* list (as in Python list): list
* context manager: context manager (do not translate to "gestor de contexto" or "administrador de contexto")
* a little bit: un poquito
* graph (data structure, as in "dependency graph"): grafo (do not translate to "gráfico")
* form data: form data (do not translate to "datos de formulario" or "datos de form")
* import (as in code import): import (do not translate to "importación")

This includes work such as compiling, testing and documenting software, plus sharing that software via publishing and dependency management.
This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.

首先，创建 Pydantic 用户模型。

与使用 Pydantic 声明请求体相同，并且可在任何位置使用：

{* ../../docs_src/security/tutorial002_an_py310.py hl[5,12:6] *}

## 创建 `get_current_user` 依赖项 { #create-a-get-current-user-dependency }

创建 `get_current_user` 依赖项。

还记得依赖项支持子依赖项吗？

`get_current_user` 使用 `oauth2_scheme` 作为依赖项。

与之前直接在路径操作中的做法相同，新的 `get_current_user` 依赖项从子依赖项 `oauth2_scheme` 中接收 `str` 类型的 `token`：

 * allowing for URL-based client selection. Clients can be added with specific patterns
 * and optionally at specific positions in the processing order.</p>
 *
 * <p>This factory is typically initialized through dependency injection and can be
 * configured with initialization parameters that are passed to all registered clients.</p>
 *
 * <p>Features:</p>
 * <ul>
 *   <li>Pattern-based client mapping</li>

### Testing
```bash
mvn test                                    # Run unit tests (*Test.java)
mvn test -Dtest=ClassName                   # Run single unit test

# To install fess jar for plugin dependency resolution:
# Change pom.xml <packaging>war</packaging> to <packaging>jar</packaging> first
mvn clean install -DskipTests               # Then revert packaging back to war

        }

        return Collections.unmodifiableList(errorArtifactExceptions);
    }

    // Circular Dependency Exceptions
    // ------------------------------------------------------------------------
