不能访问 `/users/me/items`。

这就是通过用户提供的令牌使用第三方应用访问这些*路径操作*时会发生的情况，具体怎样取决于用户授予第三方应用的权限。

## 关于第三方集成

本例使用 OAuth2 **密码**流。

这种方式适用于登录我们自己的应用，最好使用我们自己的前端。
